Problems solved by technology

[0003] At present, the pruning of the main trunk of the plant is mostly aimed at the street trees, so that it does not hinder the passage of people and vehicles, but this kind of pruning is often not beautiful enough, and there is no special pruning technology used so far to make the main trunk show bamboo-like branch marks.

Embodiment 1

[0023] The embodiment of the present invention discloses a method for shaping and pruning the trunk of Ulmus elmanus, comprising the following steps:

[0024] 1) select seedlings; select the seedlings grafted at the beginning of April in spring, plant height 1.8m, ground diameter 2cm;

[0025] 2) Select the branches that form the bamboo-shaped trunk: during the dormant period, along the trunk, from bottom to top, every 10cm, select two side branches on the left and right symmetrical positions on the trunk, so that the side branches and the trunk form an inverted "one" font;

[0026] 3) Pruning of unselected branches: carry out conventional pruning on the remaining side branches: close to the trunk of the elm, and cut off the unselected branches from the base

[0027] 4) Bamboo-shaped trunk pruning: the branches selected in the step 2) are trimmed, and the pile head of 0.5cm is reserved to form a bamboo-shaped trunk;

[0028] 5) Growth period management: 1) When the thickness...

Embodiment 2

[0030] 1) select seedlings; select cutting seedlings at the beginning of June in summer, plant height 2.5m, ground diameter 3cm;

[0031] 2) Select the branches that form the bamboo-shaped trunk: During the dormant period, along the trunk, from bottom to top, every 12cm, select two side branches on the left and right symmetrical positions on the trunk, so that the side branches and the trunk form an inverted "one" font;

[0032] 3) Pruning of unselected branches: carry out conventional pruning on the remaining side branches: close to the trunk of the elm, and cut off the unselected branches from the base

[0033] 4) Bamboo-shaped trunk pruning: the branches selected in the step 2) are trimmed, and the pile heads of 0.75cm are reserved to form a bamboo-shaped trunk;

[0034] 5) Growth period management: 1) When the thickness of side branches left in step 2) exceeds 0.8cm, cut them off in time against the main trunk. .

Embodiment 3

[0036] 1) select seedlings; select the seedlings grafted at the beginning of April in spring, plant height 2.2m, ground diameter 2.5cm.

[0037] 2) Select the branches that form the bamboo-shaped trunk: during the dormant period, along the trunk, from bottom to top, every 15cm, select two side branches on the left and right symmetrical positions on the trunk, so that the side branches and the trunk form an inverted "one" font;

[0038] 3) Pruning of unselected branches: carry out conventional pruning on the remaining side branches: close to the trunk of the elm, and cut off the unselected branches from the base

[0039] 4) Bamboo-shaped trunk pruning: the branches selected in the step 2) are trimmed, and the pile head of 1cm is reserved to form a bamboo-shaped trunk;

[0040] 5) Growth period management: 1) When the thickness of side branches left in step 2) exceeds 0.8cm, cut them off in time against the main trunk. .

[0041] The inventor has verified three kinds of embod...

Abstract

The invention discloses a method for reshaping and pruning the trunk of ulmus pumila. The method for reshaping and pruning the trunk of the ulmus pumila comprises the processes of seedling selecting,pruning time determining, pruning, growth period management and the like. According to the method for reshaping and pruning the trunk of the ulmus pumila, bamboo-shaped branch marks are left on pruning parts, so that the ornamental value of the ulmus pumila is improved, and the transportation of nutrient substances is not hindered.

Description

technical field [0001] The invention relates to the technical field of nursery stock growth management, and more specifically relates to a method for shaping and pruning the trunk of elm elm. Background technique [0002] The plastic pruning of traditional ornamental plants is to carry out certain pruning on the crown and branches of the plants, so that the layout of the branches is reasonable, and a certain tree structure is achieved for viewing, and it can adjust the transportation of nutrients and water, balance the tree vigor, Change the relationship between vegetative growth and reproductive growth, promote flowering and fruiting, and improve the ventilation and light transmission conditions of the canopy by removing dead branches, diseased and insect branches, and dense branches, so that the plants grow robustly and reduce the occurrence of diseases and insect pests. [0003] At present, the pruning of the main trunk of the plant is mostly aimed at the street trees, so...
