Key points of High yield and High efficiency cultivation techniques of Pinellia ternata
Pinellia ternata is a perennial herb, which is used in medicine as tuber. Judging from the planting of our land for many years, the general benefit per mu is about 10,000 yuan. The main points of its high-yield and high-efficiency cultivation techniques are introduced as follows: first, in view of the growth habits of Pinellia ternata, which likes warmth, fertilizer, moisture, drought, waterlogging and high humidity, fertile sandy loam with higher topography and better irrigation and drainage conditions should be selected for planting.
