枣树花期长,开花多,养分消耗大,如管理不当,会造成大量落花落果,从而导致减产。因此,在枣树花期进行保花保果,能显著提高产量,应采取以下管理措施。一、叶面喷肥。在初花期用0．3%～0．5%的尿素溶液进行叶面喷施,以提高花蕾分化质量。在盛花期和幼果期,用0．3%的尿素溶液和0．4%的磷酸二氢钾溶液的混合液进行叶面喷施,能减少落花落果,提高坐果率,增加单果重。二、喷施生长调节剂和微量元素。盛花期喷施浓
Jujube flowering period, more flowering, nutrient consumption, such as improper management, will result in a large number of falling flowers, resulting in reduced production. Therefore, flower jujube flowering Paul fruit, can significantly improve the yield, should take the following management measures. First, foliar fertilizer. In early flowering with 0.3% ~ 0.5% urea solution foliar spray, in order to improve bud quality. In full flowering and young fruit stage, 0.3% urea solution and 0.4% potassium dihydrogen phosphate solution for foliar spraying, can reduce the drop fruit, improve fruit set rate and increase fruit weight. Second, spray growth regulators and trace elements. Blooming spray thick
