Embodiment 1
[0016] A topping and pruning method for the crown of a plum tree comprises the topping and pruning of the year when the grafted plum saplings are planted.
[0017] (1) Prepare a pair of ordinary branch shears, which are used to cut off the top buds of plum trees in summer and to trim the elongated branches of plum trees in winter.
[0018] (2) The grafted seedlings of that year’s plum tree can reach a height of more than 1m before planting. The interface of the seedlings grafted by cutting grafting is generally 10cm above the ground, that is, the rootstock length of the seedlings is 10cm, and the new shoots grown after grafting are as long as 10cm. When the top reaches 20-30cm, 3-5 new shoots are triggered. That is, the standard height of the main trunk of the plum tree is 30-40cm, and 2-4 branches are left, and the branch length is kept at 30-50cm for planting.
[0019] (3) Summer topping:
[0020] ① In the first ten days of May, the first topping was carried out on the elo...
Embodiment 2
[0026] The invention relates to a topping and pruning method for the crown of a plum tree, which comprises topping and pruning for a plum tree that enters a high-yield period in the 5th to 6th year after planting.
[0027] (1) Prepare a pair of branch shears, which are used to cut off the top buds of plum trees in summer and to trim the elongated branches of plum trees in winter.
[0028] (2) The plum orchard managed by the technology of the present invention has entered the high-yield period from the 4th to the 5th year after planting. At this time, the height of a single plum tree is nearly 2m, and the width of the tree is nearly 2.5-3m, which has reached the standard for crown control of a single plum tree in orchards.
[0029] (3) Summer topping:
[0030] ① In the first ten days of May, the first round of long branches of the plum tree that grows in the first round (the main branch that grows vertically, and the side branch that grows horizontally or obliquely) is topped ...
