Problems solved by technology

Taking advantage of the developed root system, strong adaptability and fixed rate of Robinia pseudoacacia, it is a good method to graft Qinshengxianghuacai to Robinia pseudoacacia trees, but the existing tree grafting technology is difficult to master the grafting method and slow grafting speed , the survival rate is less than half of the problem

Embodiment 1

[0010] In winter, cut off the branches of the annual, robustly growing Sophora japonica, and store them in sand under natural conditions in the wild. In May of the next year, take out the branches from the sand storage, soak them in water for 24 hours, and then cut the branches to keep For the branches of 1-2 buds, seal the cut wound with paraffin, and use it as a scion for later use.

[0011] When the annual Robinia pseudoacacia seedlings start to germinate, except for the 1cm height left on the ground as the rootstock, cut off all others, cut the lower end of the scion into a horse-ear shape, and then use the tip of the knife to cut the cortex of the rootstock to the left and right on the windward side of the rootstock. Pry off the cortex on both sides, insert the cut scion with the large slope facing the xylem of the rootstock into the rootstock cortex, insert it at one time until the large slope of the scion is no longer white, tie it with plastic tape, germinate after abou...

Embodiment 2

[0013] The scion preparation of Qinsheng Fragrant Sophora japonica is the same as in Example 1.

[0014] Transplant the 1-2-year-old black locust in spring. After germination in May, cut off the 1cm above the black locust with a pair of scissors and use it as a rootstock. It germinates in about 30 days and blooms in about 30 days.

Embodiment 3

[0016] The scion preparation of Qinsheng Fragrant Sophora japonica is the same as in Example 1.

[0017] After germination in May, cut off the perennial black locust tree where there are branches, leaving 0.5-3.0cm thick branches, cut off the smooth part of the branch skin as a rootstock, and cut the lower end of the scion preserved in winter. Horse-ear-shaped, inserted into the smooth cortex of the rootstock at one time, bound with plastic tape, it can grow into an engineering tree in one year, and bloom in the second year.

Abstract

The invention discloses a method for grafting winter branches of Robinia pseudoacacia in summer. The method comprises the following steps of: (1) cutting one-year-old branches of Robinia pseudoacacia in winter, and carrying out sand storage under field natural conditions; (2) taking out sand-stored branches in next May, soaking in water for 20-24 hours, then cutting into branch segments with 1-2 buds, and sealing the cut with paraffin to be used as scion; and (3) at the time of grafting, cutting or sawing germinated acacia to be used as rootstock, cutting the lower end of the scion into a horse-ear-shaped large slope, then clinging to the wind facing side of the rootstock, prying the skin layer of the rootstock with a knife or hand, inserting the scion to the skin layer of the rootstock at one time while controlling the cut large slope of the scion faces the xylem of the rootstock until the large slope of the scion is not exposed, and then binding with plastic belts. The grafting method disclosed by the invention has the advantages that: skin layer alignment is not required in the grafting insertion process; the operation is especially easy; the grafting method is very simple; the grafting survival rate can reach more than 98%; and the grafting efficiency is very high and is improved by more than four times than that of the existing grafting method.

Description

technical field [0001] The invention relates to the grafting technology of horticultural plants, in particular to a method for grafting in summer using winter branches of sophora japonica of Qinsheng fragrant flowers. Background technique [0002] Sophora japonica, also known as the rich tree, blooms twice a year. A string of red flowers is extremely gorgeous in color, fragrant and elegant, unique, and has high ornamental value. Qinsheng Xianghuahuacai is a new species of leguminous Sophora deciduous arbor originally produced in Qinyuan, Shanxi Province. Qinsheng Xianghuahuacai is a bud variety selected from the callus of local Robinia pseudoacacia and Xianghuahuahua, and has been approved by the State Forestry Administration New breed certification. Qinshengxianghuahuacai grows into a tree with a plant height of 10-15 meters. The leaves are oily green and the flowers are pink or purple. It blooms twice a year in May and July in the cold northern regions. It blooms continuo...
