通过草铵膦、百草枯和草甘膦3种灭生性除草剂2次田间试验,发现对杂草作用最快的是百草枯,最慢的是草甘膦。试验得出,草铵膦400 g/hm2能有效防除马齿苋、反枝苋、鳢肠和委陵;800 g/hm2能有效防除稗草、马唐和苘麻;百草枯400~800 g/hm2能有效防除反枝苋、鳢肠、委陵、稗草、马唐、苘麻和莎草科杂草;草甘膦800 g/hm2就可防除本试验田的杂草。
Through field experiments with three kinds of herbicide of glufosinate, paraquat and glyphosate, we found that paraquat was the fastest acting on weeds and glyphosate was the slowest. The results showed that glufosinate 400 g / hm2 can effectively prevent the recovery of purslane, arrowhead amaranth, colon gruel and dressing; 800g / hm2 can effectively control barnyardgrass, crabgrass and hemp; Paraquat 400 ~ 800g / hm2 can effectively control the weeds in the experimental field, which is controlled by glyphosate 800 g / hm2.
