种衣剂副作用的研究进展

种衣剂在中国已经广泛应用于农业生产，它的应用对于防治苗期病虫害、促进作物生长、增加农民收入起到重要作用，但在生产过程中也存在很多问题。综述了近20年来国内外各种作物种衣剂的副作用现状，例如种衣剂普遍抑制作物生长，影响种子出芽率，造成苗弱、抗逆性差，且污染环境、影响粮食品质等。提出运用新型高分子材料对种衣剂的成膜剂加以改进，同时利用生物技术对种衣剂副作用进行防控。分析表明拌种的同时加入促生长助剂或生物材料聚谷氨酸，能有效提高作物发芽率，促进成苗，提高农作物潜能，能很好地控制和降低种衣剂副作用。

Advance of Studies on Seed Coating Agents Side Effects

Seed coating agent has been widely used in agricultural production, and has played an important role in controlling seedling diseases, promoting crop growth and increasing farmers' income. However, there are still some problems besides its advantage. This study reviewed the application and side effects of various seed coating agent for different crops both here and abroad during past 20 years, for example seed coating inhibit plant growth, affect seed germination rate, result in weak seedlings, poor resistance, and pollute the environment, affect food quality and so on. After summarizing the disadvantage of seed coating, the author prospected that use new polymer materials to improve seed coating film-forming agent, and discussed the use of biotechnology to prevention and control of the seed coating side effects. Analysis shows adding growth-promoting additives or biological materials polyglutamate while dressing seed, can effectively improve crop germination, improve crop potential, well control and reduce side effects.
