黄河三角洲滨海棉田土壤盐分特征研究
Characteristic research on the soil salinity in coastal cotton field of the Yellow River Delta
摘要
Abstract
Using the correlation analysis and principal component analysis methods,the characteristics of soil salini-ty in the cotton experimental field of Yellow River Delta was carried out research .The results showed that:The soil of the experimental region was the moderate salinization,and salt appeared a certain surface aggregation phenomenon .The salt base ions in each soil layer,the Na+was the dominant cation and the Cl-was the dominant anion .These two ions toxic for cotton growth were particularly prominent role .The soil salt content presented the significant positive correlation with the content of Na+,SO42-,Cl-,Mg2+,Ca2+,NO32-and HCO32-.The Na+,Cl-,and SO42-were the major characteristic factors affected the soil salinization of the experimental cotton field .This research results cran be provided the theoretical basis and practical basis for the scientific management of the saline land and sustainable agricultural devel-opment in the Yellow River Delta .关键词
