以肥床旱育抛秧、塑盘旱育抛秧为对照 ,比较观察了采用“旱抛成功”高吸水种衣剂实施种子包衣 ,免去塑盘直接利用肥床旱育秧抛栽稻的生长发育特性与产量形成的优势。研究结果表明 ,包衣旱育出苗整齐、成秧率高 ,秧苗素质好 ;根部带土 ,抛栽自然直立苗率高、立苗快 ;抛后发根力强 ,分蘖起步早、发生量大 ;群体生长协调 ,各主要生育时期叶面积指数和干物质积累量高 ;每亩有效穗数和总粒数提高 ,结实率与千粒重持平 ,产量增加 10 %以上。 The seedlings were planted in the dry-raised bed of seedling and the plastic-discarded dry-cast seedlings were used as the control. The seed coating was carried out by using the “drought throwing throwing” superabsorbent seed coating, Growth and development characteristics and the advantages of yield formation. The results showed that the seedlings in the dry-nursery seedlings were well-proportioned, the seedling rate was high, and the quality of the seedlings was good. ; Coordination of population growth, leaf area index and dry matter accumulation in all major growth stages; effective panicle per panicle and total grain number increased, seed setting rate and 1000-grain weight were equal, yield increased by 10% or more.
