幅员辽阔的新疆是我国最大的盐碱土区,盐渍土面积占全国的1/3,达8.5万km~3,其中相当多的盐渍化土地长期无法利用。随着经济发展,新疆水资源越来越紧张,靠以前大水灌田以洗去盐分的方式已不可持续,而滴灌技术也解决不了土壤盐分的出路。但新疆克拉玛依市小拐乡小拐村的盐碱土地上则一片则郁郁葱葱,植物满满地挤在地里。这是中科院新疆生地所研究员田长彦和他的团队经过10年努力,筛选出的适合在盐碱地种植的野榆钱菠菜、
The vast territory of Xinjiang is China’s largest saline-alkali soil area, accounting for one-third of the country’s saline soil area, reaching 85,000 km ~ 3, of which a large number of salinized land can not be used for a long time. With the economic development, water resources in Xinjiang are getting more and more tense. It is unsustainable to irrigate the salt water by irrigating the floodwater before. However, drip irrigation technology can not solve the problem of soil salinity. However, there is a lush area on the saline-alkali land in Xiaojiao Village, Xiaoqiu Township, Karamay City, Xinjiang. The plants are packed in the ground. This is Tian Changyan, a researcher at Xinjiang Institute of Geology, Chinese Academy of Sciences and his team after 10 years of hard work, screened wild elm money spinach planted in saline soil,
