Where are the production areas of Ophiopogon japonicus distributed? An introduction to the latest situation

Ophiopogon japonicus, also known as lilyturf, ribbon grass, maidong, cundong and so on, is a perennial herbaceous plant of the Liliaceae family. Its production areas are mainly divided among Jiangsu, Anhui, Zhejiang, Fujian, Guangxi, Sichuan and other places. Representative products include Zhemaidong and Chuanmaidong. Let us take a look below at the production area distribution of Ophiopogon japonicus!

Production area distribution of Ophiopogon japonicus

1. Zhemaidong: Zhemaidong, also known as Hangmaidong, Jianmaidong and so on, is Ophiopogon japonicus produced in the Jianqiao area of Hangzhou, Zhejiang, and later broadly refers to that produced in Zhejiang. Its quality is the best, and it is a genuine medicinal material. Its main production areas are Yuyao, Hangzhou, Cixi, Xiaoshan and other places in Zhejiang.

2. Chuanmaidong: Chuanmaidong, also known as Chuandong, is mainly produced in the Mianyang area of Sichuan. The Ophiopogon japonicus produced on the Fujiang alluvial plain is considered the best, also called Fucheng maidong, and is sold throughout the country and exported.

Growth habits of Ophiopogon japonicus

Ophiopogon japonicus prefers a warm, humid and relatively shaded environment, is cold-resistant, and avoids strong light and high temperatures. When flowers appear in July, the underground tuberous roots begin to form. September to October is the peak period for root development, November is the tuberous root expansion period, and after temperatures rise at the end of February, tuberous root expansion accelerates.

Ophiopogon japonicus seeds have a certain dormant characteristic. A low temperature of about 5°C for 2 to 3 months can break dormancy and allow normal germination. The seed lifespan is 1 year, and in production, division propagation is usually used.
