枣树的结果、产量高低、品质好坏主要取决于开花坐果期的管理。如果此期肥水供应不足、修剪不到位、通风透光条件差、授粉不良,遭遇干热风、沙尘暴等不良气候条件,均会造成落花落果严重,自然座果率较低,导致枣树大幅度减产。因此,加强枣树此期管理是提高坐果率和品质的关键措施之一。1花前管理一般于5月25日左右追肥,以速效氮肥和适量磷肥为主,结果树施入尿素0.25～0.35kg/株、磷酸二氢铵0.3～0.5kg/株。施肥后及时灌水、中耕除草、松土保墒,保持花期土壤湿润,提高座果率,增 Jujube results, the level of production, quality is good or bad depends mainly on the flowering and fruit-setting management. If this period of inadequate supply of fertilizers, pruning is not in place, poor ventilation and light conditions, pollination, suffered dry hot wind, sandstorms and other adverse weather conditions, will result in serious falling rag, natural fruit set rate is low, resulting in a substantial cut Jujube . Therefore, to strengthen the management of jujube tree is one of the key measures to improve fruit setting rate and quality. A prenatal management generally top-dressing on May 25 to quick-acting nitrogen fertilizer and appropriate amount of phosphate-based fertilizer, the results of the tree into the urea 0.25 ~ 0.35kg / strain, ammonium dihydrogen phosphate 0.3 ~ 0.5kg / strain. Timely irrigation after fertilization, cultivating weeds, soil moisture, maintain flowering soil moisture, increase the rate of fruit set by
