Embodiment Construction

[0016] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0017] Embodiments of the invention include:

[0018] (1), specific examples of implementation:

[0019] The experiment was carried out in the Huayang Garden of Zhenjiang Institute of Agricultural Sciences in the hilly area of ​​Jiangsu. The tested varieties were 4-year-old 'Hongdeng' and 'Meizao' large cherry trees. In the north-south direction, the row spacing of "two branches and one heart" and free spindle-shaped trees is 3m×4m, and the row spacing of evacuated layered trees is 4m×4m.

[0020] (2) Implementation of processing:

[0021] Choose 8 plants for each tree shape, and a single plant is 1 plot. Investigate the tree height, crown diameter, number of fruits, length and thickness of ...

Abstract

The invention discloses a method for pruning a densely-planted large cherry tree to form a high photosynthetic efficiency tree form. The tree form has the characteristics of two branches and one heart shape, namely two boughs and a central trunk of a tree body. The tree is about 2.5-3m high, the trunk is 0.4-0.5m high, only the two boughs on the first layer are retained, the two boughs grow opposite to each other basically, the included angle is commonly between 80 degrees and 90 degrees, no lateral branches need to be retained, and bearing branches directly grow on the boughs. All kinds of branch groups are evenly retained on the portion, above the boughs on the first layer, of the central trunk, and the branch groups are mainly medium and small branch groups. The high photosynthetic efficiency tree form of the densely-planted cherry tree can be formed fast, illumination is good, and the densely-planted large cherry tree is early in blooming and fruit bearing, high in output, good in quality and convenient to manage manually or through mechanical operation.

Description

technical field [0001] The invention relates to a method for shaping and pruning fruit trees, in particular to a method for shaping and pruning densely planted large cherry trees with high light-efficiency tree shape. Background technique [0002] Big cherry is the abbreviation of European sweet cherry, which belongs to the deciduous tree fruit tree of Rosaceae. The young big cherry tree grows vigorously, with obvious top dominance, late fruiting, long production period and slow effect. At present, the most widely used tree shapes of large cherry trees in my country mainly include free spindle shape, layered shape, and cluster shape. Especially varieties such as Red Lantern, Italian Zaohong, Meizao, and Labins adopt the traditional free-spindle shape, often because of their strong dryness, the main branches (large-scale fruiting branch groups) are empty, and the tree shape is tall so that they can be picked. It is inconvenient; if the traditional trunk layered shape and clu...
