Next, a more detailed configuration and operation of the fertilizer selection system 10 according to the present embodiment will be described. As an example,
The selection of compound fertilizers for rice cultivation in Japan is discussed. In general, this type of compound fertilizer for rice is a combination of a chemical fertilizer that works as a base fertilizer and a coated fertilizer that works as a tiller and panicle fertilizer. The coated fertilizer is a coated nitrogen fertilizer (coated urea, coated chemical, etc.). ) Is used. In other words, the amount of nutrient that controls the fertilizing properties is mainly nitrogen, which is an essential component for growing rice. For this reason, unless otherwise specified, the nutrient amounts appearing in the following description shall mean the nitrogen nutrient amounts.

(1) Cultivation Information File 11 The cultivation information file 11 stores in advance standard fertilization time and customary fertilization information for each cultivar in each region of Japan. FIG. 2 shows a configuration example of the cultivation information file 11. The cultivation information file 11 of this example includes a set of records 110 for each cultivar in each region,
One record 110 includes items of a record ID 111, a region name 112, a variety name 113, a fertilization time 114, and customary fertilization information 115. In the area name 112, for example, a prefecture name is set. Of course, each unit such as the southern part of the prefecture, the northern part of the prefecture, etc. may be divided into several units with similar climates, and individual units may be set, and names indicating smaller areas such as municipalities may be set. . In the variety name 113, the name of a rice variety (for example, Koshihikari) is set. In the fertilization time 114, a sowing time of the variety in the area is set. In the customary fertilization information 115, information on a base fertilizer that is conventionally fertilized in cultivation of the variety in the area is set. The information of the basal fertilizer is set, for example, by the application rate of a predetermined cropping area (for example, 10 are = 100 square meters) of the nitrogen (N), phosphorus (P), and potassium (K) components. The fertilizer may be described and the application rate may be set.

(2) Input control means 15 The input control means 15 starts the processing shown in FIG. 3 when activated by an instruction from the input device 23 in FIG. 1, for example. First, one record 110 is input from the cultivation information file 11 (S1501), and the area name 112, the cultivar name 113, the fertilization time 114, and the customary fertilization information 115 in the record 110 are input to the compound fertilizer designing means 16, and the design is performed. (S1503). Next, the intermediate file creating means 1
7 waits for the notification that the information of the compound fertilizer designed by the compound fertilizer designing means 16 has been registered in the intermediate file 12 to be issued (S1504), and upon receiving the notification, returns to step S1501 and returns to step S1501. Similar processing is repeated for the next record 110 in the file 11. When the processing for all the records 110 stored in the cultivation information file 11 is completed (YE in S1502)
S), the product integration means 18 is activated (S1505), and FIG.
Finish the process.

(3) Compound fertilizer design means 16 In this embodiment, compound fertilizer design means 16 is described in Reference 1.
Utilizing the compound fertilizer design system described in (1). FIG. 4 shows an example of the overall processing of the compound fertilizer designing means 16. The compound fertilizer design means 16 receives the area name 11 from the input control means 15.
2. When the cultivar name 113, the fertilization time 114 and the customary fertilization information 115 are inputted (S1601), first, the type and the compounding amount of the chemical fertilizer are determined, and the required nutrient amount over time by the coated fertilizer is calculated (S1602). FIG. 5 shows the details of step S1602.

First, the required nutrient amount with time of the crop of the variety is read from the crop information file 161 (S161).
1). The time required nutrient amount of the crop means the nutrient amount required at each stage of the growing process of the crop. The required nutrient amount over time of the crop is obtained by dividing the period in which the crop is cultivated into predetermined time units (for example, 5 days) starting from the start of cultivation for each crop, and calculating the required amount per unit planted area for each time unit. The array of nutrient amounts is stored in the crop information file 161 in advance. In step S1611, by searching the crop information file 161 using the input variety name 113 as a key, the required nutrient amount per unit area of the crop of the variety is acquired over time.

Next, the soil supply nutrient over time in the production area is read from the soil strength information file 162 (S1612). The time-dependent soil supply nutrient amount of the production site means a nutrient amount supplied from the soil of the production site yearly or at each time of cultivating the crop. The time-dependent soil supply nutrient amount of the production area is obtained by dividing the annual or crop cultivation period into predetermined time units (for example, 5 days) for each area, and dividing the soil supply nutrient amount per unit planted area for each time unit. Are stored in advance in the geodynamic information file 162 as an array of Step S1
In step 612, the soil strength information file 162 is searched using the input area name 112 as a key, thereby obtaining the time-dependent soil supply nutrient per unit planted area in the area.

