高吸水种衣剂应用于杂交籼稻汕优６３、常规粳稻武育粳３号，对２５、３０、３５、４０天秧龄的秧苗都具有显著的壮根壮苗效果，比未包衣对照单株总根数增加２７７％～３９４％，带蘖数增加３３３％～５００％，带土重增加２５１～４．２９倍。抛栽大田后，立苗速度快，各主要生育期的叶面积指数和干物质积累量均明显提高，产量增加５３５％～１３０３％。不同秧龄间的效应，汕优６３以３５天秧龄、武育粳３号以３０天秧龄表现较好。 Superabsorbent seed coating applied to indica hybrid rice Shanyou 63, conventional japonica rice Wuyujing 3, 25,30,35,40 days of seedling age seedlings have significant strong root and strong seedling effect than uncoated control plants The total number of roots increased 277% ~ 394%, the number of tillers increased 333% ~ 500%, with soil weight increased 251 ~ 4.29 times. After throwing the field, the planting seedling speed, the main growth period of leaf area index and dry matter accumulation were significantly increased yield increased by 5  35% ~ 13  03%. The effect of different seedling age, Shanyou 63 with 35 days seedling age, Wuyujing 3 to 30 days seedling age performed better.
