Teach you the experience of cultivating ruby seedless grapes in protected areas.

Ruby seedless grape has high seed setting rate, uniform fruit grain, easy coloring, hard and crisp pulp, good flavor, early ripening and high yield, and strong adaptability. In 2000, we carried out continuous cultivation experiments in the solar greenhouse. On May 5th, the fruit matured 62 days earlier than that in the open field, the average plant yield was 4.5kg, the fruit yield per mu was 3000 kg, in 2002, the average plant yield was 4.8kg, the yield per mu reached 3500 kg, the economic benefit was obvious and the planting tube was easy.

The planting test site is located in the vineyard of Huiguokou Village in our district. The local frost-free period is 232 days, the annual rainfall is 650mm, the annual average temperature is 13.1℃, the terrain is flat, the soil is slightly alkaline, and the soil layer is deep and fertile. The garden was directly established with cutting seedlings in the spring of 2000, and the row spacing was 1 m × 1 m. Greenhouse structure greenhouse east-west direction, 50 meters long, 7.5 meters wide, 3.3 meters high on the ridge, 1 meter high on the front foot, 50 cm wide cold proof ditch at the front bottom corner, covered with straw or wheat straw. The east-west wall and the back wall are 50 cm hollow walls with perlite inside. There is a row of cement columns in the shed, which are 2.4 meters high. The upper bearing iron arch frame is covered with green non-dripping film, and there are thermal insulation curtains. The shed is equipped with simple flue coal furnace heating equipment. Third, cultivation techniques 1, planting and fertilizer and water management. Dig 30-40 cm planting hole before planting, apply 5000 kg organic fertilizer, 50 kg diammonium phosphate and 10 kg potassium sulfate per mu, mix with soil and fill in planting hole, then plant seedlings, and after planting, pour enough water to cover with film to preserve soil moisture. 50 grams of compound fertilizer was applied to plants before sprouting to flowering, 100g compound fertilizer was applied when the new shoot was 40 cm long, paclobutrazol was sprayed when it was 1 meter high, fertilizer water was stopped in mid-July, 0.3% potassium dihydrogen phosphate was sprayed after fruit setting to berry coloring, and 5000 kg of organic rotten chicken manure was applied after fruit picking. Sufficient water was filled in the first ten days of October, and the greenhouse was heated up and budding water was irrigated in the last ten days of November. 2. Shaping and pruning. After planting, the seedlings were pruned with Dulong stem type, each plant had one main vine, on which 4-6 fruiting branches were left, and no more fruiting branches were left. When it grows to 30 cm, set up and tie it up, and remove the accessory tip in the leaf armpit. Spray paclobutrazol on the main vine when the new shoot is 1 meter long, pick the heart when it reaches 2.5 meters, leave 2-3 secondary shoots at the top, and leave 2-3 leaves on each shoot in time. Leave a short cut of 60-80 cm before withholding the shed. After heating up, 5 new shoots were retained for each plant, and the rest were erased. When the new shoot grows to 20 cm, twist the tip and control the growth. 10-15 days later, when the post-hair tip grows to 20 cm, do coring treatment. When growing to 30-40 cm, use a rope to pull the new shoots with strong growth potential to fewer parts of the branches, so that the fruit branches are evenly distributed. Only 1-2 top shoots are left for the secondary shoots to be sent out, with 2-4 leaves per shoot. 3. Temperature and humidity control. Buckle the film from October 19 to 20, cover the grass cloak during the day to make the room invisible, open the tuyere for ventilation at night, and lower the temperature to the outdoor temperature for 30 days. Use lime nitrogen solution to wipe the mother branch so that it can break dormancy ahead of time. In the middle and last ten days of November, the temperature increased during the day, 18 ℃ at night from germination to flowering, 25-28 ℃ during the day, 15-18 ℃ at night, and no more than 30 ℃ during the day. The suitable temperature was 25-28 ℃, the night temperature was 20 ℃ during the young fruit expansion period, and then controlled at 18-20 ℃, 25-28 ℃ in the daytime, 25-28 ℃ in the daytime and 16-18 ℃ at night. Always pay attention to the temperature in the shed, turn on the heating equipment when it is too low, and keep the indoor temperature in the shed. The humidity can be higher in the budding stage, the relative humidity is 85-90%, the pre-flowering period is 60-70%, the flowering period is 60%, the fruit expansion stage is 50-60%, and the coloring period is 60-70%. It is necessary to uncover the grass early and cover the grass at night, increase the lighting time, fill the light with lights on cloudy and snowy days, and hang a reflective screen indoors. Remove dust and sundries from the greenhouse film at any time to increase light. When the carbon dioxide content decreases, the solid carbon dioxide fertilizer is applied. 4. Flower and fruit management. The weak branch does not stay, the strong branch leaves an ear, removes the accessory ear, pinches off the ear head, leaves 5 ears per plant, and removes small and dense grains. Spray 0.3% potassium dihydrogen phosphate when the berries are colored. 5. Disease and pest control. Spraying Baume 5-degree stone sulfur mixture before buckling shed, the early stage of new shoot growth, when the annual temperature is the lowest, it is easy to suffer from gray mold and downy mildew, so it is necessary to adopt ecological temperature management and regulate well according to the requirements of temperature and humidity in each stage. The medicament prevention and cure uses the smoke method and the dust wheel to change the medicine once a week. To pay attention to the control of whitefly, 25% EC of cyhalothrin can be sprayed. During fruit growth, it is necessary to prevent downy mildew and powdery mildew, which is a disease easy to occur in the greenhouse. Chlorothalonil fumigant and 16% anti-creamy powder can be used once every 7-10 days. You can also use 46% triethyl aluminum phosphate plus 15% triethyl aluminum phosphate 2000 times. Spray 200 times the Bordeaux solution after fruit picking, once every half a month, to protect the leaves.