Next, based on the input customary fertilization information 115, the type of the compound fertilizer is selected from the compound fertilizer list 163 and the amount of the compound fertilizer is determined (S1613). Chemical fertilizers are fertilizers that elute into the soil very quickly after fertilization and exhibit fertilizer effects, and are used to supply the required amount of NPK, which is the three major nutrients of plants, together with the required amounts of other trace elements. There are various products having different N, P, and K compounding ratios. The chemical fertilizer list 163 stores the specifications of such chemical fertilizer products in advance. The specifications are set, for example, in a format of “product name XYZ”. Here, X is the percentage of nitrogen (N) in the product weight,
Y is also the percentage of phosphorus (P), and Z is also the percentage of potassium (K). In step S1613,
N, P, indicated by the information of the base fertilizer in the customary fertilization information 115
K, N, P, K
Is selected from the chemical fertilizer list 163, and the amount of the chemical fertilizer is determined such that the weight of the nitrogen component matches the nitrogen application rate in the basic fertilizer information. . For example, the application rate of N, P, and K shown in the information of basal fertilizer per predetermined planting area is set to 2.8K.
Assuming that g, 6.3 Kg, and 5.0 Kg, the ratio of N, P, and K is approximately 4: 9: 7, and a chemical fertilizer product that matches or approximates the ratio is selected from the chemical fertilizer list 163. And
For example, assuming that the chemical fertilizer of “Product name 8-18-14” is selected, 2.8 kg ÷ 0.08 = 35 kg is determined as the usage amount (mixing amount) of the chemical fertilizer. Here, the amount used is determined based on nitrogen because the nitrogen component is most important for the growth of rice.

Next, the determined nutrient supply per unit amount of the compound fertilizer over time is read from the compound fertilizer information file 164 (step S1614). Nutrient supply over time per unit amount of the compound fertilizer is divided into predetermined time units (for example, 5 days) for each type of compound fertilizer, starting from the time of fertilization until the end of crop harvesting. Chemical fertilizer information file 1 as an array of nutrient supply for each time unit
64 in advance. In step S1614, the chemical fertilizer information file 164 is searched using the product name of the chemical fertilizer determined in step S1613 as a key, thereby obtaining the supply-time nutrient amount per unit amount of the chemical fertilizer. Then, in the next step S1615,
According to the ratio between the nitrogen application rate and the unit amount indicated in the basal fertilizer information, the time-dependent supply nutrient amount acquired in step S1614 is corrected, and the time-dependent supply when the chemical fertilizer is used only in the determined usage amount. Calculate the nutrient content.

Finally, based on the time-required nutrient amount of the crop for each unit time obtained in step S1611, step S16
In order to satisfy the time required nutrient amount of the crop by subtracting the time supply nutrient amount of the soil of the production place of each unit time obtained in 12 and the time supply nutrient amount of the chemical fertilizer of each unit time obtained in step S1615. The time required nutrient amount per unit planted area by the coated fertilizer, which needs to be eluted into the soil at each time after the fertilization by the coated fertilizer, is calculated (S1616). The calculated temporal required nutrient amount is obtained by dividing the period in which the crop is cultivated into predetermined time units (for example, 5 days), and temporarily storing the required nutrient amount for each time unit in the compound fertilizer design means 16. Is held.

After the calculation of the type and compounding amount of the chemical fertilizers and the required amount of nutrients with time by the coated fertilizer (S1602), next, for each of the predetermined coated fertilizers, the amount of the coating with the time change of the soil temperature is changed. Calculate the amount of fertilizer eluted over time (S
1603). FIG. 6 shows the details of step S1603. In addition, as each of the predetermined coated fertilizers, for example, a total of seven types of coated nitrogen fertilizers of a 20-day type, a 40-day type, a 60-day type, an 80-day type, a 100-day type, a 120-day type, and a 140-day type are set. Is done. An X-day type of fertilizer means a fertilizer that takes X days to elute 80% of the nitrogen component into water when the fertilizer is left in water at 25 ° C.

