Continuous cropping soil disinfection and water spraying system

The invention discloses a continuous cropping soil disinfection and water spraying system, and relates to the technical field of soil disinfection. Comprising a plastic barrel body, a venturi fertilizer applicator, a watering main pipe and a water spraying pipe which are communicated through pipelines, a suction pipe of the venturi fertilizer applicator is communicated with the plastic barrel body, a main pipe of the venturi fertilizer applicator is communicated with the watering main pipe, the watering main pipe is communicated with the water spraying pipe, and the water spraying pipe is arranged between the surface of a furrow and a heat preservation mulching film. The continuous cropping planting soil is disinfected by combining the heat preservation mulching film, the Venturi fertilizer applicator, the water spraying pipe and the like, the heat preservation mulching film is mainly used for avoiding waste and pollution caused by the fact that a large amount of trichloroisocyanuric acid is volatilized into
