Problems solved by technology

Granules maintain the advantages of convenient use and high work efficiency of powders, while overcoming the shortcomings of powders that are easy to drift, pollute the environment, and have low effective utilization.
[0004] However, the release time of this kind of granules is short, and the release space, release time, and release concentration are uncontrollable. Therefore, a granule with sustained release effect is needed, and its release quantity, release time, and release space are controllable, and the medicinal ingredients are used according to The preset concentration and time (made according to the needs of pest control) are continuously and slowly released into the environment, and can maintain a specific concentration for a long time

Abstract

The invention discloses a controlled-release pesticide fertilizer granule containing aryl pyrrole nitrile and methoxyl acrylate. The controlled-release pesticide fertilizer granule containing aryl pyrrole nitrile and methoxyl acrylate takes a chemical fertilizer granule as a core, the core is sequentially coated with a first controlled release film, a first pesticide layer, a second controlled release film, a second pesticide layer, an Nth controlled release film, an Nth pesticide layer and an (N+1) th controlled release film, and N is an integer greater than 0. Compared with the prior art, the controlled-release pesticide fertilizer granule has the advantages that fertilizer and pesticide components are separated through the controlled release films, the problem that the fertilizer and the pesticide are mixed together to interfere with each other is avoided, the controlled release films can control the release of the pesticide and the fertilizer, and the release speed and time of nutrients can be controlled as required, so that the lasting time of the pesticide and the fertilizer is long.

Description

Technical field [0001] The invention relates to the technical field of pesticides and fertilizers, and specifically refers to a controlled-release pharmaceutical fertilizer granule containing arylpyrrolonitrile and methoxyacrylate. Background technique [0002] Medicinal fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a certain proportion and stabilizing the fertilizers and pesticides in a specific compound system through certain processes and technologies. Fertilizer is generally used as the carrier of pesticides. Medicinal fertilizer has the active ingredients of both pesticides and fertilizers. Once applied, it can not only meet the needs of crops for nitrogen, phosphorus, and potassium fertilizers, but also kill pests that harm plants. At the same time, it has the effect of preventing and controlling crop diseases. In this way In the future, the two operation steps in the field can be combined into one, which not ...
