应用科学的施药技术,可以省药、省工,提高防治效果。据报道,江苏省高效节本施药技术应用研究协作组,通过田间试验与示范结果表明,应用高速旋水片喷雾,能改善雾化性能和雾粒的沉积性,提高农药的利用率和防治效果。据试验,在达到同样防治效果的情况下,采用高速旋水片喷雾的用药量与常规喷雾法相比,防治小麦赤霉病、棉红铃虫、稻蓟马可减少用药量14—20％;防治小麦白
Application of science and technology application, you can save medicine, labor, improve control effect. It has been reported that Jiangsu Province, efficient and cost-effective application of pesticide technology research collaboration group, field trials and demonstration results show that the application of high-speed rotary spray tablets can improve the fogging performance and fog deposition, improve pesticide utilization and control effect. According to the test, in the case of achieving the same control effect, the dosage of spraying with high-speed rotary blade can reduce the dosage of 14-20% compared with the conventional spraying method, preventing and curing wheat scab, cotton bollworm and rice thrips; Control wheat white
