早稻不同育秧方式的比较研究

比较了早稻不同育秧方式对秧苗素质、产量构成、产量和稻米品质的影响 ,结果表明 :旱育秧的总体效果好于塑盘育秧 ,塑盘育秧又好于水育秧。旱育秧比水育秧增产 1 7.7%～ 2 0 .6 % ,比塑盘育秧增产 5.4%～ 7.9%。在旱育秧 4种不同方法中 ,以简化旱床育秧的效果最好 ,其次是种子包衣旱育 ,再次是育秧肥旱育 ,以壮秧剂旱育的效果最差。不同育秧方法对稻米的品质影响不大

Comparative Studies on Different Methods of Raising Early Rice Seedling

The effects of different methods of raising early rice seedling on the seedling quality, yield component, yield and rice quality were compared, the results showed that the general effect of raising seedling on upland bed was better than that of raising seedling on plastic tray, and the latter was better than that of water cultivation of seedling. Raising seedling on upland bed increased rice yield by 17.7%～20.6% as compared with water cultivation of seedling, by 5.4%～7.9% as compared with raising seedling on plastic tray. Among four methods of raising seedling on upland bed, the simplified raising seedling was the best, the raising seedling with seed-coating chemical application was the secondary, that with fertilizer application was the third, that with seedling-strengthening chemical application was the worst. The effect of different methods of raising seedling on rice quality was not significant.
