寒地盐碱土又称盐渍土 ,地势比较平坦 ,又有良好的热量资源 ,而水稻是适宜在偏酸性土壤中生长的喜温性作物 ,因此 ,寒地盐碱土种稻有其有利条件 ,又有不利因素的制约。本文针对这一特点 ,提出如下的关键技术。1　稀播育大龄壮秧水稻秧苗耐盐碱性较差 ,尤其是三叶龄秧苗耐性最弱 Cold saline soil, also known as saline soil, the terrain is relatively flat, there are good caloric resources, and rice is suitable for the growth of acidic soil in the temperature of the crops, therefore, the cold saline soil of rice has its favorable conditions, There are unfavorable factors. In view of this characteristic, this article puts forward the following key technologies. 1 thin sowing old seedling rice seedlings have poor salt-alkaline resistance, especially the three-leaf-age seedlings of the weakest patience
