摘要
于2016、2017年分别在江西省泰和县和南昌县进行了应用植保无人机超低容量喷施技术防治水稻纹枯病的田间试验。试验结果表明:植保无人机超低容量喷施对水稻纹枯病的防治效果与用药液量呈正相关;在泰和县试验点,在统一施用25%氟环唑悬浮剂420 g/hm^2的条件下,无人机用药液15.0 L/hm^2的防效(84.20%)显著高于人工电动喷雾药液450.0 L/hm^2的防效(81.83%);在南昌县试验点,在统一施用40%咪铜·氟环唑悬浮剂375 g/hm^2的条件下,无人机用药液7.5~15.0 L/hm^2的防效为53.73%~69.44%,显著低于人工电动喷雾药液450.0 L/hm^2的防效(86.72%)。
Field trials in Taihe county and Nanchang county of Jiangxi province during 2016 ~ 2017 were carried out to evaluate the efficiency of applying ultra-low-capacity spraying technology by plant-protection unmanned aerial vehicle to control rice sheath blight. The results showed that the control effect of applying ultra-low-capacity spraying technology by plant-protection unmanned aerial vehicle against rice sheath blight was positively correlated with the dosage of the same fungicide. In the test site of Taihe county,under the condition of uniformly applying 420 g/hm^2 25% Epoxiconazole suspending agent,applying 15. 0 L/hm^2 liquid medicine by unmanned aerial vehicle had the highest control effect（ 84.20%）,which was significantly higher than the control effect（ 81.83%） of applying 450.0 L/hm^2 liquid medicine by artificial electric sprayer. In the test site of Nanchang county,under the condition of uniformly applying 375 g/hm^2 40% Prochloraz copper salt· Epoxiconazole suspending agent,the control effect of applying 7.5 ~ 15.0 L/hm^2 liquid medicine by unmanned aerial vehicle was 53. 73% ~ 69. 44%,which was significantly lower than the control effect（ 86.72%） of applying 450.0 L/hm^2 liquid medicine by artificial electric sprayer.
