Embodiment 1

[0021] Embodiment 1 (carried out in Baima Town, Lishui, Jiangsu Province)

[0022] In late August, choose a healthy and disease-free branch with full new buds, cut a bud from the branch, with a little or no xylem, as a scion; choose a 3-year-old tree that grows well outdoors and grow rabbit-eye blueberry, from From June, apply fertilizer and water to its roots regularly (add water to the broken bones, bean cakes, rice washing water, bean curd residue, fish head and fish scales, etc. and put them in the tank to rot, add water to dilute when applying) for top dressing, so that it can reserve enough nutrients , and then select a branch with a diameter of 0.5 cm as the rootstock, and spray the whole plant with thiophanate-methyl for disinfection; use a sharp knife to cut the selected rootstock into a "T"-shaped scion mouth from top to bottom and horizontally, and the depth can reach the xylem , the diameter of the cross section is 0.3-0.4 cm, and the length is 2 cm up and down; th...

Embodiment 2

[0024] Embodiment 2 technology of the present invention compares with common grafting method

[0025] In late August, choose healthy and disease-free branches with full new buds, remove the parts that are not full at the tip and base, cut the branches into 8-10 cm long scions with 2-3 buds, and cut the buds from the scion to 3 cm. The two sides of the lower end of the plant are cut into 2-3 cm long wedge-shaped slopes, and the scion surface is smooth and smooth; choose a 3-year-old rabbit-eye blueberry that grows well outdoors, and apply fertilizer and water to its roots regularly from June onwards ( Put broken bones, bean cakes, rice washing water, bean curd residue, fish head and fish scales, etc. into the tank to rot, add water to dilute) for top dressing, let it reserve enough nutrients, and then select branches with a diameter of 0.5 cm as rootstocks , and spray thiophanate-methyl on the whole plant for disinfection; put the scion surface and the rootstock cleft close tog...

Embodiment 3

[0026] Embodiment 3 process of the present invention obtains new plant and former plant characteristic comparison

[0027] The soil pH value of the test site in Baima Town, Lishui, Jiangsu Province was 5.4, and 50 new plants and 50 southern highbush blueberries were planted through the present invention. After planting for one year, all the new plants survived, and only 20 southern highbush blueberries survived; new The fruit obtained by the plant has small seeds and good taste.
