Big Cherry Summer Trim Tips

Cherry summer pruning is best carried out after harvesting branches have not been fully lignified, the main method is to pull branches, topping, cutting tip, thin branches, girdling and so on. 1, pull the sticks. Pruning in winter does not solve the air and light conditions of the tree at one time. Some trees, such as over-emphasizing the angle during winter cutting, will inevitably need to be cut off, causing unnecessary losses to the tree. In the summer, it can solve the problems that can not be solved by winter shears, so as to reduce the amount of branching. At this time, the branches are pulled, the tree body reaction is mild, the back is not easy to take, and the main branches and lateral branches of the branches are 60-70 degrees. Should be, other branches can be pulled 80-90 degrees. 2, topping and cutting tip. Topping refers to removing the young part of the tip of the new shoot before it has hardened. The topping of the big cherry juvenile tree has the functions of controlling the growth of shoots, increasing the number of branches and branches, promoting the transformation of branches, and accelerating the expansion of the crown, which can save nutrients, promote flower bud formation, and increase fruit yield and quality. Cutting is the cutting of a portion of a new shoot, mainly when the shoot has been unable to pick up or to expand the canopy. Because the trimming is greater than topping, its function is also stronger than topping. 3. Thinning. In summer, thinning is generally performed after fruit picking. The purpose is to eliminate perennial branches that are too dense and strong to seriously affect the light, so as to improve the ventilation and light transmission conditions of the canopy, balance the tree potential, and cut wounds after harvesting. It's easy, it's lighter on the tree. 4, girdling. The girdling of large cherry trees can promote the formation of flower buds and increase the fruit setting rate and fruit quality. The effect of improving the hardness and sugar content of the flesh is especially obvious, but after the large cherry tree is girdled, the wound healing is slower. Note that the girdling width should not exceed 0.5cm, and due to the different tree vigor of the cherry, especially the trees with less organic fertilizer, it is prone to flow-glue phenomenon, so it should be used with caution in production and accumulate certain experience before application.
