Grape (scientific name: grape? L) It is a woody vine of Vitaceae, with cylindrical branchlets, longitudinal edges, hairless or sparsely pilose leaves, dense or scattered panicles, well branched at the base, spherical or oval fruit, which blooms in April-May and bears fruit in August-September.

growing environment

The lowest temperature for grape growth is about 12℃- 15℃, the lowest ground temperature is about 10℃- 13℃, the optimum temperature for flowering is about 20℃, and the optimum temperature for fruit expansion is 20℃-30℃.

Such as large temperature difference between day and night, good coloring and high sugar content. After the grapes germinate in spring. If the temperature rises too fast, it will easily lead to the branches growing too fast, which is characterized by insufficient node length and poor fertilization at flowering stage. In case of cold spring, we should pay attention to applying more phosphate fertilizer and high-carbon organic matter and reducing nitrogen fertilizer as much as possible.
