摘　　要：[目的]探讨‘费尔杜德’1年、2年生枝和‘海尔特兹’1年生枝的留枝密度对生长发育及产量的影响。[方法]以自然生长枝（不修剪）为对照,研究‘费尔杜德’1年生枝每667 m2留枝量为2 550~2 600、2 050~2 100、1 550~1 600枝、2年生枝留枝量为2 450~2 500、1 950~2 000、1 450~1 500枝和‘海尔特兹’1年生枝留枝量为5 950~6 000、4 950~5 000、3 950~4 000枝,对枝条生长、果枝数、结果数、平均果重、单株产量及666.7㎡产量的影响情况。[结果]结果表明,‘费尔杜德’和‘海尔特兹’666.7m2留枝量分别为2 450~2 500和5 950~6 000枝,产量和经济效益为最高,较对照分别增加45.7%、63.5%和40.7%、54.0%。[结论]单位面积适宜的结果枝种群密度可有效促进枝条生长,产量和经济效益明显增加。[Objective] The aim of present study is to analyze the effect of annual and biennial branches density on growth and yield of cultivar ＇ Fertod Zamatos＇ and ＇ Heritage＇. [Method] With natural branches （without pruning） as the control, annual branches density from 2 550 to 2 600, 2 050 to 2 100, and 1 550 to 1 600 per an 667 m2 of ＇ Fertod Zamatos＇, from 5 950 to 6 000, 4 950 to 5 000, and 3 950 to 4 000 of ＇ Heritage＇, and biennial branches density from 2 450 to 2 500, l 950 to 2 000 and 1 450 to 1 500 of ＇Fertod Zamatos＇, to analyzed the effects of the branches density on branch growth, number of fruit branches and fruit setting, average weight, yield per plant and 667 m2. [Results] The results showed that the reserved branches of ＇ Fertod Zamatos＇ between 2 450 to 2 500, and ＇Heritage＇ between 5 950 to 6 000 per an 667 m2 could with the highest yield and economic benefit, among of them, the yield increased by 45.7% and 63.5%, economic benefit increased by 40.7% and 54.0% than control, respectively. [Conclusion] Suitable fruit population density per unit area can effectively promote the growth of branches, and obviously increase the yield and economic benefit.
