Bending method for forming narrow crown tree forms of sweet cherry trees

A sweet cherry, narrow crown technology, applied in the agricultural field, can solve the problems of wasting the amount of branches and leaves of young plants, weakening the overall tree vigor, difficult to form flowers, etc., and achieve the effects of avoiding splitting of branches, low branch density and large branch angle.

Problems solved by technology

[0004] Sweet cherry saplings grow vigorously, with a large growth volume, strong apex and apex dominance, and because of the same season of rain and heat in most parts of our country, the humidity and heat index is high, which exacerbates the vigorous growth of the tree and is not easy to flower. Therefore, sweet cherry plastic surgery in my country Pruning is difficult to simply copy foreign methods
The traditional method of pulling branches of sweet cherry in my country is no longer suitable for the cultivation of modern narrow-crown trees. Without the effect of easing the branch potential, the thickness ratio between the central trunk and the small main branches cannot be opened, resulting in the phenomenon of "neck pinch

Embodiment Construction

[0028] A kind of sweet cherry narrow-crown tree shape construction pulls the method, comprises the following steps:

[0029] The first step is to determine the branching time:

[0030] The new shoots of the current year and the 1-2-year-old branches can be pulled during the growth period of the new shoots in the growth season or the slow period, or after germination in spring to before the leaves are displayed.

[0031] The second step, base twisted branch injury:

[0032] First, make the base of the branch to be pulled close to the central trunk; pinch and pull down the branch from a position 1 cm above the base of the branch, until the angle between the branch and the central trunk is 90°-110°, stop pulling down, and then clockwise Twist the branch in the direction until the branch is twisted and does not break, and press down on the branch to keep it drooping.

[0033] Do as follows:

[0034] The thumb of the left hand cooperates with the index finger and middle finger t...

Abstract

The invention provides a bending method for forming narrow crown tree forms of sweet cherry trees. The method includes the following steps that firstly, bending time is determined; secondly, the base of a branch is twisted to be damaged; thirdly, bending is carried out. The method is suitable for forming the narrow crown tree forms like a high spindle form in the 'wide line and dense plant' planting pattern of the sweet cherry trees under the weather conditions of China; the method has a good bending effect, a basal angle is formed through bending, a tip rake angle is not easily formed, and branch vigor cultivation, flower formation and fruit bearing are facilitated; meanwhile, in the tree body forming process, the growth angle of an extension head competitive branch of a center trunk can be adjusted at any time so as to keep the growth vigor of the center trunk, no branch will be missed when young trees without fruit are shaped, adverse effects on the growth of tree bodies are avoided, the growth and shaping of the tree bodies are facilitated, and the sweet cherry trees can bear ahead of time and have a high yield.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for constructing and pulling branches in the shape of a sweet cherry narrow-crown tree. Background technique [0002] At present, the labor-saving and mechanized cultivation of fruit trees in my country is the general trend. The planting method of "wide rows and dense plants" is adopted, that is, the distance between plants is about 1m, and the distance between rows is about 4m, which can effectively facilitate the mechanized operation of orchards. The tree shape adopted in the planting method of "wide rows and dense plants" needs to be changed from the original large crown shape to narrow crown tree shapes such as high spinneret shape, trunk shape, and ultra-slender spinneret shape. [0003] Narrow-crown trees focus on cultivating a strong, upright central leader to reach the intended height of the tree. The central leading trunk is the only permanent branch of t...
