在枣树萌芽前和第一次生理落果用前施肥，能显著提高枣花数、枣花座果数和７月份以后的存果数，但不同施肥量之间效果有显著差异。施肥改善了内源激素的合成条件，但对不同时期效果不一样。在初花期和第一次生理落果期前喷施外源激素，在短期内改变了内源激素的平衡，影响了枣花座果。以１０５浓度的ＧＡ３喷施提高枣花座果的效果最为显著，ＧＡ３和ＩＡＡ混合项应效果最差。
Before jujube germination and the first physiological drop fruit fertilization can significantly increase the number of jujube, jujube fruit number and the number of fruits after July, but the effect of different fertilizers were significantly different. Fertilization improved the synthesis of endogenous hormones, but the effect is not the same for different periods. Spraying exogenous hormones at the beginning of flowering and the first physiological decolonization changed the balance of endogenous hormones in the short term and affected the fruiting bodies of jujube. Spraying with GA3 at a concentration of 105 was the most effective way to increase the fruit size of Zizyphus Jujuba, GA3 and IAA mixed items should be the worst.
