Examples 2 to 4 and comparative examples 1 to 2
Examples 2 to 4 and comparative examples 1 to 2 each provide a compound fertilizer for promoting plant growth and health, and differ from example 1 only in that: the raw material components of the compound fertilizer are different, and are specifically shown in table 1.
TABLE 1
Test example
The test example performs an application effect test on the compound fertilizers of examples 1 to 4 and comparative examples 1 to 2:
the test sites are: selecting 6 areas with the same soil conditions in the West river village in the Zhao county of Hebei, and correspondingly applying the compound fertilizers of the examples 1-4 and the comparative examples 1-2;
the test objects are: tomatoes;
the test method comprises the following steps:
and (3) plant coarseness: measuring the diameters of the middle parts of the second and third leaves at the base of the stem by using vernier calipers 3 months after the compound fertilizers of the embodiment and the comparative example are applied;
weight: after 3 months of applying the compound fertilizer of the embodiment and the comparative example, 10 meters in one ridge are randomly selected in 6 areas, tomatoes which meet the commodity condition are picked, and weighed by an electronic hand scale with the error of +/-0.01 jin.
Tomato growth vigor: observing the appearance;
soil: when the compound fertilizers of the embodiment and the comparative example are applied for 30 days, a soil sample of 10cm is taken in each area, 5 soil samples are taken in a test field by a five-point sampling method, the soil is mixed into 1 soil sample, and the soil is air-dried and the volume weight, total nitrogen, available phosphorus, available potassium, pH value and CEC of the soil are detected.
The test results are shown in tables 1 and 2 below:
TABLE 1
| Plant diameter | Weight (jin) | Tomato growth vigor | |
| Example 1 | 1.17 | 5.95 | Less cracked fruit and uniform fruit |
| Example 2 | 1.13 | 5.56 | More dehiscent fruits and more uniform fruits |
| Example 3 | 1.00 | 5.00 | Less fruit cracking and uniform fruit |
| Example 4 | 1.05 | 5.13 | Less cracked fruit and uniform fruit |
| Comparative example 1 | 0.95 | 4.98 | Increased fruit cracking and different fruit sizes |
| Comparative example 2 | 0.84 | 4.73 | More cracked fruits and even fruits |
| Comparative example 3 | 0.65 | 3.98 | More dehiscent fruits and more uniform fruits |
TABLE 2
Comparing examples 1-3 with comparative example 2, it can be seen that, as the amount of the natural ulva to adsorb the sol agent is reduced, the nutrient elements cannot be effectively transported, resulting in the reduction of the diameter and weight of the plant, and meanwhile, the amount of the natural ulva to adsorb the sol agent is reduced, and the amount of the natural ulva to adsorb the chemical fertilizer in the soil is also reduced, so that the contents of nitrogen, phosphorus and potassium in the soil are higher.
Comparing examples 1 and 4, it can be seen that when the dosage of the natural ulva water absorption sol is constant, the capture function of enough organic chelating agent is lacked, so that the nutrient elements can not be effectively transported, the diameter and weight of the plant are reduced, and the content of nitrogen, phosphorus and potassium in the soil is high.
Comparing examples 1, 2 and 3 with comparative examples 1 and 3, it can be seen that the usage amounts of the pistacia chinensis bunge extract and the humic acid solution derived from enzymolysis minerals are close and better, the tomato has more fruit cracking and uneven fruit size due to the increase of the usage amount of the pistacia chinensis bunge extract, and the diameter and the weight of the tomato plant are reduced due to the reduction of the usage amount of the humic acid solution derived from enzymolysis minerals (comparative example 3).
While embodiments of the present invention have been described above, the above description is illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
