Introduction to genuine Sunshine Rose grape seedlings (authenticity and price of Sunshine Rose grape seedlings)

Introduction to Sunshine Rose Grape

The fruit cluster is conical, with a cluster weight of about 600 grams, and a large cluster can reach about 1,800 grams. The average fruit weight is 8 to 12 grams. The fruits are densely attached, oval, yellow-green, shiny on the surface, and little powder.

Its flesh is crisp and juicy with a rose scent. The soluble solids content is around 20%, and can be as high as 26%. The fresh food quality is excellent.

Generally, the yield of Sunshine Rose is about 1,200 kg/mu. This variety can be treated with 25 ppm gibberellin during the flowering period and 10-15 days after flowering to make the fruit seedless and increase the weight of the fruit by about 1 gram.

The plant grows vigorously and is very productive after long-shoot pruning. Short-shoot pruning can also be performed. Under rain-sheltered cultivation conditions, the buds in Jiangsu Province generally sprout in mid-to-early March, enter the initial flowering period in early May, and bloom in early to mid-May. The first young fruit swells in early June, the fruit begins to change color in mid-July, and begins to mature in early August .

Compared with Kyoho, this variety is easier to cultivate, has a longer fruiting period, and can bear fruit on the tree for up to 2 to 3 months after maturity; the fruit does not crack, is resistant to storage and transportation, and has no threshing phenomenon; it is more resistant to grape white rot, downy mildew and powdery mildew, but not resistant to grape anthracnose.

Grape seedling price : At present, the price of Sunshine Rose is not high this year, with self-rooted seedlings at around 3 yuan and grafted seedlings at around 3.5 yuan to 5 yuan.

How to tell if Sunshine Rose grape seedlings are real or fake

The appearance of the Sunshine Rose grape seedlings is somewhat different from others. The new leaves are white and have a lot of hairs, which is different from other varieties.

The new shoots of other varieties are light green or light red, but the new leaves of Sunshine Rose are white, then grow into red-green, yellow-green, and finally dark green when they become adult leaves.

At present, Sunshine Rose is more concerned about the selection of grafted rootstocks rather than the identification of seedlings, which usually include Beda, 5BB, SO4, etc.

In actual planting in the north, the performance of the Beda rootstock is still good. It is frost-resistant and has a more vigorous root system, so the tree is more vigorous and the virus symptoms are milder. Just be sure to ask clearly when purchasing.

Planting technology of Sunshine Rose grape seedlings

Sunshine Rose grape seedlings are one of the newly introduced varieties in Japan. They are European and American varieties. They are disease-resistant, high-yielding, and have large and delicious fruits. They mature in early August. They have beautiful appearance and rich fragrance. They are particularly resistant to transportation. After they are fully mature, they can bear fruit for 2 months. They are currently a very good mid-ripening variety and can replace Victoria grape seedlings. Here is a brief introduction to the planting method of Sunshine Rose:

Digging trenches

Generally, the main direction is north-south, and the distance between the two trenches is 2.8~3m. The depth is 0.4~06m and the width is 0.8~1m.

Fertilization

(1) Organic fertilizer is mainly used and applied in layers. First, rice straw, weeds or corn stalks are applied to the bottom layer, followed by decomposed livestock manure (such as pig, chicken, and sheep manure), not less than 5,000 kg per mu, and about 75 kg of superphosphate.

(2) If there are many underground pests in the planting area, you can add some pesticides. When planting, the roots of the grapes should be more than 30 cm away from the fertilizer.

(3) Grape planting should also be based on region and grape variety, and should be based on the unique habits of the grape variety.

Planting Spacing

The number of seedlings planted is generally 220~238 per mu, with a row spacing of 2.8~3m and a plant spacing of 1m. (Southern trellis) The number of seedlings planted is generally 460~600 per mu, with a row spacing of 1.5m~1.8 and a plant spacing of 70~80cm
