Summer black grape cultivation technology complete set where there is?

What are the advantages of summer black grape? How to manage the summer black grape? Is there a complete collection of summer black grape planting techniques? Also ask netizens to guide the summer black grape, also known as summer black seedless, oriental black pearl, is an excellent variety with many advantages in one body, with disease resistance, high yield, very early maturity, easy coloring, resistance to storage and transportation, high sugar content, good taste; planting network sorted out the planting techniques and management methods of summer black grape, which are listed below for netizens' reference. The advantages of Xiahei grape are as follows: first, the ear of Xiahei grape is conical or cylindrical. After hormone treatment, the ear generally weighs 600-900g, and the maximum weight is 1600g. The fruit is round, compact and neatly arranged, 8 ~ 10g after expansion. Combined with fruit thinning and sufficient fertilizer and water application in two expansion periods, the average grain weight can reach 1011g. The second advantage is that the summer black grape has strong stress resistance and is resistant to storage and transportation, the growth of summer black is similar to the giant peak. Cultivated in the same garden with Jufeng, Fujiminori, Gao wife and Giant Rose, the resistance was better than that of the above varieties and slightly lower than that of Xiangyue. The summer black skin is thick, and it is not easy to break due to extrusion in the process of transportation. It has high sugar content and is more resistant to storage and transportation than ordinary varieties. In addition, after the fruit is ripe, it can be hung on the tree for more than 60 days without cracking, dropping grains or changing color. Third, the flower bud differentiation of Xiahei grape is good and stable, and the germination rate of bud eye is more than 85%. Each fruiting shoot has an average of 1.5 ears. The garden was established in the first year and can be put into production in the second year, and the highest yield per 667m2 can reach 2250kg. Advantage 4, summer black grape is very early ripening, easy to color, high sugar high summer black from sprouting to fruit ripening 100-105 days. Combined with spraying acid pesticide for 3 times and spraying foliar fertilizer containing medium and trace elements for 5 times, after the fruit begins to soften, spraying grape early ripening and sugar will appear on the market 7-10 days in advance, which can greatly improve the commodity value. Many grape varieties delay the harvest time because of difficult or uneven coloring, affecting the commodity value. Summer black is not the case, the berries soften, that is, quickly colored, and the coloring is fast and uniform. At present, the sugar content of precocious grapes is mostly 15-18 degrees, which is sold on the market, including Jufeng, mostly at 13-15 degrees, with a general taste. Under general management conditions, Xiahei can reach 20,22 degrees, with a maximum of 24 degrees. Many people call Xiahei "super sweet grapes". Main points of planting and management of Xiahei grape: the planting method of Xiahei grape: Xiahei grape is most suitable for hedge cultivation, natural fan-shaped pruning, row spacing 1.7m, plant spacing 0.8m 667 m2 to plant 500 plants. In the area where the soil should be buried to prevent cold, 420 plants can be planted with a row spacing of 2m and a plant spacing of 0.8m 667m2. Where there is a lot of rain, the first wire above the ground is more than 80cm away from the ground to prevent rain splashing and sediment pollution. This type of frame is beneficial to make full use of land, wind and light, especially for early high yield and general management level, and the output of 667m2 can reach more than 2000kg in the second year. Key points of management 1, timely ear trimming and fruit thinning: summer black grape ear neat, more non-ambiguous shoulder, individual double ear. It is suggested that if there are two ears, one should be repaired. If the ear is too long, the ear tip should be removed 10 days before flowering. On average, there is only one ear per fruiting branch, and in practice, according to the principle of "strong two and one weak", that is, two ears can be left on the top (front end) of the shelf, one ear on the medium growth shoot, and no ear on the weak branch and culture branch. The total number of ears left per 667m2 is about 4000. The seeds of summer black fruit are closely planted, so it is recommended that the fruit be thinned. Artificial fruit thinning, time-consuming, can be in full bloom fruit-setting period to drink water, or combined with fungicides, consciously spray the ear to promote its moderate drop. Or shake or hit the tree moderately during the flowering and fruit setting period, which can also play the role of thinning flowers and fruits. Management points 2, timely expansion of the ear: because in the domestic grape market, consumers still prefer large-grain grapes. The enlargement of grape fruit is beneficial to increase yield and improve commodity value. Xiahei grape grows naturally and the fruit is small, which is the commonness of seedless grapes, so it is recommended to carry out expansion treatment. That is, 15 days after flowering, 45~50mg/kg gibberellin solution was dipped or sprayed on the ear, and repeated every 12 to 15 days. Or when the grains of soybeans are large, use 45mg/kg gibberellin solution to spray or dip in the ear for each 1~1.5kg to increase the yield of 10ml (inhibiting pedicel hardener). Management essentials 3. Bagging grape ears: grape bagging has many benefits, such as disease prevention, pest prevention, bird pest prevention, pollution prevention, yield protection and quality protection. The berries produced are not only beautiful, but also taste good. It is suggested that whether it is field production or greenhouse cultivation, strive for a full set of bags. Management point 4: fertilization and watering of summer black grape: it is suggested that organic matter fertilizer should be re-applied in the production of summer black grape. During the planting and establishment of the garden, organic fertilizer 5000kg was applied per 667m2, and then expanded outward along one side of the planting ditch every other year, organic fertilizer was applied once in the ditch, and 4000~5000kg was applied per 667m2. In spring, grapes can be topped with quick-acting nitrogen fertilizer for one time to promote sprouting and large ears. The expansion fertilizer was applied once with high nitrogen ternary fertilizer. Apply potash fertilizer once before fruit ripening. If the amount of fertilizer is not good, it should be decided according to the soil fertility, yield and tree potential. Management point 5: winter pruning: winter pruning is very important and is directly related to the yield of grapes in the following year. Xiahei grape has good flower bud differentiation, high germination rate and high fruiting branch rate. Therefore, the general tree potential is mainly short shoot pruning, while strong branches can be pruned in the middle. The adult orchard with natural fan-shaped pruning is cultivated by hedgerow, and it is suggested that 667m2 should keep 15001800 fruiting branches.
