Embodiment 1

[0012] Embodiment 1, the method for this ash tree grafting Mandshurica mandshurica is carried out according to the following steps: the first step, the cultivation of ash rootstock seedlings, adopts 1-year-old ash rootstock seedlings to carry out field planting in spring, and the plant spacing is 38cm to 40cm, and the row spacing is 68cm to 40cm. 70cm, plant 2,800 to 2,850 plants per mu; the second step is to graft the ash tree to Fraxinus Fraxinus, and the ash tree to graft Fraxinus Fraxinus adopts the method of bud grafting. From April 15th to 20th in the spring of the following year, cut off the 1-year-old branches with xylem The buds of the Fraxinus ash scion with full bud eyes are then grafted on the white wax rootstock seedlings at a distance of 5cm to 8cm from the ground. When grafting, they are tied with a bandage to expose the buds of the Fraxinus ash scion. The trunk above the scion interface is cut off, and the cut is sealed with wax; the third step, the management a...

Embodiment 2

[0014] Embodiment 2, the method for this ash tree grafting Mandshurica mandshurica is carried out according to the following steps: the first step, the cultivation of ash rootstock seedlings, adopts 1-year-old ash rootstock seedlings in spring to carry out field planting, the plant spacing is 38cm or 40cm, and the row spacing is 68cm or 70cm, plant 2800 or 2850 plants per mu; the second step, ash tree grafted Fraxinus mandshurica, ash tree grafted Fraxinus mandshurica adopts the method of bud grafting, on April 15 or 20 in the spring of the following year, cut off the 1-year-old branches with xylem The buds of the Fraxinus ash scion with full bud eyes are then grafted on the ash rootstock seedlings at a distance of 5cm or 8cm from the ground. When grafting, they are tied with a bandage to expose the buds of the ash scion. After the grafting, the ash rootstock The trunk above the scion interface is cut off, and the cut is sealed with wax; the third step, the management after gra...

Embodiment 3

[0015] Embodiment 3, as the optimization of the above-mentioned embodiment, the post-grafting management is carried out as follows: after 7 days of grafting, check the survival situation, if the grafting is not alive, carry out supplementary grafting; after 10 days of germination, the bandages should be removed. Post-grafting management is an important measure to increase the rate of grafting seedlings. First, check the survival situation. After 7 days of grafting, the petiole of the bud will fall off when touched by hand, and the skin color of the bud is bright green, which proves that the grafting is alive; If the color is black and the buds are dry, the grafting has not survived, and it needs to be repaired. The second is to cut the anvil, the height is 2cm from the top of the bud, and the cut should be smooth and inclined at an angle of 45 degrees; the third is to untie and germinate for 10 days Finally, the straps should be removed, because the ash grows fast after germina...

Abstract

The invention relates to the technical filed of grafting and provides a method for grafting fraxinus mandshurica on fraxinus chinensis. The method is implemented according to the following steps: step 1, cultivation of fraxinus chinensis rootstock seedlings: one-year-old fraxinus chinensis rootstock seedlings are planted in a field in spring, and 2,800-2,850 seedlings are planted per mu; step 2, grafting of the fraxinus mandshurica on the fraxinus chinensis: the fraxinus mandshurica is grafted on the fraxinus chinensis with a bud grafting method, on April 15 or 20 in the spring of next year, buds of fraxinus mandshurica scions of one-year-old branches with xylem and full bud eyes are cut and grafted on the positions, 5-8 cm away from the ground, of the fraxinus chinensis rootstock seedlings, a bandage is used for binding during grafting, buds of the fraxinus mandshurica scions are exposed, main stems above ports of the fraxinus mandshurica scions are cut off after grafting, and cut edges are sealed with wax; step 3, management after grafting: normal management is performed after grafting. Compared with the conventional grafting technology, the method for grafting the fraxinus mandshurica on the fraxinus chinensis is high in survival rate, economical and practical and can meet afforestation demands.

Description

technical field [0001] The invention relates to the technical field of grafting, and relates to a method for grafting ash tree to mandshurica mandshurica. Background technique [0002] Mandshurica mandshurica belongs to Oleaceae, up to 30 meters, diameter at breast height can reach more than 1 meter; the bark is gray, the bark of young trees is smooth, and there are longitudinal cracks of alternate thickness after maturity; branchlets are slightly quadrangular, glabrous, and bark hole. Odd-pinnate compound leaves, opposite, 25 cm to 30 cm long, rachis grooved, with very narrow wings; leaflets 7-11 (13), sessile or subsessile, ovate-oblong or elliptic lanceolate, (5) 8-14 (16) cm long, 2 cm-5 cm wide, smooth end long acuminate, base cuneate, asymmetrical, sharply serrated on edge, glabrous or sparsely hirsute above, below Yellow-brown bristles are sparsely grown along the leaf veins, and yellow-brown hairs are densely grown at the joints of leaflets and leaf rachis. Dioeci...
