The development of Internet technology has brought convenience to the development of education and teaching,and has also changed the traditional methods and means of education and teaching. The construction of an integrated network teaching platform based on Internet technology brings new opportunities for the development of higher education. Taking the construction of the integrated network teaching platform of northwest A&f university as an example,the current situation and existing problems in the construction of the integrated network teaching platform of the northwest A&f university are explained. By proposing the promotion strategies for the application of the integrated network teaching platform,the construction of the integrated network teaching platform is improved,thereby facilitating the online and offline mixed teaching and further promoting the improvement of teaching level and teaching effect.

Due to the negative influence of family's cultural and education level,economic development,and rural traditional culture,rural college students have such abnormal psychology as inferiority complex in learning and job selection,high psychological pressure,sensitive interpersonal relationship,high emotion fluctuation,confusion in love and sex,and high unknown risks. Therefore,through strengthening the effectiveness of abnormal psychological prevention and intervention,it is expected to prevent rural college students from becoming psychological weak.

How to design a graceful campus with its culture and landscape respect is always a hot research topic of contemporary campus environment construction because the campus is very essential to promote the harmonious development of people’s physical and mental health. for the design of campus, the most important issue is to make the green landscape become the carrier of cultural heritage. The center square of campus is the core of space in the campus area, which is the key carrier to reflect the campus culture and the essence of environment.“Harvest Square” is the front part of the campus in northwest A&f university, which takes green as theme to show the cultural taste and campus features. The article takes this square as an example to elaborate its design ideas, in order to explain the landscape design of front greening square in campus.

Most volunteer organizations in universities focus their attention on urban communities and residents,but neglect rural *** universities have responsibilities and conditions to serve rural areas,and should bring into play their leading role. 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.
