Problems solved by technology

However, most of the existing coating technologies use the physical effect of the coating to achieve sustained release, which is not friendly to the soil environment, and a large amount of use will destroy the ecological balance of the soil; and the thixotropy of the coating is poor, and the coating is easy to fall off during transportation and sowing. Irrigation or heavy rain and wind can damage its structure and affect its function

Abstract

The invention discloses a crop coating pesticide fertilizer. The crop coating pesticide fertilizer is prepared from the following raw materials: spirotetramat, chlorantraniliprole, pyraclostrobin, prothioconazole, urea, monopotassium phosphate, a trace element growth regulator, activated soil, a flocculating agent and an adhesive. The preparation method comprises the following steps of (1) weighing the raw materials, (2) mixing and stirring spirotetramat, chlorantraniliprole, pyraclostrobin and prothioconazole to obtain a material A, (3) adding water into the material A, urea, monopotassium phosphate and a trace element growth regulator, mixing, stirring, granulating and drying to obtain a material B, and (4) adding water into the activated soil, the flocculating agent and the adhesive, mixing, stirring, adding into a coating machine, spraying, and coating the material B to obtain the product. The slow release time of the pesticide and the fertilizer can be prolonged, the release speedof the chemical fertilizer conforms to the absorption speed of crops, the utilization rate of the pesticide and the fertilizer is greatly increased, and the dosage of the pesticide and the fertilizeris reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a crop-coated medicinal fertilizer and a preparation method thereof. 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 a certain process technology. Generally, fertilizers are used as the carrier of pesticides. For the sustainable development of contemporary agriculture, medicinal fertilizer is a new attempt for modern agriculture supported and driven by powerful technology. Medicinal fertilizer can combine two operation steps in the field into one, which not only saves labor, but also reduces time and energy consumption. [0003] At present, although the medicinal fertilizer products on the market effectively combine pesticides and fertilizers, they also have ob...
