Problems solved by technology

[0005] In the published invention patents of medicinal fertilizers, the fertilizer production process is basically used to manufacture medicinal fertilizers. The pesticide components are mixed with fertilizers, and the granulation is carried out by means of transfer or extrusion. This process will encounter many problems in production and application. Problems, such as products with low content of pesticide ingredients (especially herbicide content of a few tenths), it is difficult to mix evenly, and it is easy to cause uneven dosage during use, affect the efficacy of the pesticide, and even cause phytotoxicity; the temperature of the drum is too high High temperature (120-250 degrees Celsius) can easily cause the decomposition and gasification of pesticide components; the hardness of extrusion granulation particles is too high, which will affect the release of pesticide components, thereby affecting the efficacy of the pesticide, etc.

Abstract

The invention provides a granular pesticide fertilizer, and a preparation method and application thereof. The granular pesticide fertilizer comprises the following components expressed in mass percent: on the basis that the total mass of the granular pesticide fertilizer is 100%, 0.001 to 20% of a pesticide active component, 70 to 99% of a granular fertilizer carrier, 0.05 to 9% of an organic solvent, 0.05 to 0.5% of a surfactant and 0.05 to 0.5% of a coating agent. According to embodiments in the invention, the pesticide active component and the granular fertilizer carrier in the granular pesticide fertilizer are reasonably combined, which allows the problem of damage by diseases and insects to soil in agricultural production to be effectively overcome and enables soil fertility to be improved and labor and time to be saved. The granular pesticide fertilizer is produced by using a normal temperature spraying adsorption process and a cladding process, so the preparation method for the granular pesticide fertilizer has the advantages of a simple process, low energy consumption, reduction in production cost, easiness in controlling and operating and suitability for industrial production.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a granule medicine fertilizer and its preparation method and application. Background technique [0002] The earliest research on medicinal fertilizers is the research on herbicidal medicinal fertilizers, and the data records were first seen in the 1964 "Research Report on the Agricultural Experimental Field in Northeast Japan". In the early 1960s, researchers represented by Koichi Motoya studied the herbicide pentachlorophenol (PCP) mixed into fertilizer as base fertilizer application, in order to achieve the purpose of saving power and extending the weeding effect. The research results show that the loss of nitrate nitrogen can be prevented after the application of ammonium nitrogen fertilizer mixed with PCP in the field, because PCP can inhibit the metabolism of nitrifying bacteria in the soil and hinder the nitrification, so that the mixed application of PCP a...
