文章阐述了植物引种栽培4个过程，首先通过运用相似分析法则，判定物种的原产地区与引种地区的生态环境是否相似；其次运用类比推断法则在引种地区找出与计划引种在植物分类学上亲缘关系相近的参照物种，用以判断计划引种物种是否为引种地区的潜在物种；然后，对推定的潜在物种进行实际栽培试验；最后，通过驯化—适应过程，用以判断是否进行正式引种栽培推广。%The research for plant introduction and cultivation is an emphasis upon this course.Firstly,a law for analysis of similarity is applied to make sure that the ecological environment between both of the original region and the introduction region is similar.Secondly,another law for principle of analogism is applied to discover control species which is closely related with the introducing species based upon the plant taxonomy and also has a good performance of growth.Therefore,we can infer that the introducing species may be a potential species in the introducing region.Thirdly,a practical test of cultivation with the inferable potential species is achieved in the introducing region.Fourthly,after it goes through the whole course of domestication and adaptation and has good performance of growth,the test is successful,and the popularization of the introducing species should put into practice.
