How to plant Sunlight Rose grapes
Here is an introduction to how to plant Sunlight Rose grapes and the key points of cultivation techniques for green plants and flowers. Please feel free to correct any mistakes!
Sunlight Rose, one of the most popular grape varieties in recent years, is favored by the market and consumers for its rich aroma and high sweetness. Currently, the market price of high-quality Sunlight Rose can reach 100 yuan per jin, which seems extremely high. However, the difficulty of cultivating such expensive Sunlight Rose is also greater than that of other common varieties. Today, I will introduce the cultivation techniques for Sunlight Rose grapes.
Root restriction cultivation
Root restriction cultivation refers to limiting the growth range of grape roots through root restrictors. Grapes have fleshy roots and require a certain amount of oxygen in the soil (specifically, more than 9% oxygen content). Therefore, root restriction cultivation can regulate grape growth by controlling the soil. High-quality Sunlight Rose can also adopt root restriction cultivation, but it has its drawbacks and should be chosen based on actual planting conditions and management level.
Rain shelter construction
Sunlight Rose is a variety with strong market appeal, so it's best to choose areas with convenient transportation, fertile soil, and no waterlogging for planting. The construction of rain shelters for Sunlight Rose differs from other varieties. When the temperature inside the shed exceeds 32 degrees Celsius, Sunlight Rose will enter a growth停滞期 and is highly prone to sunburn and gas burn, so the rain shelter must be ventilated and breathable.
Selection of good rootstock and strong seedlings
Common good rootstocks for Sunlight Rose include Betta, 5BB, Xiahēi, and SO4. Betta has the advantage of cold resistance and good growth in neutral soil, with rich aroma and early maturity. However, Betta is prone to stunted growth in acidic soil and has poor resistance to root-knot nematodes. 5BB has strong resistance to diseases and pests but matures later than Betta. Xiahēi has the advantage of strong growth in young seedlings and stable flowering, but it is difficult to manage the flowering of production trees. SO4 has good root growth but is difficult to graft, with easily cracking grafting joints, which can lead to diseases and pests.
Sunlight Rose seedlings are best purchased from正规 institutions and units to avoid buying toxic seedlings. If virus-free seedlings cannot be obtained, you can choose good-quality scion grafts.
Selection of trellis type
Sunlight Rose is very sensitive to light, and it's easy to get a 'split personality' if not careful. Therefore, it's essential to pay attention when choosing the trellis type.
The large flat trellis is the best type for Sunlight Rose, while traditional single篱架 and V-type trellises are not suitable.
Sunlight Rose flowering technology
Through drought stress, promoting and breaking dormancy to ensure uniform germination;
When the branches are more than 5 cm long, remove the buds and fix the branches during the 3 to 4 leaf stage;
Through water and fertilizer management and timely pinching to promote natural separation of inflorescences;
3-7 days before flowering, count from the tip of the inflorescence and keep 11 to 15 small branches.
No-core treatment
Fruit protection work: Strengthen water and fertilizer management before fruit protection, spray 920 after fruit setting to prevent the fruit stem from becoming thick and hard, and use chlorpyridine and streptomycin for fruit protection;
Single-layer thinning: Start thinning 4-6 days after fruit protection.
Management during rapid expansion stage
12-15 days after fruit protection, conduct expansion treatment:
1. Strengthen water and fertilizer management;
2. Use regulators such as chlorpyridine and 920 appropriately;
3. Shape the fruit cluster.
Sunburn and gas burn issues
Prevention of sunburn:
1. Use sunshade nets;
2. Leave more leaves on the sub-branches above the fruit cluster;
* Japanese sunburn prevention technology: Leave sub-branches and use colored bags;
Prevention of gas burn:
1. Use drip irrigation;
2. Cover the ground with sunshade nets.
Hard core stage management
To ensure the high quality of Sunlight Rose, the following should be done:
Do not use powder-type pesticides, focus on preventing gray mold, control scale insects, control thrips, and pay attention to the concentration and pressure of the medication.
Fruit rust issue
To solve the fruit rust issue, there are three methods:
1. Strengthen water and fertilizer management to enhance tree vigor;
2. Choose a good regulator during expansion treatment;
3. Pay attention to the concentration and pressure of the medication when protecting the fruit.
Issue of sweetness and aroma
1. Improve the soil, fertilize in a timely manner, and ensure the nutritional needs of Sunlight Rose;
2. Control water and fertilizer 20 days before maturity;
3. Remove the sunshade nets near maturity to enhance light transmission;
4. Regions with long daylight hours and large temperature differences between day and night have advantages for planting.
The above introduces how to plant Sunlight Rose grapes and the key points of cultivation techniques. I hope you will like it!
