Isn t grafted eggplant suitable for open air cultivation?

OK. Eggplant grafting technology mainly uses wild eggplant plants as rootstocks for eggplant grafting, and grafts eggplant seedlings on the rootstock. Grafted seedlings have the advantages of high yield, disease prevention, and improved resistance and quality.

Eggplant grafting seedling technology is relatively strong, labor-intensive, seedling cost is higher, coupled with the current eggplant grafting rootstock variety is small, difficult to purchase, and the incidence degree of eggplant soil-borne disease is not as serious as watermelon, melon and other reasons, the current eggplant grafting cultivation scale in China is obviously not as large as watermelon, cucumber and melon.

Due to the perennial continuous cropping, all kinds of diseases are relatively serious, and the use rate of grafting cultivation technology is also relatively high, and the grafting cultivation rate is close to 100% in the severely diseased area. Due to the short cultivation time, suitable for intercropping, and low incidence, grafting cultivation technology is rarely used in the open field eggplant cultivation area.

In the long run, with the continuous expansion of the production scale of eggplant protected areas and the continuous improvement of the degree of specialized production of eggplant, the disease prevention grafting and cultivation technology of eggplant will receive more and more attention, and the grafting technology will also become one of the indispensable measures for the cultivation of eggplant protected areas in winter and spring.

The splitting method, a more common method used in eggplant grafting, has a high survival rate and high grafting efficiency. When the autumn seedlings of rootstock and scion grow to 5 6 true leaves, cut the upper part of the rootstock stem horizontally with a blade, keep 2 3 true leaves, split a 1 cm deep incision vertically in the middle of the rootstock stem, and then pull out the scion eggplant seedlings, remove the lower end at the place where the eggplant seedling stem is purple and black and green obviously, remove the lower end, keep 3 4 true leaves, cut into a wedge, the wedge size is equivalent to the rootstock incision (1 cm long), then insert the scion into the incision of the rootstock, fix it with a special grafting clip after alignment, and support it with a special thin bamboo stick, Prevent lodging.

In the grafting method, the rootstock and scion are grafted when they have 3 or 4 true leaves. The method is to select the rootstock incision between the second and third leaves, remove the leaves from the base, the incision from top to bottom, the angle is 30 ° 40 °, the scion is taken out with the root, moisturize, and the blade is used to cut the leaves from the base at 3 4 true leaves, and then cut the incision about 1 cm long from the stem at a 30 ° 40 ° inclination, and then make the rootstock and the scion two inclined planes opposite each other and pinch them with clamps.

In the plugging method, grafting is carried out when the rootstock seedlings have 5 6 true leaves and the scion has 2 or 3 true leaves. When grafting, the rootstock leaves 1 3 true leaves to remove the upper part with a blade cross-cutting, and pierces a hole about 1 cm deep with a bamboo skewer slightly inclined downward. Cut the stem into a wedge-shaped incision of 6 8 mm under the cotyledons of the scion seedlings and insert the scion incision into the small hole of the rootstock face down.

Summary. One is the place, it is best to carry out in the greenhouse or greenhouse, try to avoid sand, rain or livestock and poultry pollution The second is the knife, the razor used in grafting must be sharp, generally about 150 plants on each side of the blade grafting should be replaced in time The third is disinfection, the operator's hands and grafting knives should be disinfected with wine essence or potassium permanganate solution many times in the grafting process to avoid cross-infection of germs. At the same time, it should be noted that after disinfection, the hands and blades should not be touched until they are dried, otherwise it will be difficult for the incision to heal after being stained with water or liquid.

What problems should be paid attention to in eggplant grafting cultivation? Why?

Hello, I have seen your question and am sorting out the answer, please wait a while

What happens when a grafted eggplant grows two leaves of different shapes during its growth? Is it normal? What is the reason?

Is it a curly leaf? Hello, there are many reasons why the same plant grows different leaves: such as different levels of light, radiation, parasitism by parasitic plants, etc.!

It is common for the underground roots to be connected with the underground roots of other plants (natural grafting), so that the plant retains both the leaves of the original plant and the characteristics of the grafted leaves.

This is normal.

It is due to grafting.

No. There are two strains that grow with different leaf shapes, one is turquoise and the other is purple.

One seedling grows two plants, the stems are different, and the leaves are not the same.

That should be a matter of grafting.

Summary. Eggplant can be grafted with tomatoes, peppers, potatoes, bell peppers and other plants of the same genus.

Eggplant can be grafted with tomatoes, peppers, potatoes, bell peppers and other plants of the same genus.

