以成年的马叙葡萄柚,沙莫蒂甜橙和伏令夏橙为试材,用U形刀或环剥刀在切口两侧将木质部与树皮分离。环剥时期分六月初、7月和8月。环剥宽度为2.5和4.0毫米,二重环剥是在第一次环剥三周后,在同一位置重复环剥一窄环。试睑结果表明,环剥最佳时期以六月落果后到七月初为宜,这样可避免增加果实数量,以达到最大限度增加果实体积的目的。环剥宽度的影响看来不一致,在多数情况下,二重环剥比单环剥的效果好。对全树所有主枝进行环剥容易对根造成不利影响,作者主张只环剥全树三分之二的
To adult Mushu grapefruit, Chamoides sweet orange and Vladimir summer orange as the test material, with the U-knife or ring stripping knife on both sides of the cut xylem and bark separation. Galloping period in early June, July and August. Girth width of 2.5 and 4.0 millimeters, double girdling is the first ring girdling three weeks, in the same position repeated girdling a narrow ring. Test eyelid results show that the best period of girdling in June after the beginning of fall to early July is appropriate, so as to avoid increasing the number of fruits in order to achieve the maximum increase in the volume of fruit purposes. The effect of the width of the girdle appears inconsistent, in most cases, the double girdle is better than the single girdle. Girdling all the main branches of the whole tree tends to adversely affect the roots, and the authors advocate that only two-thirds
