摘要:
对覆草3～5a的苹果园和葡萄园土壤进行采样分析。结果表明；果园覆草后土壤有机质提高0.92～3.33g/kg，全氮和全磷的平均值分别提高0.194mg/kg和0.140mg/kg。土壤容重降低0.068g/cm3，田间持水量增加2.82%，CEC提高1.82cmol/kg，pH变化不显著，对土壤有效养分的影响达极显著水平，影响大小的顺序为有效钾>有效磷>有效钾。
Abstract:
The soil of apple orchard and grape orchard which were covered by straw for 3~5 years were analyzed. The results indicated as below: After covering straw the content of soil organism increased by 0.92~3.33 g/kg. Soil bulk density decreased by 0.068 g/cm3. Field moisture capacity increased by 2.82% and CEC 1.82 cmol/kg. But pH was not affected obviously. The content of the total N increased by 0.194 mg/kg and that of the total P did by 0.14 mg/kg. On the other hand contents of soil available nutrients were affected obviously in the order of available K available Pavailable N.
