After the apple enters the full fruit period, the target of production is different from the sapling period and the early fruit period. The task of pruning has undergone a fundamental change. In the specific pruning, the strain should be changed and the pruning should be well done. According to our experience, after entering the fruit period, Apple should make the following four changes when pruning, in order to facilitate high yield, stable production, and high quality. 1 Tree transformation Qiaohua apple orchard is mainly produced by free spindle and improved spindle shaping. In order to increase branching and increase accumulation of photosynthetic products in the sapling stage and early fruiting stage, more branches are left, and each plant remains. The branch axis is more than 10; after entering the full fruit period, canopy closure is likely to occur, leading to deterioration of the light in the canopy, which is not conducive to the improvement of yield and quality. The improvement of the ventilation and light transmission conditions in production, the optimization of the ability to form the results of intrinsic flowering, and the implementation of a full range of results have become one of the main objectives of management in production. During production, the headlights are used to increase the top light; by removing the large branches of the trunk, the layers of the branches are pulled open to increase the amount of side light; and the utilization of the reflected light is increased by sawing off the low branches to dry them. With the implementation of comprehensive measures, the tree shape applied in apple production has changed, that is, from the spindle shape to the happy shape. The happy shape has less total branches and sufficient light energy. After the fruit period, the use of happy shape is conducive to high yield, stable production, and high quality, which is the main tree of the orchard application in the full fruit period. With the increase of the age, it is necessary to gradually reduce the amount of large branches, and eventually each tree can maintain 3 to 4 branches. 2 pruning method from increasing the amount of branches to control the amount of branches The outstanding problem in the production of saplings is that the number of branches is small. Therefore, increasing the number of branches becomes the main task of management. In pruning, light cutting is recommended to keep branches; and after entering the fruit period, the problem that emerges is that the field is closed and the branches are over. Large, leading to poor ventilation and light transmission, thus reducing the amount of branches will become the main task of management, through the application of methods to control 667 m2 branches in about 80,000 to ensure that the park has good permeability. When sparsely branching, it should be emphasized on the removal of dense branches, overlapping branches, cross branches, and branches, round branches, multiple branches, opposite branches, diseased branches, and branches with a roughness greater than 1/3 of that of the mother branches. 3 The leaf curtain layer is thick and thin In the sapling period, with the formation of the canopy, the leaf curtain layer gradually thickens, and after entering the full fruit period, due to the thickening of the leaf curtain layer, the light does not enter, it will lead to deterioration of the crown canopy, poor canopy and lower part of the canopy, Poor flowering ability will turn into an ineffective growth area, which is not conducive to the improvement of output and efficiency. Therefore, after entering the fruit period, it is necessary to artificially make the leaf curtain thin to optimize the ventilation and light transmission conditions. The method for promoting the thinning of the leaf curtain layer is mainly to remove the large branches on the stem, through the sparse branches, open the layers, change the layer of the leaf curtain to a multi-layered leaf curtain, and enhance the ventilation and light transmission. 4 Result Branch changes from old branch to new branch The transition of apple trees from the sapling stage to the fruit stage is the process of gradual formation, utilization, and aging of the resulting branches. After entering the full fruit period, a large number of the results of the aging of the branches, the ability to decline, so after entering the full fruit period, we must pay attention to strengthen the results of the renewal of the branches in order to maintain a strong growth of the results. In the apple tree body, generally the thick branches of the cigarettes to the thumb have the ability to produce results, but the thickness of the branches is different, and the resulting quality is different. Generally, there are many nutrients accumulated in the thick branches, resulting in large results and high quality, while thin branches are difficult to bear. Therefore, we must eliminate the thin and weak branches that have changed over the years. We must pay attention to selecting the remaining branches to be cultivated in order to replace them before preparing thinning branches. Generally, apple branches from 2 to 7 years old have the ability to produce flowers. However, the branches of different branches have different results. Among them, the branches with 2 to 5 years of age have the best quality, and the branches with 5 years or more are the best. As a result, there was a decline in the ability to produce results. Therefore, after entering the full fruit period, the results should be updated in batches each year in batches to maintain the results of strong branch, improve the ability to tree solidification. 18Mm Utility Knife,Auto-Lock Utility Knife Cutter,Professional 18Mm Utility Knife,Stainless Steel Utility Knife Shangqiu City Huashang Zhiyuan Tools Co., Ltd. , https://www.hszytools.com
