| 摘 要： | 针对旱育秧苗在抛植情况下，苗体轻、根盘小且根部难以带上这一情况，应用水稻秧苗健壮素和高吸水材料，不仅促进了旱育秧苗根系的发育，壮大了根群，提高了单株带蘖数，而且使秧苗根部带上量明显增加，高吸水材料包衣还使秧苗根部形成“蓄水球囊”，明显提高了旱青抛秧的立苗速度和抗植伤能力。

| Abstract: | Because its individual plant in light and its root ball is too small to carry soil,the dry-raised and scattered-trans-planting seedling easily draft in wind and withered in strong sunlight.To solve the problem,we studied the effect of the seed-coatwith rice seedling strengthener and materials with high ability of absorbing water on strengthening the root,promoting the tillersand erecting the plant of dry-raised seedling The results showed that:The using of the seedling strengthener and the materials ofabsorbing water in scattered-transplanting and dry-raised seedling can promote the development of root system,strengthen theroot colony.increase the number of tillers per seedling and the quantity of soil carried by root system of seedling.moreover,thecoat shaped from those materials with high ability of absorbing water can help root system form a ball of storing water,whichmay speed up the rate of seedling erecting and increase the resistance to hurt from transplanting, |
