Embodiment 1

[0021] Plastic and pruning of newly planted pepper saplings: two cultivation modes of densely planted pepper garden and single-row planting in terraced fields are adopted. The 2-year-old Dahongpao pepper seedlings with a height of 1.2m and a thickness of 0.75cm were selected for planting on April 5. The tree hole was 60cm square, the row spacing of pepper densely planted was 3m×4m, and the row spacing of single row planting in terraced fields was 3m. After planting, keep 40-60cm to dry. In mid-June, fix the side branches that sprouted on the main trunk, and keep 2-4 side branches at an interval of 10 cm from the top of the seedling trunk, and make the side branches evenly distributed in space. In the spring of the second year, pull the side branches at an angle of 60-70 degrees. After the third year, before germination every spring, the strong buds of the pumped branches should be cut short to keep the length of 40-60cm, and the fruiting branches and weak branches should be c...

Embodiment 2

[0025] Results Pruning of large trees: The test subjects were two cultivation models of dense planting garden of Dahongpao Zanthoxylum bungeanum and terraced fields with single-row planting of Zanthoxylum bungeanum. The row spacing of densely planted Zanthoxylum bungeanum is 4m × 5m, the average crown width is 3.5m × 8.8m, and the canopy has been closed. During the dormant period in winter, remove the redundant large and thin branches on the trunk and main branches, and cut back the peripheral 3-5-year-old extended branches on the remaining large branches, and keep the length of 40-60cm. Afterwards, every winter or spring, before germination, the one-year-extended branches will be cut short, and the length will be kept at 40-50cm. Combined with pepper pruning, the thin and weak branches will be harvested. The control is the same site conditions and the same age Zanthoxylum bungeanum of the same variety, extensively cultivated according to the traditional method without pruning...

Abstract

The invention discloses a Chinese prickly ash tree trimming method, and relates to the field of trimming of economic forests. The method mainly adopts two trimming means of heavy short section promoting producing and vigorous shoot growing and pruning harvest, shaping and trimming are described for newly-planted young trees and fruited big trees respectively, producing and vigorous shoot growing are achieved after heavy short section, by means of slow release and branch pulling, a large number of flower buds can be formed through differentiation, inflorescence is big and the fruit setting rate is high; by adopting the pruning harvest method, fruit branches and moribund branches are cut out, the illumination condition can be effectively improved, moisture and nutrient consumption is reduced, the capacities of vigorous branch producing and flowering and fruiting in the next year are improved, and the tree vigor and the quantity of fruiting of a Chinese prickly ash tree are greatly improved.

Description

technical field [0001] The invention relates to the field of pruning of economic forests, in particular to a method for pruning prickly ash trees. Background technique [0002] Zanthoxylum bungeanum is a famous spice, seasoning, and oil tree species unique to my country. Zanthoxylum bungeanum is resistant to drought and barrenness, and vigorously developing Zanthoxylum bungeanum is of great significance to improving the ecological environment in mountainous areas, increasing the income of the masses, and meeting the needs of the people's lives. my country's Zanthoxylum bungeanum has been extensively cultivated for a long time without paying attention to pruning, resulting in late fruiting, weak tree vigor, premature tree aging, low yield and poor quality. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a pruning method of Zanthoxylum bungeanum, according to the growth and fruiting characteristics ...
