Where is the main producing area of Chinese pepper?

The producing area of Zanthoxylum bungeanum starts from the south of northeast China, to the north slope of Wuling in the south, to the coastal zone of Jiangsu and Zhejiang in the southeast, and to the southeast of Xizang in the southwest; it is not produced in Taiwan, Hainan and Guangdong. Found in plains to higher mountains, in Qinghai, in slopes of 2500 meters above sea level, but also cultivated.

Zanthoxylum bungeanum is suitable for warm, humid and deep fertile loam and sandy loam, with strong sprouting, cold resistance, drought resistance, sunshine resistance, strong disease resistance and long hidden bud life, so it is resistant to strong pruning. Not resistant to waterlogging, short-term stagnant water can lead to death.

This variety is divided into two types, one kind of leaflet is thin papery, the color is obviously different after drying, the back of the leaf is grayish white, the fruiting pedicel is slender and prolonged; the other kind of leaflet is thickly papery, the leaf surface and fruiting pedicel are glabrous, the lateral veins are sunken in the leaf surface, the leaflets are nearly the same color on both sides, the reddish brown after drying, and the fruiting pedicel is thicker. The flowering period is from May to June and the fruiting period is from October to November.
