Abstract

PURPOSE:To provide the fertilizer with which fertilization with a proper amt. of the fertilizers by a suitable means is possible without soiling the hands and a fertilization method therefor. CONSTITUTION:This packaged fertilizer 1 is constituted by sealing the prescribed amt. each of plural granular fertilizers 2 of about 2, 3mm diameter into respective bags 3. The bag 3 is constituted of coarse meshed water permeable man- made paper to the extent that the fertilizers 2 do not spill. The paper is two- folded and its three sides are fixed by heat sealing, etc., to a hermetic state. The individual fertilizers 2 sealed into the bag 3 are the coated fertilizers 2 completely coated with films. Components, such as nitrogen, phosphoric acid and potassium, compounded to be suitable for the plants to be fertilized are compounded as the fertilizer components of the fertilizers 2 themselves and are hermetically sealed within the films. These components are so adjusted that the fertilizers 2 dissolve slowly by spending the prescribed period, by which concn. hazards are eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fertilizer placed on soil to provide nutrients to flowers and flowers planted in large-scale seedling raising facilities, pots and planters, and plants planted in gardens, and the like. It relates to the fertilization method.

[0002]

2. Description of the Related Art Conventionally, fertilization of flowers and plants, especially topdressing, is applied to soil every 20 days, for example, in accordance with the growth of plants. The fertilizer application method is to apply a predetermined amount of powdered or granular fertilizer containing ingredients such as nitrogen, phosphoric acid and potassium according to the target plant and soil to the soil surface away from the target plant. In some cases, the soil on the surface layer was mixed with the above-mentioned fertilizer, or it was placed so as to be buried shallowly and fertilized, and then watered to dissolve the fertilizer into the soil.

[0003] However, when fertilizer is applied by spraying unpackaged fertilizer as described above, the fertilizer applied at the time of irrigation diffuses to cause root damage, or scatters out of the pot to cause passages or under shelves. There are problems such as getting dirty. And
As a conventional fertilizer and fertilizer application method for avoiding this problem, for example, a quarterly paper “Fertilizer Time Report”, published by the Institute for Fertilizer Economic Research, 1992-No. 1 (July 25, 1992)
(Issued daily), P42 to P44.

This is a fertilizer in which rapeseed meal and bone meal are sufficiently stirred at a ratio of 2 to 1 with a stirrer, and the powdered fertilizer is enclosed in a non-woven bag. The fertilizer was applied by placing it in the soil around the plant according to the growth of the plant to avoid the above problems.

[0005]

However, in the above-mentioned packaged fertilizer, since the fertilizer to be enclosed in the bag is in powder form, the fertilizer may spill out of the bag when carrying the bag. In order to prevent it from happening, we have to use a bag with dense eyes, which easily causes clogging during fertilization.
As a result, the outflow of fertilizer components decreases in a short period of time, and the amount of fertilizer supplied to the soil becomes unstable, so there is a problem that fertilizer cannot be supplied for a long period of time.

When the above-mentioned clogging occurs, it is impossible to elute a predetermined fertilizer component unless water is applied slowly. Further, since the fertilizer is in powder form, if the bag is strongly gripped, powder may blow out from the bag and stain clothes or the like. There is also a problem that the powdered fertilizer in the bag is hardened in a lump due to moisture absorption and is difficult to be eluted.

Further, when organic fertilizers such as rapeseed meal and bone meal are enclosed in a bag as in the above-mentioned conventional method, ammonia as a fertilizer component is volatilized in a short period of time, and long-term storage is not possible, and odor is not generated. It is not suitable for use by amateurs such as home gardening, as it is prone to swelling and insects and the like. The present invention has been made by paying attention to the problems as described above, and a packaged fertilizer and a fertilizer application method thereof which can stably supply an appropriate amount of fertilizer by a simple means without soiling the hands. It is intended to be provided.

[0008]

In order to achieve the above object, the packaged fertilizer of the present invention is characterized in that a predetermined amount of granular fertilizer is enclosed in a water-permeable bag. The granular fertilizer preferably has a particle size of 1 to 5 mmφ, more preferably 2 to 4 mmφ.

