【摘要】 研究结果表明，旱床育秧在旱态条体下，秧苗根系发达，有抗逆、早发、早熟、高产的生长优势和生理生化基础，早稻理论产量分析，比水育秧增产８，９％～２２．０％，同江西１９９１年７．８９万公顷大面积试验示范、每公顷增产稻谷９０１．５公斤、增产１６．４％的结果相吻合。更多还原

【Abstract】 When they were raised on dry land, rice seedlings were well-developed in roots,resistant to stress,early in tillering maturity 1 and showed promlse for growth and higti-yieldness.According to theoretical analysis,this seedling-raising technique caused a yield in-cerease of 8.9～22.0 percent over the conventional one(i.e,raisling seedlings on irrigated land),as was demonstrated in 1994 when this technique was applied to about 79000 hectare of paddyfield, causing 900kg.ha-1 or 16.4 percent of average yield increase.更多还原
