1 Open the tree between the layers of light Red Fuji apple tree is very happy, full fruit and early fruit must be open between the tree layers of light, so that the glaze shines from the layers into the inner chamber. If the light is insufficient, it not only affects the fruit quality of the year, but also affects the flower bud differentiation and the output in the coming year. Therefore, we must open the floor, open a good "side window", so that light into the lower inner cocoons, so that branches and leaves evenly bathed. In the fruit orchard, the first layer spacing is increased. Generally, the distance between the main branch of the first layer and the main branch of the second layer is 1.2-1.4m, and the distance between the second layer and the third layer is 1m. At the same time, in the early stage of the growth results, the reserved inter-level subsidiary branches and temporary result branches will be gradually removed or retracted. The auxiliary branches in the south must be left or not to be left, and the auxiliary branches in the north must be small and small, and the south side must be sparse and the north should shrink. Do not leave piles when thinning, and it is rare to eliminate the erect branches on the back of the lower branches. When retracting, it is reduced to the branch after the branch. The year of sparse, heavy weight, and young young seedlings are slow. This will not reduce production, but it will also be able to overcome the size and size of the year. The tree tendencies will not be easy to fight against, and it will also maintain its doctrine of moderation.
2 Controlling Tree Height Red Fuji apple full fruit growth in the initial period of the tree is still very large, the height of the tree is higher, falling head to control the height of the tree according to the tree vigor. The moderate tree tends to be weak, and can fall in place; the tree potential is moderately strong, and can be put in place in the next year, or the first to throw in the flower to reduce the situation, and appropriate thinning, and then fall gradually in 1 to 2 years , Falling head should be selected in the flat branches; Pang Wang tree can be considered in the growing season of 7 ~ August to fall head, one step in place. Generally, the height of the tree is controlled to be about 3/4 of the row spacing, which not only ensures light transmission but also does not make the tree return to prosperous. After the height of the tree is controlled, the sunlight can be directly irradiated from the upper part, so that the tree body can achieve the effect of ventilation and light transmission.
3 Leave a reasonable amount of canopy distance. The widespread closure of apples in Aksu region can be resolved by means of retraction, branching, crowning, falling, bracing, and summer pruning. This allows for reasonable spacing between canopy trees and opening space. Avoid too many branches (forks) between the rows of fruit trees, the excessive transfer of branches caused the closure of the entire park, not only can not be managed under the tree, but also seriously affect the air and light transmission. A small number of shoots are allowed to transfer among the plants, but too many shoots can also cause light to be affected by the closure of the trees. This will eventually result in weak growth of the lower branches, poor quality of the flower buds, and small and poorly colored fruits. The average line spacing is about 1.0m, and the spacing between plants is 0.5m or more. Branches that cross or branch beyond are to be retracted to the more gentle branches, outward extensions of the branches, combined, control the crown. If the tree vigor is more prosperous, it should be noted that it can be dumped in winter and retracted in summer and autumn.
In order to increase the amount of branches for the Fuji tree saplings, the four branch groups were cultured and treated in order to increase the canopy's timely results, leaving as many branches as possible and dumping the branches. The densely-closed branches, rounded stems, convoluted shoots, cross-branched branches, drooping branches and skirts at the lower part of the canopy, which were left in the early stage, will seriously affect the ventilation and light transmission of the trees, and should be eliminated step by step. As a result of compact groups that do not overlap and do not affect each other. Into the fruit tree, you need to control the amount of branches, otherwise ventilation through the poor, reduce production and quality.
5 Strengthen the fruit tree during summer pruning, summer pruning is mainly to pull branches and thin branches. The branch is mainly used to open the angle between the tip angle and the upper branch. The branch that regains the winter branch must be removed or retracted. At the same time, the excessive branching of the competing branches, leggy branches, and peripheral branches should be eliminated to enhance the ventilation. Light. Branches can be removed in the early autumn to ensure the light of the fruit and increase the color of the fruit.
6 Picking leaves has a direct impact on fruit coloring. Picking leaves can be divided into two parts: the first time is 30 to 40 days before fruit picking. The leaves of the fruit on the concealed fruit and the leaves of the neighboring fruit are removed, accounting for approximately 10 ~ 15% of the amount of leaves, leave the leaf blade when picking leaves; the second leaf is generally around October 15, can be removed from the entire tree 35 ~ 50% of the leaves. By picking the leaves twice, it will not affect the differentiation of flower buds in the same year, nor will it affect the tree vigor. At the same time, it will increase the light transmittance of the entire tree, which will lay an excellent foundation for the production of high-quality whole red fruits.
