中国科学院新疆生态与地理研究所培育的耐盐小麦“石冬 5号”除了高度“耐盐”外 ,还具有丰产、抗旱、抗寒等特点。在“硫酸盐”或“氯化物——硫酸盐”类型土壤的盐分含量 1 5g/l时种植“石冬 5号”,生长接近正常 ,保苗面积可以达到 85% ,产量可以达到 30 0 0—— 3750 kg/ha;在含盐量小于 1 0 g/l的盐渍化的上种植 ,产量可以达到 450 0—— 60 0 0 kg/ha。“石冬 5号”新疆南北农区盐渍化地种植 ,发展速度很快 ,到 1 999年为止 ,种植面积超过 1万公顷。
Salt-tolerant wheat “Shidong 5” cultivated by Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences has the characteristics of high yield, drought resistance and cold resistance in addition to high salt tolerance. In the “sulfate” or “chloride-sulfate” type of soil salt content of 15g / l planted “Shidong 5” near normal growth, seedling coverage can reach 85%, the output can reach 30 0 0- - 3750 kg / ha; on salinized crops with salinities of less than 10 g / l, the yield can reach 450 0-60 000 kg / ha. “Shidong 5” Xinjiang’s northern and southern agricultural areas are planted in saline soils and the development speed is very fast. By 1999, the area under cultivation has exceeded 10,000 hectares.
