Abstract: This paper gives the introduction for the forage grass desiccation technology process by using solar energy innovation and its advantages in different views, such as technological theory and equipment as well as the contrast test between the forage grass desiccation technology process by using solar energy and the nature desiccation technology in the field of forage grass, which can solve the exiting problems of flowers and leaves as well as the nutrition loss by using the nature desiccation technology process in the field for forage grass. We do a prospect to the future of the forage grass desiccation technology process and equipment by using solar energy.
