A kind of grafting method of chestnut tree leaving groove

Abstract

The invention provides a chestnut tree grafting method, which relates to the technical field of fruit tree grafting. The grafting method of the present invention increases the growth space of the callus by leaving grooves on the rootstock, increases the healing area between the scion and the rootstock, and enables the callus to occupy the entire rootstock groove, thereby naturally forming a joint with the scion. The "T-shaped connection" has a strong ability to resist wind or other external forces, and enhances the branch's ability to resist splitting; and the existence of the rootstock groove can hinder but not block the water and nutrient supply of the rootstock, so the humidity in the "rootstock groove" is relatively high. High is not affected by the external temperature, helps the formation and growth of callus, and greatly improves the survival rate of grafting, which can reach 100%.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, and in particular relates to a chestnut tree grafting method. Background technique [0002] Chestnut (C.mollisima Blume) is native to China and is a unique precious resource in my country. With its excellent quality of "fragrant, sweet and waxy", it has long occupied a dominant position in the domestic and foreign markets and is a traditional export commodity in my country. At present, my country's chestnut cultivation area and output are growing rapidly year by year. In 2018, my country's chestnut output accounted for about 84% of the world's total output, ranking first in the world. Chestnuts are mostly planted in mountainous and hilly areas with poor site conditions and inconvenient transportation. Affected by multiple factors such as site conditions, traffic conditions, and scattered operations, most chestnut orchards are not standardized in construction and irregular in appearan...

AI Technical Summary

Problems solved by technology

Most chestnut orchards have been transforming these low-yield trees through grafting technology, aiming to achieve high and stable yields and improve quality and efficiency. However, the non-standard grafting technology and the low survival rate of grafting lead to insignificant effects

Chestnut tree grafting usually adopts a variety of methods such as woody budding, cutting grafting, skin grafting, and subcutaneous abdominal grafting. Not resistant to branch splitting after grafting, and the survival rate is low
