摘　　要： 对8 a生的红枣新梢干物质累积量与新梢总叶面积、总叶片数、长度、径粗及体积进行了实测并进行了统计分析。结果表明,新梢干物质累积量与新梢总叶面积、总叶片数、长度及径粗具有显著相关的多重线性回归关系,且新梢径粗和径长是影响干物质累积量的主要指标;新梢干物质累积量与新梢径粗和体积间存在高度正相关回归关系,并且乘幂方程的相关性最好;分别利用新梢径粗和体积计算得到干物质累积量没有显著差异(α=0.05),建议实际测定时,以新梢径粗为参数的乘幂方程来测定新梢的干物质累积量。 The dry matter accumulation amount,total leaf area,leaf number,length,diameter and volume of new shoots were measured and statistically analyzed for eight-year-old jujube trees.The results show that the dry matter accumulation amount,total leaf area,leaf number,length and diameter of new shoots are all significantly related in the relationship of multiple linear regression,and the length and diameter are the main influencing factors of the dry matter accumulation amount.The dry matter accumulation amount is significantly correlated with the diameter and volume in the relationship of positive regression,and the power equation is best in correlation.By using the diameter and volume to make calculation,it is obtained that the dry matter accumulation amount has no significant differences（α=0.05）,so it is recommended to practically estimate the dry matter accumulation amount of new shoots by using the power equation in which the measured diameter is a parameter.
