摘　　要：于2009~2010年,对宁夏引黄灌区苹果园进行苹果园沟灌节水和覆膜生草试验。结果表明：树盘覆膜具有提高土壤含水量、稳定土壤水分的作用,果园行间生草可降低土壤容重,增加土壤有机质,提高土壤全氮及碱解氮含量。The experiment was carried out to evaluate the effects of film covering and forage planting on soil physical and chemical properties in apple orchard from 2009 to 2010.The results showed that film covering improved soil moisture and stabilized soil temperature effectively;inter-row forage planting lowered soil bulk density and increased soil organic matter,enhanced total nitrogen and available nitrogen contents.
