摘　　要：在大田和干旱棚条件下,研究了种衣剂处理对玉米生长发育的影响。结果表明,种衣剂对改善种子抗(耐)旱性能、提高发芽率、促进植株生长、增加产量具有一定效果。不同种衣剂处理的效果有所不同,锐胜100mL+满适金100mL处理100kg种子的效果最佳;其次为满适金100mL/100kg种子和锐胜100mL/100kg种子处理,两者效果相当。北农玉米种衣剂常规用量(20%克福,2000mL/100kg种子)和八达种衣剂常规用量(20%克福,2000mL/100kg种子)两者效果相仿。Field and drought shed experiments were carried out to evaluate the effects of 5 kinds of drought resistant seed-coatings(DRSC)on enhancing drought resistance and yield.Seed germination,growth,yield formation and some parameters relative to drought resistance were investigated and measured in maize plants treated with and without DRSC.The results showed that all the 5 kinds of DRSC effectively promoted drought resistance and yield in maize.Treated with DRSC 3(T3)had the best effect for germination,root nodu...
