Problems solved by technology

[0009] The technical problem to be solved by the present invention and the technical task proposed are for part of the broad-leaved scenic forest saplings. In the transplanting and afforestation of large seedlings, due to various reasons, the large seedlings are cultivated over a period of time, and the saplings decay prematurely, the density is too large, and the growth stagnates. In order to improve the light environment of young trees, promote the formation of new crowns, restore youthful vitality, speed up growth and improve the quality of young trees in broad-leaved landscape forests.

Embodiment 1

[0030] Cutting cultivation of 10-year-old young forest of C.camphora.

[0031] 1. Overview of saplings Camphor seedlings transplanted, 10 years old, with an area of ​​1 mu, 200 plants. The average tree height is 5 meters and the diameter at breast height is 7.5cm. The canopy density is 0.9, and the height under the branches is 3.5 meters.

[0032] 2. Cut off the trunk In the first ten days of April, when the camphor tree sprouts, cut off the upper part of the trunk and the crown, and keep the trunk height of 3 meters. The cut is sealed with plastic film.

[0033] 3. Keep the shoots in the fall of the year after the cut-off, keep 3-5 strong shoots for each cut-off tree, and cut off the excess.

[0034] 4. Fertilization: heavy fertilizer should be applied in the year of cutting, and it should be applied in 2 times; fertilization should be done once in the second year.

[0035] 5. Cultivation and management are the same as the general camphor saplings.

[0036] Present embod...

Embodiment 2

[0038] Magnolia (M.denudata) 5-year-old transplanted seedlings were truncated and cultivated.

[0039] 1. General situation Magnolia 5-year-old seedlings are transplanted, with an area of ​​1 mu and 1000 plants. The average height is 3.1 meters, the root neck is 3cm, the canopy density is 0.85, and the height under the branches is 2.1 meters.

[0040] 2. Cut off the trunk So in December, during the dormant period of the Magnolia, the upper trunk and crown were cut off, and the trunk height was kept at 1.8 meters. The cut is wrapped and sealed with plastic cloth.

[0041] 3. Keep the sprouts in June of the year after cutting off, keep 3 strong sprouts for each plant, and cut off the excess.

[0042] 4. Fertilization is the same as embodiment one.

[0043] 5. Cultivation and management are the same as ordinary magnolia young forests.

[0044] The magnolia saplings are cut dry and cultivated for two years for transplanting and afforestation. At that time, the diameter at bre...

Abstract

A trunk truncating method for culturing the young broad-leaf trees to build a scenery forest features that the crown of each young tree is truncated to retain a lower trunk with 150-300 cm in height, 3-5 branches are retained, and the pruned tree is cultured for 1-2 years.

Description

technical field [0001] The invention relates to a method for truncating and cultivating trees, in particular to a method for truncating and cultivating broad-leaved landscape saplings to improve quality and value. Background technique [0002] In the cultivation of woody plants, the method of cutting and drying is rarely used. [0003] In tree afforestation, a small number of tree species are cut and dried, such as paulownia and sassafras for afforestation, all aboveground parts can be cut off. In order to reduce the water evaporation of seedlings and improve the survival rate of planting. [0004] The mowing of the tea tree platform also cuts off the aboveground part in order to rejuvenate the old tree and form new plants. Its object is old tea tree. [0005] My invention patent application number 2004100182699 "a kind of method for cultivating Kudingcha seedlings" has the content of cutting and drying. This patent refers to that 1 / 3 tip of nurse...
