The Evaluation and Utilization of Wild Fruit Tree Resource of Subtropical Area in Guizhou Province

贵州亚热带地区野生果树资源十分丰富，现已收集到18科37属94种。根据植物学特性：有常绿乔木、常绿灌术或水乔木、常绿藤本和常绿草本，落叶乔木、落计灌木或小乔木和落叶木质藤本7类；果实为核果、浆果、仁果和瓠果。垂直分布于海拔150～1000m的常绿阔叶林或灌丛中。本文亦对该区野生果树资源蕴藏量，开发利用前景进行了综合评价．并指出引种栽培中土壤、水分、光照等因子是成功的关键。

The wild fruit tree resource of subtropical area in Guizhou province is distributed over the valleys of eightrivers and their joins,which are Nanpang river,Beipang river,Hongshui river,Wujian river,Chishui river,Wuyangriver.

By botany characteritic .wild fruit trees are divided into five kinds, such as evergreen arbor, small shrub,lana .de foliate arbor, small arbor and shrub. The fruits are divided into drupe,beny,collective fruit,aggregate fruit and pome. The reserves and developmental prospect of wild fruit resources of thisarea were synthetically evaluated in the article and it showed that environmental factors such as soil,water and lightwere tbe key to successful intruducing and cultivating wild fruit trees.
