枣树花芽当年形成、当年分化,随生长随分化、分化量大,枣吊生长、花芽分化、开花座果及幼果发育同时进行,各物候期严重重叠,营养消耗多,各器官对养分竞争剧烈。这是造成座果率低的重要原因。因此,提高枣座果率的根本措施就是加强土肥水管理,改善树体的营养状况。在此基础上,加强花期管理,调节树 Jujube flower buds were formed in the same year, then differentiated, with the growth with differentiation, differentiation, jujube growth, flower bud differentiation, flowering fruit and young fruit development at the same time, the serious overlap of phenology, nutrition and more consumption of organs to nutrient competition severe. This is an important reason for the low fruit set rate. Therefore, the fundamental measure to improve the fruit rate of jujube is to strengthen soil and water management, improve the nutritional status of the tree. On this basis, to strengthen the flowering management, regulation tree
