新镇痛药物资源角蒿(Incarvillea sinensis)的种子生物学及栽培技术研究

目的:研究角蒿驯化栽培生产技术。方法:进行野外调查,采集,弄清角蒿的生态习性和资源状况;进行种子生物学研究及田间栽培实验。结果:野生角蒿多见于干燥的草原地带,土壤以沙壤土为主,喜全光照、干燥气候;以种子进行繁殖,种子无休眠特性,千粒重约为0.4～0.5g;幼苗为子叶出土型;基生叶对生,茎生叶互生;栽培时对土壤要求不严格,喜肥。播种时需将种子与湿沙混合,浅播,播后加强水分管理,其它管理措施与二年生作物相同。结论:角蒿野生资源稀少,栽培技术较为简单,该技术有利于角蒿的规模化开发。

A studies of the seed biology and cultural technique of Incarvillea sinensis as a new analgesia medicine resource

Objective the technical study of domestication, cultivation, and produc-tion of Incarvillea sinensis. Methods clarifying the ecological habit and resources condition of Incarvillea sinensis by means of the field investigation and collection; the biological study of the seed; the field cultivated experiment. Results The wild Incarvillea sinensis occur normally in dry steppe region. The soil is mainly sandy loam. The plant likes total exposure and dry climate, and propagates by seeds. The seed has no dormant feature. The weight of a thousand seeds is about 0.4-0.5g. The cotyledons of seedling are epigeous. The basal leaves are opposite and stem leaves are alternative. The seeds are sowed shallowly in the soil with wet sand. The water management should be tightened. The other managements are the same with that of two year plant. The plants cultivated in normal soil with fertilizer are growing well. Conclusion The wild Incarvillea sinensis is rare. The cultural technology is simple, which is advantageous to the development of Incarvillea sinensis on a large scale.
