1, summer black has strong growth potential, good flower bud differentiation, and full branches can also produce flower heads. The leaves are erect, dark green and have high photosynthetic efficiency.
The cultivation management is easy and the cultivation effect is better.
2. Young trees adopt "T-frame with high, wide and vertical". In addition, summer black is also suitable for greenhouse cultivation.
3. Digging ditches and fertilizing before planting, with plant spacing1m.. After planting, thoroughly irrigate the root water and cover it with plastic film.
4. Erase the double buds, multi-head buds and over-weak buds after germination; After the new tip is formed, tie iron wires on both sides and fix the tip with the spacing of 15 ~ 20 cm. ?
5. From budding to early flowering, the extra-large panicles and weak panicles should be sparse. ?
6. The fruit setting rate of Xiahei is very high. One week before flowering, you should take off the accessory spike and several supporting shafts under it, gently pinch the spike tip or even keep it.
Tapered ears. Fruit thinning is stable after falling flowers and fruits. ?
7. When soaking the swelling agent for the first time, tie the main branch ring with a width of 2 ~ 3 mm to the xylem, and then bandage the wound with adhesive tape.
It can promote the increase of fruit particles. When berries are first colored, they can ripen early.
8. Generally, fully decomposed chicken manure or cake fertilizer should be applied in time after flowering, with 200 kilograms per mu and 30 kilograms of ternary compound fertilizer and potassium sulfate.
10kg, apply twice.
Extended data:
Growth habits of summer black grapes:?
The plant grows vigorously, and the germination rate of bud eye reaches 85%. The branching rate is 95%, and each bearing branch has an average of 1.5 inflorescences. Does the bud branch of the hidden bud bear fruit?
Strong and productive. It germinates in late March, blooms in mid-May, and matures in late July, from flowering to fruiting.
It takes about 1 10 days to mature, and it is an early-maturing seedless variety. Strong disease resistance, fruit does not crack or drop seeds after ripening.
