The invention discloses a live water infusion system of salviae miltiorrhizae and a cultivation method thereof, and belongs to the technical field of cultivation and infusion of Chinese medicinal materials. The infusion system comprises a water tank, wherein the water tank is connected with a nutrient solution liquid inlet pipe, a tap water pipe and a liquid outlet pipe; the tap water pipe and theliquid outlet pipe are arranged on the opposite side wall of the water tank; the tail end of the liquid outlet pipe is provided with a plurality of drip irrigation pipelines; and each drip irrigationpipeline is also provided with a plurality of nano microporous pipes. The cultivation method comprises the following steps of: preparing a salviae miltiorrhizae cultivation fermentation nutrient solution by using a fermented composite bacterial agent; ploughing in-depth, preparing soil, applying the organic fertilizer, ridging as a cultivation bed, sequentially pre-embedding the nano microporouspipes into the cultivation bed, and laying the bamboo charcoal powder and fine slag on the nano microporous pipes; planting the salviae miltiorrhizae seedlings on the built cultivation bed. Accordingto the live water infusion system of salvia miltiorrhiza and the cultivation method thereof, the soil is improved, the problem of continuous cropping obstacles is solved, full-automatic irrigation with high precision and no soil selectivity is realized, and is convenience and reliability.
