[Abstract]
Experimental cultivation of Ephedra sinica Stapf on saline-alkaline soil was attempted to relieve the ever decreasing supply of this natural herbal drug. The ground was turned over and washed for several years until the salt content decreased from 2% to ≤ 1.2%. Furrows with a depth of 1~2 cm were ploughed and diammonium hydrogen phosphate fertilizer applied. It was covered with a layer of 0.5~1 cm sand after sowing with repeated watering. Results showed that E.sinica can grow better on a soil layer of 0-30 cm with ≤ 1.2% salt content, but less satisfactory when the salt content exceed 1.6%. It could be concluded that E.sinica may be cultivated successfully on saline-alkaline soil with medium salt content.
