Embodiment Construction

[0050] With reference to the flow chart of the production process of medicinal fertilizer of the present invention. According to the principle of multiple dilution and distribution, high-concentration butachlor powder, bensulfuron-methyl powder, surfactants, and fine particle size fillers are diluted and mixed multiple times to form a premix of a certain concentration; the low-concentration pesticide premix The mixture is mixed with carrier fertilizer, rice safener, and stabilizing agent to form stable medicinal fertilizer granules. Adjust the speed of the exhaust fan to control the inlet and outlet temperatures of the drying cylinder. After actual testing, the inlet temperature is controlled at 140-180°C, and the outlet temperature is controlled at 55-75°C. The drying particle molding rate is improved from the original one-time molding The rate is increased from 50% by weight to 70% by weight; the decomposition rate of the pesticide components of the product can be controlled...

Description

technical field [0001] The invention relates to a rice herbicide fertilizer and a manufacturing method thereof technical background [0002] The research on herbicide fertilizers, the data records were first seen in the 1964 "Research Report on the Agricultural Experimental Field in Northeast Japan". Researchers represented by Koichi Bentani began to study the herbicide pentachlorophenol (PCP) mixed into fertilizers as fertilizers in the early 1960s. Base fertilizer is applied to achieve the purpose of saving labor and continuing the weeding effect. The results of the study showed that the use of NH mixed with PCP in the field 3 - After N fertilizer, it can prevent NO 3 The reason for the disappearance of - is that PCP can inhibit the metabolism of nitrifying bacteria in the soil and hinder nitrification, so that PCP mixed with fertilizers can not only maintain its efficacy, but also inhibit nitrification and similar topdressing effects. In the mid-1960s, American researc...
