1 Seedlings choose to grow robust, no pests and diseases, root integrity, full of buds more than 3 high quality seedlings, the prohibition of the use of "small old seedlings", planting seedlings every other year. 2 In the year of the plastic pruning and colonization, when the new shoots grow to 25 centimeters, leave 2 branches with better growth and remove other branches. When the shoot reaches 40 centimeters in length, it is attached to a temporary wooden stick, and the subtip is left with 1 to 2 leaves repeatedly. When the beginning of autumn, the topping will be extended. .50 meters. For the two-year-old plant, when it is cut in summer, it should be removed when the shoot length reaches 10 cm. The shoots should be removed when they reach a height of 25 cm. The main vines per meter should retain 5-6 new shoots. More than 60 cm above the ground can stay 2--3 ears; when cutting in winter, according to dry dragon plastic, short tips prune every 1 meter to retain 3 - 4 retention fruit mother branch, extension branch clipping 1.50--2 Meters around. Three-year-old plants, branches are basically covered with planes. When cutting in the summer, the new shoots reach the height of 25 cm, and the main vines per meter retain five to six shoots, of which three to four result branches, two vegetative shoots; 3--4 result branches. After the branches and vegetative branches are dropped, the growth point should be removed, and the apron should retain one leaf topping. At the same time, the winter buds and summer buds between the secondary shoots and the buds should be gently removed with nails. 3 The flower and fruit management early eradicate the inflorescence, and the extension of the vine can retain 2 - 3 ear, and the rest results in branching of the single ear. At the same time, remove the shoulder and tip. Spray 0.30% borax plus 0.30% urea before flowering. The sparsely fertilized small fruit pieces, deformed grains, and overly dense fruit grains were sparsely removed, and the lower part of the ear was removed by 1/3--1/4, and about 3 weeks after flowering, the grape leavening agent was added with thiophanate-methyl (or a subtilisin). Dip the ear or spray the ear. When the bulking agent and bactericide are used, the ear should be timely bagged, and the bag should be removed about 20 days before harvesting, and the ears should be turned to achieve uniform color. 4 Fertilizer and water management After the fruit is harvested every year, 3,000 kg of organic fertilizer plus basal fertilizer plus superphosphate are applied deep into each acre immediately. Grapes should be soaked with winter water before leaving the grapes. Before sprouting the following year, with irrigation water, Mushi urea 20 kg (precipitating fertilizer); inflorescence appeared before flowering 1--2 times; into the fruit expansion period, topdressing 20 kg of diamine per acre (flowering fertilizer), At the same time, water irrigation, hard core period topped with 25 kg of compound fertilizer per acre, while irrigation; from mid-August to the harvest of fruits, the leaves were sprayed with 0.30% of potassium dihydrogen phosphate 3- 4 times (urgent Color fertilizer) to promote the ripening of fruits and shoots and to control the whole garden. 5 Pest control Before the grape is unloaded, spray the 3--5 degree Baume lime sulfur mixture with 0.50% sodium pentachlorophenolate mixture to disinfect the whole garden. The prevention and control of downy mildew and powdery mildew are carried out every year from June to August. Especially in the case of high plant density, high temperature and high humidity, the plants must be observed at any time for early control.
