Problems solved by technology

[0003] According to the release characteristics of pesticides and fertilizer active ingredients, they are divided into free-release conventional type and controlled-release type; the effective rate of conventional pesticides is 20-30%; it is a waste economically and causes environmental pollution
At the same time, the process of preparing fertilizers by the high-tower method is becoming more and more mature, but there is no mature technology for preparing medicinal fertilizers by using the high-tower process. Two problems must be solved: the high temperature in the molten fertilizer stage does not affect the activity of the pesticide, and the contact between the pesticide and the fertilizer does not occur. reaction

Abstract

The invention relates to the technical field of pesticide fertilizer production, and particularly relates to a slow-release high-tower pesticide fertilizer and a preparation method thereof. Aiming atthe problems existing in the production of the pesticide fertilizer by a high tower method at the present stage, the invention provides the slow-release high-tower pesticide fertilizer, and the slow-release effect is guaranteed through double slow release guarantee of a pesticide and a chemical fertilizer; the activity of the pesticide is ensured by adding carrier powder; and under the action of anitrification inhibitor or a urease inhibitor, the effective utilization rate of the chemical fertilizer is realized, and the growth requirements of crops are met. In addition, the invention also provides a preparation method of the slow-release high-tower pesticide fertilizer. The method is simple and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of medicinal fertilizer production, in particular to a slow-release high tower medicinal fertilizer and a preparation method thereof. Background technique [0002] The broad definition of pesticides refers to chemicals used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, and to regulate, control and affect the metabolism, growth, development and reproduction of plants and harmful organisms. A substance or a mixture of several substances and its preparations that are synthesized or derived from organisms, other natural products and applied biotechnology. In a narrow sense, it refers to a class of drugs used to kill insects, bacteria, and harmful animals (or weeds) to ensure and promote the growth of plants and crops in agricultural production. Fertilizer is to provide the necessary nutritional requirements for crop growth. Theref...
