拉枝是果树整形修剪的方法之一。但往往由于绳索过细和忘记解除,绳索随着枝条的生长增粗便镶在枝条内,产生很深的沟槽,多年都不易复原。还有些农户为图方便,在房屋附近的果树枝条拉上铁线,用来晾晒衣服,也产生了很深的缢痕。这种缢痕严重影响枝条的输导能力,增加病虫感染的机会。遇上大风大雨或人为弯折及结果多时,极易从缢痕处折断,影响树势和产量。笔者今年暑假在家乡平南就看到了丰产龙眼树由于拉枝造成缢痕而导致枝条折断的现象。补救的方法是:①及时解除拉在枝条上的绳索、铁线,避免缢痕再度加深。②解除拉枝绳索时,发现有缢痕,做好标记,于果树旺盛生长月份,用锋利的刀将沟槽内的皮层切去一圈,沿着沟槽边沿一 Pulling branches is one of the ways to prune fruit trees. However, often due to the rope too thin and forget to lift the rope with the growth of branches will be thick in the branches, resulting in deep grooves, not easy to recover for many years. Still other farmers in order to facilitate the map, in the vicinity of the house on the branches of fruit trees pulled wire, used to dry clothes, but also had a deep scar marks. Such marks seriously affect the ability of shoots to increase the chance of pest infection. In case of heavy rain or artificial bending and the result is long, easily broken from the marks, affecting the tree vigor and yield. This summer I saw in my hometown Pingnan longan trees due to the resulting stretch marks caused by broken branches of the phenomenon of broken branches. Remedy is: ① promptly lift the pull in the branches of the rope, wire, to avoid further deepened marks. ② lift the cable pull rope, found a mark, mark, in the vigorous growth of fruit trees in months, with a sharp knife to cut the cortex in the cortex in a circle, along the groove edge of a
