摘要
盐渍土是地球上广泛分布的一种土壤类型,是一种重要的土地资源。黄河三角洲盐渍土分布广泛,多数属滨海盐渍土类型,物理和化学性状较差。我们进行了盐碱土壤修复材料对盐渍土理化性质影响的试验研究,结果表明,通过施用盐碱土壤修复材料,土壤含盐量、土壤容重、土壤的pH值都有所降低,土壤的孔隙度增加,土壤速效N、P、K含量和土壤有机质含量提高,证明盐碱土壤修复材料能改善滨海盐渍土的理化性质,达到土壤改良的目的。
The saline soil is an important land resource extensively distributed on the earth, which distributes extensively in the Yellow River Delta. The soil physical and chemical properties are generally poor. The effect of saline soil restoration material on the coastal saline soil physical and chemical properties is studied. The results show that the saline soil restoration material can improve the soil physical property, such as soil bulk density and porosity, and can obviously improve the soil chemical property,which reduces the content of soil salt and pH values and increases the content of rapidly available N,P,K and soil organic matter. Therefore, the soil fertilizer gets improved and soil environment becomes better. The result of this experiment showed the obvious effect of saline soil restoration material on the coastal saline soil physical and chemical properties.
