Litchi bar is thin, with low water content, such as trimming prematurely, cutting the mouth is easy to lose water and dry, not easy to heal. Therefore, pruning should be completed before the sap begins to flow, and the principle of early shearing of old and weak trees and late shearing of weak trees should be mastered. The eucalyptus forms are naturally happy, semicircular and conical. The first two are suitable for planting plants with a spacing of 1.52 meters, and the latter one is suitable for planting more than 300 plants per 667 square meters. Pruning methods are as follows: First, the branches should first cut off the dead branches, the branches of the pests, the wounded branches, the acupuncture branches and the branches, and then cut the dense branches. When thinning the result branches, first go to the branches, the branches, the lower branches, and the thin and weak branches; then go to the upper branch and the middle branch; if it is still dense, then loosen the two branches, and cut the distance between the fruit branches to 5-6 cm. Both are full-grown and powerful white sticks. Second, deal with the leggy branches of leggy branches growing at the branches of the branches of the branches, as the extension branches of the branches, and appropriate truncated, so that the branching potential and direction of extension is stable; there are spaces near the leggy branches, appropriate short cuts, training results Branches, enlarge the crown, increase the area of ​​the result; leggy branches without use value, cut off from the base. Third, update the results of the rejuvenation of the branches and branches results in the branches of the fruit after 2 years of fruit more than sagging, the ability to reduce the results, the results of the branches, leaving 3 to 5 cm short cut, after the spring sprout, choose a growth direction is appropriate and Robust buds are cultivated into new fruit trees through topping. Fourth, update the results of the results of the branch Zhi Zhi results due to different varieties of different fruit ability, some can be continuous fruit for two seasons, and some can only end a season fruit, or only small fruit at the top of the knot. The result was that the weak fruit branches were characterized by gray-brown branches and very short branches. The fruit branch must be updated shortly. Generally cut from the fruit branches bent drooping, sturdy short shear 1/2, weak short cut 2/3, too weak to leave only 5 to 6 cm short cut, short-cut degree rather light rather than heavy.