As the fertilizer to be enclosed, coated fertilizer may be used. Then, the above-mentioned packaged fertilizer is placed on the soil surface around the plant and water is applied to perform fertilization.

[0010]

[Function] By applying a predetermined amount of one or more kinds of fertilizers appropriately mixed according to the target plant in a bag in advance, the fertilizer operator can put the bag into the soil area or the like. In addition, place the required number of bags on the soil surface. Then, since the whole fertilizer enclosed in the bag has a predetermined fluidity, the lower surface of the bag is transformed into a shape that can be engaged with the soil surface on which it is placed, and is adapted to the soil surface.

At this time, since the granular fertilizer is enclosed in the bag, when the packaging fertilizer is dropped on the way or when it is found that the place for placing it on the soil surface is inappropriate, it is scattered in the conventional case. Since the fertilizer is not scattered, you can simply lift the bag and move it to the desired location. Also,
Fertilizers do not directly touch the fertilizer during fertilization, so they do not stain their hands or clothes.

In particular, if the fertilizer is in the form of powder, there is a risk that the powder in the bag will be blown out by the impact of dropping it or by strongly pressing the bag, but since the fertilizer in this embodiment is granular, Such things are suppressed. And with watering can,
If you give water to the bag placed on the soil surface,
Water enters the bag and contacts the fertilizer enclosed in the bag to dissolve the fertilizer. Then, the ionized fertilizer elutes from the lower part of the bag together with water and dissolves in the soil.

In particular, since the size of the bag eyes is such that the granular fertilizer does not fall off, a bag having good water permeability and air permeability can be used, and clogging of the bag can be prevented. Therefore, as compared with the conventional packaged fertilizer, the decrease in the outflow of the fertilizer component with time is suppressed, and the stable fertilizer component can be supplied to the soil for a long period of time. Further, in the granular fertilizer, the fertilizers do not solidify in a lump form due to moisture absorption, as compared with the powdered fertilizer, so that the fertilizer component can be stably eluted over a long period of time.

Further, when the coated fertilizer is enclosed in the bag as the granular fertilizer, even if a large amount of fertilizer is applied, the concentration failure does not occur, so that the number of additional fertilizers can be greatly reduced and moisture absorption can be performed. Long-term storage is possible without the coated fertilizer in the bag solidifying. Then, by removing the bag from the soil after the end of the planned fertilizer elution period, by-products such as the dregs and elution residue of the coated portion of the fertilizer can be easily removed.

Further, depending on the plant, when the supply of the fertilizer component is stopped during the growth, the yield, quality, and flower retention of the plant may be improved. In particular, nitrogen interruption during the flower bud differentiation of strawberry is well known. In the present invention, the bag before the end of the fertilizer effective period for which fertilization has been applied may be taken out from the soil at the time when the fertilizer content must be interrupted.

If the material forming the bag is one that is corroded / decomposed by microorganisms in the soil after a certain period of time, even if the fertilizer elution period is over, the bag is left to be left to corrode / decompose. I don't mind.

[0017]

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the packaging fertilizer 1 is configured by enclosing a predetermined amount of a plurality of granular fertilizers 2 having a diameter of about 2 to 3 mm in each bag 3. The bag 3 is made of a water-permeable synthetic fiber non-woven fabric having a coarse mesh so that the fertilizer 2 does not spill, and is folded in two and fixed on three sides by heat welding or the like to be in a sealed state.

The individual fertilizers 2 enclosed in the bag 3 contain polyolefins, olefin-based copolymers, vinylidene chloride polymers and copolymers as the main components of the binder. A coated fertilizer 2 which is completely coated with a film containing 50% w or more and 80% w or less of water-insoluble or sparingly water-soluble inorganic powder, which is the target fertilizer component of the fertilizer 2 itself. Ingredients such as nitrogen, phosphoric acid, potash, etc., which are suitable for No. 6, are mixed and sealed in the film, and the fertilizer 2 is adjusted so as to dissolve slowly over a predetermined period so that there is no concentration disorder. There is.

