The Minimum Cold Resistance Temperature of Sunlight Rose Grapes
Today, the editor will introduce the related experience of planting flowers for the minimum cold resistance temperature of sunlight rose grapes. Let's follow the editor and have a look!
The Minimum Cold Resistance Temperature of Sunlight Rose Grapes
Sunlight rose grapes are cold-resistant, with a cold resistance temperature of -15 degrees Celsius. However, in the north where the temperature is -10 degrees Celsius, it is necessary to bury the sunlight rose grapes in soil for warmth. Moreover, it is recommended to water the grapes 10 days before burying them to prevent the roots from freezing. In areas north of the Great Wall, it is suggested to cultivate them in protected or greenhouse environments to help them warm up and maintain sweetness. However, in the southern regions, it is best to avoid planting sunlight rose grapes during the rainy season.
In recent years, sunlight rose grapes have been recognized by many farmers, and more and more farmers are planting them. Next, let's specifically introduce the minimum cold resistance temperature of sunlight rose grapes.
Are Sunlight Rose Grapes Cold-Resistant?
Sunlight rose grapes are cold-resistant. Moreover, they have a strong adaptability, being planted from the southern regions like Yunnan and Guangxi all the way to the northern areas.
Especially in areas north of the Great Wall, it is recommended to cultivate them in protected or greenhouse environments to help them warm up and maintain sweetness. However, in the southern regions, it is best to avoid planting sunlight rose grapes during the rainy season.
The Cold Resistance Temperature of Sunlight Rose Grapes
The cold resistance temperature of sunlight rose grapes is -15 degrees Celsius. However, in the north where the temperature is -10 degrees Celsius, it is necessary to bury the sunlight rose grapes in soil for warmth. Moreover, it is recommended to water the grapes 10 days before burying them to prevent the roots from freezing. The first burial should be carried out when the temperature is continuously 2 degrees Celsius for two days.
The most suitable growth temperature for sunlight rose grapes is between 20 to 30 degrees Celsius. To prevent frost damage to the fruit-set grape seedlings and avoid fruit drop and reduction in yield, it is best to keep the temperature above 20 degrees Celsius.
Key Points for Overwintering Sunlight Rose Grapes
In order to ensure that sunlight rose grapes overwinter better, a large amount of pruning is required. Moreover, if the humidity is high, pruning will immediately cause sap flow. Therefore, to avoid sap flow, pruning should be done when the air and soil temperatures are high, which will help the sunlight rose grapes overwinter better.
For outdoor sunlight rose grapes, in addition to burying in soil, there are few ways to ensure complete safety. The use of non-woven fabric and felt can ensure that the grapes survive normal winters. Facing strong cold air, burying in soil is still the safer option.
In winter, in addition to preventing frost, it is also necessary to prevent drought and prevent the dry cold north wind from drying out the branches. Winter irrigation before freezing is a common method; water should be applied generously at this time.
The above is a comprehensive introduction to the minimum cold resistance temperature of sunlight rose grapes, hoping to bring some knowledge about green plants to greenery enthusiasts.
