Is the climate in Bijie, Guizhou suitable for planting camellia oleifera?

Camellia oleifera can be planted in Bijie, Guizhou, but it needs to be selected reasonably according to the local climate and actual situation. Because the climate in Guizhou is characterized by poor lighting conditions, rainy days and high relative humidity. The annual sunshine hours in most areas are between 1.200 ~ 1.600 hours. The regional distribution is characterized by more in the west and less in the east, that is, the sunshine hours in the west of the province are about 1.600 hours, and those in the middle and east of the province are 1.200 hours. The sunshine hours in the whole year are less 1/3 or more than those in the eastern part of China at the same latitude, and it is the area with the most sunshine in China. Because it is located in the low-latitude mountainous area, the terrain height difference is great, the weather and climate characteristics in the vertical direction are quite different, and the three-dimensional climate is obvious. Therefore, it is known as "one mountain with four seasons, and ten miles of different days".

Growth habit of Camellia oleifera: Camellia oleifera likes warmth and is afraid of cold. The annual average temperature 16~ 18℃ and the flowering average temperature 12~ 13℃ are required. Sudden low temperature or late frost will cause falling flowers and fruits. Therefore, sufficient sunshine is required, otherwise only branches and leaves will grow, resulting in less results and low oil content. Sufficient moisture is needed, and the annual precipitation is generally above 1000 mm, but continuous rainfall at flowering stage will affect pollination. Suitable for planting in places with gentle slope and weak erosion. Camellia oleifera has low requirements on soil, and is generally suitable for acidic soil with deep soil layer, not suitable for places with many stones and hard soil.

Distribution: Camellia oleifera is one of the four major woody oil plants in the world. It mainly grows in the mountains and hills of subtropical areas in southern China, and is a unique natural high-grade oil plant in China. Mainly concentrated in Hunan, Jiangxi, Fujian, Zhejiang, Hubei, Anhui, Guangxi, Guizhou, Guangdong, Sichuan and other provinces.
