Example Embodiment

[0015] Example 1:

[0016] A method for topping and pruning the crown of plum trees includes topping and pruning the grafted plum saplings of the year before they are planted.

[0017] (1) Prepare 1 ordinary branch shears for cutting off the top buds of plum trees in summer and prune the long branches of plum trees in winter.

[0018] (2) The height of the grafted plum tree seedlings of the year before planting is generally more than 1m. The interface of the seedlings grafted by the cutting method is generally 10cm from the ground, that is, the rootstock length of the seedlings is 10cm, and the new shoots grow after grafting. Topping at 20-30cm, stimulating 3-5 new shoots. That is, the standard height of the trunk of the plum tree is 30-40cm, leaving 2-4 branches, and the branch length is 30-50cm for planting.

[0019] (3) Summer topping:

[0020] ①In the first ten days of May, perform the first topping of the elongated branches (vertical growth of the main branch, horizontal or obliq...

Example Embodiment

[0025] Example 2:

[0026] A method for topping and pruning the crown of plum trees includes topping and pruning the plum trees that enter the high-yield period from the 5th to the 6th year after planting.

[0027] (1) Prepare 1 branch pruner for cutting off the top buds of plum trees in summer and pruning the long branches of plum trees in winter.

[0028] (2) The plum garden managed by the technology of the present invention has entered a high-yield period from the fourth to the fifth 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 single plum tree crown control in orchards.

[0029] (3) Summer topping:

[0030] ①In the first ten days of May, perform the first topping of the elongated branches (main branches that grow vertically, and lateral branches that grow horizontally or obliquely) in the first round of the plum tree that year. When the elongated branches reach 30-40c...

Abstract

The invention discloses a topping and pruning method for a plum tree crown. The method includes the steps of topping in summer and pruning in winter, the step of topping in summer includes three times of topping, the topping for the first time is at the first ten-day period of May, the topping for the second time is from the last ten-day period of June to the first ten-day period of July, and the topping for the third time is at the first-ten-day period of August. The pruning time in winter is from the middle ten-day period of November to the middle ten-day period of January in the next year. The topping and pruning method can promote dwarfing of a plum tree, the plume tree crown can be formed and is sturdy in main and lateral branch, reasonable or ideal in number and distribution or structure and high in yield, the situations that redundant branches consume nutrient and cause crown closure are reduced, dwarfing, ventilation and light transmission of tree bodies and cultivation management of a plume tree garden are facilitated, reproduction growth is promoted through dwarfing, close planting, centralized nutrient supplying and photosynthesis enhancement, differentiation forming of bearing branches and flower bud differentiation can be accelerated, and the plum tree can be promoted to bear fruits in advance and promote the high yield of the plum tree garden.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for topping and pruning plum tree crowns. Background technique [0002] Prunus is resistant to barrenness and drought, and is especially suitable for the special environment of rocky desertification mountainous areas with high rock exposure rate, fragile ecology, serious soil erosion, thin soil layer, and prone to drought and flooding. It is an important fruit tree in limestone mountainous areas of our country. The elongated branches of plum trees do not bear fruit, because they mainly carry out vegetative growth and do not differentiate flower buds, but they can be cultivated and extended branches through topping and pruning, which become the basic skeleton of the high-yield crown of plum trees; ) in the middle and lower part of the axillary buds, when the conditions are suitable, a small number of axillary buds can produce short fruiting branches and we...
