摘要：

通过植保无人机、担架式喷雾机2类器械3种药剂配方对水稻直播田杂草防除效果进行比较评价。结果发现，无论采用无人机还是担架式喷雾机进行防治作业，对禾本科和阔叶杂草的防效相当；19%氟酮磺草胺SC（肯收）10 mL/667 m2+10%氰氟草酯EC（千金）150 mL/667 m2、40%氰氟草酯EC（卫稻夫）150 mL/667 m2、10%氰氟草酯EC（千金）150 mL/667 m2 3种药剂处理对千金子的防治效果相近，药后7～40 d株防效和鲜质量防效基本在90%以上，并且对稗草有良好的抑制效果。因此认为，在水稻直播田防除杂草时，可采用植保无人机进行施药。

Abstract:

In order to evaluate the weeds control effects of UAV in direct-seeding rice fields, a filed experiment was carried out using UAV and stretcher sprayer as spraying equipment, and setting three agents treatment. The results showed that the control effects of both UAV and stretcher sprayer on gramineous weeds and broad-leaved weeds were equally 19% fluorosulfon SC（Kensuo） 10 mL/667 m2 add 10% cyhalothrin EC （Qianjin） 150 mL/667 m2, 40% cyhalothrin EC （Weidaofu） 150 mL/667 m2, 10% cyhalothrin EC 150 mL/667 m2 had similar effects on sprangletop, the control effects of quantity effect and fresh weight effect were more than 90% after 7~40 days after treatment, and the control effect on barnyardgrass were also good. Therefore, UAV could be used to control weeds in direct-seeding rice fields.
