Abstract

The invention discloses a process for grafting eggplants for grafting eggplant to ingraftment by using tomatoes as stock, the operational method is easy, the seedling after grafting can be applied to sequential cropping cultivation, wherein the result can be increased by 20%-30% as compared with other grafting methods.

Description

A kind of grafting method of eggplant

Technical field

The present invention relates to a kind of grafting method of eggplant.

Background technology

Eggplant sequential cropping cultivation, its verticillium wilt, the fusarium wilt incidence of disease have become the major obstacle of restriction eggplant development up to 30%～50%.Now both at home and abroad by research, adopt the strong wild eggplant rootstock of disease resistance to carry out grafting cultivation mostly, solved the difficult problem of eggplant continuous cropping and soil-borne disease, its growth shows as that opening degree is big, blade is little, percentage of fertile fruit is high, but grow thin and weak, fruit is modest, gloss difference, output and quality all decrease.

Summary of the invention

But the grafting method that the purpose of this invention is to provide a kind of sequential cropping cultivation, growth is vigorous, blade is plump, percentage of fertile fruit is high, fruit gloss is bright-coloured, output is higher eggplant.

For achieving the above object, technical scheme of the present invention is: a kind of grafting method of eggplant is to be stock with the tomato, the grafting guinea squash scion.

As a kind of improvement, described is stock with the tomato, and the method for grafting guinea squash scion adopts inarching method, and its concrete processing step is as follows: when the tomato rootstock seedling has 4～6 true leaves, eggplant scion seedling gets final product grafting when having 3～6 true leaves; The tomato stock is cut sth. askew 30 °～55 ° downwards from 4～7cm more than the ground, and the grafting guinea squash scion is upwards cut sth. askew 30 °～55 °, grafting guinea squash scion and tomato stock angular cut are coincide, and the grafting interface after will engaging is fixed with Grafting clip; Plant in grow seedlings bed or the nutritive cube after the rice shoot grafting and water sufficient water, and cultivate with the plastic canopy heat and moisture preserving, day temperature should be controlled at 28 ℃～32 ℃, nocturnal temperature should be controlled at 18 ℃～25 ℃, and relative moisture is after grafting in 85%～95%, 8～12 days survives substantially, this moment, wound healed, desirable Grafting clip down changes normal management over to, suitably increase illumination and reduce space humidity, further tempers rice shoot; The grafting processing of can being completely cured in 15～18 days is promptly chopped the rhizome under the eggplant grafting mouth off and is pulled out, and chops the above cauline leaf of tomato grafting mouth simultaneously off; Be portable the 20 days summers of rice shoot after the grafting, and be portable 25～30 days winters.

As a kind of improvement, described is stock with the tomato, and the method for grafting guinea squash scion adopts cleft graft, and its concrete processing step is as follows: when the tomato rootstock seedling has 4～6 true leaves, eggplant scion seedling gets final product grafting when having 3～6 true leaves; The stock base portion is from 4～7cm transversely cutting more than the ground, from the stem center to incision to 1.0cm～2.0cm degree of depth, with eggplant scion bottom wedging, 1～3 true leaf is stayed in scion, then eggplant scion bottom is inserted in the otch of tomato stock, it is coincide, and fix with Grafting clip, plant in grow seedlings bed or the nutritive cube after the rice shoot grafting and water sufficient water, and cultivate with the plastic canopy heat and moisture preserving, day temperature should be controlled at 28 ℃～32 ℃, and nocturnal temperature should be controlled at 18 ℃～25 ℃, relative moisture is 85%～95%, after grafting in 8～12 days survived substantially, this moment, wound healed, and desirable Grafting clip down changes normal management over to, to suitably increase illumination and reduce space humidity, further temper rice shoot; Be portable the 20 days summers of rice shoot after the grafting, and be portable 25～30 days winters.

Owing to adopt technique scheme, a kind of grafting method of eggplant is to be stock with the tomato, the grafting guinea squash scion, method of operating is simple, but the rice shoot sequential cropping cultivation after the grafting and grow vigorous, blade is plump, percentage of fertile fruit is high, fruit gloss is bright-coloured, output is higher, improve more than 20%～30% than other grafting method, have great economic benefit and social benefit.

Embodiment

Embodiment 1: a kind of grafting method of eggplant is a stock with the tomato, and inarching method is adopted in the grafting guinea squash scion, and its concrete processing step is as follows:

When the tomato rootstock seedling has 4～6 true leaves, eggplant scion seedling gets final product grafting when having 3～6 true leaves; Grafting will be carried out under fine day shelters from heat or light condition, and the stock otch is selected in from more than the ground between 4～7cm, otch from top to bottom, 30 °～55 ° degree of angle, tiltedly the degree of depth be stem thick 1/2.Then scion band root is tripped out, cut sth. askew from bottom to top at the position that scion and stock otch are complementary, tiltedly the degree of depth be stem thick 1/2, ligulate otch with scion inserts in the otch of stock then, the two is overlapped, fix with Grafting clip immediately, after connecing grafting is placed in the nutritive cube ridging and waters, be placed on immediately in the little shed that shelters from heat or light.Plant in grow seedlings bed or the nutritive cube after the rice shoot grafting and water sufficient water, and cultivate with the plastic canopy heat and moisture preserving, day temperature should be controlled at 28 ℃～32 ℃, nocturnal temperature should be controlled at 18 ℃～25 ℃, and relative moisture is after grafting in 85%～95%, 8～12 days survives substantially, this moment, wound healed, desirable Grafting clip down changes normal management over to, suitably increase illumination and reduce space humidity, further tempers rice shoot; The grafting processing of can being completely cured in 15～18 days is promptly chopped the rhizome under the eggplant grafting mouth off and is pulled out, and chops the above cauline leaf of tomato grafting mouth simultaneously off; Be portable the 20 days summers of rice shoot after the grafting, and be portable 25～30 days winters.

Embodiment 2: be stock with the tomato, cleft graft is adopted in the grafting guinea squash scion, and its concrete processing step is as follows:
