通过新疆121团不同滴灌年限土壤盐分取样分析看出:受人类活动的影响土壤盐分从表层向底层转变;随着耕种时间的延长,土壤平均含盐量累积情况呈先减小后增大的运移趋势;土壤各层含盐量之间关系随耕种时间的延长呈现一定的关系。该结果为盐碱地棉花膜下滴灌土壤水盐次生盐渍化的治理与防治提供了科学依据。 Through the analysis of soil salt sampling in different drip irrigation years of 121 groups in Xinjiang, it shows that soil salinity changes from the surface to the bottom under the influence of human activities. With the extension of cultivation time, the accumulation of soil salinity decreases first and then increases The trend of soil salt content in different layers showed a certain relationship with the prolongation of cultivation time. The results provided a scientific basis for the control and prevention of secondary salinization of soil water and salinity in saline soil and cotton under drip irrigation.
