摘要
研究了三种麦田常用的磺酰脲类除草剂对玉米生长的影响。结果表明,同一种除草剂对不同品种玉米根的生长有不同的抑制作用;在玉米苗期试验中,供试的三种除草剂对玉米的生长均呈现一定的抑制作用;在大田残留试验中,异丙隆的残效期最长,麦佬次之,杜帮巨星最短。
Using the method of modeling addition indoor, the sensitivity of sulfonylurea herbicideS to mai2e was studied. In addition, with the method of planting in pot, the effect of sulfonylurea herbicides to maize in seedling was observed.Finally,with bioassay method, the residue dynamics of sulfonylurea herbicides in wheat soil was detected. The results showed that there were different sensitivities to sulfonylurea herbicides among different maize varieties. The concentration of three kinds of sulfonylurea herbicides beyond ED10 hadan obvious effect on length of roots, height of plant,area of leaves in maize seedling. In the residue dynamics test in wheat soil, the residue time of sulfometuron-methyl is the longest; bensulfuron-methyl,the second;tribenuron-methyl,the shortest.
