摘要
[目的]明确2种土壤处理除草剂乙草胺和莠去津对玉米的安全性。[方法]采用盆栽法,以不同剂量的乙草胺、莠去津在玉米播后苗前土壤表面喷雾处理,研究其对玉米的影响。[结果]乙草胺在推荐剂量的0.5-6.0倍用量下对玉米出苗率无显著影响,但显著抑制玉米株高和鲜重;莠去津在推荐剂量的0.5-6.0倍用量下对玉米出苗率、株高、鲜重均无显著影响。[结论]播后苗前土壤表面喷雾处理,乙草胺对玉米安全性较差,莠去津对玉米安全。
[Objective] The aim was to test the security of acetochlor and atrazine to maize. [Method] In the pot experiment,herbicides were applied immediately after the seeding at different dosages,which were 0. 5- 6. 0 fold to the recommended dosage. [Result] Acetochlor had no effect on the emergence but remarkably reduced the height and the fresh weight at the tested dosages. Atrazine had no effect on the emergence,height or fresh weight. [Conclusion] Acetochlor had low security to maize but atrazine was safe.
