Abstract: SAR(Super water absorbent resin) can absorb and storage water quickly. The effect of the seed coating chemical, its main ingredient was SAR, on growth of dry-raising rice seedlings were studied. The results showed that the seed coating chemical had no bad influence on the germination percentage and germination energy of rice seedlings, and it could efficiently control the moisture in seedling bed and slowly relieved insecticides and fertilizer, so the ant-disease ability of seedling increased and the quality of seedlings were higher than the control, the seedling maintained dominance in striking root and tillering.

Key words: super water absorbent resin(SAR), seed coating chemical, rice, dry- raising seedling

摘要： 高吸水性树脂具有较强吸水保湿功能,使用高吸水性水稻种衣剂培育旱育秧苗,可以有效控制苗床水分和湿度,同时能缓释农药和肥料,增强秧苗抗逆性。试验表明,高吸水性种衣剂处理对水稻发芽率和发芽势无不良影响,且壮根、壮苗效果显著;能减少病害发生,保持旱育秧苗发根优势和分蘖优势,达到省工省时的目的。
