| 摘 要： | 通过收集云南省小桐子主要分布区23个县(市)的资源,分析小桐子的地理空间分布格局和种仁含油率与海拔、土壤类型、土层厚度及坡向等因素的关系。结果表明:云南小桐子在海拔400～1900 m均有分布,但主要集中在海拔800～1700 m;分布纬度21°57'—26°59'N、经度98°49'—103°7'E,在纬度24°13'—26°9'N、经度100°1'—102°13'E区域分布较集中。海拔1401～1600 m的小桐子含油率显著高于其他海拔;不同类型土壤的小桐子含油率有显著差异,其中耕作土的小桐子含油率显著高于其他土壤;而不同坡向、不同土层厚度对小桐子含油率的影响不显著。

| Abstract: | Based on the resources collected from the main distribution areas,23 counties or cities in Yunnan Province,this study analysed the geographic spatial distribution pattern of Jatropha curcas,and the relation ship between factors(such as altitude,soil type,soil thickness and slope direction) and the oil content rate of shelled seeds.The results showed that in Yunnan,Jatropha curcas distributed from 400 m a.s.l.to 1900 m a.s.l.,mainly in 800 ～ 1700 m a.s.l.,in an area of atitudes 21°57' ～ 26°59'N and longitudes 98°49' ～ 103°7'E,mainly in the area of atitudes 24°13' ～ 26°9' N and longitudes 100°1' ～ 102°13' E.The oil content rate from 1401 ～ 1600 m a.s.l.was significantly higher than that from other elevations.Types of soil remarkably influenced Jatropha curcas seed oil content rate,the highest oil content rate was got from farming land.The effects of different aspects,different soilleyer thickness on the oil content rate weren’t evident. |
