How to plant Sunlight Rose grapesA topic related to the cultivation of Sunlight Rose grapes and the technical points of growing Sunlight Rose grapes, the specific content is as follows:Sunlight Rose grapes, as the third-generation main cultivated variety, have shown a good development trend in recent years across the country. A fruit professional cooperative in Ningbo introduced Sunlight Rose grapes in November 2014. After scientific verification, this variety has the characteristics of stable and high yield, large berries, disease resistance, storage resistance, crisp and juicy fruit flesh, fragrant taste, high sugar content, soluble solids content of over 18%, excellent fresh food quality, no cracking, no shedding, and good comprehensive traits. In recent years, the cultivation of Sunlight Rose grapes has moved from traditional empirical management to standardized management mode, significantly improving the quality of fruit for market, and the influence of the "Qiao Mu Zi" brand has greatly increased, with the highest output benefit reaching 72,000 yuan per 667 square meters.1 Fruit characteristicsAfter years of practice, the yield per 667 square meters is 1500 kg, with 2000 clusters per plant, a plant spacing of 3 meters, 9 clusters per meter, a berry length not exceeding 20 cm, a width of 10-11 cm, maintaining an average weight of 1000 g, and 70 berries per cluster, with an average berry weight of 15 g.2 Planting densityPlant 55 vines per 667 square meters, with a spacing of 3 meters between rows and 4 meters between plants. The planting trench should be about 1 meter wide, and the depth should be determined by the soil texture and groundwater level, preferably between 30-80 cm. It is necessary to apply fertilizer during planting, with a layer of straw laid at the bottom of the trench, covered with soil, and then applying 3000 kg of livestock organic fertilizer and 100 kg of phosphate fertilizer, alternating layers of fertilizer and soil, with the top 20 cm using the original surface soil without fertilizer.3 Irrigation and fertilization techniquesApply base fertilizer in autumn, from the end of September to 15 days before defoliation. Use 3000 kg of commercial sheep manure per 667 square meters, as well as 20-40 kg of Jinlei calcium-magnesium fertilizer, 30-40 kg of compound fertilizer, and 5-10 kg of slow-release silicon fertilizer. Apply root-promoting fertilizer before germination (after wound flow), using 1 kg of seaweed extract and 5 kg of Jinlei for drip irrigation. Apply fertilizer to promote shoot growth during the 5-6 leaf stage, using 4 kg of 20-20-20 water-soluble fertilizer and 4 kg of Jinlei (not used for plants with good growth). Apply flower and fruit preservation fertilizer 7-10 days before flowering, using 5 kg of 10-30-20 water-soluble fertilizer and 1 kg of Jinhu. Apply fruit preservation fertilizer 1-2 days after fruit preservation treatment, using 5 kg of 20-20-20 water-soluble fertilizer (changed to 30-10-10 water-soluble fertilizer for weak plants) and 5 kg of Jinlei and 1 kg of Meical. Apply fruit expansion fertilizer 7-10 days after the last fertilizer application, using 5 kg of 30-10-10 water-soluble fertilizer, 2.5 kg of Jinlei, and 1 kg of Meical. Apply 5 kg of 20-20-20 water-soluble fertilizer and 5 kg of Jinlei before and after the fruit expansion period. Pay attention to calcium supplementation during the hard core stage, applying 4 kg of 20-20-20 water-soluble fertilizer, 2 kg of Meical, and 1 kg of Jinhu when fruit growth stops. Apply fertilizer at the initial stage of fruit softening, using 5 kg of 15-10-30 water-soluble fertilizer, 5 kg of Jinlei, and 1 kg of Meical. Apply fertilizer at the middle stage of fruit softening, 7-10 days after the last fertilizer application, using 4 kg of 15-10-30 water-soluble fertilizer and 1 kg of Jinhu. If you want to delay maturity, apply 3 kg of 20-20-20 water-soluble fertilizer and 1 kg of seaweed extract 7 days after the last fertilizer application, and repeat after another 7 days. Apply color change fertilizer 7-10 days after the last fertilizer application, using 4 kg of 5-10-40 water-soluble fertilizer, 1 kg of Jinhu, and 2 kg of imported potassium-phosphorus fertilizer. To increase sweetness and fragrance, apply 4 kg of 5-10-40 water-soluble fertilizer, 1 kg of Meical, and 1 kg of Hongshuang 7-10 days after the last fertilizer application.4 Pruning and shapingUse a high-width-vertical T-type cultivation trellis. The first pruning of new shoots