Ruby Grape High Yield Cultivation Techniques
Ruby grapes are a late-ripening seedless grape variety with strong growth potential and a high germination rate. They usually start bearing fruit in the second year after planting and are adaptable. They have no strict requirements for soil, fertilizer, and water, and have good economic benefits. To achieve high yields of Ruby grapes, cultivation techniques are very important. Let's take a look at the high-yield cultivation techniques of Ruby grapes with the editor.
Planting
Since seedlings may lose water during storage and transportation in winter, it is necessary to soak the seedlings to ensure they absorb enough water and improve their survival rate. Planting usually occurs between March and April. After planting,葡萄 vines are watered on raised beds, and 0.35 kg of acetamide herbicide is sprayed per mu. When covering with film and planting cuttings, ensure the buds are level with the ground and not pressed by the film. Cover them with a small soil mound. In about half a month, the buds naturally grow out from the back of the small mound.
Pruning
For one-year-old seedlings, when the grape vines grow to about 40 cm, it's time to pinch the tips. At the same time, prune the tendrils and keep the three main vines tied up in time. In winter, each branch should have 6-7 full buds, and the rest should be cut off. For two-year-old seedlings, keep about 10 fruiting branches, tie the vines to the trellis, prune the tendrils, and pinch the tips during the full bloom period. Also, keep one secondary branch for each main branch. In winter, keep 4-5 fruiting mother branches per branch, with 3-5 full buds on each. Seedlings older than three years should be pruned the same as two-year-old seedlings.
Fertilization and Water Management
In addition to applying organic fertilizer before planting, 25 grams of potassium sulfate compound fertilizer is applied per seedling in mid-June, and 2 kg of organic fertilizer is applied per seedling in October, supplemented with an appropriate amount of phosphorus fertilizer. For two-year-old seedlings, apply 100 kg of NPK compound fertilizer per mu before germination, apply potassium fertilizer from June to July, apply organic fertilizer after harvest in autumn, supplemented with an appropriate amount of nitrogen and phosphorus fertilizers, and then determine the amount of fertilizer according to the number of fruits. Moreover, before the grapes germinate, it is necessary to apply fertilizer and a large amount of water. In early winter, it is necessary to pour a cup of frozen water. In summer and autumn, the frequency of watering should be determined according to the weather. During the rainy season, attention should be paid to drainage.
Fruit Bagging
Ruby grapes are a high-end fruit, and to improve quality, bagging should be used. The bagging time should be about two weeks after planting, and an appropriate bagging method should be chosen. Before bagging, spray a fungicide and insecticide once, and wait for the liquid to dry before bagging.
