Don't make these six mistakes in Apple's summer management

I. Heavy Winter Cutting and Light Summer Cutting
Some fruit growers only pay attention to shaping and pruning, but neglect the management of growing season. As a result, "branches are full of trees, there is no light under the trees, nutrients are wasted, and flowerless trees flourish". Therefore, we must change our concepts and pay equal attention to the management of growing season and winter pruning.

 

2. Lack of attention to proper pruning

The correct pruning method is to adopt eight techniques to promote and control young, vigorous trees, trees with poor illumination conditions and difficult to flower in orchards. Under the premise of improving ventilation, the pruning method should be timely and moderate, rather light than heavy. The principle is not to stimulate the vigorous growth of fruit trees, but not to weaken the tree vigor, and to reduce the loss of branches and leaves, so as to achieve the goal of early flowering and more fruits.


3. Short and Overweight

At present, most fruit trees use uniaxial branch extension, and the twigs on both sides of uniaxial branch are rarely short or not short in summer. Some fruit growers adopt the "push wool" pruning method, either cutting short nutrient branches or cutting whole fruits, or shrinking the branches and breaking the top. This variety of cutting methods will disrupt the nutritional distribution of the whole tree, and eventually lead to dense twigs, which is difficult to ease. In pruning, we should keep small, small, sparse, multi-headed, single-headed, split ring, promote the development of restraining branches, soften the branches, slow down the growth potential of the front-end, turn branches and injure, pick hearts and leaves, increase nutrition accumulation, and never stop short cutting.

  

4. Bare and empty back

Due to the influence of crown tree shape in the previous year, after large modification, quite a number of single axle branches were bare at the back, and there were no twigs, which made the bore empty and not solid. For this kind of branch, besides opening angle, it can promote the germination of branchlets in bare branches, then twist the shoots, pick and defoliate, and cultivate good fruiting branchlets.


5. Too many twigs

After remodeling, some branches are not enough, but some trees have too many branches. For this kind of tree, we should adhere to the pruning principle of "dense branches are not dense, twigs are suitable" in summer pruning. The size of the twigs on both sides should be balanced, the distance should be appropriate, the redundant branches, the same age branches and the upper dorsal branches should be removed, the upper dorsal branches should be extended and the tree shape should be controlled.


6. Diseases and insect pests should be treated seriously, but not prevented seriously

We should actively adhere to the principle of "prevention first, comprehensive prevention and control". We should pay close attention to the occurrence of pests and diseases from Daqing Garden in spring every year to each growth stage, so as to create a good ecological environment for the production of high-quality and high-grade fruits.
