Embodiment 1

[0021] In the middle and late March, select 1-2-year-old catalpas, open at 1.2-1.5m above the ground, use Lingxiao as the scion, graft the two together, tie them up, and coat the joint with mud or liquid paraffin; the buds survive Finally, keep 1-3 pieces of axillary buds on the rootstock, and wipe off the rest; until the healing is firm, remove the binding tape on the rootstock, cut off the stumps and lower rootstock buds, and add fertilizer at the same time.

[0022] The grafting method is the T-shaped bud grafting method: cut a knife at 0.4cm above the bud, reach the xylem, and then push up from shallow to deep with the bud grafting knife from the bottom of the bud 1.5cm, reaching one-third of the xylem , pry the knife upwards, and pick up the shield-shaped bud piece; then press the anvil to obliquely, cut a 1.2-1.5cm horizontal cut across the cortex, and draw a 1cm vertical downward knife edge under the middle of the horizontal cut, and take advantage of the situation to co...

Embodiment 2

[0025] In the first ten days of October, select 1-2 year old catalpas, open at 1.2-1.5m above the ground, use Lingxiao as the scion, graft the two together, tie them up, and coat the interface with mud or liquid paraffin; after the buds survive , keep 1-3 pieces of axillary buds on the rootstock, and wipe off the rest; until the healing is firm, remove the binding tape on the rootstock, cut off the stumps and lower rootstock buds, and add fertilizer at the same time.

[0026] The grafting method is the T-shaped bud grafting method: cut a knife at 0.4cm above the bud, reach the xylem, and then push up from shallow to deep with the bud grafting knife from the bottom of the bud 1.5cm, reaching one-third of the xylem , pry the knife upwards, and pick up the shield-shaped bud piece; then press the anvil to obliquely, cut a 1.2-1.5cm horizontal cut across the cortex, and draw a 1cm vertical downward knife edge under the middle of the horizontal cut, and take advantage of the situatio...

Embodiment 3

[0029] In the middle and late March, select 1-2-year-old catalpas, open at 1.2-1.5m above the ground, use Lingxiao as the scion, graft the two together, tie them up, and coat the joint with mud or liquid paraffin; the buds survive Finally, keep 1-3 pieces of axillary buds on the rootstock, and wipe off the rest; until the healing is firm, remove the binding tape on the rootstock, cut off the stumps and lower rootstock buds, and add fertilizer at the same time.

[0030] The method of grafting is the abdominal grafting method: first cut a knife obliquely on the back of the lower bud of the scion, the cut side is about 1.5-2cm long, into a horse-shaped shape, and then beveled on the other side 0.3cm-0.5cm long, into a wedge shape, and then cut on the rootstock Cut obliquely, about 1.5cm-2cm long, and reach 1 / 3 or 1 / 2 of the current year's branches. Quickly insert the scion into the cut of the rootstock so that the cambiums of the two are aligned with each other, and then wrap it t...

Abstract

The invention relates to a method for lignifying campsis grandiflora. The method comprises the following steps that a catalpa tree which is 1-2 years old is selected; an opening is formed in the portion, 1.2-1.5 m above the ground, of the selected catalpa tree; the campsis grandiflora is used as a scion, the campsis grandiflora is grafted onto the catalpa tree, the campsis grandiflora is bonded to the catalpa tree, and the joint is coated with mud or liquid paraffin; after the scion survives, 1-3 axillary buds are retained on a stock, and the rest is removed; a binding strap on the stock is released when the opening is healed and grows firm, a stump and stock on the lower portion are cut out, and fertilizer is applied additionally. The campsis grandiflora lignified by the adoption of the method is high in survival rate and beautiful in posture.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to the technical field of plant grafting. Background technique [0002] Campsis grandiflora (Thunb.) Schum. of Bignoniaceae. Climbing vines; the stems are woody, the epidermis is shed, withered brown, and they climb on other things with aerial roots. Leaves opposite, odd-pinnate compound leaves; needle-shaped, apex caudate-acuminate, base broadly cuneate, sides unequal, 3-6(-9) cm long, 1.5-3(-5) cm wide, Lateral veins 6-7 pairs, glabrous on both sides, coarsely serrated at margin; rachis 4-13 cm long; petiole 5(-10) mm long. Terminal scattered short panicle, inflorescence rachis 15-20 cm long. Calyx campanulate, 3 cm long, split to middle, lobes lanceolate, about 1.5 cm long. The inner surface of the corolla is bright red, the outer surface is orange-yellow, about 5 cm long, and the lobes are semicircular. Stamens inserted near the base of the corolla tube, filaments li...
