以玉米品种秋乐151为指示品种，采用裂区设计，用4种不同种衣剂作为主处理，各设5个药种比作为副处理，对玉米种子进行包衣，研究不同种衣剂、药种比对玉米发芽率、出苗率、苗高、茎粗、根长、鲜重，叶绿素含量以及过氧化物酶活性的影响。结果表明，发芽率和出苗率以14.4%帅苗·福美双悬浮种衣剂与种子按 1 ∶ 50比例包衣处理为最佳，均达到了100%；种衣剂处理对幼苗有较大影响，在合适的药种比(1 ∶ 50)处理下，幼苗苗高、茎粗、根长和鲜重比对照均有明显提高。种子包衣对幼苗的生理指标有显著影响。叶绿素含量比对照均降低，但能够促进POD活性。

In this study, using a split plot design, the corn variety Qiule 151 is selected as material, with four different seed coating agents as the main processing, the set five pharmacopoeia ratio as the auxiliary treatment, on corn seed coating, respectively, to explore the effects of seed coatings in different concentration ratios and pharmacopoeia ratio on seed germination, emergence rate, seedling height, stem diameter, root length, fresh weight, chlorophyll content and the activity of peroxidase. The results shows that the germination rate and germination rate of 14.4% Shuaimiao·thiram suspension seed coating and seed according to the ratio of 1∶50 coating is the best, reached 100%; the seed coating treatment on seedling had great influence, the height, stem diameter, root length and fresh weight ratio of seedling are significantly improved. in appropriate pharmacopoeia ratio(1∶50) treatment. The seed coating had a significant effect on physiological index of seedling. Chlorophyll content decreased than that of the check, but it could promote POD activity.
