1, Time: Transplanting mature fruit trees in spring is slow, and keeping a certain crown will delay the prosperity of the next year. In winter, the leaves of transplanted trees have fallen off, which is beneficial to the healing of broken roots and can grow new roots under suitable conditions, which can lay a good foundation for the prosperity of trees in the coming year.

2. Digging: Draw a circle with a radius of 1m around the trunk and dig the big tree from outside the circle. Dig to a depth of 60 cm, and dig obliquely inward to make a mud ball. Expand the base of the branches of the tree with a crane cover, so that the earth ball can be hung to tie the straw rope. Enclose the topsoil, then wrap it in straw, then hang it and put it on the truck. Walk slowly on the road to prevent the branches, leaves and epidermis of trees from being crushed during transportation. At the same time, do a good job of digging holes. The plant spacing is 6 meters, the pit depth is 80 cm, 1 m square, and the topsoil and raw soil are planted separately.

3. Plastic pruning: For the transplanted mature trees, plastic pruning is heavier, but not all of them are heavy, only partial. Generally, 5 ~ 6 large branches are reserved in the whole tree, and the remaining large branches and overlapping branches are properly thinned out, and all cross branches and diseased dead branches are thinned out. When the space is large, the middle of the extended branches (main branches) of the large and middle branches can be cut off, and the flower amount of the main branch can be cut off by 2/3, and the flower amount of the auxiliary branch can be cut off by 1/3, and the combination of long, medium and short pruning can be adopted. For newly planted trees, we must first ensure survival, and then consider the amount of flowers left and the results. The remaining flowers should be reduced as much as possible. If the annual fruit yield of the original tree is more than 200 kg, the post-planting yield should be controlled within 50 ~ 100kg. When pruning, take back the temporary auxiliary branches of large, medium and small branches, and leave less flowers and fruits for the big branches.

4. Planting: While doing the above work well, spray compound carbendazim liquid medicine on the dug tree holes. First, backfill the hole with 20 cm of endogenous soil, and then spray the potion again. If possible, apply1~ 2kg of phosphorus and potassium fertilizer to each hole and mix the soil evenly. Lift the treated tree and put it in the center of the hole, backfill the topsoil by 20 cm, and shake it a few times before it is slightly practical. Then backfill 20 cm of soil and shake the tree a few times to make the root system of the fruit tree solid in the soil. Finally, backfill 20 cm for compaction, and be careful not to hurt the root bark.
