Shaping and winter pruning of persimmon trees

First, shaping: Persimmon trees meet the needs of dwarfing and dense planting cultivation, mainly using natural happy shape, changing trunk shape and trunk sparse layer shape and so on. The characteristics of the sparse layer shape of the trunk: there are obvious central leading trunk, and the main branches are distributed in layers, including 3 main branches in the first layer, 2 main branches in the second layer, 1 main branch in the third layer, staggered between the upper and lower layers, and the distance between layers is 60-70 cm. Each main branch bears 2-3 lateral branches, the distance between the two branches is about 60 cm, and the bearing branches are on the lateral branches. The height of the trunk is about 1 meter. The trunk sparse layer shape is suitable for orchards with poor site conditions, and the natural happy tree shape can be used in orchards with better site conditions. After entering the full fruit period, in order to make the operation more convenient, the trunk sparse layer and retain the first layer of main branches can be improved to happy tree shape without affecting the yield. Second, winter pruning 1. Pruning of fruiting mother branches: a sufficient number of fruiting mother branches must be retained in winter pruning, and the fruiting branches of the previous year are less, which can be reserved as this year's fruiting mother branches. When the fruiting mother branch is too dense, it remains strong and weak, and staggers from left to right. two。 Pruning of developmental branches: thinning the weak branches in the lower part of the inner chamber or large branches. The moderately developed branches of 25-45 cm are easy to form flowers and form fruiting mother branches, which can be cut off by 1 stroke 3, and the short ones are not short. The development branches that are too dense can be removed by "staying and pouting" to promote the formation of the golden mean twigs in the second year. When cutting the developing branches at the young stage, attention should be paid to the outward direction of the first bud under the cutting mouth.
