1992~1994年,通过对甘遂生活习性,生物学特性,种子处理,病虫害防治等调研和试验研究,肯定有性繁殖优于无性繁殖,有性秋播优于春播。发现了种籽后熟,植株夏眠等生物学特性。1994年底收获表明,有性3、4年生甘达,个大、色白、粉性足,产量达254。99~344,989/m2。栽培后植物鉴定无变异。有性栽培和野生甘遂成分的初步对比分析研究表明:成分相同,符合药典规定,能同等入药。总结出一套完整、切实可行的栽培技术,为保护中药资源及药农种药致富提供了科学依据。

[Abstract]
FroM1992 to1994,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 of1994,the yield of sexual reproduction of E. kansuigrown3 or4 years was254.90~344.98g/mz and the tubers are larger and whiter,with enoughgranular powder. The annualnet 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 thenatural one,which complied with the criteria of the Pharmacopoeia. A complete and feasible cultivation programme has been summed up,which provides a scientific basis for the protection of medicinal herbal resources and the benefit of medical herb cultivators.
