Problems solved by technology

[0003] Although it has been reported to sow and raise seedlings of the red-winged Acer, the germination rate is relatively low, and the germination rate of conventional sowing is about 48.5%. It is of great significance to graft the spikes, cultivate excellent clone seedlings, and preserve excellent germplasm

Embodiment 1

[0045] A red-winged maple grafting method specifically includes the following steps.

[0046] (1) Rootstock cultivation: adopt the nutrient bag seedling raising technology to carry out the cultivation of the red-winged maple seedlings, and the diameter obtained at the main stem height 20-30cm place is 0.6-0.8cm red-winged maple seedlings as the rootstock.

[0047] (2) Preparation before grafting: 0.3% compound fertilizer nutrient solution containing nitrogen, phosphorus and potassium (N:P:K=16:16:16) was applied to the rootstock one month before grafting.

[0048] (3) stock making: the stock is cut flat, and the top of the stock is 20cm away from the rhizome, and the incisions 1 and 2 with a depth of 2.0 cm are made downward from the top of the stock.

[0049](4) selection of scion: select excellent individual plant without pests and diseases, full bud branch as scion, branch stem is about 0.4cm thick, the branch is cut into scion of length 3cm, each scion contains at least 1 ...

Embodiment 2

[0059] A red-winged maple grafting method specifically includes the following steps.

[0060] (1) Rootstock cultivation: adopt the nutrient bag seedling raising technology to carry out the cultivation of the red-winged maple seedlings, and the diameter obtained at the main stem height 20-30cm place is 0.6-0.8cm red-winged maple seedlings as the rootstock.

[0061] (2) Preparation before grafting: 0.5% compound fertilizer nutrient solution containing nitrogen, phosphorus and potassium (N:P:K=16:16:16) was applied to the rootstock one month before grafting.

[0062] (3) stock making: the stock is cut flat, and the top of the stock is 25cm away from the rhizome, and the incisions 1 and 2 with a depth of 1.8 cm are made downward from the top of the stock.

[0063] (4) selection of scion: select excellent individual plant without pests and diseases and full of buds as scion, branch stem is about 0.6cm thick, the branch is cut into scion of length 4cm, each scion contains at least 1...

Abstract

The invention discloses an acer fabri Hance grafting method for the first time. The method specifically comprises steps of stock cultivation, preparation before grafting, stock production, scion selection, scion treatment, grafting and management after grafting. By means of the acer fabri Hance grafting method, acer fabri Hance scions with excellent characteristics such as good growth and development and unique flower types and flower colors can be grafted on stocks, and acer fabri Hance grafted plants can keep excellent traits of stock plants with an asexual propagation method. The grafting success rate is high, and the whole method is easy to master and has good development prospects.

Description

technical field [0001] The invention relates to the field of seedling planting, and more particularly to a method for grafting red-winged maple. Background technique [0002] red-winged maple ( Acer fabri Hance) is an evergreen tree of the Aceraceae family, with a height of 10-15m and a DBH of 30cm. It is one of the native tree species in southern my country. It is naturally distributed in Fujian, Guangdong, Guangxi, Jiangxi, Hunan, Hubei, Sichuan and other places in my country. It grows in dense forests at an altitude of 300-1800m. Red-winged maple is highly adaptable, prefers deep, loose and fertile soil, can grow in acidic or slightly alkaline soil, and can also grow in drier and poorer soil conditions. Red-winged maple is also an excellent landscape tree species newly discovered. It is resistant to shade and cold. It is the most ideal configuration for the second layer of canopy. Viewing leaves in four seasons, fruit viewing in summer and autumn, green leaves and brig...
