| 摘 要： | 为明确滴灌条件下植棉方式对土壤水盐运移的影响，采用田间调查与室内分析相结合的方法，在滨海重度盐碱地开展了起垄沟播和常规平播植棉方式下的水盐运移试验，调查了滴灌前后两种植棉方式不同点位及不同土壤深度的土壤水分、盐分和土壤溶液电导率等指标，分析不同植棉方式土壤水分、盐分和土壤溶液电导率的时空分布特征。结果表明：滴灌条件下起垄沟播的水分入渗深度和盐分淋洗深度均明显大于常规平播植棉方式，起垄沟播植棉膜下(0~20 cm)土壤溶液电导率明显低于常规平播植棉；滴灌对两种种植方式膜外土壤水分和盐分运移未产生明显影响。起垄沟播联合滴灌技术更有利于为棉花生长的水盐环境。研究结果可为盐碱地植棉提供理论参考和实践依据。

| Abstract: | In this study, two typical cotton planting ways, i.e.
the ridgefurrow planting and conventional flat planting, were selected in the
coastal area with severe soil salinization so as to clarify the effect of
different cotton transplanting ways on soil water and salt migration under drip
irrigation. The soil moisture content, soil salinity and soil solution
conductivity at different sites and depths were investigated before and after
drip irrigation. Spatial and temporal distribution characteristics of soil
moisture content, soil salinity and soil solution conductivity were analyzed.
The result showed that the depth of soil water infiltration and salt leaching
in ridgefurrow treatment was deeper than that of
conventional flat planting treatment, and the soil solution concentration in
0-20 cm soil layer in ridgefurrow planting pattern was
lower than that of conventional flat planting treatment. There was no
significant difference in soil water and salt migration outside the plastic
film mulch under the two treatments. The combined drip irrigation technology in
ridgefurrow planting was more conducive to providing a
suitable water and salt environment for cotton growth. This study could provide
both theoretical and practical references for cotton cultivation in saline
soil. |
