Sunshine Rose Cultivation Techniques and Management
Sunshine Rose grapes generally require cultivation under a shelter to avoid rain, especially in southern regions, where the high rainfall and humidity throughout the year can lead to rot diseases if not protected. In the north, Sunshine Rose grapes can be grown in the open air, but the quality and yield are not as good as those grown in greenhouses. It's best to adopt facility cultivation to increase the temperature of the growing environment in spring, making the grapes tastier.
The Sunshine Rose was originally bred by a Japanese agricultural research institution and showed excellent traits after being promoted and planted in Japan, which attracted the attention of Chinese industry professionals. Initially, when it was introduced to China, most of the fruit had small berries, a yellow-green appearance, and an unpleasant odor similar to body odor. After more than ten years of localization attempts, delicious and attractive Sunshine Rose grapes were finally successfully cultivated. Currently, China's planting area has reached 5 million mu, eliminating the need for imports, and it has become a common commodity.
Sunshine Rose Cultivation Techniques
1. Tree Management
After topping, the diameter of the leaves should exceed 27 cm for the best results. If the grape leaves become wrinkled, it may affect the fruit and yield. Keeping the plant with few small僵 fruit and larger berries is the main measure for tree management.
2. Proper Fertilization
Sunshine Rose is a variety that prefers fertilizer. It can be applied with nitrogen, phosphorus, and potassium. More fertilizer should be applied in the early stage, and after the fruit sets, a compound fertilizer of nitrogen, phosphorus, and potassium can be applied. In southern regions, germination stimulant fertilizer and magnesium sulfate can be applied.
3. Thickening of the Main Stem
Thickening the main stem is beneficial for the plant to bear fruit. It is possible to thin out every second plant after 1-2 years of fruiting, and then thin out every second plant again over the next two years to increase the fruiting rate of Sunshine Rose.
4. Vine and Leaf Management
Good digital management of vines and leaves can promote bud differentiation and ensure stable annual yield, allowing the base of the vines to accumulate nutrients, which is essential for the plant to form good flower buds.
Sunshine Rose Management Methods
1. Prevent Sunscald and Heat Stress
Sunscald is mainly caused by direct sunlight. In this case, we need to provide shade for the fruit clusters. When shading, it should not be too closed to maintain good ventilation. If ventilation and heat dissipation are poor, heat can accumulate, leading to various diseases and pests.
2. Slightly Control Watering and Fertilization
When the soil moisture of Sunshine Rose is too high, do not water and fertilize. Fertilization and watering should be done after 3 pm or in the evening, otherwise it can reduce the vitality of the roots.
3. Vine Management
The leaf-fruit ratio of Sunshine Rose should be above 1:6. In the later stage of growth, it is necessary to maintain enough leaves and control the growth of the shoot tips during the fruit expansion period to supply nutrients fully for secondary expansion.
4. Pesticide Application
Sunshine Rose should not be treated specifically with quinalphos to remove fruit powder. It is recommended to use Luanasen at a concentration of 2500 times or more, along with a soluble granule formulation. Others should not be added to avoid pesticide residue and harm.
