Their physicochemical properties and the content of alkaline nitrogen, available phosphorus and available potassium were measured. The organic compound substrates F2 （vinasse-cow dung 60-20） and Z2 （vinasse-biogas residue 60-20） were selected by analyzing the influence of auxiliary materials on the substrate properties via PLS-DA model and assessing the fertilization efficiency of each compound substrate via fuzzy evaluation method. Then, substrates F2 and Z2 were mixed with soil at the ratio of 3∶7 to make seedling substrate, respectively; and their application potentials were evaluated by seed germination and seedling growth test. The results showed that the physicochemical properties of each organic compound substrate could meet the requirements of conventional substrates, and the substrates F2 and Z2 had the higher evaluation coefficients of fertilization efficiency in the cow dung group and biogas residue group respectively. Among the mixed seedling substrates, the “F2+soil” group had the highest seed germination rate, and the germination potential and germination index were significantly higher than the “Z2+soil” and control groups; the whole plant length, height and fresh weight of seedlings were obviously superior to those of the seedlings in the other two groups. In sum, the organic compound substrate F2 had good performances, and the seedling substrate obtained by mixing F2 and soil could be used to cultivate high quality AMM seedlings and had good application potential.

The pot experiment was carried out with different sowing depth and soil water content treatments. Water was replenished by weighing, and germination potential, rate of emergence, seedling growth and physiological indexes were determined. The results showed that the sowing depth and soil water content had a significant influence on the seed rate of emergence and seedling growth. The germination potential and rate of emergence were higher when the sowing depth was 0.31~0.61 cm. When the seeding depth was 0.61~0.92 cm, the chlorophyll content of seedling leaves was higher and the stress resistance of seedlings was better. The germination potential and rate of emergence were higher when soil water content was 60.71%. The seedlings grew better when soil water content was 53.35%~60.71%. The seedlings had better stress resistance when soil water content was 38.62%~53.35%. The chlorophyll content in seedling leaves was higher when soil water content was 45.98%~53.35%. The suitable sowing depth of Cyathula officinalis seeds was 0.61 cm. The rate of emergence was higher and the emergence was orderly when soil water content was about 60.71%. After seed emergence, the seedling grew vigorously, the chlorophyll content of leaves was higher, and the seedlings had better stress resistance when soil water content was about 53.35%.
