How to plant Sunlight Rose grapes
This article focuses on knowledge about how to plant Sunlight Rose grapes and the cultivation techniques of Sunlight Rose grapes, including the grass and flower aspects. Next, the editor will introduce.
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 cultivation difficulty of such expensive Sunlight Rose is also greater than that of other common varieties. Today, Xue Nong Jun will introduce the cultivation techniques of Sunlight Rose grapes to everyone.
Limited root cultivation
So-called limited root cultivation refers to the restriction of the growth range of grape roots through root restrictors. Grapes have fleshy roots and their growth requires a certain amount of soil oxygen (specifically, oxygen content greater than 9%). Therefore, limited root cultivation can adjust the growth of grapes by controlling the soil. High-quality Sunlight Rose can also adopt limited root 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 a very strong market demand, so when choosing a planting area, it is best to choose a place with convenient transportation, fertile soil, and no waterlogging. The construction of rain shelters for Sunlight Rose differs from other varieties. When the temperature in the shed exceeds 32 degrees Celsius, Sunlight Rose will enter a growth停滞 period and is prone to sunburn and air burn, so the rain shelter must be ventilated and breathable.
Selection of good rootstocks and strong seedlings
Common good rootstocks for Sunlight Rose include Beida, 5BB, Xiahei, and SO4. Beida has the advantage of cold and frost resistance, grows well in neutral soil, has a rich aroma, and matures early, but it is prone to僵 seedlings in acidic soil and has poor resistance to root nematodes; 5BB has strong resistance to diseases and pests but matures later than Beida; Xiahei has strong growth in the seedling stage and stable flowering, but it is difficult to manage the flowering of the production tree; SO4 has good root growth but is difficult to graft, and the grafting joint is prone to longitudinal cracking, which can cause diseases and pests.
Sunlight Rose seedlings are best purchased from正规 institutions and units to avoid buying toxic seedlings. If virus-free seedlings are not available, you can choose to graft with superior scions.
Choice of frame type
Sunlight Rose is very sensitive to light and can easily develop a '阴阳脸' if not careful, so special attention must be paid when choosing the frame type. The large flat shed is the best frame type for Sunlight Rose, while traditional single篱架 and V-type frames are not suitable.
Sunlight Rose flowering technology
Through drought stress, promoting and breaking dormancy to ensure uniform germination;
When the branches are more than five centimeters long, remove the buds and fix the branches during the 3-leaf to 4-leaf stage;
Through water and fertilizer management and timely topping to promote the natural separation of inflorescences.
3-7 days before flowering, count 11 to 15 small branches from the end of the inflorescence upwards.
Seedless treatment
Preservation work: Strengthen water and fertilizer management before preservation, spray 920 after painting to prevent the fruit stalk from becoming thick and hard, and use chlorpyridine and streptomycin to preserve the fruit;
Remove single layer: Start removing the single layer 4-6 days after preservation and thin the fruit.
Management during rapid expansion period
12-15 days after preservation, the expansion treatment is carried out:
1. Strengthen water and fertilizer management;
2. Use regulators reasonably, such as chlorpyridine and 920;
3. Fruit cluster shaping.
Issue of sunburn and air burn
Prevention of sunburn:
1. Use shading nets;
2. Leave more leaves on the auxiliary branches of the fruit clusters;
* Japanese sunburn prevention technology: Leave auxiliary branches, and use colored bags.
Prevention of air burn:
1. Use drip irrigation;
2. Cover the ground with shading nets.
Management during the hard core period
To ensure the high quality of Sunlight Rose, do the following:
Do not use powdered medicines, focus on preventing grey mold, pay attention to controlling scale insects, pay attention to controlling thrips, and pay attention to the concentration and pressure of the medicine.
Fruit rust issue
Solving the fruit rust issue has the following three methods:
1. Strengthen water and fertilizer management to enhance tree vigor;
2. Choose a good regulator during the expansion process;
3. Control the concentration and pressure of the medicine when preserving the fruit.
Issue of sugar and aroma development
1. Improve the soil, fertilize in a timely manner, and ensure the nutritional needs of Sunlight Rose;
2. Control water and expenses 20 days before maturity;
3. Remove the shading nets near maturity to enhance light transmission;
4. It is advantageous to plant in areas with long daylight hours and large temperature differences between day and night.
