Embodiment 1

[0025] Use the annual hardened branches of the mature Cotoneaster seedlings as the scion, and use the Vitex seedlings with a thoracic stem of 5 cm as the rootstock, and graft the scions on the 4-year-old Vitex seedlings, and the grafting interface is selected at a height of 1.5 meters.

[0026] Mountain Vitex (Malus baccata)

[0027] [Form] Arbor, more than 10 meters high. The branches are thin and weak, the leaves are oval-elliptic, and the leaf margins are finely serrated. The flowers are white, 4 to 7 flowers form a corymb, and the pedicels are slender. The flowering period is from April to May. The fruit is nearly spherical, red, and the fruit period is September-October, and the fruit lasts for a long time.

[0028] [Ecology] Light-loving, more shade-tolerant, cold-resistant, and drought-tolerant.

[0029] [Distribution] Produced in North China, Northwest and Northeast China.

[0030] [Cultivation] Seed propagation. After the seeds are stored in sand at 1-5°C for 30...

Embodiment 2

[0044] The difference from Example 1 is:

[0045] Use the annual hardened branch of the mature Cotoneaster seedling as the scion, and use the Vitex seedling with a breast stem of 8 cm as the rootstock, graft the scion on the 5-year-old Vitex seedling, and the grafting interface is selected at a height of 1.8 meters. Described grafting method is skin insertion, and skin insertion grafting method is carried out after the seedlings are peeled off from the end of April to the beginning of May:

[0046] 1) The cutting of the scion, the scion is taken before it germinates in early spring, and stored at a low temperature. The low temperature storage condition is that the temperature is at 3°C, and the two ends are sealed with a wax seal in wet sand;

[0047] 2) For grafting, cut the scion into a 2 cm beveled surface, and cut it into a 1 cm small beveled surface on the back, leaving 2 buds on the scion, then cut off at the joint on the rootstock, and then make a longitudinal cut on th...

Embodiment 3

[0049] The difference from Example 1 is:

[0050] Use the annual hardened branches of the mature cotoneaster seedlings as the scion, and use the hawthorn seedling with a thoracic stem of 6 cm as the rootstock, and graft the scion on the 7-year-old hawthorn seedling, and the grafting interface is selected at a height of 1.6 meters.

[0051] Hawthorn (Crataegus pinnatifida Bge.)

[0052] [morphology] small tree, up to 6 meters. Bark gray or taupe. Leaves triangular, ovate or diamond-shaped ovate, base truncate to broadly cuneate, apex shortly acuminate, with 3-7 pinnatifids, margin heavily serrate. The flowers are white, and many flowers form corymbs, and the flowering period is in May. The fruit is nearly spherical, 1-1.5 cm in diameter, bright red, and the fruiting period is September.

[0053] [Ecology] Light-loving, slightly shade-tolerant, cold-resistant, drought-resistant and barren. The root system is developed and the sprouting ability is strong.

[0054] [Distribu...

Abstract

The invention refers to a graft-seedling growing technique, concretely a method to graft Cotoneaster multiflorus Bunge on arbor, using annual hardening branch of mature Cotoneaster multiflorus Bunge nursery-grown plant as cion, and haw or M.baccata nursery-grown plant as stock, and grafting the cion on the stock, grafting interface selected at the height of 1.5-1.8m. It can reduce cost.

Description

technical field [0001] The invention relates to grafting seedling raising technology, in particular to a method for grafting Cotoneaster multifiorus on trees such as Crataegus pinnatifida and Malus baccata. Background technique [0002] Cotoneaster multifiorus is a deciduous shrub, with slender branches, often bow-shaped and curved, reddish-brown branchlets, linear stipules, falling off; leaves ovate, glabrous on the surface, numerous flowers, about 5-21 flowers in loose cymes Inflorescence; petals flat, white; fruit nearly spherical, about 8mm in diameter, red, flowering period from May to June, fruiting period from August to November, light-loving and slightly shade-tolerant, relatively cold-resistant, extremely resistant to drought and barrenness, colorful flowers and fruits, There are many red fruits in autumn, and they will not wither for a long time. It is an excellent flower and fruit tree species. It is suitable for planting in gardens, parks, houses, and lawns. It c...
