Abstract

The invention belongs to the technical field of pesticides and chemical fertilizer, and particularly relates to multi-effect slow/controlled-release pesticide-added fertilizer as well as a preparation method and an application thereof. The pesticide-added fertilizer adopts chemical fertilizer granules as a core, the core is coated with a first controlled-release membrane, the controlled-release membrane is coated with a pesticide layer, and the pesticide layer is coated with a second controlled-release membrane. A pyrrolecarbonitrile compound is blended with a chloronicotinyl insecticide and a triazole fungicide, multi-effect slow/controlled-release pesticide-added fertilizer granules are prepared from the fertilizer as the core under the action of thermoplastic acrylic resin controlled-release membranes and a sodium carboxymethyl cellulose binder, and content of effective ingredients and thickness of the controlled-release membranes are determined by growth period of crops and growing environments such as paddy field or dry land; in the whole growing period of the crops, the pesticide-added fertilizer is applied once, other insecticides, fungicides and fertilizer are not needed, so that the purposes of saving manpower, reducing waste of the chemical fertilizer and pesticides and environmental pollution and the like are achieved, and realization of zero growth of the application amount of the chemical fertilizer and pesticides in China can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of pesticides and fertilizers, and in particular relates to a multifunctional slow-controlled release medicinal fertilizer and its preparation method and application. Background technique [0002] my country has proposed to achieve the strategic goal of zero growth in the use of pesticides and fertilizers under the premise of ensuring the level of total grain production by 2020. With the reduction of the working population engaged in agricultural production in rural areas of our country, the multiple cropping index of crops has been relatively reduced, and the urbanization process has brought about the shrinking of cultivated land. To maintain the current level of my country's total grain production, it is necessary to increase the output of crops per unit area. . The traditional way to increase the yield per unit area of ​​crops is to increase the use of pesticides and fertilizers per unit area, but this ap...
