温室灵武长枣枣头摘心研究

摘要

枣头摘心是枣树栽培管理中的一项重要技术措施。温室栽培灵武长枣枣头摘心试验结果表明：温室栽培灵武长枣时,生长季二级摘心效果最佳,3月中下旬至4月上旬枣头留5￣6个二次枝,7￣10 d后二次枝留6￣8节摘心,单株产量提高144.35%。%Pinching jujube heads is an Important technical measures in jujube cultivation management.The result of a test of pinching jujube heads of Lingwu long jujube cultivated in greenhouse showed that the effect of level two topping in growing season was best for Lingwu long jujube cultivated in greenhouse.The yield per plant increased by 144.35% when 5-6 secondary branches were kept at jujube heads during the time from middle and late March to early April and 7-10days after that 6-8 knots were kept on secondary branches and pinching jujube heads.
