摘  要:
通过田间试验研究植保无人机航空喷施和电动喷雾器人工喷施9.5%丙嗪嘧磺隆悬浮剂(SC)与20%氰氟草酯可分散油悬浮剂(OD)桶混剂对机插秧水稻的安全性和杂草的防效。结果表明,机插秧水稻移栽后12 d,植保无人机航空喷施或电动喷雾器人工喷施9.5%丙嗪嘧磺隆SC 55 mL/667 m~2与20%氰氟草酯OD 75 mL/667 m~2桶混剂对机插秧稻田稗属杂草、千金子、鸭舌草、多花水苋的株防效和鲜重防效均达95%以上,且对水稻安全。植保无人机航空喷施或电动喷雾器人工喷施9.5%丙嗪嘧磺隆SC与20%氰氟草酯OD桶混剂,1次施药有效控制了机插秧水稻全生育期草害,对水稻安全,省工节本。

摘  要:
A field experiment was conducted to study the efficacy of propyrisulfuron 9.5% SC mixed with cyhalofop-butyl 20% OD for weed control and its selectivity to mechanically-transplanted rice. At 12 days after transplanting, efficacy the herbicide mixture at 75 mL/667 m~2 sprayed by unmanned aerial vehicle(UAV) or knapsack electric sprayer based on plant and fresh weight of key weeds(Echinochloa spp.,Leptochloa chinensis(L.) Nees.,Ammannia multiflora,Monochoria vaginalis(Burm. f.) Presl.,Cyperus difformis L.,Eclipta prostrata(L.) L.,Ludwigia prostrate Roxb.,and Cyperus iria L.) was above 95%. The mixture was selective to rice. Therefore, the mixture sprayed once by UVA or knapsack electric sprayer could control weed damage effectively and selectively during whole growth period of rice,saving labor and costs.
