应用高吸水种衣剂对水稻种子进行包衣处理，不浸种不催芽直接插入旱育苗床，与未包衣处理进行比较，考察了旱育包衣对分蘖发根、立苗速度、秧苗体内碳水化合物的蓄积及对产量的影响。高吸水种衣剂包衣处理在种子周围及秧苗根部形成了１．８ｃｍ×１．５ｃｍ×１．２ｃｍ左右的“蓄水球囊”，不仅壮大了根群，促进了分蘖，提高了秧苗素质．而且增加了秧苗体内碳水化合物的积累，提高了旱育包衣抛秧稻的产量。
The rice seeds were coated with high water-absorbing seed coating agent. Without soaking seeds, the seedlings were directly immersed in dry seedbed, and compared with uncoated treatment. The effects of dry-curing coating on tillering and rooting, seedling establishment speed, Accumulation of compounds and their impact on production. Superabsorbent coating agent coating around the seed and seedlings formed a root about 1.8cm × 1.5cm × 1.2cm “water storage balloon”, not only to expand the root group, and promote tillering and improve the quality of seedlings . But also increased the accumulation of carbohydrates in the seedlings and increased the output of throwing rice seedlings in dry cultivation.
