Chestnut tree groove-reserving type grafting method

Abstract

The invention provides a chestnut tree groove-reserving type grafting method, and relates to the technical field of fruit tree grafting. According to the grafting method disclosed by the invention, the growth space of the callus is increased by reserving the groove in the rootstock, the healing area of the scion and the rootstock is increased, and the callus can fully occupy the whole rootstock groove, so that a T-shaped connection is naturally formed between the callus and the scion, the wind resistance or other external force resistance is stronger, and the branch splitting resistance is enhanced; moreover, due to the existence of the rootstock groove, the water and nutrition supply of the rootstock can be hindered but not blocked, so that the humidity in the rootstock groove is relatively high and is not influenced by the external air temperature, the formation and growth of calluses are facilitated, and the grafting survival rate is greatly improved and 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
