Dormancy pruning is winter pruning, from normal defoliation in autumn to germination in the next year. At this time, the storage nutrients of fruit trees have been transferred from branches to branches and roots and stored. At this time, less nutrients are lost by pruning, and because there are no leaves, it is easy to analyze the structure and pruning reaction of the tree. Therefore, winter pruning is the main pruning period of most fruit trees; However, there are exceptions. For example, pruning of walnut trees during dormancy will cause bleeding, and it must be pruned before falling leaves in autumn or after germination in spring and before flowering. Grapes also have bleeding period before germination, so pruning should avoid this period.
When fruit trees grow seedlings in early stage, most of them will be carried out in cultivation cups, which is beneficial to early growth and convenient for temperature regulation. When they are long enough to be transplanted, how long will it take to dry and prune them after they are set? Let me tell you something:
How long can the fruit trees be pruned after transplanting? If the saplings are planted in the soil, most fruit trees can do it. When they grow above 100 cm, they can be trimmed. The height of the trunk has a great influence on the whole tree and its later structure. If it is set too high, the crown will form later. If the trunk is short, the distance between the root system and the crown is short, and the crown is easier to form, which is also convenient for later management.
After the stem is fixed, pay attention to leaving buds and branches according to the parts of the tree to be used in the future. In order to protect the cut wound, it can be wrapped and sealed with plastic sheets to prevent the wound from losing water or bacterial infection from affecting the growth of fruit trees. As for early pruning, the lower branches and buds can be cut off after transplantation. After the trunk is fixed, the central branch, main branch and fruiting branch of the fruit tree are selected according to the tree shape for different fruit trees to cultivate.
Do some management according to the needs after drying, such as watering in time in case of high temperature and drought, and pay attention to wind protection. Straw can be used to cover the soil in the vertical projection part of the tree crown to avoid water evaporation and keep warm and cold.
To sum up, when transplanting fruit seedlings, they can be dried when the height reaches 1 m or more. Fixed drying time should not be fixed, and should be treated differently according to the characteristics of different fruit trees. After planting, in order to improve the survival rate of other plots, post-planting management should be strengthened, and light cutting should be the main method in the early stage.
