Suitable Places for Grape Cultivation
Grapes have a strong adaptability and can be planted in both the north and south regions. Currently, the southern regions of our country, such as Fujian, Guangdong, Zhejiang, and Yunnan, are where tree grapes are planted extensively, with Anhui, Shandong, and Zhangjiakou being the most well-known for grape cultivation.
Regions for Grape Cultivation
Grapes are mainly distributed between 20-52 degrees north latitude and 30-45 degrees south latitude. In our country, grapes are mainly distributed between 23-52 degrees north latitude, which means both the north and south of our country cultivate grapes.
The northern central part of Northeast China, including Jilin and Heilongjiang provinces, the northwestern part including Xinjiang, Gansu, Qinghai, etc., the Loess Plateau including Shanxi and Shaanxi provinces, the Bohai Bay region including Shenyang, Anshan, Yingkou in Liaoning province, and the southern region including Anhui, Jiangsu, Zhejiang, Shanghai, etc., are the main grape cultivation areas, with Xinjiang, Zhangjiakou, and Anhui being the most famous production areas.
Conditions for Grape Cultivation
Grapes are not cold-resistant and have strict temperature requirements. The growth temperature must not be below 12 degrees, or growth will cease. During flowering, a temperature of about 20 degrees is conducive to blooming. When the fruit is expanding, a temperature of 20-30 degrees is required. Moreover, a larger temperature difference between day and night is more beneficial for grape coloring and sugar accumulation.
Key Points for Grape Cultivation and Management
1. Environment
Grapes are warm-loving plants, and the optimal growth temperature is above 12 degrees. Therefore, the grape variety should be chosen according to the local environment. The soil should be loose, breathable, directly exposed to sunlight, and well-drained, which are the basic conditions for planting grapes.
2. Fertilization
The water and fertilizer requirements for grapes during growth are different and should be adjusted according to the growth of the grapes. After planting, apply nitrogen fertilizer and then water sufficiently to allow the roots to grow better in the soil.
3. Water Management
It is crucial to supplement water during the germination, flowering, and fruit fall stages of grapes. These three stages are key times for watering. The amount of water used should be determined by local precipitation conditions, and a large amount of water should be supplemented before the grapes are taken off the trellis to ensure they have enough water to survive the winter.
The above sharing of grape cultivation conditions, regions for grape cultivation, and specific introduction of key points for grape cultivation and management aims to provide netizens with some knowledge.
