摘要
为探索在花生田应用无人机喷洒茎叶处理除草剂的可行性,本研究以人工背负式喷雾器喷施作为对照,选用4种除草剂并设置不同配比,对四旋翼无人机喷施除草剂的防效进行评价。结果表明,在所选药剂推荐剂量下,无人机施药对花生安全,对杂草的综合防效为73.6%~97.6%。无人机施药对杂草防效及对花生安全性与对照间无显著性差异,但喷施除草剂药量及用水量缩减至对照用量的1/30。田间杂草可使花生单株荚果数显著降低,进而造成产量下降,其中苘麻的影响效果最为明显。因此,在以苘麻为优势种群的花生田,推荐480 g/L灭草松水剂与960 g/L高效氟吡甲禾灵乳油桶混后运用无人机喷洒,防效可达97.6%,增产1.63%~229.89%。
In order to explore the feasibility of herbicide spray for stem and leaf treatment by Unmanned Aerial Vehicle(UAV)in peanut field,4 herbicides were selected with different content proportion for UAV spraying and manual spraying.The results showed that spraying herbicides for UAV was safe to peanut under the recommended dose,and the comprehensive control effect was 73.6%~97.6%.The control effect of UAV and manual spraying had no significant difference,while the dosage of herbicide by UAV could be reduced to 1/30 of the dosage by manual.The weeds can significantly decrease the pods number per plant and lead the yield decline,among which Abutilon theophrasti Medicus has the most obvious negative effect on peanut yield.Therefore,it is recommended that using Bentazone(480 g/L)and haloxyfop-P-methyl(960 g/L)with UAV to conrol Abutilon theophrasti,which is the dominant weeds in peanut field,and the control effect would reach 97.6%,and comparing with other treatment group,the yield of pod increased 1.63%~229.89%,the yield of seed increased 1.11%~236.19%.
