Herbicide-containing fertilizer and preparation method and use thereof

Abstract

The invention provides a herbicide-containing fertilizer and a preparation method and use thereof. The herbicide-containing fertilizer, based on 100 percent of total mass, consists of the following formula components in percentage by weight: 15 to 40 percent of glyphosate, 0.4 to 8 percent of trace element compound, 5 to 15 percent of surfactant, 0.5 to 20 percent of stabilizer and the balance of filler. In the herbicide-containing fertilizer provided by the embodiment of the invention, because the glyphosate, trace element component and the like are mixed reasonably, the soil fertility, resistance in crops (particularly glyphosate resistant transgenic corps) and crop yield are all increased, and the crop yield is improved by up to 30 percent; and the herbicide effectively lowers the labor intensity and manual cost of agricultural production. In addition, the herbicide-containing fertilizer is produced by mixing by group or mixing by crushing, so the dispersion uniformity of the components is improved effectively, the preparation method is simple in process and low in energy consumption and the production cost is lowered; and the method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a herbicide 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 and fert...

Problems solved by technology

Don Iluber and G.S. Johal, who recently retired from Purdue University in the United States, pointed out that the widespread use of glyphosate in the United States can "significantly increase the severity of various plant diseases, impair the plant's defense system against pathogens and diseases, and fix soil and plant nutrients. They cannot be used by plants"

Glyphosate weakens plant resistance, making it vulnerable to soil-borne fungal pathogens, Huber study finds

[0005] So far, there is no research report on the addition of trace elements to glyphosate preparations to overcome the negative effects of glyphosate on crops and to improve resistance and increase yield of transgenic crops
