中文摘要	覆沙是甘肃陇东半干旱地区苹果园土壤管理的一种主要形式,具有增温、保墒、提高果品产量和质量等作用。对陇东旱塬地区覆沙苹果园土壤养分测定的结果表明: 2007年至2017年,10年间土壤有机质含量平均下降了0.91 g /kg,下降8.67 %;全氮、全磷和全钾含量分别下降了1.23%,1.14%和1.33%; pH值达到8.59,提高了4.50%。有机肥+化肥配方肥料试验结果表明,三种肥料配方处理均极显著地增加了一年生枝条数量,适量施氮、磷,促进了苹果叶片的生长,但过量施用抑制了百叶重量的增加。配施肥料处理平均单果重和可溶性固形物含量极显著高于对照,不同处理间果形指数、果实硬度、有机酸、水分等果实品质指标差异不显著。
英文摘要	Sand cover is a main way of soil management in apple orchards in the semi - arid region of east Gansu. It can keep warm,preserve soil moisture and increase yield and quality of fruit. The soil nutrient content of sand covered apple orchard was assayed after fertilization. The results indicated that the content of soil organic matter decreased an average of 0.91g /kg,an 8.67% decline between 2007 and 2017,and the content of total nitrogen,total phosphorus and total potassium decreased by 1.23%,1.14% and 1.33%,respectively; whereas the pH of soil was as high as 8.59,increased by 4.50%. In addition,the number of annual branch increased remarkably with combined application of inorganic fertilizer and organic manure in all the treatments,and an appropriate nitrogen (N) and phosphorus (P) application rates could promote effectively the growth of apple leaves while excessive fertilization would inhibit the increase of leaf weight. The average fruit weight and soluble solid content of combined applications of organic and inorganic fertilizers were significantly higher than the control. However,there were no differences for fruit shape index,fruit firmness,organic acid,and water content among the all treatments.
