When the apple tree was in the New Year, the fruit quantity was much, nutrient consumption was much, the reserve nutrients of the tree body was reduced, and the flower bud differentiation time was later, the differentiation rate was slow, the quantity was also small, and the development was not perfect, so the second year became Small year. According to this feature, when winter pruning of apple trees after the New Year is completed, due to the small number of flower buds formed in the year, some flower buds and even secondary flower buds should be retained as much as possible. In order to prevent erroneous cutting of flower buds, the time for winter pruning may be postponed, and when the leaves or flower buds can be clearly discerned in the second spring, pruning will be carried out to increase the output of the young year. At the same time, it is necessary to cut short some of the middle and short branches to promote branching and increase the total number of branches and leaves of the whole tree so that the number of flower buds formed in the young apple trees will not be excessive. In the early years of apple trees, the number of results is small, the early growth is weak, and the consumption of nutrients is not much. In the middle and later periods, due to the accumulation of reserve nutrients in the tree, the flower buds differentiate early, and the differentiation rate is fast. Too much. According to this feature, in the winter pruning of the young tree, in addition to the amount of flowers needed to keep enough, the remaining branches should be carefully processed, that is, on the middle, long fruit branches and some short fruit branches, can be cut off the top The flower buds are made into vegetative shoots, and part of the medium and short vegetative shoots are put slowly in order to form flower buds for the second year results. For the branches around the canopy, they can be heavier and shorter at the full site, and properly removed at the time of overcrowding so that there will be a good growth in the next year. For orchards that already have large and small annual results, in addition to using pruning techniques for adjustment, comprehensive management of soil, fertilizer, and water should be strengthened, and fruit thinning and fruit thinning should be conducted in a timely manner. In the year of the year, available nitrogen fertilizers can be topdressed immediately before flower bud differentiation. Promote flower bud differentiation in the year and increase the output of the young year. In the early years, appropriate amounts of available nitrogen fertilizer should be applied in the early spring to increase the fruit setting rate and increase the current year's output. In this way, after 3 to 5 years of comprehensive management, it will return to normal. radiopaque adhesive tape,Radiopaque Tape,Medical Tape Anesthesia Medical Co., Ltd. , https://www.jssinoanesthesias.com
