Is Yangcheng area in Jincheng, Shanxi suitable for growing grapes?

Effects of climate, soil quality and topography on grapes

First, the influence of climate.

1. The ideal temperature for grape growth is the annual average temperature 14 to 15 degrees Celsius. The average temperature in summer should not be lower than 19 degrees Celsius. The temperature in summer should not be too high, and the temperature in autumn should not be too low.

2. There needs to be rainfall in spring and summer, and the accumulated rainfall should be about 675 ml per year, but it is not advisable to have too much rain in summer and autumn.

3. Bad weather is unfavorable to the growth of vines, such as frost, strong wind, hail, rainstorm, etc.

Second, the impact of soil quality

1. The growth of grapevines needs well-drained soil. The soil should keep a certain humidity, but it should not contain too much water.

2. Warm soil, such as coarse sandy soil, sandy soil and poor soil, can keep a certain amount of heat and promote the maturity of vines. Cold soil, such as clay, will hinder the ripening of vines.

3. The rocky Burgundy soil can absorb the heat emitted by the sun; It can release heat at night, which is very good for vineyards with cold weather.

Third, the influence of topography.

1. Slope is not only conducive to the concentration of sunlight, but also better drainage, so it is more suitable for planting vines than flat land with fertile soil.

In the northern hemisphere, the hillside facing south can absorb more sunlight, so it is warmer. In the southern hemisphere, and vice versa. In hot areas, the hillside with cool climate is also suitable for planting vines.

3. Altitude will also affect the temperature. The higher the altitude, the colder the weather and the longer the grapes ripen.
