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 jujube orchards with medium fertility level representative of 6 gold and jujube cultivars as the research object, the effects of balanced fertilization of nitrogen, phosphorus and potassium on the growth and development of the jujube were studied. The results showed that the balanced fertilization of N, P and K could increase the number of jujube jujube stems and leaves in jujube jujube increased 1.39 times compared with the control; Increase the average fruit weight of jujube fruit, soluble solids content and dry rate; and can significantly increase the jujube fruit yield; can reduce the jujube fruit cracking rate and the incidence of pulp disease.
