Problems solved by technology

[0002] At present, the main tree shapes used in the cultivation of sweet cherries are spindle-shaped, arbuscular, and small-crown sparse-layered. The branches are flattened in winter, and the short fruiting branches in the form of bouquets are used to bear fruit. The technical essentials are simple, but the tree is vigorous, the annual growth of side branches is large, it is easy to take back branches, and the fruiting branch groups are not easy to renew. However, the existing shaping methods are in the During the production process, it is prone to a series of problems such as tree canopy avoidance, poor ventilation and light transmission, inconvenient mechanical operation, large amount of labor such as picking and pruning

Embodiment 1

[0030] The experimental garden is located in Yinjiazhuang Village, Xiazhang Town, Daiyue District, Tai'an City, Shandong Province. The sweet cherry varieties are "Brooks", "Meizao" and "Sumit", and the rootstock is Gisela No. 6. The 3-year-old seedlings with branches were planted in 2015, with a row spacing of 1 meter x 3 meters and an area of ​​2 mu.

[0031] Erection of support: The support is composed of 4 steel wires with fixed heights of 1.5 meters, 2.2 meters, 3 meters and 3.5 meters respectively, and the central stem is bound to the steel wires; the distance between plants and rows is 0.8-1.0m×2-3 m, 667m 2 Plant 220-420 plants, and the specific planting density should be appropriately adjusted according to the growth potential of the variety and rootstock combination, soil fertility conditions and planting mechanization degree; Upright and strong, the trunk height is about 50-60cm, and 30-50 fruiting branch groups grow evenly on it, with a length of 5-50cm; the first...

Embodiment 2

[0048] The experimental garden is located in Yinjiazhuang Village, Xiazhang Town, Daiyue District, Tai'an City, Shandong Province. The sweet cherry varieties are "Hongmi", "Brookes", "Sumit" and "Meizao", and the rootstock is Gisela 6. The 2-year-old seedlings were planted in the spring of 2017, with a row spacing of 0.7 m x 2 m and an area of ​​2 mu.

[0049] When planting, the tree is bound to the steel wire of the support, and the stem is not fixed. From a height of 50cm above the ground, every 10-15cm, select high-quality buds in different directions, and engrave the buds at 0.5cm above the buds to promote directional branching. Make the small fruiting branches distributed in a spiral shape ( Image 6 ). Maintain the advantage of the central trunk extending the shoot, cultivate the branches that germinate on the main trunk as the fruiting branch group, and pick the new shoots continuously; in winter, the branches that germinate on the central trunk are cut short, and the...

Abstract

The invention belongs to the technical field of agriculture, and in particular relates to a method for shaping and pruning sweet cherry columns suitable for labor-saving operations. The pruning method is as follows: (1) Erection of supports; (2) If the 2-year-old seedlings are used for colonization, the buds are carved to promote the directional branching, so that the small fruiting branches are distributed in a spiral shape; the new shoots are continuously topped; heavy pruning in winter (3) pruning of trees in the 2nd-3rd year of planting and full fruit stage (5) supporting technical measures; the present invention provides a sweet cherry cylindrical shaping and pruning technology for labor-saving operation according to the characteristics of gisela dwarfing rootstocks The pruned sweet cherry cylindrical shape of the present invention has a stable tree body skeleton and strong light transmission, which can make the branches see the light without excessive nutrient consumption; fast forming, early high yield, high-quality fruit rate; simple pruning method It is easy to walk, easy to pick, labor-saving; wide between rows for mechanized operation and high-density cultivation of facilities and other advantages.
