过去多采用常量喷雾法喷洒水溶性杀菌剂。本试验采用低量弥雾法喷洒水溶性氟硅脲杀菌剂防治小麦条锈病,药效好,工效高,很适合小麦后期用药的要求,小麦千粒重和亩产量明显增加,经济效益显著。10%氟硅脲膏剂最适剂量是1斤/亩,37%氟硅脲晶粉是0.3斤/亩,最适喷液量是5～10斤/亩。根据试验所拟定的技术操作规程,经两年大面积试用,证明是可行的。试验表明,低量喷施水溶性杀菌剂后,了解掌握雾滴在后期小麦田株冠层中的运动分布规律对科学用药具有指导意义。
In the past, the use of constant spray spray water-soluble fungicides. In this experiment, the spray-spraying of water-soluble flufenocarb fungicides to control stripe rust of wheat was conducted in this experiment. It has good efficacy and high efficiency. It is very suitable for the requirements of late-stage wheat. Wheat 1000-grain weight and yield per acre increased obviously with obvious economic benefits. The optimum dose of 10% fluosilicate paste is 1 kg / mu, 37% fluosilicone crystal powder is 0.3 kg / mu, and the optimum dosage is 5 ~ 10 kg / mu. According to the test of the technical operation of the rules, after two years of large area trial proved to be feasible. Experiments show that spraying a small amount of water-soluble bactericides, the understanding of the droplet in the late wheat field canopy movement distribution of the guidance of scientific medication.
