Abstract:
From 1992 to 1994,investigations and experiments of the botanical and biological habit,seed treatment,and control of diseases and pests of Euphorbia kansui were conducted in Yuncheng. Results showed that sexual reproduction is better than asexual,and sowing in autumn is better in spring. Biological characteristics such as afterripening of the seed and summer dormancy of the plant are also revealed. In the end of 1994,the yield of sexual reproduction of E. kansui grown 3 or 4 years was 254. 90~344. 98g/m2 and the tubers are larger and whiter,with enough granular powder. The annual net income is 50~65 Yuan/m2. No identifiable variation in the cultivated plant was observed,and its chemical composition proved to be the same as that of the natural one,which complied with the criteria of the Pharmacopoeia. A complete and feasible cultivation programmehas been summed up,which provides a scientific basis for the protection of medicinal herbal resources and the benefit of medical herb cultivators
