First, the preparation before planting

1. Selection of solar greenhouse: both the newly-built second-generation solar greenhouse and the original vegetable growing greenhouse can be built. Wall base 1.8m, wall top 1.4m, column height 3.79m, southwest 5-8 degrees, length 50-80m, greenhouse span 7-9m, and scaffolding adopts all-steel frame.

2. Rack and planting density: Generally, grape planting in greenhouse is north-south, with one-arm hedgerow and one-arm pruning, with plant spacing of 0.8m and row spacing of1.8m..

3. Marking: Mark with the line spacing of1.8m. ..

4. Fertilization and soil replacement. Before planting, dig a fertilizing ditch with a depth of 0.8m and a width of 0.8m, pile raw soil and cooked soil separately, and expose them in the sun for 3 days to raise the soil temperature. When backfilling, put 10cm of wheat straw or corn straw at the bottom of the ditch, and put 10cm of ripe soil on it. Then, one-third of the ripe soil, one-third of the fully decomposed farm manure (cow manure and sheep manure) and fine sand are fully mixed and filled into 40 cm, and 2 kg of calcium superphosphate or diammonium phosphate is applied to each ditch, and the soil is cooked with 10cm.

5, ridging: ridging after changing the soil. Those who don't fertilize and change the soil can start ridging and plant them on the ridge. The ridge is15cm high and 80cm wide.

6. Cover the greenhouse film before planting, and raise the temperature for about 5 days to increase the soil temperature in the greenhouse.

Second, seedling preparation

1. Suitable varieties: Red grapes are the main varieties planted in autumn, and the fruits can be listed from New Year's Day to Spring Festival. The varieties planted in early spring are Jufeng, Zana, Jingya, Jingxiu and Fufu Rosa, and the fruits can be listed from May 1 day to June 1 day.

2. Soaking: One day before planting, the roots of grape seedlings are soaked in water for 24 hours to fully absorb the water, and the seeds can be planted the next day.

3. Pruning root system: The root system of grape seedlings is too long, so it should be pruned with the length of 10- 15cm.

Third, planting

1. Planting time: generally from mid-April to early May.

2. Planting method: dig planting holes according to the plant spacing of 0.8m, straighten the root system of seedlings, put them into the holes, then fill half a pit with cooked soil, pour 2-3 pots of water into each pit, and then cover the cooked soil with ridges.

Fourth, post-planting management.

1. Film laying: After the seedlings are planted, the clods on the ridge surface will be broken and leveled, and the film will be laid immediately. The film width is 1- 1.2m, and a wooden stick should be inserted at the contact between the film and the seedlings, and the film should be covered from top to bottom to avoid damaging the seedlings. After the film is laid, the surrounding area should be covered tightly with soil.

2. Bagging: after the seedlings are planted, cover the seedlings with plastic bags or newspaper bags with a diameter of about 12 cm, and the bags are filled with semi-dry soil. After 7-9 days, when the buds turn green, remove the soil bags and clean up the soil on the ridge surface.

3. Irrigation: After the seedlings are planted, immediately irrigate the dried pond and the water will flow to the bottom of the ridge.

4. Temperature control: For the seedlings that are not bagged and buried in soil, in order to ensure the normal germination of buds and improve the survival rate of seedlings, after planting, film laying and irrigation, the temperature is gradually increased for three times. The method is to put down all the grass curtains, so that no light can be seen indoors, and close the vent, and control the temperature at10℃ for the first 5 days; In the second 5 days, draw a curtain every 3-5 curtains, and control the temperature at 65438 05℃; Draw a curtain every 1 curtain for the third 5 days, and control the temperature at 20℃; /kloc-After 0/5 days, when the buds turn green, take down all the curtains and control the temperature at about 25℃.

5. Go to the cabin. At night, when the continuous minimum temperature is 12℃, the film will be released, usually in the middle and late May.

Verb (abbreviation for verb) summer management

1. Leave buds: After the grapes are planted, leave the first strong bud for each plant to sprout new buds and grow forward. When the new shoots grow to 30-40 cm, they will be tied with scaffolding.

2. Bud wiping: Wipe off the buds on the trunk except the first bud in time.

3. Picking: Leave two leaves of summer buds on the new shoots for picking. When the main vine is stretched to 60cm, the main shoot is denucleating. The top two secondary auxiliary branches were selected for key cultivation, and the remaining auxiliary branches were treated with 1 leaf coring or bud smearing. When the remaining two auxiliary branches are 50cm long, the leaf coring treatment is repeated twice. By the end of August, all the auxiliary branches are cored to promote the maturity of the branches. When logging in winter, it is important to control the logging diameter above 0.6cm and try to keep the basic tree shape unchanged.

4. Cut the tendrils: cut the tendrils on the new shoots in time during the growing period.

5. Irrigation: The irrigation period and irrigation amount of grapes in solar greenhouse should be flexibly controlled according to soil, indoor microclimate and plant growth.

6. Loosening: After the grapes are planted, water is poured once, and the soil will be loosened if it is not sticky.

7. Topdressing: In the year of planting, during the third irrigation, dig a pit with a depth of 5 cm at the 20 cm of the plant and apply about 25 g of urea to the plant; During the fourth irrigation, about 50g of compound fertilizer was applied to the plant at a distance of 30cm and a hole depth of 5- 10cm.

8. Application of base fertilizer: apply base fertilizer once before defoliation from June, 5438 to 10 in autumn, dig a fertilization ditch with a width of 30cm and a depth of 50cm at the inter-row spacing, and pile raw soil and cooked soil separately. Padding 10 cm of wheat straw or corn straw on the bottom of the ditch, spreading 10 cm of cooked soil on it, fully mixing the cooked soil with fully decomposed farm manure (cattle and sheep manure), filling it with 30 cm, applying 1 kg of diamine phosphate on the surface of each ditch, and covering1on the cooked soil. Apply decomposed organic fertilizer 4m 3 per mu. The position of fertilization ditch rotates every year, and the amount of fertilization increases year by year.
