于１９９４—１９９６年，在北京农业大学实验农场（河北·涿州）对“庆丰”和“燕红”桃树（ＰｒｕｎｕｓｐｅｒｓｉｃａＬ．）进行了“长枝修剪”试验，研究了长枝修剪对桃树生育状况的影响。结果表明：和传统的“短枝修剪”树相比较，“长枝修剪”树开花期提前１—２天；早期叶面积形成快，并且在整个生长季节里维持一个较高的叶面积水平；叶片的光合速率得到显著地提高；株产、单果重和果实可溶性固形物的含量有不同程度的增加。
In 1994-1996, the experiment of “long branch pruning” was conducted on “Qingfeng” and “Yanhong” peach trees (Prunus persica L.) at Beijing Agricultural University Experimental Farm (Hebei Pizhou) The impact of fertility status. The results showed that, compared with the traditional “pruning” tree, “pruning” tree flowering stage 1-2 days in advance; early leaf area formation quickly, and in the entire growing season to maintain a high level of leaf area; Photosynthetic rate of leaves was significantly increased; plant yield, fruit weight and fruit soluble solids content increased to varying degrees.
