The red grape has a large ear, good uniformity, an average single grain weight of 10 grams, fruit red or purple, thick skin, easy to peel, solid and brittle meat, juicy and sweet, delicious and delicious. In recent years, Jiawang District of Xuzhou City has introduced this variety of planting, and has achieved good economic benefits. Now, the high-quality and high-yielding cultivation techniques of its solar greenhouse are summarized as follows.

Before planting, planting trenches with a depth of 1.8m and a width of 0.8m will be prepared for planting, and the excavated raw soil and mature soil will be piled separately and exposed for 3 days. Backfill 10 cm thick wheat straw or corn stalks on the ditch bottom pad, spread 10 cm thick mature soil, and then fully fill the cooked soil, fully cooked manure, and fine sand in a ratio of 1:1:1. Into, 40 centimeters thick, above the 10 cm thick mature soil to fill the groove, apply 2 kg of calcium phosphate per ditch, then cover the mature soil 10 cm thick, and then irrigated solid ridge colonization, ridge height 15 cm, wide 80 cm. Planting the shed cover film for about 5 days to increase soil temperature. One day before planting, the roots were soaked in water and soaked for 24 hours. The roots were too long to be trimmed.

Colonization in the planting line every 1.2 meters to dig a planting hole, each hole urea 300 grams, 200 grams of diammonium phosphate. The depth of colonization is preferably 1 to 2 buds into the soil at the base of the shoots. After the planting, the culvert of the ridge is broken up and flattened, the film is 1 meter wide, and the soil is tightly sealed around the soil.

Fertilizer irrigation immediately after planting, water flow to the ridge can be. Cover all the seedlings with soil, remove the soil after the buds have greened, and clean the soil on the ridge. Adhere to moderate, reasonable nitrogen fertilizer, increase the ratio of phosphorus and potassium fertilizers. The basal fertiliser from October to the fall leaves is dominated by fully decomposed organic fertilizers, and nitrogen fertilizer is applied in time during the growing season. A 3% zinc sulfate solution was sprayed before budding, and 0.3% to 0.5% urea and 0.2% to 0.3% potassium dihydrogen phosphate solution were sprayed in the growing season. According to the soil, the microclimate in the greenhouse, and the growth of plants, flexible irrigation.

Temperature regulation For the grape seedlings that are not bagged or buried, in order to ensure the normal germination of the buds, the temperature will be gradually increased after three times of colonization, film coating and irrigation. Specific methods: Put all the grass screen down, the room can not see the light, close the vents, the first 5 days of temperature control at 10 °C; 5 to 10 days, every 3 to 5 curtains to pull up a curtain, the temperature is controlled at 15 °C For 10 to 15 days, one curtain is pulled up every other curtain, and the temperature is controlled at 20°C. After 15 days, when the buds turn green, the curtains are all pulled up, and the temperature is controlled at about 25°C. When the minimum temperature at night is stable above 12°C, the film is removed until it is completely removed in mid-May.

After tree planting, each plant was selected to retain the first shoot with new buds. The new shoots were erected when they were 30-40 cm long, and the shoots of summer buds sprouted in the shoots of new shoots were promptly removed. When the new shoot grows 80 centimeters long, it picks up the heart and retains the top two sub shoots. When the sub shoot length is 50 centimeters, it picks up the heart, and the top 1 or 2 sub shoots leave 2 leaves repeatedly to pick up the heart, so that the main branch accumulates nutrients and promotes the formation of flower buds. During the growth, the tendrils on the shoots are cut off in time. After August, two knives were cut in the second quarter of the resulting branch, separated by 0.5 to 1 cm. In the result period, 10 to 15 leaves were picked in the upper part of the ear, and the secondary shoots were left as they were, and 4 to 5 large leaves were picked as desired.

Flower and fruit management according to the results of branches, vegetative branches for the principle of 1:2 to remove the inflorescence on the vegetative branches, remove the ear tip, so that the inverted trapezoidal ear, ear more crowded when the spike. The small grains, deformed grains, damaged grains and fruit particles that were squeezed tightly and tightly were removed in a timely manner. The spikelets retained 40 to 50, the middle ear remained 51 to 80, and the large ear retained 80 to 100 grains. After bagging, the bags were bagged in time, and the Pleople liquid was sprayed on the ear, and the bag was dried after the liquid was dried. Remove the paper bag 20 days before harvest and turn the ears.

Disease prevention Grape disease mainly includes white rot, anthrax, blackpox, and gray mold, etc., and it should be used for symptomatic drug control.
