不同种衣剂处理对玉米生长发育的影响

Effects of Different Seed Coating Agents on the Growth and Development of Maize

[目的]验证不同种衣剂对玉米生长发育的影响,并为豫北经济经济区筛选合适的玉米种衣剂组合。[方法]选用5种进口杀虫剂和5种进口杀菌剂在豫北地区进行多点大田试验,研究这些种衣剂对玉米发芽率、幼苗素质、田间保苗率及产量的影响。[结果]这些进口种衣剂对玉米发芽无不良影响,甚至有的对发芽还有促进作用。不同的种衣剂对幼苗不同性状有不同的影响,但是杀菌剂满适金与杀虫剂锐胜对玉米田间保苗数有显著作用。锐胜可以促进玉米的产量。[结论]锐胜/满适金可作为豫北地区的玉米合适的种衣剂组合,为豫北地区的玉米高产和稳产提供了技术支持和理论基础。

[ Objective ] The research aimed to investigate the effects of different seed coating agents on the development and growth of maize and screen out the suitable seed coating agents for corn production in the north region of Henan Province. [ Method] Five kinds of foreign insecticides and Five kinds of fungicides were selected to make multiple-point field test in the the north region of Henan Province. The effects of these seed coating agents on the germination rate, seedling quality, field seedlings survival rate and yield of maize were studied. [ Result ] These foreign seed coating agents had no negative impact on the germination of maize ,and some seed coating agents could promote the germination. Different seed coating agents had different effects on the various charaeters of seedlings, but pesticide Maxim and insecticide Cruiser had significant effects on the survival number of field seedling of maize. The yield of maize could be promoted by using Cruiser. [ Conclusion ] Maxim/Cruiser could be used as the suitable seed coating agents for maize in the north region of Henan Province, which provided technical support and theoretical basis for high yield and stable yield of maize in the north region of Henan Province.
