2. Prune branches: Prune cherries once after they bear fruit. At this time, the main pruning is dry branches and branches infected with pests and diseases. Because plants consume more nutrients at the fruiting stage, they will lack nutrients at this time. Such branches will waste nutrients and must be pruned in time.
3. Sparse pruning: Prune once in late autumn. At this time, it is mainly to cut off the messy branches, too dense branches and too long branches on the cherry tree, which can reduce a lot of nutrient consumption, promote better light transmission inside, and be conducive to overwintering and later growth and germination. When trimming, you must choose a sharp knife to ensure that the trimming incision is flat, so that you can recover faster.
4. Maintenance after pruning: No matter at which stage the cherry tree is pruned, the wound after pruning should not be wetted with water to avoid the wound rotting. After pruning, strengthen ventilation and get more sunshine, the wound will heal faster and recover faster.
Management skills of cherry saplings;
1, flower and fruit management: spray Qiangguodiling once before flowering, fruiting and maturity of cherry trees to ensure smooth flowering and fruiting of cherries. In winter, drooping branches, twigs and branches that bear fruit many times should be cut off. In bud stage, stunted flowers and deformed flowers should be cut off. There are about two flowers on each inflorescence.
2. Shaping and pruning: cut the branches into hearts, with the trunk controlled at about 50 cm, without a central trunk, with about 3 main branches and an angle of 40 degrees. Leave 3 lateral branches on each main branch, with an interval of 25cm. You can also choose the central trunk, and the number of main branches on the trunk should be controlled at 8~9, and the height of the tree should be controlled during pruning to keep the stem fixed.
3. Harvest management: Because cherry trees are fruits with continuous fruits, they should be harvested in batches. The time depends on the maturity of the fruit on each tree and the market demand. Immature after harvest needs low temperature preservation to achieve high yield. Different cherry varieties have different harvesting time. For example, soft meat varieties will be harvested earlier because of their fast maturity, while hard meat will be harvested later.
4. Post-harvest management: After all the cherries are harvested in that year, base fertilizer can be applied as soon as possible. This can also play the role of fertilizer as soon as possible and increase the nutrients needed by cherry trees in winter. Moreover, September is the peak of cherry root growth and development, which is beneficial to root absorption of nutrients, and can also restore root damage and produce more new roots.
