This variety belongs to Eurasian species, and its leaves are divided into five parts, the upper part is deep and the lower part is shallow, with medium size, and the back of the adult leaves is hairy and rough. Its fruiting branch rate is 95%, germination rate is 9%, and its natural fruit setting ability is strong. The ear of the fruit is more compact at the 3rd-4th leaf, and the weight of a single ear is 5-75g. The fruit is slender, the top of the fruit is extremely sharp, the natural single fruit weighs 9-11g, the meat is hard and crisp, each fruit contains 1-2 seeds, the peel is thin, and the sugar content is 25-29%. The fruit will be listed in early September, and if it is not picked, it will not fall off until the middle and late October, and the color of the fruit will also change from early-ripening pink to bright red or even purple.
first, planting. In the north, the temperature rises above 5℃ after autumn and before the soil is frozen or in spring, and in the south, after the autumn leaves fall, it will last until February of the following year. In view of the vigorous growth of red milk, in order to produce high-quality fruit, it is suggested to adopt hedge scaffolding in both north and south. According to the determined row direction and row spacing, a planting ditch is dug in the middle of the border with a width of 5-7cm and a depth of 35-8cm, and weeds and perishable straws are placed at the bottom of the ditch. Apply fertilizer into the ditch, and apply 4-5 cubic meters of pig manure, 3-4 cubic meters of sheep manure, or 2 cubic meters of decomposed chicken manure with 1 kilograms of phosphate fertilizer per mu, and mix well with the soil. Fill the topsoil in the middle and lower parts, and cover the surface with the lower soil. Plant spacing: .7m× 3m in the north, with 33 plants planted per mu; The south is .7m× 3m, and 33 plants are planted per mu. Water the soil immediately after planting to make it solid.
second, post-planting management. Erase the rootstock tiller buds in time, select the strong grafted buds as the main vines, erase the redundant buds and pull the wires vertically in time to make the seedlings stand upright. One-year-old seedlings should be watered frequently. In winter cutting, it should be noted that the diameter of the cutting mouth 1 meter from the ground should not be less than 1 cm, and the diameter of the side branch below 1 meter and above 5 cm can reach 1 cm, which can be used as the bearing branch in the second year. Two-year-old seedling management: (1) after excavation, before germination, irrigation with water for accelerating germination combined with fertilization. ⑵ Wipe the buds in time, and the principle is to remove the weak and stay strong. ⑶ Fixed shoot: When the new shoots grow to 5-1cm, it is advisable to keep 1-15 shoots per square meter of the shelf surface or keep the distance between the new shoots at 25-3cm. ⑷ Watering: water with fertilization 7-1 days before flowering, water with fertilization 1-15 days after flowering, watering with small water every 1 days before fruit growth and grape coloring. 5. Picking the new shoots: about 7 days before flowering, leave 1 leaves on the inflorescence and 12 leaves on the developing branches for pinching. [6] Secondary shoot treatment: leave 1-2 secondary shoots at the top of the fruiting mother branch, erase the rest, leave 2-3 leaves at the top secondary shoot for coring, and leave 1 leaf at the developing branch for repeated coring. (7) fruit bagging: spraying bactericide 7-1 days after flower falling, bagging can be done the next day, and bagging is completed within 2 days after flower falling. (8) Pruning in winter: generally, it is carried out after defoliation to the following spring. When pruning in winter, the thickness of fruiting branches should not be less than .8 cm, and the cutting mouth should be 3-5 cm in front of buds. Short, medium and short shoots can be pruned, or a combination of long, medium and short shoots can be used for pruning. ⑼ Burying soil for cold protection: generally, it is covered with soil for cold protection 1-15 days after winter shearing and before soil freezing. In the Yangtze River valley or the south of the Yangtze River, after pruning in winter, the trees are sprayed with 1-3 degrees of stone-sulfur mixture.
