一、合理施用肥水对3～4年生的幼树,6月份一定要控水、控氮肥,增磷补钾。叶面喷施光合微肥、0.5%的尿素液以及0.4～0.5%的磷酸二氢钾液。二、适时拉枝、扭梢和环剥于麦收前后,对角度小的骨干枝、辅养枝进行拉枝:骨干枝基角拉成60～70度,辅养枝拉成水平或下垂,拉枝时要选好着力点,防止折断。对较粗的辅养枝于基部实行环剥(切),剥口宽度 First, the rational use of fertilizer on the 3 to 4-year-old saplings, in June must control the water, control of nitrogen, increased potassium. Foliar photosynthetic fertilizer, 0.5% urea solution and 0.4 to 0.5% potassium dihydrogen phosphate solution. Second, timely pull branches, twist tip and ring peel before and after the close of the wheat, the small angle of the backbone of the branch, supporting the branches to pull branches: bone branches angle pull 60 to 70 degrees, supporting branches pulled into the level or drooping, pulling Branches to choose the best focus to prevent breaking. Roughly nourish branches at the base of the implementation of girdling (cut), stripping width
