旱育秧使用高吸水材料种衣剂的效果

Effect of seed coating agents made from highly absorbent materials on rice seedlings grown in dryland

水稻旱育秧时采用高吸水材料种衣剂“旱抛成功”和“旱秧保姆”拌种，能实现带土抛栽，提高出苗率和成秧率，增加分蘖、根数、单株鲜重和绿叶面积，减轻病虫危害。拌“旱抛成功”较对照增产１１％，拌“旱抛保姆”增产９．５％。

Two kinds of coating agent made from highly absorbent materials were applied for rice seedlings grown in dryland. These seed coating agents helped throwing rice seedlings together with soil lumps. They singlificantly increased rate of seedling emergence, rate of living seedlings, numbers of tillers and roots, fresh weight per unit and green leaves area, reduced infestation by plant diseases and insect pests, and increased rice yield by 9.5%-11%.
