First of all, the purpose of apple tree pulling technique is to artificially shape the apple tree, and the apple tree branch pulling is also to prune the fruit tree and effectively assist the tree shape. Generally, apple tree pulling technology should be more suitable from September, because in autumn, the apple tree branches are soft, not easy to break, first look at the branches of small fruit tree seedlings, the small seedlings will basically grow 3 to 5 branches and main stems, first select 3 branches from the following layer, require the branches to be strong, the angle is moderate, and form the 3 main branches of the fruit tree.
<>Originally, apple trees can pull branches all year round, but the trunk of the branch pulling branches is hard in winter, and it is easy to break the branches, and it will also break the fertilizer and water ducts of the branches, which is prone to leaf disease, and at the same time, the branches are easy to be frost damaged in winter, so they do not pull branches in winter. Spring pull branch opening angle, can only be said to be better than not pulling the branch effect, the angle of small upright branches, oblique branches, if not open the angle, its growth will be stronger, lengthened, thickened, grow very fast, seriously affect the growth of the surrounding branches, resulting in tree potential, branch potential imbalance, disturb the tree shape,.
As an important measure of tree shape transformation, branch pulling can help to promote the formation of young trees, adjust the tree potential and branch potential, alleviate the flowering promotion, improve the light, and improve the fruit quality, which is irreplaceable by other methods in fruit tree pruning. The best time for apple trees to pull branches is in July and August, when the tree is more stable and the tree forms wood faster. Generally, it is adjusted once in May and June in the spring, so it can be said that it is more appropriate to divide it twice a year.
The main time to choose is when the tree is growing fast.
The best period for apple tree branches is as follows: more than 3 years of backbone branches and perennial strong and vigorous auxiliary branches should be carried out after flowering to mid to late May (i.e., spring shoots and long periods), 1-2-year backbone branches and perennial middle branches with end fruit should be absorbed by plant roots in mid to late August, and some of them can be transported back to the roots through the phloem after being transported to the shoots. In this way, the mineral nutrients go through the process of rooting from the xylem to the aboveground phloem roots, which is called the cycle of mineral nutrients.

Branch pulling is a shaping method that artificially changes the growth angle and distribution direction of branches. Branch pulling plays a very important role in cultivating the skeleton structure of the tree, rationalizing the spatial distribution of branches, improving the light and ventilation conditions, changing the polarity of the branches, adjusting the strength of the branches, promoting or inhibiting the growth and germination of branches, and adjusting the contradiction between the growth and fruiting of fruit trees. As an important means of orchard management, branches can be pulled all year round, and autumn is the best, because autumn is the nutrient return period, timely opening angle, nutrients are easy to accumulate in the branches, so that the buds are fuller, can promote early flowering.
Compared with spring branches, strong branches will not germinate on the back. In autumn, the branches are soft and easy to pull apart.

The apple tree can start to pull branches after three months of planting, and at this time it will grow well after setting its shape.
Planting apple saplings requires efforts in soil preparation, seedling treatment, planting techniques, and post-planting maintenance. The soil should be loose and fertile acidic soil, and the apple seedlings should retain the soil mass at the roots in order to adapt to the environment. >>>More
Is there a back view in Figure 2, it is suspected that the leaf miner moth is the pest, and the others are spotted defoliation. For apple spotted defoliation, polyantibody, pentaconazole, mycloconazole, hexazototerol, daimeng, etherstrobin, ethylphosphine, fluconazole, iprodione, etc., prochlorchlortebuconazole has a good control effect on apple spotted defoliation, brown spot and anthracnose leaf blight. 400 g of prochlorchlortaconazole is recommended to be sprayed 2000 times.
Water. Sunlight. Acclimatization of the environment. and individual tree-raising behaviors.
No, if there are signs of dehydration in the scion, soak in water for 10-20 minutes.
Apple fruit drop is mainly caused by malnutrition, it is recommended to use melon and fruit Zhuang Tiling, melon and fruit Zhuang Tiling can self-regulate nutrition matching, play the role of flower preservation, fruit preservation, fruit growth, and fruit drop prevention.
