| 摘 要： | 通过对2009年膜下滴灌土壤水盐运移的试验研究,结果表明:膜下滴灌条件下土壤水分的再分布决定了土壤盐分的分布特征,土壤平均含水率在棉花全生育期内呈现逐渐上升的趋势.在棉花生长阶段,随着灌水量的增加,土壤盐分峰值位置呈现下移的趋势.当灌水量从3 000 m3/hm2增加到4 800 m3/hm2时,盐分峰值位置向垂直方向...

| Abstract: | Because of the irrigation regime and natural factors,soil salinazation has become more and more severe in arid regions. A 3-year field experiment was carried out to investigate the effects of different drip irrigation regimes on soil salinity distribution and cotton yield at Aksu National Station for Farmland Ecosystem Scientific Research,Chinese Academy of Sciences. The results show that the distribution of soil salinity was affected by the redistribution of soil moisture content. Average soil moisture con... |
