Shed erecting-free scaffold self-shaping technology for pears

Abstract

The invention relates to a shed erecting-free scaffold self-shaping technology for pears, which is designed for overcoming the defects of a Japanese horizontal scaffold cultivating technology for the pears. Due to the adoption of the technology of utilizing an integral corrugated structure of a pear garden formed by main branches of the pears, the capacity of resisting the wind damage of tree bodies is improved; the light interception area is increased and the output is improved; a great quantity of wood is saved; and the shed erecting-free scaffold self-shaping technology for the pears is convenient to manage. The main branches are bent in an arc shape and have mild growth vigour. Lower branch groups are easy to cultivate. The main branches are strong and have long service life.

Description

technical field [0001] The invention relates to a pear tree shaping technology, in particular, it uses the branches of the pear tree itself to complete the shaping of the scaffolding under the condition of no scaffolding. technical background [0002] Due to the physiological characteristics of the pear tree, it is easy to fall off when encountering wind. Trellis cultivation originated in Japan with many typhoons. In 1782, there was a record of the cultivation of pear tree trellises in the "Secret Book of Pear Fruit Breeding" written by Taifu Ayuan. The original purpose of trellis cultivation was to resist the fruit drop caused by typhoons. During the cultivation process, it was found that the tree body of trellise cultivation was low and easy to manage. It was widely promoted in Japan in the middle of the last century, and in the mid-1990s in coastal areas of my country such as Jiangsu and other places. promote. [0003] At present, the Japanese pear tree horizontal scaff...

AI Technical Summary

Problems solved by technology

[0003] At present, the Japanese pear tree horizontal scaffolding cultivation mode promoted in China has the following defects: ① The cost of building the scaffolding is high. In 2002, every 667m 2 Need to invest 4750 yuan

② Difficult to cultivate tree shape, and labor-intensive pruning

④The dense metal grid makes it inconvenient to bind and fix branches, thin flowers and fruits, etc.

⑤ The branches and leaves are distributed horizontally along the scaffold surface, the leaves are crowded, the space utilization rate is low, the light energy interception rate is low, and the yield level is low

⑥ In addition to the southeast coastal areas in my country, other areas are rarely affected by typhoons, and Japanese trellis cultivation is not suitable for the natural climate characteristics of most areas in mainland China
