1. The results showed that Sigma Broad had a good control of Veronica didyma, Avena fatra, Vicia sativa, Galium aparine. and Rorippa indica., more significant in term of fresh weight control and the inhibition rate of weed height despite less weed control in term of plant number, which maintained a certain number of weeds, due to delayed use.
结果表明，阔世玛对小麦田婆婆纳、野燕麦、大巢菜、猪殃殃、野油菜等单双子叶杂草有较好的防除效果，春季晚用，对杂草的密度防效不佳，小麦田间保留了一定数量的杂草，但对杂草的鲜重防效、株高抑制率显著。
2. All of these seeds from the wheat field were dead over 2 years after burying. After 2 years, the germinability of the seeds om the wheat field was 57.0%, for Galium aparine and 80% for Veronica persica;
猪殃殃、波斯婆婆纳的种子在旱田中2年内的发芽率为57.0%、80.0%，但在水田内其死亡率达98.7%、100.0%；
