测定果型指数和灰枣单果重，如果样本量大会耗费很长的时间进行测定，如何提高测定效率是需要解决的问题。为了提高红枣灌溉试验中枣果果型指数及单果重测定工作效率，建立基于枣果体积的南疆灰枣单果重的简易估算方法。以新疆阿克苏的9年生灰枣树的果实为试材，在通过与排水法实测单果体积的比较，确定较为适宜的单果体积估算模型基础之上，采用统计回归方法得到了灰枣单果重与灰枣体积的回归方程。灰枣果实单果重与果实体积之间呈现一元线性函数关系，相关系数为0．9753，在显著性水平α＝0．05下的差异性检验表明，用所得估算公式估算的灰枣单果重与实测结果之间无明显差异。所得估算公式具有较高的估算精度，可以用于灰枣单果重的估算。

It takes a long time to measure the fruit shape index and single fruit weight of gray jujubes if there is a large number of samples .So the problem of how to increase the measuring efficiency is needed to be solved .In order to im-prove the working efficiency for measuring fruit shape index and single fruit weight in the red jujube irrigation experiment , a simple estimation method was established for single fruit weight of gray jujube in southern Xinjiang based on fruit vol-ume .The fruits from nine years old gray jujube trees were chosen as test materials ,through the comparison of fruit vol-ume measured by drainage method ,the appropriate estimation model for the single fruit volume was determined ,and the regression equation between single fruit weight and its volume was obtained using the statistical regression method .The relation between single fruit weight and its volume presented a linear function ,the correlation coefficient was 0 .9753 . There was no significant difference for the single fruit weight between the estimated values by the formula and the mea-sured results under the differential test of significance level α=5% .Therefore the estimation formula possesses high ac-curacy ,and it can be used to estimate the single fruit weight of gray jujubes .
