摘要
经过 1988～ 1990年研究 ,初步摸清了豚草的生物学特征和发生规律 ,确定了防除用药剂和人工防除的适期 ,提出了一次性防除豚草的新策略和技术 ,解决了多次用药防除费用大的难题。给大面积防除豚草提供了新途径 ,并已实际应用。 1989～ 1991年三年中累计防除面积达到3333余 hm2 ,防效均在 98%以上。已基本扑灭豚草。
Through research works during 1988～1990,the biological characters and occurrence regularity of common ragweed were preliminarily cleared,the opportunities of chemical control and hand weeding were determined,new one shot controlling strategy and techniques were advanced,the problem of large expenses in chemical control was solved,so a new path was opened for controlling the weed in an extensive area. These techniques are already put into practice.The accumulated ragweed controlled area during 1988～1990 amounted to 3333hm 2 with a control efficiency of 98% or more always.This weed was basically eradicated.
