It was found in production that the densely planted red Fuji apple orchard that had been developed in previous years had poorly managed tree roots, which caused the crowns to be tall, large, and densely connected. The problems of orchard closure, ventilation, and poor light transmission have become increasingly prominent, affecting fruit yield and quality. In such an orchard, in addition to the use of open angle, ring peeling and other means to ease the main branch and auxiliary branches to open the light path, the central leadership should also pay attention to the height control and fall. The specific technology is: 1. In the early stage of the results-control method, when the lower-level backbone branches have been matched and the tree is about 2 meters high, the center leader must be asked to "swing his head once a year" to control its growth. That is, during the winter shearing, remove the strong-growing proto, and choose another oblique branch with a moderate growth as the central branch; next winter, cut another oblique branch in a different direction as the central branch, so that the center stem is slightly Bend upwards. This not only eases the upward growth of the central trunk and effectively controls the height, but also helps to equip the upper backbone branches and permanent infusion branches to prevent the upward and downward weakness in the early stage. 2. In the middle period, the fruit crown method was used to reach the full fruit period. When the tree was about 3.5 meters high, before the early spring germination, the center stem of the red Fuji apple tree was pulled to the side with a rope at an angle of about 85 degrees. Wipe off the back buds in time after germination. If the pulled branch grows stronger, it can be used in conjunction with ring peeling, ring cutting and other methods to make vegetative growth transform to reproductive growth as soon as possible to achieve fruit crown. The number of fruits remaining on the top of the center stem depends on the strength of the growth. The strength is more, the weaker is less or not. Generally, the ratio of branch to fruit is 7-10: 1, and the single fruit is mainly on each inflorescence. . 3. The top of the central stem after falling flat in the late stage will be turned into a low-hanging and weak branch due to the continuous years of results. At this time, you can do the U-turn during the winter shear, that is, to dry out the original center or Retract. In the previous year, the purpose is to choose another long branch or auxiliary branch to cultivate instead of the original head. Repeat the steps of "pressing the crown with fruit-falling head and changing head" many times to maintain the crown. At a certain height, avoid the phenomenon of center running and parachuting.
