水稻保温保墒旱育秧,是利用冬灌蓄水保墒,薄膜复盖保温,旱播旱长的一种育秧方法.这种育秧方法具有早育早插,早熟高产;秧苗健壮,适应机插;以及出苗率较高,节省种子,管理比较简便等优点.在气温比较正常的年份,保温保墒旱育秧可比水育秧增产8～10%,比卷秧增产2～5%.1972年在气温不正 Preservation of rice moisture preservation drought seedlings, is the use of winter irrigation water and soil moisture, film cover insulation, drought drought a method of growing seedlings. This method of early seedling with early planting, early maturity and high yield; seedlings robust, adapted to machine insert; Higher, save seeds, the management is relatively simple and so on.At normal temperature in the year, insulation moisture moisture drought-tolerant seedlings than aquatic seedlings yield 8 to 10%, than roll-seedling yield 2 to 5% .1972 in the temperature is not correct
