る。Detailed Description of the Invention (Field of Industrial Application) The present invention covers the surface of coated granular fertilizers with various slow-release degrees with a mixture of various agrochemical materials and ethyl cellulose, and provides a variety of functions centered on fertilizer effects. The present invention relates to a multi-coated granular fertilizer that can be applied to a wide range of plant cultivation fields by making it easier to use.

能な肥料が要望されている。これらに答えて被覆粒状肥
料が注目され、利用されている。In recent years, due to advances in agricultural technology, there has been a demand for fertilizers that are less likely to cause concentration disturbances, have less runoff, and can supply nutrients that meet the needs of plants. In response to these problems, coated granular fertilizers are attracting attention and being used.

い方が行われている。Regarding fertilizers, coated granular fertilizers include those containing three or more elements, two elements, or a single element depending on the purpose of use, but in order to meet the needs of plants, it is necessary to blend or coat two or more types of coated granular fertilizers. It is used depending on the purpose, such as blending granular fertilizer with uncoated granular fertilizer.

し好ましくない。(Problems to be Solved by the Invention) When using coated granular fertilizers in a blended manner, it is difficult to maintain the uniformity of each component due to the complexity of the blending operation, transportation, and separation of fertilizer particles during fertilization. It is not preferable to coat granular fertilizers that contain all the elements required by fertilizers, as this may cause insolubilization due to chemical changes during the production and leaching process after application.
被覆粒状肥料をベースに肥料とブレンドする場合あるい
は被覆用原肥に共存させる場合にも前述したと同じ問題
点が指摘される。特に有機物質の場合は安全性の面から
問題が多い。The same problem as mentioned above is also pointed out when blending a coated granular fertilizer with a fertilizer or when making it coexist with a raw fertilizer for coating. Especially when using organic substances, there are many problems from the viewpoint of safety.
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

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 carried out 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 fast-release or slow-release fertilizer in an arbitrary ratio. , proposes a granulated granular fertilizer. However, when covering the surface of the coated granular fertilizer with fertilizer as in this case, a drying process must be provided to use moisture, which complicates the process and causes deterioration due to heating.

。Furthermore, 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 in the outer membrane cause deterioration of the outer membrane, and the fertilizer components in the outer membrane are eluted. materials used. This is related to the deterioration of not only the outer layer membrane but also the inner layer membrane during the storage period, and it is not uncommon for fertilizer components in the outer layer membrane to deteriorate.
Affects the acceleration of component elution of the core coated fertilizer.

昭６１−１２５６３号公報において、被覆粒状肥料の表

生ずる。Furthermore, in the above-mentioned Japanese Patent Publication No. 59-306801 and Japanese Patent Application Laid-open No. 61-12563, the fertilizer components coated on the surface of the coated granular fertilizer are quickly separated from the fertilizer, and the There is a difference in the rate of fertilizer effectiveness compared to the ingredients.
従って、被覆粒状肥料をベースに、その表面に農業資材
を被覆した多重被覆粒状肥料が望まれている。Therefore, a multi-coated granular fertilizer is desired, which is based on a coated granular fertilizer and whose surface is coated with an agricultural material.
〔問題を解決するための手段）

する製膜剤について検討した。[Means for Solving the Problem] The present inventors have found that it is possible to coat the surface of the coated granular fertilizer with agricultural materials using the same manufacturing method as for the core coated granular fertilizer, and to prevent the elution of the coated granular fertilizer from occurring. We investigated a film-forming agent that has almost no effect on fertilizers, and that the effectiveness of agricultural materials in the coated outer layer is not affected by external environmental factors, making it possible to maintain fertilizer effects.
その結果、製膜剤として、エチルセルロースを用い、塩
素化炭化水素の溶解液に農業資材の微粉体を分散させな
がら、核となる被覆粒状肥料の表面を被覆することで本
発明を完成した。As a result, the present invention was completed by using ethyl cellulose as a film-forming agent and coating the surface of the core coated granular fertilizer while dispersing fine powder of agricultural materials in a solution of chlorinated hydrocarbon.
即ち、本発明は被覆粒状肥料をエチルセルロースと農業
資材の混合物で被覆してなる多重被覆粒状肥料である。That is, the present invention is a multi-coated granular fertilizer obtained by coating a coated granular fertilizer with a mixture of ethyl cellulose and agricultural materials.

ことが考えられる。Agricultural materials in the present invention include fertilizers, soil conditioners,
Examples include agricultural chemicals and plant growth regulators. The target fertilizers are those that become insolubilized and difficult to elute due to chemical reactions when they coexist in coated granular fertilizers. For example, there are minerals, lime, and trace components that easily react with phosphoric acid. or,
It is possible to coat the surface with nitrogen, phosphoric acid, or phosphoric acid, which elutes slowly during processing.

Furthermore, agricultural chemicals include herbicides as culture medium treatment agents, penetrating release agents, nematicides, fungicides for soil diseases, and the like. Furthermore, plant growth regulators include oxygen generators, stimulants, quality improvers, and the like.

As in Example 1, a 1.5% perchloroethylene solution containing 2.9 kg of ethyl cellulose and 11.5 kg of fine powder of nitrofumic acid was applied to the solution containing 10% of humic substances. Got the product. As a result of examining the component elution of the product and the coated granular fertilizer used as cores, there was no significant difference in nitrogen, phosphoric acid, and potassium between the two. In addition, in the case of the product, the initial elution tended to be suppressed, albeit slightly, which was a favorable result.
