What kind of grape seedlings is good?

1. Sunshine rose grape

Light rose grape has high yield, stable yield, large grain, disease resistance, good storability and simple cultivation. The ear is conical, the ear weight is about 600g, the large ear is about 1.8kg, and the average grain weight is 812g. The fruit is compact, oval, yellowish green, glossy and less powdered. The flesh is crisp and juicy with rose scent.

two。 Kyoho Grape

Jufeng grape is one of the main varieties in production, which has strong adaptability, good disease resistance, cold resistance and like fertilizer and water.

Mature in late August, purple-black when ripe, thick pericarp, more fruit powder, soft pulp, sweet, juicy, strawberry flavor, easy separation of skin, meat and seeds, sugar content of 16%.

3. Summer black grape

Xiahei grape is an excellent variety, which has the characteristics of disease resistance, high yield, early maturity, storage resistance, good taste and so on. Its young branches are yellowish green, the leaves are large, light green, and densely hairy. Most 4-lobed, margin serrate. The mature buds are reddish brown, and the winter buds are big and full.

4. Sapphire grape

Sapphire is a medium-ripe variety, mature in the open field from August to September, does not drop grains, does not rot after maturity, hang trees for more than one month, and is resistant to storage and transportation. The fruit color is blue and black, and the coloring is fast and uniform. Knife cut into slices, pure flavor, crisp sweet without residue, soluble solids more than 20%, dry areas with higher sugar content, easy to turn into large blue-black raisins.

Second, what are the methods of raising grape seedlings?

1. Raising seedlings

Cuttings should be stored last winter, thawed and cut into cuttings 25cm and 30cm long. The cut at the upper end of the ear should be flat, 1-1.5 cm from the bud, and the lower cut should be horseshoe-shaped. Tie 50 cuttings into a bundle and soak them in water for 24 hours. The nursery land was irrigated before cutting, applying basic fertilizer 4000kg to 5000kg per mu, deep ploughing fine rake. Ridge cuttings take root earlier and seedlings grow faster than flat bed cuttings.

two。 Raising seedlings

Raise seedlings with extra sprouting tillers or vines on the plant. Striping should be carried out before and after the ambush, generally using the new tip crimping in the same year, called green branch crimping. The sprouting branches growing at the base of the plant can also be selected to make the secondary shoots grow upright, grow new roots on the lower nodes, and break into independent plants when the secondary shoots mature in autumn, that is, into striped seedlings.

3. Raising seedlings

Grafting can be carried out in both dormant and growing periods. Tongue grafting is often used in dormant period. Grafting can be carried out in spring and summer during the growing period. The grafted materials use hard branches in spring and green branches in summer. The grafting methods were split grafting and cutting grafting respectively.

The main results are as follows: (1) the collection and winter storage of rootstocks and scions, grape grape scions and rootstocks should be selected to grow sturdy, disease-free, mature and full branches. The storage method of dormant strips of rootstocks and scions in winter is the same as that of cuttings.

(2) tongue grafting and split grafting are often used in grafting. Cutting: according to the requirements of grafting, select the branches with similar thickness, soak them in clear water for 24 hours and cut them into rootstocks about 30 cm long, with a scion length of 5 cm and 10 cm, with a full bud.

The scion is generally cut 1-2 cm above the full bud and flat-cut 4-5 cm below the bud. The branches of the rootstock are cut flat at 4cm above the terminal bud and about 1cm near the rootstock node at the lower end.

Use a cutter to split vertically down in the center of the rootstock, 3cm to 4cm deep, and cut off the bud holes on the rootstock. Then cut down into a wedge on both sides of 0.5 cm below the scion bud with a splice knife. The bevel is required to be smooth and straight.

Split the upper end of the rootstock longitudinally with a cutter, and then insert the cut scion into the incision of the rootstock (at least one side of the cambium is aligned with the cambium of the rootstock). The cutting surface of the scion shows 1mm and 2mm on the split of the rootstock, which is called whitening, which is beneficial to the formation of callus.

Then use a plastic strip that is 1cm wide and 20cm 25cm long and spirally bind it upward from the bottom of the cut on the rootstock, or seal it with wax.

4. Raising seedlings in nutrition bag

Grape nutrition bowl seedling, also known as container seedling, it integrates the advantages of various seedling techniques, and is a commonly used seedling method in production. Grape nutrition bowl seedling cultivation has the advantages of high survival rate, convenient transportation, easy transplanting and so on.

Cutting cutting and soaking in water should be carried out 40-50 days before grape planting, and the method is the same as that of ordinary cuttage. Rooting treatment: you can use the method described in the first section, or you can use rooting agent to touch the root.

The preparation method of nutritious soil was as follows: 6-7 parts of garden soil, 1-2 parts of mature organic fertilizer, 2-3 parts of peat soil or fine sand, a small amount of cruller and phosphate fertilizer, sifted and mixed well. Disinfect with iron pot or medicine to kill eggs and grass seeds.

Rooting agent treatment: the cuttings before cutting were treated with ABT rooting powder 300x solution, and the rooting effect was better. Cutting: first open a ditch to make a bed (you can also use a greenhouse), 100 cm wide and 120 cm wide and 25 cm deep.

Film covering and management: wooden pole is used to make plastic arch shed, the temperature in the shed is controlled at 25 ℃ ~ 30 ℃, the relative humidity should be above 80%, and it should be watered once every 7 to 10 days. After sprouting and spreading leaves, gradually uncover the film and remove the arch shed.

Packing and transportation: put in wooden or plastic boxes, prevent inversion during shipment, cover with tarpaulins on the way to reduce water evaporation; sprinkle water once a day to prevent seedlings from losing water and wilting. When loading and unloading, handle it gently to prevent root damage of seedlings.

To sum up, it is the variety recommendation of grape seedlings and the methods of raising seedlings. Let's take a look at what you think is good, you can refer to and learn.
