Method for grafting chestnut tree

Abstract

The invention relates to a method for grafting chestnut trees, and belongs to the technical field of forest fruit tree grafting. The method for grafting Chinese chestnut trees uses a single bud green wood of Chinese chestnut as a scion, the scion and a stock are in side grafting. The shape of a side grafting notch on the stock is an inverted triangle, and the peak of the inverted triangle is provided with a lengthwise cutting extending downward. The single bud green wood with a xylem is used as the scion. In a grafting process, just a forming layer on a section is exposed in air, so brown stain area is greatly reduced, and survival rate after grafting is improved. The single bud green wood is easier to insert into the side grafting notch, so as to improved operation speed, shorten contact time of the forming layer and air, reduce brown stain degree, and improve survival rate. In addition, the cortex of the inverted triangle part of the notch is stripped, so that the cortex on two sides of the lengthwise cutting is easy to pick open, pick-open degree is large, and the scion is easier to insert, so as to improve inserting speed, shorten contact time of the forming layer and air, and improve survival rate.

Description

technical field [0001] The invention relates to a method for grafting chestnut trees, which belongs to the technical field of grafting forest and fruit trees. Background technique [0002] Most of the high-grafted chestnut trees are grafted in spring. Although the grafting survival rate is high during this period, due to various reasons such as improper operation and wind breakage, some scions still fail to survive. If the unsurviving large branches are reconnected in the coming year, the 1-year growth cycle will be wasted, and the forest will be disordered. Most of the current-year branches used as chestnut scions are 5-sided, rich in tannins and prone to browning. In addition, the cortex of large tree rootstocks is usually thick, so the traditional T-shaped budding is not only inconvenient to operate, but also has a low survival rate. Contents of the invention [0003] The object of the invention is to provide a chestnut tree grafting method with high survival rate and ...

Problems solved by technology

If the unsurviving large branches are replanted in the next year, the growth cycle of one year will be wasted, and the forest will be disordered.

Most of the current-year branches used as chestnut scions are 5-sided, rich in tannins and prone to browning. In addition, the cortex of large tree rootstocks is usually thick, so the traditional T-shaped budding is not only inconvenient to operate, but also has a low survival rate.
