Free-spindle-shaped tree form of Cangxi snow pears and shaping method of tree form

Abstract

The invention relates to a free-spindle-shaped tree form of Cangxi snow pears and a shaping method of the tree form. The tree form like the shape of cedar, the total height of the tree is 300-350 cm, the height of a trunk is 40-60 cm, a central trunk is provided with 15-20 main branches, attachment sites of the main branches are distributed in a spiral mode, the adjacent attachment sites of the main branches are arranged according to the vertical distance of 10-15 cm, the staggered angle of the adjacent main branches is 90-180 degrees, the length of the main branch on the lowest layer is 200 cm, the length of the main branches is sequentially decreased from bottom to top, and the main branches are provided with fruiting mother branches. The shaping method of the tree form comprises the steps of field planting, main branch cultivation, fruiting mother branch cultivation and the like. Compared with conventional thinning layering, the method has the advantages that the branch number of branches is small, effective leaf curtain layers are thick, photosynthesis efficiency is high, pest and disease damage is small, high yield and high quality are facilitated, the yield can be increased by about 20%, the shaping method is simple, and labor can be saved by about 50%.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and relates to a tree structure of Cangxi pear and a shaping method thereof. Background technique [0002] Cangxi Sydney is a specialty product of Cangxi County, Sichuan Province, and a Chinese geographical indication product. Cangxi Sydney, also known as Shijia pear, is a unique variety found in the sand pear community in Cangxi County, with a cultivation history of more than 1,200 years. Its appearance is beautiful, its flesh is white, its taste is as sweet as honey, its fragrance is free of slag, and it melts in the mouth. The average single fruit weighs 500-700g, and the large one can reach 2300g. It is known as the "King of Sand Pears". At present, Cangxi County has a planting area of ​​165,000 mu, with an annual output of 100,000 tons, covering 31 towns, 236 villages, and 85,000 households. As one of the 10 counties in the sand pear region (five provinces and cities) in the...

Problems solved by technology

This tree shape is usually tall, which is not conducive to field management. The subordinate relationship of branches is easy to be confused, and the adjustment of strong tree vigor is not effective. , in the full fruit stage, the crown is easy to close, and the fruit part is easy to move outward, resulting in gradual disorder of the tree shape, low photosynthetic utilization rate, serious disease and insect pests that are difficult to control, seriously affecting fruit yield and quality, and difficult agricultural operations and pruning techniques. Disadvantages of difficulty, labor intensive and high production cost
