摘　　要：以清耕为对照,研究分析了人工种植紫花苜蓿草与自然生草对果园土壤的培肥效果。结果表明:人工与自然生草均能提高土壤(0～30cm土层)有机质含量,且以表层土壤增加更为显著;人工与自然生草处理0～30cm土层土壤速效氮、速效磷和速效钾均有不同程度的提高,土壤微生物数量也有显著增加。表明生草能显著培肥土壤,在干旱区果园紫花苜蓿草的人工种植应大力推广。Taking clean tillage as CK,the effects on the orchard soil fertility by artificial alfalfa grass and natural grass were analysised.The results showed that both the artificial and natural grass could improve the soil organic matter content,especially in surface soil,N,P and K content,and microbial quantity in 0～30 cm layer of soil.Grass could significantly improve soil fertility,therefore,planting alfalfa grass in arid areas orchard should be vigorously popularized.
