在盛花后１５～３０ｄ对极早熟桃春蕾主枝进行环剥（宽度５～１０ｍｍ），可使果个增大５～１０ｍｍ，果实可溶性固形物含量增加３０％，果实成熟期提前７ｄ左右。发育枝和徒长性果枝比对照减少１０％，并可抑制新梢旺长。
In the 15 ~ 30 days after flowering, the perennial perennial peach ring (5 ~ 10mm in width) could increase the fruit size by 5 ~ 10mm, the content of soluble solids in the fruit increased by 30% and the fruit ripening stage was about 7 days earlier. Developmental branches and apples long fruiting branches than the control reduced by 10%, and can inhibit the proliferation of new shoots.
