III. What are the growing techniques for Summer Black grape?
1. Site selection and land preparation: What soil is suitable for planting?
Summer Black grape is suitable for growing in an environment with loose soil, deep fertility, good drainage and irrigation, and sufficient water sources. So when choosing a site, try to choose loam with sufficient water sources for planting. After choosing the site, deep plow the soil, and apply 1500 kg of decomposed manure and 100 kg of calcium fertilizer per mu, then dig holes 0.8 m wide and 0.6 m deep at a spacing of 1.2 m between plants and 2.5 m between rows, in preparation for later planting.
2. Seedling selection: What kind of seedlings are good to choose?
Select some seedlings with well-developed root systems, undamaged exteriors, no diseases, and strong branches, then straighten out the roots and prepare to plant.
3. Transplanting: When is the best time to transplant?
(1) Transplanting time: late November to March of the following year.
(2) Transplanting method: Select thick, strong seedlings, then keep 2 to 3 buds per plant and transplant them into the dug holes. Finally, cover with soil, press firm, and water lightly.
4. Post-transplant management: How to manage?
(1) Building a trellis: When the grape grows to 30 to 50 cm, insert some stakes beside the seedlings and stretch several wires between the stakes to form a net.
(2) Young tree management: When the young tree grows 8 true leaves, apply nitrogen fertilizer once every half month, and then add phosphorus and potassium fertilizer in August to September. When the new shoot grows to about 55 cm, tie the vine to the wire with rope to help fix the branches.
(3) Flowering and fruiting stage management: When the new grape shoots grow more than two inflorescences, thin the flowers so that each new shoot only needs one inflorescence. At the same time, remove the surrounding dense branches and pest-diseased branches to improve the fruit-setting rate.
(4) Fruit expansion stage management: 15 days after the grape flowers fade, spray gibberellin solution once every half month to increase fruit yield. Of course, you can also spray some gibberellin solution when the grapes are as big as soybeans. At the same time, apply nitrogen fertilizer once, and apply potassium fertilizer once before the fruit ripens, to improve the fruit-setting rate.
(5) Shaping and pruning: After all the grape leaves have fallen, prune the branches, keeping only 3 buds per plant and cutting off all the rest, to promote a high yield the following year.
The above is a detailed introduction to the market price and growing techniques of Summer Black grape. I hope it is helpful to everyone.
