The processing of apple branches in the year is the most important and most commonly encountered problem in pruning. Must be taken seriously and correctly, specifically summarized in six points:
The strong are sparse. Thick branches with strong axis and 50 cm growth should be dredged to avoid affecting the structure. For example, competitive branches, large branches sprouting on the back, peripheral trigeminal and bifurcated branches should be dredged. Extremely heavy and short, spurring twigs, taking up space.
Golden dump. The modest branch with space is generally thrown away. Do not throw the middle branch (usually below 50 cm) on the trunk, but also pull it horizontally; leave one middle branch on the main branch every 20 cm or so to dump the middle branch on the back. Branches can be taken in the growing season or left with a twisted tip of about 30 cm, or germinated after sprouting; for the moderate branches on the fruiting branch group, if there is space without crossing the gate, you should throw them out; on the back there are moderate branches If you do n’t have a branch on your back, you can pull the middle branch on your back to your back.
Secret person. For over-dense branches, it is generally considered that there are more than two branches in the same direction within 20 cm, and thinning can be carried out. The remaining branches can take up 20 cm of space after sprouting.
The injured are injured. For branches that have room to grow and are relatively large and large, you can take the branches in the growing season and perform basic wounding during winter shearing. Use a hand saw to cut 1/4 to 1/3 at the base of the branches and grow in the second year. Depending on the season, if the branches are still strong, you can take branches and ring strips again to promote weakening, form flower buds, and press the fruit to shoot.
The weak go. Weak branches refer to thin branches, which are generally thinned, especially those branches that have no fruiting lining, undersides, and lower skirts that are not continuously flowering. They can be removed from the base to avoid consuming tree nutrients. ".
Fork shrinks. The cross-chain gate branches should be retracted to a place where there is space, and the space occupied by the original branch group should be maintained without interference. Each of them should perform its duties, and the overlapping branches should be retracted or changed direction or sparse, improve the structure, and increase the light.
The amount of branches after pruning in winter, the result is about 100,000 square meters of large trees is appropriate, the young tree without affecting the structure of the tree, the more branches the better.
