High-position grafting method of choerospondias axillaries tree

Abstract

The invention relates to the field of rapid breeding and seed replacing technology of a choerospondias axillaries tree, in particular to a high-position grafting method of the choerospondias axillaries tree. A wild choerospondias axillaries tree or a not good strain of choerospondias axillaries tree with the age of 3-10 years is adopted as a stock, an exuberant fruited mother branch which grows for a year and is provided with plump buds is collected from a seed choerospondias axillaries tree of a good strain and serves as a high-position grafting scion, and grafting is carried out through the processes of stock cutting, scion peeling, binding of the stock and the scion, shade removal, stock coating, core picking, fertilizer application, film release and the like. The choerospondias axillaries tree after high-position grafting can have fruits and can reach a high yield period after 3-4 years, and the production time of good choerospondias axillaries is largely shortened.

Description

technical field [0001] The invention relates to the technical field of rapid breeding and replanting of wild jujube, in particular to a method for high-position grafting of wild jujube. Background technique [0002] Southern jujube (Choeros Pondias axillaris Burtt.), also known as jujube, five-eyed fruit, etc., is a deciduous tree of the genus Jujube in the family Anacardiaceae. It is mainly distributed in Jiangxi, Fujian, Hunan, Guangxi, Guangdong, Hubei, Zhejiang, and Guizhou in the south of the Yangtze River Basin. In other provinces, southern wild jujube wood has straight and beautiful texture, slightly rough structure, light and soft material, easy processing, medium strength, no cracking after drying, red heartwood, strong corrosion resistance, and is widely used in construction, shipbuilding, furniture, flooring, plywood, Excellent material for decoration. Stem bark contains fiber and can be used to make rope and paper, and bark and branches are rich in tannins. The...

Problems solved by technology

At present, the existing methods of grafting the southern wild jujube tree all adopt the seedlings of the southern wild jujube tree that have been cultivated for one year as the rootstock, and carry out grafting in the spring, and after grafting, they will be tended for one year to emerge from the nursery. After planting, the seedlings of the wild jujube tree will start to bear fruit in the fourth year, and it will take 5 days before and after. - It takes 6 years to bear fruit, and 9-10 years to enter the high-yield period, so it is difficult to obtain economic benefits quickly
