SOLUTION: The wall thickness, of the fertilizing package 11 composed of a main part 12 and a lid part 13 both made of a biodegradable resin, is set according to a term between embedded time and fertilization beginning time. The fertilizing package 11 with a prescribed wall thickness in the state filled a prescribed amount of a fertilizer 14 and hermetically sealed is embedded in soil in a fertilizing objective area.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer package and a fertilizer application method, and more particularly, to a fertilizer package and a fertilizer method capable of controlling the timing of fertilization.

[0002]

2. Description of the Related Art In order to grow various plants, various fertilizers are applied according to the growing stage. For example, according to the sprouting stage, flowering stage, fruiting stage, etc. The prescribed fertilizer is given. However, on mountainous slopes, fertilization by mechanical power is difficult, and it depends heavily on human power, which places a heavy burden on fruit farmers and the like.

[0003] Therefore, an object of the present invention is to provide a fertilizer package capable of applying a predetermined fertilizer at a predetermined time and reducing fertilizer work, and a fertilizer method using the fertilizer package. And

[0004]

In order to achieve the above object, the present invention provides a fertilizer package comprising a fertilizer packaged in a biodegradable resin and buried in soil. It is characterized in that the thickness of the biodegradable resin is set according to the period from when the package for use is buried in the soil until fertilization is performed.

[0005] The fertilization method of the present invention is a method of performing fertilization using the package for fertilization, wherein a plurality of biodegradable resins having different wall thicknesses are placed in soil in a fertilization target area. The present invention is characterized in that a predetermined fertilizer is wrapped and buried in a fertilizer application package.

[0006]

FIG. 1 is a sectional view showing an embodiment of a package for fertilizer application according to the present invention, and FIG. 2 is an explanatory diagram showing an example of use of the package for fertilizer application. The fertilizer application package 11 has a main body 12 in which a film or sheet made of a biodegradable resin is formed into a container shape, and a lid 13 that seals an opening of the main body 12. The fertilizer application package 11 is filled with a predetermined fertilizer 14 in a main body 12 and buried in the ground while being sealed with a lid 13 by bonding or the like.

[0007] The biodegradable resin is generally a polymer material which has the same function as conventional resins and is decomposed into carbon dioxide and water by microorganisms existing in nature. Many products are manufactured and sold in consideration of disposal after use, and are used in various fields. Also,
Even in the fields of agriculture and forestry, it does not adversely affect the soil, is not soluble in water unlike paper, and does not require collection and disposal after use. Widely used.

Various materials have been developed for the biodegradable resin. For example, polyester-based, polyamide-based,
Polysaccharides, PVAs, natural polymers such as starch, and the like are known. In the present invention, for example, an aliphatic polyester-based biodegradable resin containing poly-3-hydroxybutyric acid (PHB) ( Biodegradable products obtained by condensation polymerization using polyols such as 1,4-butanediol and aliphatic dicarboxylic acids such as succinic acid and adipic acid as the main raw materials; It is possible to use any biodegradable resin, including resin (manufactured by Showa Kobunshi Co., Ltd .: Bionole).
It can be appropriately selected according to conditions such as the properties and amount of the fertilizer 14 to be filled.

[0009] In the fertilizer application package 11 of the present invention, the main body 12
In addition, the thickness of the biodegradable resin film or sheet of the lid 13 is set according to a period until the fertilization is performed after the cover is buried in the soil. For example, in a certain biodegradable resin, when the decomposition rate in soil in the fertilization target area is about 6 months per 1 mm in thickness, and when it is desired to perform fertilization after three months, the thickness of the biodegradable resin is 0.5 mm and 1.5 mm after 9 months.

As described above, by setting the thickness of the biodegradable resin film or sheet forming the fertilizer application package 11 according to the period from embedding in the soil until fertilization, the desired thickness can be obtained. Predetermined fertilization can be performed sequentially at a time.

Therefore, as shown in FIG. 2, a plurality of fertilizer packages 11 each formed of a biodegradable resin having a predetermined thickness corresponding to a period until fertilization and filled with a predetermined fertilizer 14 are provided. The biodegradable resin is sequentially decomposed from the fertilizer wrapping body 11 having a small thickness of the biodegradable resin by burying the fertilizer in the soil in the fertilization target area 21 at appropriate intervals. Is dissolved in the surrounding soil and given to the trees 22 and the like. Thereby, it is possible to greatly reduce fertilization work on an inclined land or the like where fertilization is difficult.

Although the shape of the fertilizer application package 11 is arbitrary, as shown in FIG. 1, by forming the tip into a pile shape with a sharpened tip, it is easy to bury the soil in the soil. be able to. Furthermore, the entire thickness of the fertilizer package 11 may be a predetermined thickness, but the fertilizer package 11 may be formed by setting a part to a predetermined thickness and forming the other part to be thick. Can be improved, and can be prevented from being deformed or damaged during transportation or burying. In addition, by forming the fertilizer application package 11 as described above using a plurality of biodegradable resins having different decomposition rates in soil, it is possible to use the fertilizer application package for short-term use and long-term use.

[0013]

As described above, according to the present invention,
The fertilizer can be applied at a desired time only by burying it in the soil, and the fertilizing work can be greatly reduced.
