土壤盐渍化造成土壤退化和质量下降,如何改善盐渍化土壤质量问题是国内外学者研究的难点。作者就盐渍化土壤改良剂进行相关研究,针对盐渍化土壤,在试验室对31种常见物质在室内培养进行初次筛选,并时改良后盐渍化土壤的EC值和pH值进行测定,其中葵粕、棉粕、柠檬酸、沼液改良盐渍化土壤效果较好。
Soil salinization causes degradation and degradation of soil quality. How to improve the quality of salinized soil is a difficult problem for scholars at home and abroad. In this paper, the author studied the salinization soil improver. For the salinized soils, 31 kinds of common substances were primarily screened in the laboratory in laboratory and the EC and pH of salinized soils were determined. Among them, sunflower meal, cottonseed meal, citric acid and biogas slurry improved soil salinization better.
