试验采用模拟的形式利用水的大热容量和强的流体特性以及取材容易、成本极低的特点，对早春育苗实行强化保温。目的是大幅度提早播种期，使当地的生育期延长２０～３０ｄ。提高当地稻作产量２０％左右，使绝大多数稻作区的水稻公顷产量稳定在１００００ｋｇ以上。 初步试验结果显示强化保温育苗法效果较正常旱育苗提早１５ｄ（４０月１３日），播种处理已突破育苗期－５～－６℃的低温关，较普通旱育苗法提早出苗１０～１５ｄ。插秧前取样调查结果表明，叶龄进程、分蘖发生及鲜重等都显示出极强的优势，证明了这一方法的有效性，已达初步的试验的目的。
Experiments using simulated forms of large heat capacity and strong fluid properties of water and drawn easy, low cost features, early spring nursery implementation of enhanced insulation. The purpose is to significantly advance the sowing period, so that the local growth period of 20 ~ 30d. Increase about 20% of the local rice production, so that the vast majority of paddy area rice hectare yield stable at 10000kg above. The results of preliminary experiment showed that the effect of enhanced incubation was better than that of normal drought 15 days earlier than that of normal drought (40th, 13th). The sowing treatment had exceeded the low temperature of -5 ~ -6 ℃ in seedling stage, and earlier than the normal drought nursery for 10 ~ 15 days. The results of sampling before transplanting showed that leaf age, tillering and fresh weight all showed extremely strong advantages. It proves that this method is effective and has reached the goal of preliminary experiment.
