摘　　要：The research explored adaptability maize seed coating agent in spring sowing and effects of ultra-fine powder shaped areas in northeast China. The results showed that germination potential and rate both improved around 5% and the num- ber of root increased by 4% in the treatments with ultra-fine powder shaped maize seed coating agent compared with the control group without seed coating. What＇s more, the treatments with ultra-fine powder shaped maize seed coating agent took advantages in terms of fresh weight of seeding, stem diameter, and dry weight. It is notable that control effects on underground insects performed the best, with per- centage over 94%, which is more excellent relative to other agents in markets. Therefore, ultra-fine powder shaped maize seed coating agent can be widely applied in spring sowing areas in northeast China, without side effects.研究新型超微粉体玉米种衣剂在东北春播地区的适应性及使用效果。结果表明,与未包衣空白对照相比,超微粉体玉米种衣剂发芽势、发芽率均提高5%左右,总根数增加4%以上,幼苗鲜质量、茎粗、干质量与空白对照相比具有明显的优势,后期能提高玉米产量;尤其在对北方地区地下害虫的预防效果最佳,达到94%以上,显著优于东北地区其他市售种衣剂。超微粉体玉米种衣剂在东北春播地区适应性强,全生育期无毒副作用。
