Hedge frames are mostly used in the north, and V-shaped or scaffolding frames are mostly used in the south. Generally speaking, hedgerows are more suitable for cultivation. When planting grapes, for areas that need to be buried in the ground for cold protection, the row spacing can be 2 meters, the plant spacing can be 0.8 meters, and 6,300 grapes can be cultivated per hectare. Under the general management level, the output of the second crop can reach more than 30 thousand kilograms per hectare.

Step 2 trim ears and thin fruits

Suggested pruning of summer black grape with ears 1. If the ear is too long, pinch off the ear tip 1/5 ~ 1/4 10 days before flowering. On average, only 1 ear is left on each fruit branch, 1 ear is left on the new shoots with medium growth, and no ear is left on the weak branches and cultured branches. Artificial fruit thinning can be done by watering with small water at full flowering stage and fruit setting stage, or spraying fungicides.

3. Expansion treatment

Summer black grapes grow naturally, with small fruit grains, which need to be expanded, which is beneficial to increase grape production and improve commodity value.

4, fruit bagging

Bagging grapes can prevent diseases and insect pests, bird damage, pollution and so on. Therefore, it is necessary to bag whether it is planted in the open field or in the greenhouse.

5. Water and fertilizer management

Organic fertilizer should be applied again in the production of summer black grapes. When planting the garden, apply organic fertilizer 1500~2000 kg per mu, apply organic fertilizer 1 times per mu 1500 kg per mu, and apply effective nitrogen fertilizer 1 times in spring to accelerate germination and promote the growth of large fruit ears. Apply 1 times high nitrogen ternary fertilizer at the expansion stage, and apply 1 times potassium fertilizer before the fruit matures.

6. Scientific winter scissors

Summer black grape has good flower bud differentiation, high germination rate and high fruiting branch rate. Therefore, pruning is mainly based on short branches, and strong branches can be trimmed in the middle. Generally, there are 22,500 ~ 27,000 fruiting branches per hectare.

Extended data:

Characteristics of Summer Black Grape:

1, strong resistance

Summer black grape is cultivated in the same garden as Kyoho, Fujiminori, Gao Qi and Jugui, and its stress resistance is better than these varieties.

2, high yield

The bud eye germination rate of Xiahei grape is 85%, and the flower bud differentiation is good and stable. Generally, the park will be built in 1 year and put into production in the second year.

3, easy to color

Summer black grapes can be quickly colored after the berries are softened, which is not only fast but also uniform.

4. Very precocious

Summer black grapes need 100- 105 days from germination to fruit maturity, spraying foliar fertilizer containing medium and trace elements for 3-5 times, and spraying 1 time after fruit softening, which can be marketed 7- 10 days in advance.