These plants all belong to the Solanaceae family and have a strong kinship, so they can be grafted with each other.

When grafting, healthy plants and suitable grafting methods should be selected to improve the success rate of grafting. At the same time, the grafted eggplant also needs to pay attention to management, maintain a suitable growth environment and management measures, so as to obtain better yield and cherry kernel in the product.

If you want to plant grafted eggplant, you need to first cultivate rootstock and scion in the past generations, the rootstock is suitable for Torubam, red eggplant and other plants, plant rootstock 7-10 days in advance, and then plant eggplant scion, when the rootstock has 5-6 true leaves, you can graft the scion up, and plant after grafting, pay attention to the first three days should not let its ventilation limbs slowly see the light.

1. Cultivate rootstocks

If you want to plant grafted eggplant, then you must first cultivate the rootstock, generally use Torubam, red eggplant, etc. as rootstocks, and sow the rootstock into the seedbed soil 7-10 days in advance, pay attention to the need to dry the seeds before sowing, and then soak and germinate, so that the rootstock can germinate and grow quickly.

2. Cultivate scion

When cultivating rootstocks, it is necessary to cultivate scion in time, soak and germinate the seeds of eggplant, and wait until the seeds are white, sow them into the seedbed soil, which can be mixed with garden soil, rotten horse manure and manure in a ratio of 5:4:1, and need to be disinfected before use.

3. Grafting method

When the rootstock grows to 5-6 true leaves, it can be grafted, dig it out, remove the upper part of the rootstock, and then split the centimeter from the stem, and then take out the eggplant and return the core ear seedlings, retain 2-3 true leaves, and cut it into a centimeter-long wedge-shaped surface, and then align and insert it into the rootstock and fix it.

4. Planting and maintenance

After grafting, you can plant the plant into the soil, and then water from the bottom of the plant to keep the soil slightly moist, three days before grafting do not need ventilation and light, the humidity is about 85%, the temperature is 20-26 is the best, and then gradually ventilate and see the light, and soon the two can heal and grow together.

1.The difference between grafted eggplant and regular eggplant.

Grafted eggplant and regular eggplant are two different varieties of eggplant. Through grafting, the growth rate and yield of eggplants can be increased, and it can also prevent diseases and improve the environment. Compared with ordinary eggplant, grafted eggplant has the following differences. Imperial Pose.

2.Grafted eggplants grow fast.

Compared with ordinary eggplant, grafted eggplant can promote the growth and development of the root system, enhance the ability of the root system to absorb nutrients, and accelerate the growth rate of the plant due to the grafting with the rootstock. Therefore, under the same maintenance environment, the growth cycle and yield of grafted eggplant will be faster than that of ordinary eggplant.

3.Grafted eggplant has strong disease resistance.

The bacterial infection of the rootstock of grafted eggplant will not be transmitted to the stem and fruit of grafted eggplant, so as to effectively improve the resistance of grafted eggplant to pathogens, reduce the probability of disease occurrence, and increase the yield and quality of eggplant.

4.Grafted eggplant is of better quality.

Grafted eggplant Through the selection of rootstocks and the management of the grafting process, you can choose excellent rootstocks and high-quality eggplant varieties from Youzhen, and graft the two together to get better quality and taste. Compared with ordinary eggplant, grafted eggplant is more tender, more delicate in taste, and more nutritious.

5.Grafted eggplant is highly adaptable to the environment.

Grafted eggplant has the characteristics of strong adaptability, which can tolerate lower temperatures, worse soil, worse light, etc. than ordinary eggplant. Therefore, in the case of harsh environment, grafted eggplant is more adaptable and easier to survive.

6.Advantages of ordinary eggplant.

Although ordinary eggplant does not have as many advantages as grafted eggplant, it also has its unique advantages. Ordinary eggplant is easy to grow, low cost, does not require complex grafting operations and management, and can simply rely on artificial or natural growth to obtain a certain yield.

7.Grafted eggplant is difficult to grow.

Due to the complex steps such as rootstock selection, grafting process and later management, grafting eggplant is more difficult to grow than ordinary eggplant. Without the guidance and support of professional and technical personnel, there are certain risks in the planting efficiency and success rate of grafted eggplant.

8.Summary.

Based on the above comparison, grafted eggplant and ordinary eggplant have their own advantages and disadvantages. For ordinary consumers, if they want to use a simpler and more convenient way to grow, they can choose ordinary eggplant; If you want to go for a higher yield, higher quality and better taste, you can choose to graft eggplant, but it is best to consult with a professional before planting.