is at 7-8 leaves; after germination, leave 3-4 leaves above the inflorescence for pruning, and start pruning when the last remaining leaf grows to the size of a palm. Management of lateral branches: 3-5 days after the first pruning, remove all lateral branches below the inflorescence, retain 2 lateral branches above the inflorescence, and prune each lateral branch after 2 leaves grow. For winter pruning, leave 2 buds at the base of each fruiting branch and perform a very short pruning.5 Flower and fruit regulationRetain the top 7-8 layers of the inflorescence, about 17-18 small branches, with horizontal left and right pedicels, cut off the rest of the small inflorescences, and retain 70-80 flower buds before the Sunlight Rose grapes bloom. 30 days after full bloom, retain 2 clusters of fruit on new shoots longer than 100 cm and 1 cluster on new shoots 50-100 cm long, and none on new shoots less than 50 cm long. Thinning fruit 10 days after flowering, leaving 70 berries per cluster. Remove damaged and deformed berries, as well as dense inner berries and smaller berries. Set the clusters 21 days after flowering, leaving 2000 clusters per 667 square meters, divided into 2-3 times. Bagging time is chosen after physiological fruit drop, when the berry diameter reaches 1 cm, to prevent sunburn and air burn. Perform seedless treatment 3 days after flowering, using Funing (1 bottle of 100 mL, diluted in 90 kg of water) to dip the inflorescence; 12-15 days after flowering, use Funing to dip the inflorescence for the second time.6 Pest and disease controlApply Youmei芽 (单一氨) 0.25 kg diluted in 6 kg of water 30 days before germination, spray the branches until dripping. After 7 days, use a seaweed extract solution 600 times and a Bihu solution 5000 times to spray the branches. During the downy stage, use lime sulfur solution to thoroughly clean the garden, using 150 kg of water per 667 square meters. During the three-leaf stage, use a solution of 1500 times甲基硫菌灵, 1500 times Pyridaben, 800 times Shu Guo Wang, and 3000 times Organic Zinc. During the 8-10 leaf stage (before and after topping), use a solution of 800 times Baitai, 1500 times Thiamethoxam, 800 times Pyrimethanil (or Pyrimorph), 800 times seaweed extract, 1500 times Organic Boron, and 1500 times Organic Calcium. 1-2 days before flowering (or when flowers are visible), use a solution of 4000 times Huiyou, 1500 times Alitac, 800 times Baitai, 1000 times Ben醚甲环唑, 800 times Calcium Boron, and 800 times Jinwei Guo 10-30-20. Spray the whole plant, focusing on the fruit clusters, without dripping. After flowering (1-2 days after fruit preservation), use a solution of 1000 times Quinoline, 1500 times Shachong Qing, 800 times Pyrimethanil, 1500 times Organic Boron, 1500 times Organic Calcium, 8000 times Bihu, and 800 times Yishou. During the fruit expansion period (before and after fruit expansion), use a solution of 1500 times Jianda, 1000 times Quinoline, 1500 times Shachong Qing, 800 times Jinwei Guo 15-10-30, 800 times Shu Guo Wang, 800 times Green Quartz, and 1000 times Anti adversity. During the hard core stage, use a solution of 1500 times Amimiao Shou, 1000 times Quinoline, 1500 times Chlorantraniliprole, 1500 times Organic Calcium, and 800 times Se Shai Bao. During the early softening stage (before bagging), use a combination of 1500 times bagging solution, 800 times Shu Guo Wang, and 800 times Jinwei Guo 15-10-30. Spray the whole plant, focusing on the fruit clusters, without dripping. During the late softening stage, use a solution of 1000 times Quinoline, 6000 times Tebuconazole (or Flusilazole), 600 times Shu Guo Wang, 600 times Organic Potassium, and 600 times Calcium Boron. 15 days before harvesting, use a solution of 600 times Shu Guo Wang, 600 times Organic Potassium, and 600 times Calcium Boron.7 Fruit harvestingWhen the skin of Sunlight Rose grapes is yellow-green (golden yellow when fully ripe), showing the inherent aroma and unique flavor of the variety, harvesting can begin, starting from mid-to-late July and continuing until early October. Choose a sunny morning and afternoon when the temperature drops for harvesting. After harvesting, the grapes should be trimmed by professional staff, graded and packaged in pairs per box, keeping the box tight and preventing loosening to avoid berry shedding during transportation.The above sharing on how to plant Sunlight Rose grapes and the technical points of cultivating Sunlight Rose grapes is hoped to be of help to you.