As the fertilizer to be sealed in the coated fertilizer, organic fertilizers such as rapeseed meal, bone meal and fish meal, and inorganic fertilizers such as ammonium sulfate, ammonium phosphorus and chemical fertilizers are considered.
From the viewpoint of odor and long-term storability, it is preferable to apply an inorganic fertilizer. Then, as shown in FIG. 2, the packaged fertilizer 1 configured as described above is placed on the surface of the soil 5 in the pot 4 or planter or the soil 5 around the plant, and watered with a watering can as appropriate. Fertilization is carried out.

By sprinkling the above water, the water enters the bag 3 to dissolve the fertilizer 2 in the bag 3 and the ionized fertilizer component is
It elutes from the lower surface of the bag 3 together with water and dissolves in the soil 5. Then, the dissolved fertilizer 2 is absorbed by the plant 6 as a nutrient from the root in the ground. The amount of the fertilizer 2 stored in each of the above-mentioned packaged fertilizers 1 is constant, and a plurality of packaged fertilizers 1 may be placed on the surface of the soil 5 according to the soil area, etc.
The amount of fertilizer applied can be easily specified.

As described above, since the packaged fertilizer 1 can be applied on the surface of the soil 5 simply by watering it, a fixed amount of the fertilizer 2 required when an amateur makes vegetables with a planter or the like.
Can be applied by simple means. Particularly, in the packaged fertilizer 1, since the fertilizer 2 in the bag is a granular coated fertilizer, the fertilizer 2 does not elute outside the bag 3 unless it contains a predetermined amount of water or more. Therefore, fertilizer 2 can be applied without soiling the hands, and even if it is accidentally dropped on the floor, fertilizer 2
Is not scattered.

When watering with a watering can,
Even if the water directly hits the packaged fertilizer 1, the fertilizer 2 itself does not fly out of the pot 4 or adhere to the plants 6 to cause fertilization, and the bag serves as an anchor and the water is overdone. The fertilizer 2 can be prevented from running away. In particular,
Since granular fertilizer is used as the fertilizer, the fertilizers do not solidify in a lump like the powdered fertilizer.

After the planned fertilizer elution period of the packaged fertilizer 1, for example 100 days, the bag 3 is removed from the surface of the soil 5. By this, the dregs and the like of the coated fertilizer 2 can be easily removed. Further, even if the fertilizer 1 is applied more than necessary, the concentration is not disturbed, and the number of additional fertilizers is greatly reduced, which is suitable for home gardening and the like.

In the above embodiment, the non-woven fabric of synthetic fiber is used as the material of the bag 3, but the material is flexible and water-permeable and has the eyes so that the enclosed granular fertilizer 2 does not spill. Any other known natural fiber or synthetic fiber woven fabric, paper or the like may be used. Furthermore, flexible and porous plastic films can also be used.

Further, in the above-mentioned embodiment, the coated fertilizer 2 having the slow-release property is used to elute over a long period of time. However, the present invention is not limited to this, and it is not limited to this. When the plant 6 having a short period is targeted, the fast-acting fertilizer 2 may be enclosed in the bag 3. Further, in the above embodiment, the bag 3 has a quadrangular shape in plan view, but it may have another shape such as a circular shape, or may not necessarily be flat, and may have a tetrahedral shape. It may be three-dimensional. Even in this case, since the bag 3 is flexible, the lower surface of the bag 3 has the soil 5 placed on it.
There is no problem because it is transformed into a curved surface that engages with the shape of and is adapted to the surface of the soil 5.

As the granular fertilizer, simple fertilizer such as nitrogen, phosphoric acid, potash or the like, or compound fertilizer of two or more component fertilizers, and coated fertilizer thereof are prepared and filled in a bag at an appropriate ratio according to the purpose. You may. In addition, the color of the bag 3 should be the same as that of plants or soil, or the shape of the bag 3 should be the same as the appearance of the leaves, so that the fertilized packaged fertilizer 1 is inconspicuous and the adverse effect on the landscape is suppressed. Alternatively, on the contrary, the color of the bag 3 may be made colorful so as to stand out.

[0027]

As described above, according to the packaged fertilizer of the present invention, a predetermined amount of the required fertilizer is applied without soiling the hands by a simple method of placing it on soil and watering it. The effect that can be obtained is obtained. Moreover,
The fertilizer in the fertilized bag can be stably eluted into the soil over a long period of time.
