What is the optimal temperature for grape growth?
Today, the editor will share some small experiences about the optimal temperature for grape growth in plant cultivation. Here is a comprehensive introduction.
What is the optimal temperature for grape growth?
Grape roots are most active at 7-10 degrees Celsius, and the average temperature should ideally be maintained at 10-12 degrees. The growth of new shoots and flower bud differentiation is best at 25-30 degrees, and berries mature at 28-32 degrees. When planting grapes, choose a sunny, high terrain with loose and well-ventilated soil. Master the row spacing and plant spacing during planting to enhance ventilation, and pay attention to the management of water and fertilizer.
Characteristics of grape growth
Grapes thrive in sunny conditions and are suitable for cultivation in areas with low precipitation and deep soil layers. They are relatively cold-resistant and prefer a certain amount of low temperature in winter. They grow better in fertile sandy loam soil with good drainage. The main grape-growing areas in China are主要集中在(X-J), Shaanxi, Yunnan, Henan, and other places.

Are grapes heat-resistant?
Grapes can tolerate high temperatures, but when the temperature rises to 35 degrees Celsius, grape growth stops, and when it exceeds 40 degrees, burns can easily occur.
What is the minimum cold tolerance for grapes?
Different grape varieties have significantly different cold resistance. European varieties generally have the lowest cold resistance, with roots freezing at -4 degrees Celsius, such as 'Rose Honey' and 'Queen of the Vineyard.' The hybrid between European and American varieties has slightly better cold resistance, with roots freezing at -6 to -8 degrees Celsius.
At what temperature can grapes be planted?
The best time for planting grapes is in February-March in spring or October-November in autumn, as the temperature is suitable and can effectively improve the survival rate of grapes.
The grape growth process
Grape growth depends on the season. In spring, when the temperature rises, around March, they start to germinate and the leaves become green. Grapes bloom in May and bear fruit by July, and they mature by mid-August.
Grape planting methods
When planting grapes, choose a sunny, high terrain with loose and well-ventilated soil. Master the row spacing and plant spacing during planting to enhance ventilation. Pay attention to the management of water and fertilizer, avoid excessive watering to prevent diseases in the vineyard, and increase the proportion of phosphorus and potassium fertilizers.
The above is a detailed explanation about the optimal temperature for grape growth, for everyone's reference and suggestions!
