Relationship with soil microbial quantity, soil enzyme activity and physicochemical factor between different saline-alkali soil in Hexi Corridor in spring
河西走廊春季不同盐碱土壤中微生物数量、酶活性与理化因子的关系

Objective] In order to indicate the relationship between soil microbial quantity and soil factor. Methods] Selected 11 typical plots under different saline-alkali soils in Hexi Corridor in spring, the soil microbial quantity, the enzyme activity and the physicochemical properties were investigated and variance analyzed, simple correlation analyzed, stepwise regressive analyzed and principal component analyzed. Results] It shows that there were obvious differences between the primary saline-alkali soil, the secondary saline-alkali soil and farmland soil in soil physicochemical properties and soil microbial quantity. The soil microbial quantity was generally at a low level and at regularity: primary saline-alkali soil
