摘要
通过对玉米药害指数、株高及产量的测定,研究了拌种剂辛硫磷与3种除草剂(耕杰、玉农乐和玉尔乐)共同使用对玉米生长的影响。结果表明:辛硫磷3mL/kg+55%耕杰2700mL/hm2、辛硫磷3mL/kg+40%玉农乐2250mL/hm2、辛硫磷3mL/kg+38%玉尔乐2250mL/hm2均可显著提高玉米的药害指数。辛硫磷和3种除草剂单独使用对玉米的株高及产量均有一定的抑制作用,联合作用表现为相加或拮抗作用。
The effects of co-utilization of phoxim and three kinds of herbicides on maize growth were studied by detecting the phytotoxicity index,plant height and yield.The results showed that 3 mL/kg phoxim and 2 700 mL/hm2 mesotrione,3 mL/kg phoxim and 2 250 mL/hm2 nicosulfuron,and 3 mL/kg phoxim and 2 250 mL/hm2 atrazine could increased significantly the phytotoxicity index.The single use of phoxim and three hrbicides could inhibit the plant height and yield,while the co-utilization showed additive and antagonistic effect.
