每当枣花散发诱人芳香的季节,人们在枣树主干距地面二三十厘米处,用刀剥去三五厘米宽的一圈皮层,叫做“开甲”,经过开甲的枣树,能增产50～70％。在苹果树旺盛生长的五六月份,对幼旺树上的辅养枝,于基部用环剥刀割去一圈相当于枝粗直径1/8～1/10宽的皮层。可促进当年枝条上部的花芽形成,为下一年大量结果打下基础。这种增产措施称为“环状剥皮”。落花落果严重的“红星”苹果树,如在花期进行“环状剥皮”,可提高坐果率两倍入伏后,某些地区习惯于对低产的梨树主干进行大扒皮,到落叶越冬前可全部形成新皮,全树当年能形成大量花芽,次年结果量显著增加。
When jujube flowers exudes attractive aroma season, people in the jujube trunk from the ground twenty or thirty centimeters, with a knife stripped thirty-five centimeters wide circle of cortex, called “open armor”, after the open jujube, Can increase 50 to 70%. May or June in the vigorous growth of the apple tree, the young branch tree on the maintenance branch, at the base with a ring cutter to cut a circle equivalent to the branch diameter 1/8 ~ 1/10 wide cortex. It can promote the flower bud formation in the upper part of the branches of the year and lay a foundation for a great deal of results in the following year. This increase in production is called “ring peeling.” If the “red star” apple tree with falling plum blossom is “ring-shaped peeled” during florescence, the fruit setting rate will be doubled. After some areas become accustomed to performing large-scale peel on the low-yield pear tree trunk before deciduous wintering The formation of a new skin, the whole tree that year to form a large number of flower buds, the following year a significant increase in the amount of results.
