Abstract

The invention discloses controlled-released pesticide fertilizer and preparing method thereof. The controlled-released pesticide fertilizer comprises, by mass, 0.001-15% of effective component A, 4%-45% of nitrogen, 1%-15% of phosphorus, 1%-25% of potassium, 0.1%-5% of microelement, 0.01%-10% of coagulator, 0.01%-10% of binder, 0.15-10% of surfactant and the balance packing. The preparing method of the controlled-released pesticide fertilizer comprises is simple and comprises the steps of preparing of liquid materials, preparing of powder materials and fluidized bed granulating. The controlled-released pesticide fertilizer can control the occurrence of damage caused by diseases, insect pests and weeds can be controlled in all the seasons of crop growth and meet the supply of nutrient substances needed in all the seasons of crop growth, production and use are safe, labor and cost are reduced, and the application amount and the use frequency of pesticides and the fertilizer in the period of crop growth can be reduced.

Description

technical field [0001] The invention belongs to the technical field of medicinal fertilizers, and in particular relates to a controlled-release medicinal fertilizer.

Problems solved by technology

The preparation method of the controlled-release granule fertilizer published in the above-mentioned patent is prepared by pesticide granules, then wrapped layer by layer, and finally dried and sieved to obtain the controlled-release granule fertilizer.

The inventor of this patent has proved through experiments that the controlled-release granule medicinal fertilizer obtained according to the above-mentioned patent is mixed, pulverized, and granulated with the same amount of all ingredients used in its preparation, and the medicinal fertilizer granule obtained by judging from the results of the drug effect and fertilizer effect test has no significant difference , but they all showed significant ability to control release. However, in the later stage of crop growth, they showed poor efficacy and insufficient fertility, and they had to be re-applied to control diseases, insect pests, weeds and topdressing to provide nutritional requirements.
