摘要
进行了乙草胺90%乳油30,60,90mL/667m2三个剂量对小麦出苗与幼苗生长的影响试验,结果表明:小麦播后苗前施用乙草胺在土壤潮湿或遇较强的降水时,施用量60mL/667m2对小麦的出苗及幼苗生长造成明显的药害。播种后10d的出苗率较空白对照降低了5%～25%。出苗后3周,受药害幼苗的生长量(高度)较空白对照降低11.62～13.08cm。
The effect of applying 90% acetochlor EC 30, 60, 90mL/667m^2 for wheat germination and seedling growth were tested. The results showed that 60 mL/667m^2of 90% acetochlor EC had significantly damage for wheat seeding number and growth with heavy rain or wet soil before sowing. There was 5%-25.0% of the seeding number less than the control 10 days after sowing. Growth quantity of injured seedling was 11.62-13.08cm lower than control after 3 weeks seedling.