First, the temporal change of the ground temperature of the area is read from the weather information file 165 (S1621). The time-dependent change in the soil temperature means the soil temperature at each time of the year or the period of cultivating the crop. The time-dependent change of the soil temperature is obtained by dividing the annual or crop cultivation period into predetermined time units (for example, 5 days) for each region, and arranging the soil temperature (average soil temperature within each time unit) for each time unit. Is stored in the weather information file 165 in advance. Step S1621
Then, by searching the weather information file 165 using the input area name 112 as a key, the temporal change of the ground temperature of the area is obtained, and the temporal change of the ground temperature after the seeding period given at the fertilization time 114 is obtained. Extract.

Next, the time-dependent elution amount of the coated fertilizer per unit fertilizer amount at a fixed temperature is read from the coated fertilizer information file 166 for each type of the predetermined coated fertilizer (S1622). The amount of coated fertilizer eluted per unit fertilizer over time at a certain temperature is the amount of unit fertilizer that is applied at each time from the start of fertilization to the end of harvesting at a constant ambient temperature. It means the amount of nutrient eluted from fertilizer. The time-dependent elution amount of the coated fertilizer per unit fertilizer amount is determined by a predetermined time unit (for example, 5 hours) from the start of fertilization to the end of harvesting for each type of coated fertilizer and for each ambient temperature. Days) and stored in advance in the coated fertilizer information file 166 as an array of the amount of fertilizer eluted for each time unit. Step S1622
Then, the time-dependent elution amount of each coated fertilizer at each ambient temperature stored in the coated fertilizer information file 166 is read.

Next, the elution amount of the fertilizer at the temperature equal to the ground temperature read out in step S1622 is sequentially applied to the ground temperature for each time unit extracted in step S1621 for each type of the predetermined coated fertilizer. Then, the time-dependent elution amount of the coated fertilizer per unit fertilizer amount according to the time-dependent change of the soil temperature is calculated (S1623). That is, for each type of coated fertilizer, the period from the time of fertilization to the end of harvesting is divided into unit times (for example, 5 days), and each time unit taking into account the time-dependent change of the soil temperature at the production site is considered. The sequence of the elution amount per unit amount of the coated fertilizer is calculated and stored internally.

After the calculation of the amount of the coated fertilizer eluted per unit amount due to the change of the soil temperature over time (S1603), the optimal combination of the coated fertilizers and the amount of each coated fertilizer are determined. (S1604). This processing is performed so that the time-dependent elution amount of the compounded fertilizer obtained by compounding one or more fertilizers selected from the coated fertilizer group matches or approximates the time-dependent required nutrient amount calculated in step S1602. This is a process of selecting one or more types of coated fertilizers and determining the blending amount of each selected coated fertilizer. FIG. 7 shows the details of step S1604.

First, candidates for a combination of coated fertilizers are determined (S1631). Specifically, a random number is generated for each predetermined type of coated fertilizer, and when the random number is equal to or greater than a predetermined value, the coated fertilizer is selected, and other than that, no selection is made. If the number of coated fertilizers selected by this method is 1 or more and equal to or less than a predetermined maximum number, the selected coated fertilizer is set as a combination candidate. On the other hand, if the number of the selected coated fertilizers is not 1 or more and not more than the predetermined maximum number, a random number is generated again for each coated fertilizer, and the procedure returns to the step of determining the selected coated fertilizer.

Next, candidates for the amount of each coated fertilizer in the combination determined in step S1631 are determined (S1632). Specifically, the amount of each coated fertilizer is determined by a random number.

Next, the time-dependent elution amount of the compound fertilizer composed of the combination of the coated fertilizer determined in step S1631 and the compound amount determined in step S1632 is calculated for each of the coated fertilizers calculated in step S1603. Is calculated from the time-dependent elution amount per unit amount and the above-mentioned compounding amount, and the degree of coincidence between the calculated time-dependent elution amount of the compounding fertilizer and the temporal necessary nutrient amount calculated in step S1602 is calculated ( S1633). As the degree of coincidence, for example, the entire period in which the crop requires fertilizer is divided into predetermined time units (for example, 5 days), and the square of the difference between the required nutrient amount over time and the elution amount over time in each time unit Is used over the entire period. In this case, the smaller the degree of coincidence, the closer the elution amount of the compound fertilizer over time is to the required amount of nutrients of the crop over time, indicating that the compound fertilizer is appropriately compounded.

The above-described processing is repeated a predetermined number of times (S1634), and those having a low degree of coincidence are determined as the optimal combination of coated fertilizers and the optimal blending amount of each coated fertilizer (S1635).

