Weed Seedbank and Chemical Control in Soybean Field of South China
摘要
Abstract
Field trials were conducted at post-emergence to evaluate the control effect of six herbicides in spring soybean field, South China. The relationship between weed seedbank and chemical control was studied by seedbank lure grows method and field efficacy trials method. The results showed that 10 species of weed were investigated and mainly distributed in 0-10 cm soil. The highest density was 6861 plant·ha-1 in the weed seedbank, while the field density of weed was 208 planf·ha-1 Just 3.03% of the seedbank;six kinds of herbicides had good control effect,especially 7.5% acifluorfeno quizalofop-P-ethyl EC. The weed of grass family,dicotyledon,cyperaceae was controlled by 70.7% -72.4% at 45 days after post-emergence treatment and the soybean yield was increased by 20.5% -34.5% .关键词
