摘　　要：应用高吸水种衣剂种子包衣,研究其在扬粳4227机插秧上的应用效果,分析不同药种比种子包衣处理对水稻秧苗出苗率、成苗率、秧苗素质及秧苗根系形态特性的影响,结果表明,适宜药种比包衣(1∶30)处理出苗率、成苗率分别比不包衣处理高出3.93个百分点和7.35个百分点;且壮秧率大幅度提高,秧苗素质明显增强;同时还起到了适当增强秧龄弹性,延长适栽期的效果。Using good water absorbent seed-coating material to study its application effects on the mechanical transplanting super rice variety Yanggeng 4227, the effects of different pesticide-seed ratio （0; 1：15; 1：30; 1：60） on the seedling emergence rate, seedling rate, seedling quality and seedling root morphology characteristics were studied. The result indicated that： the seedling emergence rate, seedling rate under appropriate amount of pesticide-seed ratio with 1：30 was increased by 3.93 percentage point and 7.35 percentage point respectively compared with non-coated seed processing. Generally, appropriate amount of pesticide-seed ratio treatment could increase the rate of strong seedlings significantly, improve the elasticity of seedling age and extend transplanting date.
