本文研究了种植条件下不同调控措施对土壤表层５ｃｍ处电导率的影响状况并将表层电导率变化曲线划分为三个阶段．分析了施肥、灌溉、覆盖、以及施用改良剂等调控措施，对土壤盐分在不同阶段的过程及机理的差异．施肥、灌溉主要是在作物生长后期对水盐运移发挥作用 ，而施用改良剂对前期水平间的差异较大，后期可降低土壤表层电导率．在影响程度上，施 肥与灌溉水平间的差异比覆盖和施用改良剂要明显．
In this paper, the effect of different control measures under different planting conditions on the conductivity at soil surface 5 cm was studied and the curve of surface conductivity was divided into three stages. The control measures such as fertilization, irrigation, covering and application of improver were analyzed. The differences of the process and mechanism of soil salinity at different stages were analyzed. Fertilization and irrigation were mainly responsible for water and salt transport during late crop growth. However, application of improver had a great difference between the initial stage and late stage, which could reduce soil surface conductivity. In terms of impact, differences between fertilization and irrigation levels are more pronounced than covering and applying amendments.
