This study surveyed situations of volunteers of Northwest A&F University serving rural left-behind children,and found that there are problems including weak volunteer awareness,unstable organization members,imperfect organization construction,and lack of effect incentive mechanism. Finally,it came up four recommendations: strengthening " active service" ideological education,improving management system construction,establishing incentive mechanism,and setting up brand project,to provide feasible path for agricultural universities serving rural weak groups in a better way.展开更多
