Agricultural nonpoint source pollution is becoming the major issue of ecological environment，but its dispersion，universality and other characteristics make it difficult to control it.The study analyzes the development of nonpoint source pollution caused by orchard planting in Jiangxi province，and presents the development status and technical advantages of the Vulpia myuros green manure.It is feasible to control the nonpoint source pollution with the Vulpia myuros green manure in the orchard.Although the application of the Vulpia myuros green manure technology is faced with problems such as difficulty in collecting seeds，high price，and weak awareness of ecological protection of fruit farmers，but the technology of Vulpia myuros green manure has strong applicability and obvious advantages，and the promotion effect will be very significant.The Vulpia myuros green manure role of controlling the nonpoint source pollution is in line with the ecological civilization construction.It meets the concept of green development in Jiangxi.Therefore，it has broad application prospects if the difficulties have been overcome.
