在盐碱地上种植耐盐冬小麦的综合效益研究

Study on Comprehensive Effect of Planting Salt Tolerance Winter Wheat in Saline Soil

种植耐盐冬小麦，是提高盐碱地生产力、收复弃耕盐碱地、开垦盐碱荒地、提高土地利用的一种最具生态效益、经济效益和社会效益的办法。本文是“科技兴阿”项目中“石冬五号耐盐冬小麦在阿克苏地区盐碱地推广示范”的工作总结。石冬五号耐盐冬小麦在阿克苏地区盐碱地上种植，表现出较好的耐盐、丰产等生态特性和较好的经济效益，同时具有晚播，利于轮作倒茬和改良土壤等作用。

the average winter wheat cultivars can not grow in high saline soil.Planting wheat that could tolerate to salt can raise yield in saline soil..Shidong-5 winter wheat cultivar could endure higher salinity in soil.The yield of Shidong-5 is 1500kh/hm 2 more than other winter wheat in saline soil which salinity is 1.1%.It's seedling rate,salt resistance and productivity are higher.Shidong-5 could produce more wheat straw to raise livestock so we could apply more muck into soil which could improve fertility of soil.Farmer could increase their income through planting Shidong-5 winter wheat in saline soil.It may be a better way to reclaim abandoned saline soil.
