摘要: 研究枣股和枣吊的生长发育规律,在生产中采取对应的技术措施加强枣园管理以提高枣子产量。采用随机抽样方法调查统计栽培于延川县红枣主产区的24个枣树品种(系)的枣股粗度和长度,及枣股上枣吊数、枣吊长度、枣吊叶片数、挂果数等农艺性状,结合实验室分析研究其生长发育规律。阐明了枣股长、枣股粗、枣股形态、枣吊长、枣吊叶片数、挂果数与枣股龄的相互关系,揭示出它们的生长发育规律。品种间枣股和枣吊生长的变异大于枣股龄间。提出基于枣股龄基础上的生长发育曲线将枣股生长发育划分为5个时期的标准;基于枣吊的某些生物学性状与有效挂果数的相关系数,首次建立了高产枣树品种选择的综合指数;提供了丰产枣园枣股管理的科学依据和针对性措施。

Abstract: The research aims to study the growth and development law of jujube fruiting sections and jujube's fruit bearing shoot, and take corresponding technical measures to strengthen the management of jujube orchard in order to improve the yield of jujube. The authors used random sampling method to survey statistics thickness and length of jujube fruiting sections and germinated jujube’s fruit bearing shoot number, length, leaf number and fruiting number in the jujube fruiting sections of 24 jujube varieties (lines) cultivated in Yanchuan jujube producing areas, and combined with laboratory analysis, studied the growth and development law of jujube fruiting sections and jujube’s fruit bearing shoot. The results clarified that thickness, length and shape of jujube fruiting sections and length and leaf number and fruiting number of jujube’s fruit bearing shoot had certain relationship with jujube fruiting section age and revealed their law of growth and development. Intervarietal variation of jujube fruiting sections and jujube’s fruit bearing shoot growth was greater than that between ages of jujube fruiting sections. The authors proposed that the growth and development curve based on jujube fruiting sections could be used to divide the growth and development into 5 phases, and established for the first time the comprehensive index for selecting high yielding varieties of Chinese jujube on the basis of the correlation between some biological character and the effective fruiting. The study provided a scientific basis and practical measures of jujube fruiting sections management for high yield jujube orchard.
