Abstract

The invention discloses a herbicide-fertilizer for a direct-seeding rice field. The herbicide-fertilizer contains herbicide-fertilizer mixture which is prepared by using bensulfuron-methyl with weeding activity, pretilachlor herbicide and a nitrogen-containing fertilizer, wherein the weight ratio of the bensulfuron-methyl to the pretilachlor is 1:9 and the nitrogen-containing fertilizer consists of urea and ammonium sulfate with weight ratio being 1:2. The invention additionally discloses a production method of the herbicide-fertilizer. Water is used as solvent. A spray-coating method is used for preparing herbicide-fertilizer particle mixture. The process flow is short, the quality is stable and the yield is high. The prepared herbicide-fertilizer is suitable for direct-seeding rice fields, can realize synchronous fertilization and weeding, has the characteristics of high safety, excellent stability and good efficacy, and can achieve the goal of labor saving and time saving.

Description

technical field [0001] The invention relates to a pesticide and herbicide fertilizer, in particular to a pesticide and herbicide fertilizer for rice direct seeding fields and a production method thereof. Background technique [0002] In traditional agricultural production, the application of pesticides and the application of fertilizers in the crop cultivation mode are mostly operated separately, which is time-consuming and laborious, and is not compatible with the development of modern high-efficiency agriculture. Especially in the recent stage, my country is accelerating urbanization and urbanization, and after a large number of rural population and rural labor force have transferred to cities, the shortage of agricultural labor in many places has become serious; With the development of globalization, it is facing the situation of shortage of labor resources. Therefore, modern high-efficiency agricultural production requires multi-functional "medicinal fertilizer" products...
