Cultivation technology of seedless white chicken heart, key points of cultivation of seedless white

1. Use excellent rootstock grafted seedlings. Such as Huajia No. 8, Betta anvil and so on.

2. In the post-young fruit stage, it was treated with low concentration GA to promote fruit expansion.

3. Hormone treatment after flowering should not be too early, so as to avoid rust of young fruits.

4. Timely and strict thinning of grains in the young fruit stage, leaving about 70 grains per panicle.

5. Timely bagging of young fruits.

String-tapered, tender green, with sparse hairs. The young leaves are reddish and sparsely hairy. 1-year-old shoots are tan, stout, internoded principals.

The adult leaves are large, heart-shaped, 5-lobed, the fissures are extremely deep, the upper lobes are closed, the front and back sides of the leaves are hairy, and the leaf margins are large and sharp. The petiole depression is open and arched.

The fruit spike is conical, with an average spike weight of 1300 grams and a maximum weight of 2500 grams. The fruit is long and oval, with an average grain weight of 10 grams. The peel is yellow-green, the flesh is thick and hard and crisp, the toughness is good, thick and sweet, the peel is not easy to separate, and there is no need to spit out the peel to eat.

Contains soluble shapes, acid, sugar content 13% 28%, slight rose fragrance, excellent quality.

The fruit of the variety is firm, does not fall grains, is resistant to transportation, is not easy to be refrigerated for a long time, and is stored at room temperature for more than 5 days.

The peel is fully ripe and yellow-green, the flesh is hard and brittle, the fruit does not crack, and the soluble solids are about 14%. It is a refreshing crispy meat variety, which promotes the cultivation of Shanghai on July 20-22. It is a medium-ripe seedless variety.

Suitable cultivation area: high temperature and humid areas in southern China, more greenhouses are used to promote cultivation.

The tree is strong, the branches are thick, the fruiting branch rate, the fruiting branch rate can exceed 95% if properly managed, each fruiting branch bears 1 2 fruit spikes, and the double spike rate is more than 30%. The 2-year-old plant yields kilograms. That is, 2 years of good yield.

The yield is high and stable, generally about 1300 kg per mu. The fruit ripens consistently, has strong resistance to frost and limb mildew, and is susceptible to black pox.

The fruit does not split the limbs, does not need to be colored, and can be harvested at one time.

Planted on land, it sprouts in early June in Chaoyang area, Liaoning Province, blooms in early June, and matures in mid-August. It ripens in early September in the Shenyang area.

Greenhouse planting, Shenyang area of Liaoning Province sprouts in February and matures in June, and southern Liaoning region sprouts in late January and matures in mid-May. Late bud break in late January, bloom in early April, and ripen in early June.

The shoots are green with sparse hairs. The young leaves are reddish and sparsely hairy. The 1-year-old shoots are yellowish-brown, stout, and have long internodes.

The adult leaves are large, heart-shaped, 5-lobed, the lobes are extremely deep, the upper lobes are closed, the front and back of the leaves are hairy, and the leaf margins are large and sharp. The petiole depression is open and arched.

The tree is strong and the branches are strong. Fruiting branch rate, each fruiting branch produces 1-2 fruit spikes, and the double spike rate is more than 30%. The 3-year-old plant yields kilograms. High yield. The fruit ripens consistently, has strong resistance to downy mildew, and is susceptible to black pox.

Seedless white chicken heart is also known as Moritani seedless, century seedless Eurasian species. Introduced from the United States, the fruit ear is conical, the spike weight is 400 600g, the fruit is chicken heart-shaped, the peel is yellow-green, tougher, more neat, the commercial grain weight, the flesh is brittle, the tensile pressure resistance is stronger, the quality is medium to high, the soluble solids content is 17 20%, the fruit is ripe, and the yield is relatively high.

Seedless white chicken heart grape is a Eurasian species native to the United States. It was introduced from California, USA in 1983. It is a GOID Q25-6 cross-bred.

After five years of greenhouse cultivation trial observation, the variety showed moderate growth potential in the local area, more fertilizer tolerant, fruiting branch rate of about 40%, fast production, high and stable yield, generally about 1300 kg per mu. The fruit spike is large, the fruit setting rate is high, the fruit is long and oval, seedless, the background color of the peel is green, light yellow when ripe, the natural grain weight is 4-5 grams, the average grain weight is 8-10 grams after hormone treatment, the weight of each spike is 700-1200 grams, and the maximum can reach 2500 grams. The peel is thin, the toughness is good, the fruit does not crack, the flesh is thick and hard and crisp, can be cut into thin slices, the soluble solids are 14%-16%, the acidity is low, the strawberry fragrance is slightly, the peel is not easy to separate, it can be eaten with the skin, it is fragrant and refreshing13, and the quality is good.

Medium storage and transportation resistance, weak disease resistance, medium-ripe varieties. Through years of cultivation, a set of high-quality cultivation technical measures for the purpose of promoting flower bud differentiation, stabilizing yield and increasing fruit grains have been explored and summarized in accordance with the standard requirements of green food production.
