1_ Fruit Characters
After many years of practice, per 667m2 yield 1500kg, the number of fixed panicles is 2000, the plant spacing is 3m, the number of fixed panicles is 9 /m, the panicle length is less than 20cm, the width is10 ~1cm, and the average weight is1cm.
2_ Planting density
Plant 55 plants per 667m2 with a row spacing of 3m×4m. The width of planting ditch is about 1m, and the depth depends on the soil quality and groundwater level, and it is suitable to be 30 ~ 80 cm. Fertilization must be applied when planting. The bottom of the ditch should be covered with a layer of straw, covered with soil, and 3000kg of organic fertilizer for livestock and poultry, phosphate fertilizer 100kg, one layer of fertilizer and one layer of soil, and the upper layer of 20cm should be made of original topsoil without fertilization.
3_ Water and fertilizer technology
Apply base fertilizer in autumn, from the end of September to 15d before defoliation. Every 667m2, 3000kg of commercial sheep manure, 20 ~ 40kg of Jin Lei calcium magnesium fertilizer, 30 ~ 40kg of granular slow-release silicon fertilizer and 5 ~ 10kg were used. Apply root-promoting fertilizer before germination (after bleeding point) and drip irrigation with seaweed extract 1kg+ Jin Lei 5kg. The fertilizer for promoting branches and strengthening branches should be applied at the 5-6 leaf stage, and the water-soluble fertilizer of 20-20-20 is 4kg in Jin Lei (it is not necessary if the trees are in good condition). Fertilizers for promoting flowers and keeping fruits were applied 7 ~ 10 days before flowering, and 5 kg of water-soluble fertilizers of 10-30-20+ 1 kg were used. The fruit-preserving fertilizer was applied 1 ~ 2 days after the fruit-preserving treatment, using 20-20-20 water-soluble fertilizer (weak trees were changed to 30- 10- 10 water-soluble fertilizer) 5kg+ Jin Lei 5kg+ calcium carbonate 1kg. The fruit swelling fertilizer was applied 7 ~ 10 days later than the last fertilization, using 30- 10- 10 water-soluble fertilizer 5kg+ Jin Lei 2.5kg+ calcium carbonate 1kg. However, 5 kg of 20-20-20 water-soluble fertilizer and 5 kg of Jin Lei were used before and after the fruit expansion period. Pay attention to calcium supplementation during the hard core period, and then apply it when the fruit stops growing. Use 20-20-20 water-soluble fertilizer 4kg+ calcium carbonate 2kg+ strength protection 1kg. In the early stage of fruit softening, fertilization should be applied when a single fruit has just softened, and 5 kg of water-soluble fertilizer 15- 10-30+5 kg of Jin Lei+calcium carbonate 1kg should be used. In the middle stage of fruit softening, the fruit is softened by 30%, 7 ~ 10d after the last fertilization, and the water-soluble fertilizer 15- 10-30 is used at a rate of 4kg+ 1kg. If you want to delay maturity, you can use 3 kg of 20-20-20 water-soluble fertilizer+1 kg of seaweed extract 7 days after the last fertilization, and use it again every 7 days. The fertilizer in the color-changing period was applied 7 ~ 10 days after the last fertilization, and 4 kg of 5- 10-40 water-soluble fertilizer+1 kg of imported phosphorus and potassium was used. 7 ~ 10 days after the last fertilization, 4 kg of 5- 10-40 water-soluble fertilizer+1 kg of calcium carbonate+1 kg of red paste was applied.
4_ Plastic trimming
T-shaped cultivation frame is adopted. For the first time, 7 ~ 8 leaves of new shoots were cored; In the germination stage, after the new buds germinate, leave 3-4 leaves above the tidbits for core picking, and start core picking when the last left leaf grows to the palm of your hand. Management of secondary branches: 3 ~ 5 days after the first coring, all the secondary branches under the flower are erased, and two secondary branches on the flower are kept. After three leaves grow, leave two leaves for each secondary branch, and then core. Pruning in winter, leaving 2 buds at the base of each fruiting mother branch and cutting off the extremely short top.
