每公顷定植1667、2500、3333、5000株的第三年‘Flordazold’桃[Prunuspersica(L.)Batsch],在前一年6月采果后进行顶截的,每公顷产量分别为13.4。24.6、19.7和32.6公吨。而每公顷种植238株不顶截(topping)的,产量只有0.8公吨、顶截高度为0.5米的四种种植密度产量都低于顶截高度为0.75米的。‘Florida 3—4’油桃每公顷的产量分别为5.3、5.4、6.7和9.4、公吨,而不顶截的为0.8公吨。采果后顶截的树,其果实比没有顶截的大。
Flordazold ’peach [Prunuspersica (L.) Batsch], the third year of 1667, 2500, 3333, 5000 colonies per hectare, was top-cut after picking the fruit in June of the previous year and the yields per hectare were 13.4.24.6 , 19.7 and 32.6 tonnes. While 238 plantations per hectare were not topping, yielding only 0.8 mt, and four plantarities with a top cutoff of 0.5 m were below the cut-off height of 0.75 m. The yield per hectare for ’Florida 3-4’ nectarines was 5.3, 5.4, 6.7 and 9.4, respectively, compared with 0.8 metric tons for non-top cuttings. After picking the tree cut the top of the tree, the fruit is larger than no cut-off.
