DETAILED DESCRIPTION - Mushrooms culture medium comprises 30-35 pts. wt. tea residue, 25-30 pts. wt. barley straw, 70-75 pts. wt. cotton seed shell powder, 20-22 pts. wt. sorghum straw powder, 10-12 pts. wt. potato leaves powder, 2-3 pts. wt. sugar, 0.5-0.6 pts. wt. potassium fulvate, 0.2-0.3 pts. wt. amino acid chelated magnesium, 0.2-0.3 pts. wt. amino acid chelated zinc, 3-4 pts. wt. semen biotae, 2-3 pts. wt. radix rehmanniae, 1-2 pts. wt. dwarf lilyturf root, 3-4 pts. wt. Gardenia, 2-3 pts. wt. white comfrey, 12-13 pts. wt. sticky rice, 14-45 pts. wt. Gelatin and 8-9 pts. wt. nutrition additive, which comprises 10-11 pts. wt. medicated stone, 4-5 pts. wt. vinegar, 6-7 pts. wt. bean, 0.3-0.4 pts. wt. finger citron oil, 3-4 pts. wt. biogas and 5-6 pts. wt. duck blood. The nutrition additive is prepared by soaking medicated stone in hydrogen peroxide for 3 hours, and then drying the obtained material at 150 degrees C to obtain modified medical stone powder. The obtained material is mixed with remaining raw material to obtain the finished product. An INDEPENDENT CLAIM is included for a method for preparing a mushrooms culture medium, which involves:    (A) extracting semen biotae, radix rehmanniae, dwarf lilyturf root, Gardenia and white comfrey with water for 40-50 minutes, and then filtering them;    (B) crushing tea residue;    (C) adding sticky rice with water, and then grinding them;    (D) adding sucrose to the obtained material, and then mixing the obtained material with gelatin;    (E) heating the obtained mixture at 75 degrees C, and then mixing them with all the obtained material;    (F) pressing the obtained into 14-15 cm diameter and 30-32 cm length;    (G) putting the obtain material in polyethylene plastic bag, and then adding water the bag; and    (H) sterilizing the obtained material at 100 degrees C and normal pressure to obtain the finished product.
