植保无人机结合助剂在小麦赤霉病防治中的农药减量研究

Pesticide-reduction in the Control of Fusarium Graminearum by Plant Protection UAV Combined with Adjuvant

利用植保无人机结合助剂降低农药施用量后对小麦赤霉病进行防治效果研究。结果表明,处理间赤霉病防治效果为:无人机常规用药加助剂处理>无人机常规用药处理>无人机减量25%处理产量加助剂处理>喷雾器处理>无人机减量25%处理>无人机减量50%加助剂处理>无人机减量50%处理。试验还发现防治病害过程中药剂添加植物助剂能有效增加药剂在小麦植株中的覆盖率,促进药剂高效地进入植株内部,在发病初期抑制病情扩展,能够有效降低因病害对产量造成的损失,从而提高农户收益。

Utilizing plant protection UAV combined with Adjuvant to reduce the application rate of pesticides for wheat scab controlling research.The results showed that the control effect of treatment of scab was UAV routine drug plus adjuvant treatment>UAV routine drug treatment>UAV reduction 25% treatment yield plus adjuvant treatment>Sprayer treatment>UAV reduction 25% treatment>UAV reduction 50% plus additive treatment>UAV reduction 50% treatment.The experiment showed that adding plant adjuvant during the disease prevention process effectively increase the coverage of the wheat plants and promote the bactericide into the plants efficiently.In the early stage, adding plant adjuvant could suppress the expansion of the disease, which can reduce the loss caused by the disease, thereby increasing the income of the farmers.
