Microbial seedling-growing medium and production system thereof

The invention discloses a microbial seedling-growing medium and a production system thereof. The microbial seedling-growing medium comprises medium raw materials and water, wherein the medium raw materials comprise straw, vermiculite, a nutritional agent, coconut coir and thoroughly-decomposed cow dung, the nutritional agent and the water are added into a semi-finished medium product obtained after raw material treatment, high-temperature sterilization, raw material mixing and solid-liquid mixing are conducted, and even mixing is conducted. No chemical pesticides or fertilizers are added intothe microbial seedling-growing medium, thus the environment is not polluted, and the microbial seedling-growing medium can improve soil, improves the fertilizer efficiency, makes soil around roots ofplants loose and free from hardening, retains water and fertilizers, and promotes well growth of the roots; and by means of the microbial seedling-growing medium, vegetable seedlings can come out evenly, the seedlings are stro
