３年田间试验资料表明：水稻旱育秧的出苗率和成秧率都比水育秧高；在低温胁迫下，播于旱育苗床的水稻种子存活时间长，具有“土中待晴”的优势；烂秧主要发生在秧苗出土前后和１．１～２．０叶期；受低温胁迫之后出土的秧苗，在一段时间内还会出现死苗现象。在低温期间，旱育秧苗的出叶速度、株高和根系生长都快于水育秧。早粳品种的成秧率明显高于早籼品种。低温累积量，＜１０℃的天数和＜１０℃的雨日是造成烂秧的主要因子。由种子发芽率与低温累积量组成的回归模式，能较精确地模拟成秧率。
The results of field experiment in three years showed that the seedling emergence rate and the seedling emergence rate of rice seedlings were higher than that of watering seedlings. Under low temperature stress, the seeds of rice seedlings planted in dry seedbed had longer survival time and had the advantage of " Rotten seedlings occurred before and after the emergence of seedlings and 1.1 to 2.0 leaf stage; by the low temperature stress after the excavated seedlings, dead seedlings will appear in a period of time. During low temperature, the speed of leaf emergence, plant height and root growth of drought-tolerant seedlings were faster than that of water-saving seedlings. The yield of early japonica rice was obviously higher than that of early indica rice. Low temperature accumulation, <10 ° C days and <10 ° C rainy days are the major contributors to rotting. The regression model composed of seed germination rate and low temperature accumulation can simulate the planting rate more accurately.
