摘要
在田间条件下采用定位试验,研究了不同麦秸还田方式改良盐化潮土的作用和效果。结果表明:不同麦秸还田方式实施5年后,可使土壤容重降低0 19～0 24g/cm3,土壤脱盐率达11 82%～21 06%,春小麦增产17 96%～25 00%,对改善土壤物理性状、促进土壤脱盐、提高作物产量有显著效果。
In the fixed posittion of fields,we studied the improving fuction and effect on salined flavo-aquic soil by different returning wheat straw into field.The result showed that after five years the soil volume weight dropped 0.19～0.24 g/cm^3,the soil desalinization ratio reached to 11.82%～21.06%,the output of spring wheat increased 17.96%～25.00%. It has improving effect marked on soil physical property,advancing soil desalting and rising crop yield by using different returning wheat straw into field.
