摘要: 以骏枣(Ziziphus jujuba Mill.)为研究材料,研究不同时期叶面喷施不同浓度的CaCl2和GA3对骏枣果实裂果及中微量元素的影响。结果表明,在枣果迅速生长期,施用15 g/L CaCl2与20 mg/L GA3,单果质量、果实纵横径显著增加。在枣果白熟期喷施10 g/L CaCl2和20 mg/L GA3,可显著减少裂果、降低吸水率,保持果实的硬度、脆性。在枣果实幼果至白熟期,通过施用适宜浓度钙肥可使枣果实中P、K、Ca、Mg含量显著增加,在枣果白熟转色期喷施适宜浓度赤霉素,果实中P、K、Na含量显著提高,Ca含量呈缓慢积累趋势。幼果期至白熟期外源施用钙肥、白熟期喷施GA3是降低骏枣裂果的重要措施之一。

Abstract: Taking Junzao jujube(Ziziphus jujuba Mill.) as material, the effects of different concentrations of CaCl2 and GA3 on fruit cracking, medium and trace elements of Junzao jujube were studied by spraying different concentrations of CaCl2 and GA3 on the leaves of Junzao jujube at different stages. The results showed that during the growth period of jujube fruit, the weight of single fruit and the vertical and horizontal diameter of fruit were significantly increased by applying 15 g/L CaCl2 and 20 mg/L GA3. Spraying 10 g/L CaCl2 and 20 mg/L GA3 in the white ripening stage of jujube fruit could significantly reduce fruit cracking, reduce water absorption, and maintain the hardness and brittleness of fruit. The contents of P, K, Ca and Mg in jujube fruits increased significantly after long-term application of CaCl2, which was higher than that in medium and post-treatment stage. The contents of P, K and Na in jujube fruits were significantly higher than those in the pre-treatment period when gibberellin was sprayed at white ripening stage, and the content of Ca was slowly accumulated. Long-term application of calcium from young fruit stage to white ripening stage and spraying of GA3 during white ripening stage are important measures to reduce fruit cracking of Junzao.
