针对北疆地区土壤盐化制约农业发展的问题,通过野外实地分层采集土样,分析北疆地区长期膜下滴灌农田种植前后土壤水分和盐分分布特征。统计学分析表明,种植期土壤含水量变异属于中等偏弱变异强度,土壤盐分的变异属于中等偏强变异程度,土壤盐分分布成自上而下先增大再减少的波动趋势。在空间分布上,土壤水分和盐分种植前后存在明显的差异,种植后在浅层土壤水分和盐分的含量成西高东低的变化分布。
Aiming at the problem of soil salinization restricting agricultural development in northern Xinjiang, soil samples were collected in the field through field stratification to analyze the distribution characteristics of soil moisture and salinity before and after long-term application of drip irrigation in northern Xinjiang. Statistical analysis showed that the variation of soil water content at planting stage belonged to moderately weak variation intensity, the variation of soil salinity was moderately strong degree of variation, and the distribution of soil salinity increased and then decreased from the top to the bottom. In spatial distribution, there was a significant difference between soil moisture and salt before and after planting. The content of soil moisture and salt in shallow soil after planting was high in the east and low in the east.
