沙棘果实产量与骨干枝、果枝、花序数，花序果密度和果枝果密度等表型数量具有相关关系，可通过抽样调查果密度、果枝密度和百果重3因子估算果产量；以小样本抽样调查果密度和果枝密度，确定果枝和3年枝平均长度是提高调查精度的关键环节；树冠不同方向和部位果枝及果枝上、中、下段的百果重差异很大，应选择半阴面中位果枝，采摘全部果实，随机抽取100粒果称量得百果重。调查估算果产量与剪枝摘果实测果产量的平均误差10%，准确率90%。

Seabuckthorn fruit yields have a great relations to main branches of tree, fruit branches, flower quantities and fruit density. The seabuckthorn yield can be well estimated by 3 factors investiga-tion which are fruit density, density of fruit branches and weight of 100 berries; the fruit density and the density of fruit branches are surveyed by small samples, it is key factor to determine the average length of 3 years branches;it is found that a great difference of berry weight exists on different direc-tion and areas of crown and different location on branch, like tops, middle and lower, so it is a better way to estimate the yield by picking up all the fruits on selected branches which are located on middle of branch and half shadow of crown, and then weighing 100 berries randomly. The average error is within 10% and the accuracy is up to 90%.
