对多年生不修剪的大欧李树单株结果情况进行了调查分析，结果表明株丛内结果枝多少是产量构成的基本因素；发现了株丛内基生果枝和侧生果枝的多少随树龄的变化而不同，４年生以上树的基生果枝减少，侧生果枝增多，并且逐渐成为株丛内的主要结果枝；果枝结果的多少是单株产量的保证。发现了节位座果数是果枝结果多少的主要构成因素之一。调查表明果枝粗度大、节位座果高、果枝长度大的株产量就高，它们是构成果枝产量的３个重要组成部分。这多个部分之间是可以通过修剪转化的。基生果枝生长势强，平均座果高。侧生果枝生长势弱，平均座果率低。提出了提高果枝座果数和提高株产的建议。
The perennial uncut pruning large monocots results were investigated and analyzed, the results show that the number of fruiting branches within the plexus is the basic factor in the yield composition; found within the plantlets within the fruit branch and the number of fruiting branches with the tree age Changes and different, more than 4-year-old fruit tree branches to reduce the number of fruiting branches increased, and gradually become the main result within the plant branches; fruiting branches of the results is how much is the yield per plant. It was found that the number of sessile fruits is one of the major components of the fruiting branch results. Surveys show that fruit branches are large in size, with high fruit positions at the node and high strains of fruit branches, which are the three major components that make up the fruiting branch. These multiple parts can be transformed by pruning. Basal fruiting branches grow strong, the average fruit height. Lateral fruiting branches grow weak, the average fruit set rate is low. Proposed to improve the number of fruiting branches and improve plant production recommendations.
