1. Planting ruby grapes Because the seedlings will be short of water during storage and transportation in winter, they need to be soaked to taste enough water and improve the survival rate. Generally planted in March-April. Grape trimming irrigation, 1 mu spraying acetochlor 0.35KG for weeding. After covering with plastic film, the upper bud is flush with the ground, and the seedlings should not be squeezed by plastic film, but should be covered with a small mound. Generally, after ten days, the small mound will be flat, and the seedlings will of course come out.

2. Pruning and bundling of grapes are aimed at annual seedlings. When the grape branch grows to 40cm, the red heart picture should be collected as soon as possible. At the same time, the tendrils are trimmed to mink color, leaving three main tendrils, which are bound immediately. In winter, each branch should have 6-7 round buds and the rest should be cut off. Two-year-old seedlings are left with 10 upper and lower fruit branches, bound with tendrils, trimmed with tendrils, topped at flowering stage, each branch is left with 1 secondary branch, and 4-5 fruiting branches are left in winter, each branch has 3-5 full buds. The nursery base of about 3 years is the same as the green seedlings of 2 years.

3. Fertilizer and water management methods Except applying organic fertilizer before planting, 25 grams of potassium sulfate compound fertilizer was applied to the annual seedlings in the middle and late June, 2 kilograms of organic fertilizer was applied to each seedling in June 5438+ 10, and appropriate amount of phosphorus and potassium fertilizer was added. Before 2-year-old seedlings germinate, NPK compound fertilizer 1 00 kg/mu, potassium fertilizer in June-July, organic fertilizer in autumn after obtaining, and appropriate NPK fertilizer, and then determine the amount of fertilization according to the number of conclusions. In addition, the grapes should be watered once with fertilizer before germination and once with ice water in early winter. The watering frequency should be clear according to the temperature in autumn and winter, and pay attention to the drainage pipeline during the rain period.

Grapes should be bagged with fruits. Ruby grape is a high-grade fruit. In order to improve its quality, fruit bagging should be carried out after 2 weeks, and the choice of fruit bagging should be as far as possible. Pesticide, bactericide and insecticide should be sprayed once before sealing the bag, and then the bag should be sealed after the medicine is dried.

Ruby grapes are rich in growth and development, so shed or Y-shaped hedge should be used to trim the middle and short tips. This kind of ear is beautiful and elegant, with high quality, but the fruit is a little small, so auxin and girdling can be used to increase the fruit size. Ruby grape is weak in disease resistance and late in perfection, especially susceptible to black pox and downy mildew, so attention should be paid to prevention as soon as possible in production and manufacturing. Its stalks and pedicels are slightly brittle, so be careful when picking them.
