摘要
以中天杨(Populus×xiaozhuanica‘Zhong-tian’)为试验对象,选用11种杀虫剂为试验药剂,分析了在杨树自流式注药过程中注药时间对药液吸收速率的影响。结果表明:3个注药时间中药剂的吸收速率由高到低依次是3月、7月、9月。杨树自流式打孔注药应选择在3月和7月,9月不宜采用注药法防治杨树病虫害。
With Populus×xiaozhuanica ‘Zhong-tian’, 11 kinds of pesticides were selected as the test agents, and the effect of injection time absorption rate was analyzed in the process of auto flowing trunk injection of poplar. The absorption rate of the three injection time from high to low is March, July, and September. The auto flowing trunk injection of poplar could be conducted in the March and July, but it is not suitable for the prevention and control of the poplar pests in September.
