萌前型除草剂对草坪草的影响和杂草防除研究

Influence of Several Pre-emergency Herbicides on Turfgrass and Controlling Weeds.

通过盆栽试验研究了4种萌前型除草剂(禾草净、农思它、施田补、乙草胺)对草坪草生长的影响和杂草防除效果。试验结果表明:除草剂对草坪草生长有不同程度的影响,其中乙草胺对草坪草影响最大,产生了伤害作用,不宜在草坪中使用;各种除草剂对杂草都有不同程度的防除效果,其中农思它和禾草净效果较好,乙草胺对杂草的防除效果最差。

Influence of several pre_emergency herbicides on turfgrass and controlling weeds was studied through potted plants.The results showed that herbicides had affected the growth of turfgrass in different degree,but the effect was not evident,that acetochlor had severely influenced the growth of turfgrass and should not be applied in lawn.The four herbicides could control weeds to some extent,with oxadiazon and hecaojing being high effective on controlling weeds,and acetochlor being low effective.
