肥料に関する。Detailed Description of the Invention (Industrial Application Field) The present invention covers the surface of granular fertilizer with a mixture of agricultural materials and film-forming material, and then further covers it with a film material to form a core. The present invention relates to a granular fertilizer coated with agricultural materials, which has the effects of the agricultural materials coated on the surface of the granular fertilizer in addition to the effects of the granular fertilizer, and has doubled functionality and is applicable to a wide range of plant cultivation fields.
（従来の技術）
近年、農業技術の進歩から、濃度障害を起こしにくい肥

肥料、とりわけ、植物の要求に適った養分供給が可能な
肥料が注目され、種々の肥料が提案され、一部は実用に
供されている。(Conventional technology) In recent years, advances in agricultural technology have led to the development of fertilizers that are less likely to cause concentration problems, fertilizers that have less runoff, fertilizers that can be applied less frequently and save labor, and especially fertilizers that can supply nutrients that meet the needs of plants. This has attracted attention, and various fertilizers have been proposed, some of which are now in practical use.
また、植物の健全な栽培管理においては、植物の要求に
応じた養分をバランスよく供給できる肥料が望ましいこ
とは勿論のことであるが、植物の生存環境である培地を
健全に保持するための培地改良剤や、培地の殺菌、殺虫
剤、さらには競合植物としての雑草の抑制、防除のため

が要求されている。In addition, for the healthy cultivation and management of plants, it goes without saying that it is desirable to use fertilizers that can supply nutrients in a well-balanced manner according to the needs of the plants. There are demands for improving agents, sterilizing culture media, insecticides, herbicides for controlling and controlling weeds as competing plants, and plant growth regulators that can regulate plant growth.
これらの農業資材は、植物の栽培期間中、あるいは栽培
期間に前後して施用されるものであり、施用時期、場所
など共通する面も多い。These agricultural materials are applied during or around the cultivation period of plants, and they have many things in common, such as the timing and location of application.
そこで、作業の省力の面から、農薬肥料のように肥料と

試みられている。Therefore, in order to save labor, attempts have been made to apply products such as agrochemical fertilizers by mixing fertilizers and pesticides, blending granular products of each, and applying them in liquid form.

ている。In addition, looking at fertilizers alone, there are blends of coated granular fertilizers with various slow-release degrees, blends of coated granular fertilizers and uncoated granular fertilizers, and slow-release fertilizers that include coated granular fertilizers as the core. It has been proposed to apply granular fertilizer by wrapping the surrounding area with immediate-release or slow-release fertilizer and granulating it.

There is a need for an application method that can save labor, ensure safe handling, and reduce environmental pollution.
２種以上の農業資材の組合わせについては、前述したよ
うに異種肥料のブレンドや農薬と肥料を混合して製品化
したものなどが試みられている。As for combinations of two or more types of agricultural materials, attempts have been made to create products by blending different types of fertilizers and mixing pesticides and fertilizers, as described above.
しかしながら、ブレンドの場合、操作の繁雑さや輸送、
施用時における粒分離など、成分の均一性保持が難しい
こと、また、肥料と農薬の混合では、化学反応による効
率低下を引き起こすことがあり、限られた資材での組み
合わせしかできないのが現状である。However, in the case of blending, the complexity of operation, transportation,
It is difficult to maintain uniformity of ingredients due to grain separation during application, and mixing fertilizers and pesticides can cause a decrease in efficiency due to chemical reactions, so currently only a limited number of combinations can be made. .
このような問題を解決する方向での検討も行われており

肥料で包み、造粒した粒状肥料を提案している。しかし
、この粒状肥料においては、被覆粒状肥料の表面を肥料
で覆う際に水分を使うため、乾燥工程を設けなければな
らず、工程の複雑さと共に加熱による変質が生ずる。Studies have been conducted to solve these problems. For example, in Japanese Patent Publication No. 59-30680, a coated granular fertilizer is used as a core, and the surrounding area is wrapped with an arbitrary ratio of quick-release or slow-release fertilizer. We suggest granular fertilizer. However, in this granular fertilizer, since moisture is used when covering the surface of the coated granular fertilizer with fertilizer, a drying process must be provided, which complicates the process and causes deterioration due to heating.

影響する。Further, Japanese Patent Application Laid-Open No. 125631/1983 teaches a method of coating the surface of a coated fertilizer made of a thermosetting resin with a fertilizer containing a pH adjuster. In this method, the fertilizer and pH adjuster placed inside the outer membrane cause deterioration of the outer membrane and remove the fertilizer components inside the outer membrane. The outer membrane is made of the same material as the inner membrane. This is related to the deterioration of not only the outer layer membrane but also the inner layer membrane during the storage period, and affects the acceleration of the elution of not only the fertilizer components in the outer layer membrane but also the components of the core coated fertilizer.
さらに、前述した特公昭５９−３０６８０号、特開昭６

In No. 1-125631, the fertilizer components coated on the surface of the coated granular fertilizer are all quickly separated from the fertilizer, resulting in a large difference in the rate of fertilizer effectiveness compared to the components in the fertilizer.

It is possible within the range of The higher the proportion of film-forming material, the more
Although the adhesion of agricultural materials increases, including the subsequent coating process,
The ratio is preferably in the range of 50:50 to 20:80 because there is a risk that the rate of component elution from the product fertilizer will be abnormally delayed, and if the ratio of the film-forming material is reduced, the adhesion of agricultural materials will be reduced.
