Management of sprouting and branch pulling of 1-3-year-old young apple trees in spring

How to manage the sprouting and branch pulling of 1-3-year-old young apple trees in spring? Are there any apple growers to help introduce that with the rise in prices, the economic value of apples has also increased, and many farmers have also joined the apple planting boom, so the Land planting Network has sorted out the methods of sprouting and pulling branches of young apple trees for 1-3 years in spring. the following is listed in detail for netizens' reference. The reason for sprouting young apple trees: carving buds for 1-3 years of young apple trees is an important technical measure for spring management. Correct sprouting can significantly increase the germination rate of fruit tree branches, promote the germination of stable buds and the growth of new shoots, and make young trees take shape, bear fruit early and produce early. Method 1. Carve the bud of the extended branch of the central trunk: this method mainly starts from the fourth bud under the cut mouth of the fruit tree, carving a bud every three buds, and the base 20cm does not carve the bud. Method 2. Carve buds of main branches and extended branches: carve buds of lower dorsal buds and lateral buds of annual branches to promote the formation of medium and short branches and prevent the lower part of branches from being bald. The sprouts were not engraved from the central stem 20cm and under the cut 20cm. Method 3. Carving buds of vegetative branches slowly on auxiliary branches and main branches: for annual branches more than 50m in length, except for buds within the top 20cm and 20cm from the central stem, all buds are scratched, combined with pulling branches, slow down the branch potential, promote the formation of short fruit branches and flower branches, so that young trees can bear fruit early and produce early. Method 4. Carving buds in the parts of missing branches: for the parts lacking in the main branches, auxiliary branches and branches, select short branches or leaf clusters to cut or injure the eyes from the buds, and promote new shoots to supplement the missing branches. Notes for sprouting young apple trees: sprouting for apple trees should start in late March and be completed before sprouting in early April. Those who promote long shoots should carve buds early, while those who promote short branches can carve buds late. The reason why apple trees pull branches: because drawing branches plays an important role in the shaping of young apple trees. We can change the angle and orientation of branches by pulling branches, adjust the growth potential of trees, and cultivate good tree structure, so as to achieve the cultivation purpose of early fruiting, early high yield, stable yield and high quality. The densely planted apple adopts free spindle shaping, the angle of the three main branches at the base is 70 Mel 80 degrees, which extends diagonally and evenly distributed horizontally; the auxiliary branches grow flat at an angle of 90 degrees and is inserted in the space of the two main branches; the upper main branches are inserted in the middle of the lower main branches and evenly distributed horizontally, with an angle of 80 Mel 90 degrees. Branch pulling should be carried out at the top of the new shoot to 10cm or so. The branches stretch in a straight line to prevent the branches from bending in the middle. At the same time, the strong branches of the main branches have a large angle, while the weak branches have a small angle or postpone pulling branches, and pull branches after balanced growth with other main branches in summer or autumn. When the long shoot is slowly placed on the main branch, its angle should be larger than that of the main branch, and it should grow straight or oblique, so as to ensure the balanced growth of the young tree as a whole and cultivate a good tree structure. 12 pruning methods for Apple trees fertilization and watering methods for apple trees
