玉米秸秆隔层改良盐碱土壤及应用于葡萄栽培中的效果初探

摘要

为改良沿海地区盐碱土壤环境，利用秸秆作为隔盐层改良盐碱土壤。试验设置高盐区、低盐区两组。结果表明：秸秆隔层措施对盐碱土壤改良有明显效果。隔层能够通过阻隔土壤水分运动，实现阻隔盐分、抑制返盐的目的。隔层有利于缓冲不同深度土壤盐分的年季变化，降低作物根部土壤含盐量。隔层处理显著提高了葡萄苗的成活率、存活率，葡萄苗新生叶片数也显著高于对照组。%Improving saline-land soil with smaize straw interlayer to improving the coastal saline-land soil.The preliminary result showed that the effect improving saline-land soil with smaize straw interlayer was obvious. Interlayer could impede movement of soil moisture which salt melts in and reduce accumulation of salt in the surface soil. Interlayer could mitigating the season-year change of soil salt in different depth and removed the salinity of plant roots. Grape survival rate and new leaf number of treatment groups are higher than that of control groups.
