摘　　要：为了探索种衣剂在杂交水稻苗期的应用效果,采用2.5%吡·咪、3%恶·咪、锐胜和适乐时包衣深两优5814种子,测定发芽率,调查成秧率、秧苗素质及稻蓟马防效。结果表明:锐胜与3%恶·咪能提高种子发芽率,但4种种衣剂处理的种子的成秧率无明显差异;各处理组的株高、叶面积和总根数与对照相比无明显差异,但锐胜处理组的株高大于3%恶·咪处理组、叶面积大于2.5%吡·咪处理组、总根数大于3%恶·咪和2.5%吡·咪处理组、苗干重大于2.5%吡·咪处理组,秧苗的综合素质以锐胜处理组为佳;各种衣剂对稻蓟马均有防效,其中锐胜和2.5%吡·咪处理组的防效较好。In order to explore the effects of application of seed-coating agents on hybrid rice in seedling, the hybrid rice seeds of Shenliangyou5814 were coated with 2.5% imidacloprid-prochloraz, 3% hymexazole-prochloraz, Cruiser and Celest, respectively, and the germination rate, the percentage establishment of seedling, the seedling quality and the control effect of rice thrips were investigated. The results showed Cruiser and 3% hymexazole-prochloraz promoted the germination rate, but the percentage establishment of seedling showed no significant difference among the seeds coated with the four seed-coating agents. The plant height, leaf area and total root number showed no difference between the seeds coated with the four seed-coating agents and the control seeds, but the plant height dealed with Cruiser was higher than that dealed with 3% hymexazole-prochloraz, the leaf area dealed with Cruiser was larger than that dealed with 2.5% imidacloprid- prochloraz, the total root number dealed with Cruiser were larger than that dealed with 3% hymexazole-prochloraa and 2.5% imidacloprid-prochloraa, and the seedling dry weight dealed with Cruiser was higher than that dealed with 2.5% imidacloprid-prochloraz. The comprehensive seedling quality of rice seeds dealed with Cruiser was the best. The four seed-coating agents showed control effect to rice thrips. Among them, Cruiser and 2.5% imidacloprid-prochloraz were more effective.