In this embodiment, the candidates for the combination of fertilizers and the candidates for the compounding amount are determined by random numbers.
They may be determined in other ways. As another method, as a method for determining the composition more efficiently, for example, as described in Reference 1, a combination of fertilizers is determined by a genetic algorithm using a chromosome corresponding to a gene for a coated fertilizer. Alternatively, the compounding amount of each selected coated fertilizer may be determined by a method of optimizing an evaluation function based on the required amount of nutrient over time and the elution amount of the compounded fertilizer over time.

When the optimum combination of the coated fertilizers and the optimum compounding amount of each coated fertilizer are determined as described above, the area name, the product name, and the design result input from the input control means 15 are transmitted to the intermediate file creating means 17. Output (S16 in FIG. 4)
05). The design result includes the optimum combination and amount of the coated fertilizer determined in step S1604, and step S1604.
The type and compounding amount of the chemical fertilizer determined in 1602 are included. The optimal combination and amount of the coated fertilizer are, for example, 20-day type, 40-day type, 60-day type, 80-day type, 100-day type, 120-day type,
It is shown in an array of the amount (including 0) of each coated fertilizer of the 140-day type.

(4) Intermediate File Generating Unit 17 The intermediate file generating unit 17 starts the processing shown in FIG. 8 when the area name, the variety name, and the design result are output from the compound fertilizer designing unit 16. First, a region name, a product name, and a design result are input (S1701), and then a product name is assigned (S1).
702). As long as the product name is unique, it may be a name represented by a character string, a product code represented by a numerical value, or may include both a name and a product code. Next, an intermediate record is created (S1703) and registered in the intermediate file 12 (S1704). Then, the input control means 15 is notified that the information of the compound fertilizer designed by the compound fertilizer designing means 16 has been registered in the intermediate file 12 (S1705).

FIG. 9 shows a configuration example of the intermediate file 12.
The intermediate file 12 in this example is composed of a set of intermediate records 120 for each cultivar in each region, and one record 120 is composed of a record ID 121, a region name 122, a variety name 123, a type and an amount 124 of coated fertilizer. , The type and compounding amount 125 of the chemical fertilizer, and the product name 126. In addition, the types and amounts 124 of the coated fertilizer are indicated by an array of the amounts of the coated fertilizers of each type. The intermediate file creating means 17 sets the area name, the variety name, the type and the amount of the coated fertilizer, and the type and the amount of the chemical fertilizer input from the compound fertilizer designing means 16 in the items 122 to 125, and sets the assigned product name. Item 126 is set and the record ID is set to item 121
Is created and additionally registered in the intermediate file 12.

(5) Product Integration Means 18 When the product integration means 18 is started by the input control means 15, it starts the processing shown in FIG. First, all intermediate records stored in the intermediate file 12 are input (S18).
01), compounding components (type of coated fertilizer and type of chemical fertilizer)
Classifies the same intermediate records into the same large group (S1
802). Next, attention is paid to one large group in a set of one or more large groups formed by this classification (S18).
03), execute the following processing.

First, the intermediate records belonging to the large group are determined by the compounding amount (the compounding amount of the coated fertilizer and the compounding amount of the chemical fertilizer).
Are matched or approximate to each other into the same small group (S1804). As will be described later, one fertilizer product is manufactured for each small group. Therefore, if the standard for judging the approximation is loosened, the final number of products will be reduced, but the accuracy will be poor. Improve but increase the number of products. For this reason, a criterion for determining an approximation in consideration of both circumstances is set in advance. Here, for example, those in which the difference in the mixing ratio of each type is within 3% with respect to the total mixing ratio of the coated fertilizer are classified into the same small group. Next, attention is paid to one small group in a set of one or more small groups formed by this classification (S180).
5) The same product name is set as the product name 126 of all intermediate records belonging to the small group (S1806). This may be unified with the product name set in any one of the intermediate records, or a new unique product name may be assigned. The same process is repeated for all the small groups belonging to the large group (S1807, S1807).
1808).

When the processing for one large group is completed, attention is shifted to the next large group in the unprocessed large group (S1809), and the same processing as described above is repeated (S1804 to S1810). When the processing for all the large groups is completed, the intermediate file 12 is overwritten with the processed intermediate record group (S1811). The configuration of the intermediate file 12 after overwriting is basically the same as that in FIG. However, the product name 126 indicates the intermediate record 12 in which the compounding components are the same and the compounding amount of each fertilizer is the same or similar.
