摘　　要：为了明确沧州金丝小枣枣园浅层土壤的养分含量,选取具有代表性的3个枣园,测定其0～40 cm土层的土壤养分含量。结果表明:3个枣园土壤有机质含量偏低,不能满足枣果生长对有机质的需求,尤其是枣果生长后期,致使制干枣果肉松果轻、缺乏柔韧性,品质、口感和制干率都有所降低;长期施用氮、磷、钾等大量元素肥料,导致土壤板结,有些土壤表层产生绿苔,造成土壤轻微盐渍化。针对金丝小枣树根系在土层内的分布特点以及土壤养分含量,制定了该地区枣树的施肥策略:建议增施有机肥,适量施用无机肥,有机肥与无机肥配合施用;幼龄小树多施氮肥以促进树体快速成型,开甲以后的大树要少施氮肥、多施有机肥和磷钾肥。The soil nutrient contents of 0-40 cm layer from three representative Ziziphus jujuba cv.Jinsixiaozao orchard in Cangzhou were determined.The results showed that the organic matter content was low,which could not meet the demand for fruit growth,especially at late growth stage,resulting in the loosen flesh,light weight,and lack of flexibility of dried fruits,and the quality,taste and drying rate decreased.The long-term application of N,P and K caused soil compaction,green moss on some of soil surface,and slight soil salinization.According to the root distribution characteristics in soil and the soil nutrient contents,the fertilization strategies were developed including increasing application of organic manure,adequate application of chemical fertilizers,combined application of organic manure and chemical fertilizers,supplying more nitrogen for young trees,and supplying less nitrogen and more organic manure,phosphorus and potassium for big trees with band girdling.
