The underground stem of ginger is called rhizome, which is both a product organ and a reproductive organ. The formation process of rhizome is: after ginger germinates and emerges, it gradually grows into the main stem. With the growth of the main stem, the base of the main stem gradually expands, forming a small rhizome, usually called "ginger mother". The axillary buds on both sides of ginger can continue to sprout 2-4 Jiang Miao, that is, primary branches, and their bases gradually expand to form primary ginger blocks, which are called ginger.

Growth habit of ginger:
Ginger is mainly distributed in central and eastern China, southeast to southwest, Laifeng, Tongshan, Yangxin, Sun Yicheng, Xianning and Tongling. Changyi, Anqiu and other cities in Shandong Province are widely cultivated and are also common in tropical Asia. ?
Ginger likes warm and humid climate and is weak in cold and drought resistance. This plant can only grow during the frost-free period. The optimum growth temperature is 25-28℃, and when the temperature is lower than 20℃, the germination is slow. Plants will wither when they encounter frost, and frozen roots will completely lose their ability to germinate.
Ginger likes humid climate, but is afraid of humidity, direct sunlight and continuous cropping. Therefore, it is best to choose sloping land and slightly shady land for planting ginger. The upper layer is deep, loose, fertile sandy soil with good drainage, which is suitable for heavy soil.