5_ regulation of flower and fruit
Three days before the flowering of Sunshine Rose Grape, 7 ~ 8 layers of spike tips were left, with about 17 ~ 18 small branches. The branches on the left and right sides of the inflorescence are horizontal, and the other spikelets are cut off, leaving 70 ~ 80 buds. On the 30th day after flowering, the new shoots with a length of more than 100cm leave two clusters of fruit ears, those with a length of 50 ~ 100 cm leave 1 cluster of fruit ears, and those with a length of less than 50cm leave no new shoots. After flowering 10d, the fruit is thinned, and 70 fruits are left per ear. Remove damaged and deformed fruit grains, as well as dense inner hall fruit grains and smaller fruit grains. Heading at 2 1d after flowering, leaving 2000 ears of fruit every 667m2 and heading for 2-3 times. Bagging time should be selected when the fruit diameter reaches 65438±0cm after physiological fruit dropping to prevent sunburn and gas burning. Seedless treatment was carried out on the third day after flowering, and spikelets were dipped in puning (1 bottle 100mL, water 90kg). After flowering 12 ~ 15d, dip spike puning for the second time.
6_ Pest control
30 days before germination, spray branches with 0.25 kg of graceful bud (cyanamide) and 6 kg of water until dripping. Seven days later, spray branches with 600 times of seaweed extract and 5000 times of Bihu liquid. During piling, the garden can be thoroughly cleaned with stone sulfur mixture, and the water consumption per 667m2 is 150kg. In the three-leaf stage, thiophanate-methyl 1500 times solution+imidacloprid 1500 times solution+800 times solution of fruits and vegetables+3000 times solution of organic zinc were used. At the 8 ~ 10 leaf stage (before and after coring), we used Baitai 800 times solution+thiamethoxam 1500 times solution+pyrimethanil 800 times solution+seaweed extract 800 times solution+organic boron 1500 times solution+organic calcium 1500 times solution. Use Huiyou 4000 times solution+Aarika 1500 times solution+Baitai 800 times solution+difenoconazole 1000 times solution+calcium boron essence 800 times solution+Jinguo 10-30-20 type 800 before flowering. Spray the whole plant, focusing on the ear, without dripping. After flowering (65,438+0,000 days after fruit preservation), quinolinone 65,438+0,500+pyrimethanil 800+organic boron 65,438+0,500+organic calcium 65,438+were used. In the young fruit expansion period (before and after fruit expansion), 65,438+0,500 times of Jinda+65,438+0,000 times of quinolones+65,438+0,500 times of pesticides+65,438+05-65,438+00-30 times of jinweiguo were used. In the hard core stage, amikacin 1500 times solution+quinolinone 1000 times solution+chlorantraniliprole 1500 times solution+organic calcium 1500 times solution+pigment treasure 800 times solution were used. In the early softening stage (medication before bagging), bagging combination (five combinations) 1500 times solution+Fruit and Vegetable King 800 times solution+15- 10-30 type 800 times solution was used. Spray the whole plant, focusing on the ear of the fruit, without dripping. In the later stage of softening, quinolinone 1000 times solution+tebuconazole (or fluorosilicone) 6000 times solution+fruit and vegetable king 600 times solution+organic potassium 600 times solution+calcium borate 600 times solution were used. Before picking,15 days, 600 times of fruit and vegetable king solution+600 times of organic potassium solution+600 times of calcium and boron essence solution were used.
7_ Fruit Harvest
When the skin of Sunshine Rose Grape is yellow-green (golden yellow when it is fully mature), which shows the inherent fragrance and unique flavor of the variety, it can be harvested. 10 can be picked from mid-late July to early June, and can be picked in the morning when the temperature drops and in the sunny afternoon. The picked grapes should be pruned by professionals, and each packing box should be sold in two strings, so as to keep the packing boxes tight and prevent the particles from falling during transportation.
