保墒旱育秧对不同类型水稻品种的增产作用

Effects of Soil Moisture Conservation Dry Nursery on Yield of Different Type Rice

不同类型水稻品种保墒旱育秧试验结果表明,保墒旱育秧较常规旱育秧有一定的增产优势。增产原因在于保墒旱育秧播种早、播量低、秧苗素质好、分蘖能力强,早育早插延长了有效分蘖期,有效分蘖增加,从而获得更多的收获穗数,最终实现高产。

An experiment was carried out to study the effects of soil moisture conservation drought seedling on different type rice varieties. The results showed that the yield of soil moisture conservation drought seedling was better than conventional dry nursery. Because the soil moisture conservation drought seedling had early sowing, small sowing quantity, good quality, strong tillering ability, and increased the effective tillering stage and effective tillering, thereby gained more spikes, achieved high yield.
