本発明は鉢物、園芸等に用いられる土壌に最適であって
良好な施肥効果を有するとともに、土壌の改良にとって
も有益な園芸用肥料に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a horticultural fertilizer that is optimal for soil used for potted plants, gardening, etc., has a good fertilizing effect, and is also useful for soil improvement. It is.
一般に肥料は粒状又は粉末状でありこれを土壌中に施肥

小さな面積の土壌にとっては従来の肥料では肥料成分の
水溶度が大きく速効性のため施肥効果が過度となり植物
に害を与え、時には肥料の有効成分が溶脱し易いととも
に、鉢物等の施肥作業ではその取り扱いの簡便さにも欠
けるものであった。Generally, fertilizers are in the form of granules or powders, and it is well known that fertilizers are applied to soil and watered to provide nutrients to plants. This fertilizer is suitable for fertilizing the soil of vast arable land in agriculture, but for small areas of soil such as potted plants and gardening, conventional fertilizers have a high water solubility and are fast-acting, making them ineffective. Excessive amounts of fertilizers harm plants, sometimes the active ingredients of fertilizers tend to leach out, and they are not easy to handle when fertilizing potted plants.
そこで、従来このような問題点に鑑みて、鉢物栽培に適

分が先に水溶し、水溶し難い部分が肥料中に残りこの部

に供給出来ない欠点があった。In view of these problems, in the past, water was added to the fertilizer components in order to either slow down the fertilization effect on the soil to provide an appropriate fertilizing effect, or to provide a long-term fertilizing effect, making it suitable for pot cultivation. Coated with films of varying solubility and thickness,
Alternatively, it is known that a fertilizer component is mixed with a water-insoluble synthetic resin and the mixture is solidified and molded into a rod shape. While these fertilizers have the advantage of being convenient to use and handle, and being able to determine the amount of fertilizer consumed, the easily water-soluble parts of the fertilizer components dissolve in water first, and the less water-soluble parts dissolve in the fertilizer. Since this remaining portion is leached out later, there is a drawback that fertilizer components cannot be supplied to the soil in a well-balanced manner.
更に、肥料成分に非水溶性の合成樹脂を混練して固化成

ける手間が必要であること等の問題点があった。Furthermore, with fertilizers that are made by kneading water-insoluble synthetic resin into fertilizer components and solidifying them, when this is applied to potted plants, even after all of the fertilizer components have been eluted, a hard or spongy insoluble form may appear in the pot. There are problems such as the unsightly appearance of the insoluble matter left behind and the need for time and effort to clean up the insoluble matter after the fertilizer components have been eluted into the soil.

も育苗な肥料を提供することを目的とするものである。[Means and effects for solving the problems] In consideration of the above-mentioned problems, the present invention adds a plasticizer to the fertilizer component and one type of thermoplastic resin such as water-soluble polyvinyl alcohol, or a mixture thereof. Alternatively, by mixing without adding anything and molding it into the desired shape, all of the fertilizer components are eluted into the soil without leaving any insoluble matter behind, making it ideal for soil used for potted plants, gardening, etc. The purpose of this invention is to provide a fertilizer that has a good fertilizing effect and is also effective for improving soil suitable for plant growth and for raising seedlings.

According to the rod-shaped fertilizer according to the present invention, it can be seen that the fertilizers of all Examples generally exhibit a better dissolution rate than the conventional products. Furthermore, the fertilizer of Example 1 showed the best dissolution rate no matter which soil it was applied to, and especially when it was applied to Akadama soil, one sample after two weeks showed the highest dissolution rate. Furthermore, the fertilizers of all examples were completely dissolved in the soil after 8 weeks (approximately 2 months) without any insoluble matter remaining unlike conventional products, and the remarkable fertilizing effect continued. There was found.

粒子径の団粒構造となった。Furthermore, in the present invention, PVA is added to the fertilizer ingredients and mixed, so this PVA dissolves and flows into the soil by irrigation, and its viscosity causes the soil to aggregate, resulting in aggregates with the optimum particle size for plant growth. It became a structure.

る。Therefore, the sustainability of the soil with this aggregate structure increases air permeability, water permeability, and water retention capacity, and promotes rapid plant growth and germination. Therefore, the soil modified by the fertilizer according to the present invention containing PVA is extremely effective for greenhouse cultivation and horticulture, where water supply and drying can be easily controlled. In addition, since the fertilizer is molded using a thermoplastic resin such as PVA as a base, it is easy to mold it into a desired shape that is optimal for use as fertilizer for potted plants, gardening, and the like.

料を容易に成型することが出来る効果がある。As described above, the present invention comprises a fertilizer component and a water-soluble thermoplastic resin or a mixture thereof, which is mixed with or without the addition of a plasticizer and molded into a desired shape. Since it is mixed with a thermoplastic resin and molded into the desired shape, all of the fertilizer components are eluted into the soil without leaving any insoluble matter as in the case of conventional methods, and it has a remarkable fertilizing effect on plant growth. It is ideal for soil used for potted plants, gardening, etc. as there is no need to clean up insoluble matter, and in addition, it has P.
The addition of thermoplastic resins such as VA has the effect of improving soil suitable for plant growth, making it possible to provide fertilizers that are extremely beneficial for plant growth, as well as being able to easily mold fertilizers into shapes suitable for gardening. There is.
