木垒县丘陵旱地农区蝗虫危害及措施建议

The Harm of Locusts and Suggestions on Measures in Hilly and Dry Agricultural Areas of Mulei County

木垒县丘陵农区干旱的自然环境非常适宜蝗虫的种群繁衍,加之不合理的耕作,易诱发蝗虫灾害。根据蝗虫危害情况,采用无人机喷洒0.8%的植物源农药阿维印楝素应急防治,效果达86%以上。分析认为,植保无人机是实现规模化喷药治蝗的重要方向,但要长期治理农区丘陵山旱地蝗虫灾害,除应对干旱的气候条件外,还要制止乱垦荒的现象,落实好耕地和草地保护制度,从根本上消除“年年防治、年年有灾”的不良局面。

The arid natural environment in the hilly agricultural area of Mulei County was very suitable for the population reproduction of locusts.In addition,unreasonable farming has induced the occurrence of locust disasters.According to the locust damage situation,the UAV was used to spray 0.8%of the botanical pesticide avidin azadirachtin for emergency control,with an effect of more than 86%.According to the analysis,the plant protection UAV was an important direction to achieve large-scale pesticide spraying and locust control.However,in order to control the occurrence of locust disasters in the hilly and dry land of agricultural areas for a long time,in addition to dealing with the dry climate conditions,should also stop the phenomenon of wasteland reclamation,implement the farmland and grassland protection system,and fundamentally eliminate the bad situation of“annual prevention and control,annual disasters”.
