摘　　要：以6个金丝小枣主产县市具有代表性的中等肥力水平的枣园为研究对象,研究了氮磷钾平衡施肥对金丝小枣生长发育的影响。结果表明:氮磷钾平衡施肥能增加金丝小枣二次枝抽生枣股数,比对照增加1.39个;枣股抽生枣吊数比对照增加0.7个,果吊比增加0.8;能有效增加枣果的平均单果重、可溶性固形物含量及制干率;并能显著增加枣果产量;能降低金丝小枣裂果率及浆烂病发病率。Taking the orchards that had a moderate level of fertility and representative in 6 main producing counties as object,the effect of balanced NPK fertilization on the growth of Ziziphus jujuba Mill. cv. Jinsixiaozao were studied. The results showed that the effective mother fruit branch and the output of jujube branch were increased under balanced NPK fertilization,the mean fruit weight, the soluble solids content and the radio of dried jujube had improved. The yield was significantly increased. The incidence of thick rotten disease and fruit cracking were reduced.
