黄淮海平原是我国重要的农业产区,常因旱、涝、盐碱、风砂的危害,严重影响农业生产的发展。 为了治理黄淮海平原,六十年代中期以来。中国科学院、水科院、农科院以及其他有关单位在五十年代进行的土壤调查研究基础上,进行了较大规模的综合治理试验,取得了显著的成效,特别是井灌井排的应用,对防治土壤盐渍化起了良好的作用。随着土壤次生盐渍化大面积的消除,土壤碱化有所发展,对农业生产的危害性已日益显露,国内外对土壤碱化发生及其防治的研究已不容忽视。
The Huang-Huai-Hai Plain is an important agricultural producing area in China. It is often endangered by drought, waterlogging, salinization and wind sand and seriously affects the development of agricultural production. In order to control the Huang-Huai-Hai Plain since the mid-1960s. The Chinese Academy of Sciences, the Chinese Academy of Agricultural Sciences, the Chinese Academy of Agricultural Sciences and other relevant units carried out a large-scale integrated management experiment based on the soil survey conducted in the 1950s and achieved remarkable results. In particular, the application of well- On the prevention and treatment of soil salinization played a good role. With the elimination of a large area of secondary salinization of soil, soil alkalinization has developed and its harmfulness to agricultural production has been increasingly exposed. The research on the occurrence and prevention and control of soil alkalization at home and abroad can not be ignored.
