选用四轮喷杆喷雾机、三轮喷杆喷雾机和电动喷雾器分别对麦田蚜虫进行全程化学防除,旨在探索新型药械和配套施药技术。通过测试三种药械的压力流量,确定各药械施药行走速度及作业性能表现。通过后期碾压率、药效、测产调查得出,四轮四轮喷杆喷雾机、三轮喷杆喷雾机和电动喷雾器碾压率分别为6.4‰、8.2‰、0.6‰,其它三种药械施药后3天防效分别为94.6%、91.3%、84.5%。后期测产得出比全县平均产量分别增产16.6%、11.6%和6%,节本增效明显。因此,四轮喷杆喷雾机在防效、作业性能、综合效益上效果最好。
The four-wheel spray sprayer, the three-wheel spray sprayer and the electric sprayer were used to control the aphids in wheat field respectively. The aim was to explore new types of medical equipment and the related application technologies. By testing the pressure flow of three kinds of drug devices to determine the speed of each drug application and operating performance performance. Through the late rolling rate, efficacy, production survey found that the four-wheel four-wheel spray sprayer, three-wheel spray sprayer and electric sprayer were 6.4 ‰, 8.2 ‰, 0.6 ‰, the other three Three days after the drug administration, the preventive effects were 94.6%, 91.3% and 84.5% respectively. The latter part of the measured output increased by 16.6%, 11.6% and 6% respectively over the average output of the county, and the cost-saving effect was obvious. Therefore, the four-wheel spray sprayer in the anti-performance, operational performance, the best overall efficiency.
