摘　　要：为了明确生草覆盖生态修复方法对苹果园土壤养分的改善效果,分析苹果园生草覆盖生态修复对土壤养分的改善影响。选取渭北旱塬果园作为苹果园生草覆盖生态修复试验地,在苹果园中选取三种生草作为生草覆盖的草种,选取未生草覆盖的苹果园土壤作为生草覆盖土壤的对比土壤,测定不同组土壤的pH值、土壤硬度以及有机质等指标,确定苹果园生草覆盖改善土壤养分情况。试验结果表明,生草覆盖后,苹果园土壤中的有机质、有效磷、水解氮、速效钾、pH值明显提升,苹果园生草覆盖可以改善土壤养分,提升苹果产量与质量,生态修复效果明显。In order to clarify the effect of the ecological restoration method of green grass mulching on the improvement of soil nutrients in apple orchard,this paper analyzed the effect of ecological restoration of green grass mulching on the improvement of soil nutrients in apple orchard.The Weibei dryland orchard was selected as the experimental site for ecological restoration of green grass mulching in the apple orchard.Three kinds of green grass were selected as the grass seeds of green grass mulching in the apple orchard,and the apple orchard soil without green grass mulching was selected as the contrast soil of green grass mulching soil.The pH value,soil hardness and organic matter of different groups of soil were measured to determine the improvement of soil nutrients by green grass mulching in the apple orchard.The results showed that the organic matter,available phosphorus,hydrolyzed nitrogen,available potassium and pH value in the apple orchard soil were significantly improved after straw mulching.The straw mulching in the apple orchard could improve the soil nutrients,increase the apple yield and quality,and the ecological restoration effect was obvious.
