为了研究TH80-1型植保无人机对水稻中后期主要病虫害稻飞虱、稻纵卷叶螟和水稻纹枯病的防治效果及应用前景,进行了植保无人机低空低容量喷雾和人工电动喷雾器大容量喷雾两种不同施药方式田间药效试验。结果表明,在水稻分蘖后期,在相同的药剂配方条件下,TH80-1型植保无人机施药后3、7、14 d,对稻飞虱的防治效果为70.83%、81.23%、91.04%,对稻纵卷叶螟的保叶效果为66.76%、69.32%、87.33%;施药后7、14 d对水稻纹枯病的防治效果为76.62%、91.22%,该施药方式对水稻中后期主要病虫害防治效果显著,并且均优于传统人工喷雾器喷洒防治效果。

In order to study the efficacy and application prospect of TH80-1 plant protection UAV in controlling main disease and insect pests, such as planthopper, Cnaphalocrocis medinalis and Pellicularia sasakii of rice at the middle and late stage, a field experiment was conducted with two different spraying methods, low flying plant protection UAV spraying at a small volume and power sprayers spraying at a large volume by manual work. The results showed that with the same reagent combination at rice late tillering stage, the control efficacy in 3, 7 and 14 d after TH80-1 UAV spraying pesticides were...
