在我国,利用航空超低容量喷雾防治草原蝗虫,年防治面积已达数百万亩。但是,由于农药制剂尚未定型,溶剂来源困难,以及使用的溶剂腐蚀性强等问题存在,影响了这一技术的推广使用。为解决上述问题,我们于1978、1979连续两年在内蒙昭盟阿鲁科尔沁旗草原,开展了国内首次的航空超低容量喷洒马拉硫磷原油防治土蝗的试验。两年来共试验飞行11架次,飞行15小时37分,处理区面积为69360亩。示范推广64架次,飞行71小时29分,作业面积为494966亩。1980年生产防治面积达
In our country, the use of ultra-low-capacity aerosol spray grassland control locusts, the control area has reached millions of acres. However, due to the fact that pesticide formulations have not been finalized, solvent sources are difficult to be used and the solvents used are corrosive, which has affected the popularization and application of this technology. In order to solve the above problems, we carried out the first trial of ultra-low-capacity spraying of malathion crude oil to control soil locusts in Arukhorqin Banner grassland, Zhaomu, Inner Mongolia for two consecutive years in 1978 and 1979. Over the past two years, a total of 11 flight tests were carried out and 15 hours and 37 minutes were flown. The treatment area was 69,360 mu. Demonstration and promotion of 64 sorties, 71 hours flight 29 minutes, 494966 acres of homework area. 1980 production control area of up to
