Abstract: With gradual acceleration of modernization，the earth is consuming more and more resources.Energy and environmental problems have become primary problems that must be solved in current social development.In order to promote rational use of resources，more and more rural areas have begun to explore recycling of biogas，straw and solar energy.In particular，a circulatory system for biogas，straw and solar energy was established by using recycling technologies in some rural areas rich in straw resources.Based on it，importance of recycling straw，biogas and solar energy，and application of the three recycling was discussed.Then how to carry out straw，biogas and solar energy recycling applications were analyzed.And it provides some reference basis for further research.
