In order to adapt to the requirements for cultivation of fruit trees (apples, pears) that are short, dense, early, and abundant, the following methods of pruning should be used when pruning fruit trees: 1. Curved and bent branches. When the fruit trees are planted, do not cut off the upper part to pull the shears, pull the part above the fixed height to a nearly horizontal shape, 50 centimeters from the ground, a 20-degree angle with the horizon, and a 45-degree angle with the direction. In this way, branches can be avoided after gardening, which is conducive to farming. For the leggy branches on the back, they are also pulled to a nearly horizontal shape at the angle of the curve. This method can increase the amount of branches and can also be seen as an early result, leading to the emergence of branchlets on adult large branches and the formation of more flower buds. 2. Curve dry on both sides. The "upwardness" of sprouting of fruit trees is that on each trunk and main branch, there are many buds sprouting on the horizontal surface and less buds on the downward surface. In order to increase the germination rate of fruit trees and increase the amount of foliage, from the beginning of fruit tree colonization, the method of bending and drying on both sides was adopted. After the annual grafted seedlings were planted, when the top buds germinated in early spring, the seedlings were bent at a constant height (50 cm above the ground). At a 20-degree angle from the horizon, forming a 45-degree angle with the direction of the line. When the bud on the back reaches 5 centimeters when the new shoot sprouts, the stem will be lifted up, and will be in the opposite direction. Pull into the second bow. The buds on the back of the bud will sprout 6-9 cm from the new shoot, and will be lifted up again to return to the position of the first bow, and will remain fixed as the main branch of the first layer. When the second branch is pulled early in the next year, it is treated as such. In the 3rd, 4th, and 5th years, the same thing is done. In this way, the main branches can be sprouted on the top and bottom of each layer, which can significantly increase the amount of branches and leaves, laying the foundation for early fruit production. 3. Skillfully used to injure. The transportation of nutrients in deciduous fruit trees can be divided into two situations: (1) When the trees are defoliated and dormancy is completed, when germination occurs in early spring, nutrient supply stored in the body is mainly germinated. Since the backbone, main branches, and roots store a lot of nutrients, we can treat it simply as nutrients that are transported "from the bottom up." (2) When the branches of fruit are pumped, the functional leaves are fully grown, photosynthetic products can be produced, and other parts of the tree can be supplied, its nutrients are transported "from the top down." The principle of scratching is to block the transport of nutrients and transport them to the parts and areas that we need to germinate to promote flowering results. Therefore, when the deciduous fruit trees are in the period of nutrient "from the bottom to the top" of the transportation period, injuring the top of the buds can promote better germination, and the branches that are pumped grow rapidly. Similarly, when the nutrients of fruit trees are transported from top to bottom, they must be wounded under the shoots in order to promote better and faster sprouting of the shoots. In this way, it is also the method of injuring wounds, choosing different periods, different locations, and There is a trick. 4. "Remedy" for the death of a formed fruit tree center. Production often occurs in the center of the fruit trees that are forming or die, or the fruit trees in the plastic surgery are still dead. The common practice is to cut off the sick and dead center and use the new shoots that germinate under the wound to grow the center stem. This not only slows the forming but also affects the upper yield of the tree. In production practice, we have adopted new methods in fruit trees such as Red Fuji and Red Star Apple. Before germinating in the spring, we will pull up strong lateral branches and use ropes to dry them to the sick and death center as a new centerpiece. When the rope is fixed, the sick and dead center should be wrapped in plastic cloth, and at the same time, the worn bicycle tire should be placed between the rope and the branch so as not to injure the bark, and then a small lateral branch with suitable position is selected as the new lateral branch in the center. After the new trunk was fixed in September of that year, the rope was released and the dead center was sawn off. Afterwards, the pruning method was the same as that of other fruit trees in the same park.
