本文以“五月红”(Mayfire)油桃为试材,分4个时期对主枝进行环剥,以了解环剥对果实和树体的影响.在果实生长Ⅱ期前环剥的植株,其果实生长高峰到来的早,而稍后环剥或不环剥则生长高峰到来的晚.果实生长Ⅱ期前环剥能达到最佳效果,此时核长约10mm.此期环剥使果实增重大约22.5%,大果率明显增多,果实成熟时可溶性固形物增加了42%.早环剥可抑制新梢的延长生长。所有环剥处理增加了单位面积叶重,降低了叶内养分含量.采前8天和采后78天的测定结果表明,环剥对叶片水气输导率(g_1)没有影响,但在采后15天每个环剥处理的 g_1都降低了.
In this paper, the Mayfire nectarines were used as test materials, and the main branches were girdled in four periods to understand the effect of ring-peeling on the fruits and trees. Plants, the peak of its fruit growth come early, and then ring or ring perennial growth peak come late .Globe growth before the first ring to achieve the best results, at this time the nuclear length of about 10mm. So that fruit weight gain of about 22.5%, significantly increased the rate of large fruit, soluble solids increased by 42% of fruit ripening. Early girdling can inhibit the extension of shoot growth. All girdling treatments increased leaf weight per unit area and decreased leaf nutrient content.The results of 8 days before harvest and 78 days after harvest showed that girdling did not affect leaf water vapor conductivity (g_1) The g_1 of each girdling was reduced after 15 days.
