The invention discloses a straw mushroom culture medium and a method for circularly cultivating straw mushrooms. The straw mushroom culture medium comprises 70 to 90 weight percent of Chinese medicament dreg, 10 to 30 weight percent of straws and a production increasing agent with the dose of 5 to 10 kg / m<3>, wherein the production increasing agent is prepared by mixing the following components in percentage by weight: 0.006 to 0.01 percent of vitamin B1, 15 to 20 percent of superphosphate, 40 to 60 percent of quick lime, 1.5 to 2 percent of magnesium sulfate, 0.2 to 0.4 percent of zinc sulfate, 0.2 to 0.3 percent of boric fertilizer, 0.2 to 0.4 percent of triacontanol and 22 to 37 percent of starch. By the straw mushroom culture medium and the method for circularly cultivating the straw mushrooms, resources can recycled; energy is saved due to short fermentation time of the medium; the medium can increase yield of the straw mushroom, can improve the quality of the straw mushroom and can increase the flavonoid content of the straw mushrooms; and by the multi-time circularly cultivating method, the utilization ratio of the medium is increased and production cost is reduced.

The invention relates to a cotton seedling substrate prepared from vinasse biogas residue and a preparation method thereof. The cotton seedling substrate comprises 7-9 cubes of vinasse biogas residue and 1-3 cubes of vermiculite, wherein the vinasse biogas residue is fresh mire which is generated after the vinasse is fermented in a biomass tank and biogas is generated, and the vermiculite is of clay mineral. The preparation method comprises the following steps of: sun-drying and dehydrating the vinasse biogas residue, carrying out first fermentation and secondary heterofermentation, air-drying leavening, mixing the leavening with the vermiculite, and then sieving to obtain the cotton seedling substrate. According to the invention, the problem that the vinasse biogas residue pollutes environments is solved, the vinasse biogas residue is used as the raw material of the seedling substrate, and the industrial chain of the circular economy for food processing is prolonged; the cost of the cotton seedling substrate per cubic meter is RMB 135 yuan; the cost of turf substrate raw material per cubic meter is RMB272 yuan; and therefore, the cost is reduced by more than 50%. The cotton seedling substrate has the following physicochemical indexes of: the grain sizes of 1-5mm of larger than or equal to 40%, organic matters with volume-weight of above 4.47 of 0.15-0.40g / m<3>, the total void of 60-70%, the pH value of 5.5-8.0, the conductivity of less than or equal to 80% us / cm, the total nutrient of 4.0%, and the moisture of less than or equal to 30% and reaches the optimal range of growth of seedling root systems.
