2007—2010年,我们对新疆阿克苏市依杆其乡哈尼喀村赞皇大枣示范园进行调查研究,明确该园丰产的关键技术在于5月上旬至7月下旬及时抹除已成形的新生枣头;夏季及时对少量保留的新生枣头、二次枝及前1年枣股抽生的枣吊和木质化枣吊进行摘心。夏剪可显著提高枣树的产量和品质,实现丰产稳产,同时有效控制树冠扩张,缓解密植枣园树冠郁闭的问题。喷施赤霉素和加强肥水管理是夏剪技术的必要配套措施。
From 2007 to 2010, we conducted a survey on the Zanhuang Jujube Demonstration Park in Hanixqia village, Aizu, Xinjiang. The key technique of high yield in this garden is to erase newly formed jujube dates from early May to late July Head; in summer in a small amount of retention of the newborn jujube head, secondary branches and jujube stocks pumping jujube hanging and lignified date hanging in mind. Summer shears can significantly improve the yield and quality of jujube trees, to achieve high yield and stability, while effectively control the crown expansion, ease canopy density close canopy problems. Spraying gibberellin and strengthening fertilizer and water management are necessary supporting measures for summer cutting technology.
