USE - Golden needle mushroom culture material.    ADVANTAGE - The culture material has low cost and simple preparation method, utilizes easy to obtain raw materials, contains nutrients that can satisfy growth requirement of needle mushroom, and is capable of cultivating golden needle mushroom at fast growing speed. The cultivated golden needle mushroom is dense, tender, delicious in taste, and rich in nutrients.    DETAILED DESCRIPTION - A golden needle mushroom culture material comprises 55-60 pts. wt. cotton seed hull powder, 30-35 pts. wt. corn straw, 20-22 pts. wt. Sorghum straw, 18-20 pts. wt. soybean straw, 16-18 pts. wt. broad bean shell powder, 10-12 pts. wt. rice bran powder, 20-22 pts. wt. dry duck manure, 18-20 pts. wt. dry chicken manure, 1-2 pts. wt. plaster, 1-2 pts. wt. sucrose, 0.5-0.8 pts. wt. nickel chloride hexahydrate, 0.4-0.5 pts. wt. cobalt chloride, 7-9 pts. wt. peanut shell powder, 6-8 pts. wt. sweet potato seedling powder, 4-6 pts. wt. limestone powder, 1-2 pts. wt. radix codonopsitis, 2-3 pts. wt. pawpaw, 2-2.5 pts. wt. purslane, 1-2 pts. wt. clove, 0.8-1 pts. wt. pumpkin vine, 1-2 pts. wt. lychee seed, 4-5 pts. wt. nutrient additive, 0.3-0.4 pts. wt. Effective Microorganisms (EM) bacterial liquid, and 2-3 pts. wt. honey. The nutrient additive comprises 0.5-0.6 pts. wt. ferrous sulfate, 0.3-0.5 pts. wt. sodium selenite, 0.6-0.8 pts. wt. calcium carbonate, 0.9-1.1 pts. wt. coix seed oil, 3-4 pts. wt. bower vine leaf powder, 1-2 pts. wt. yeast polypeptide powder, and 2-3 pts. wt. mushroom residue. The nutrient additive is prepared by adding bower vine leaf powder with 4-5 times water to extract, adding mushroom residue, heating at 60-65 degrees C for 30-40 minutes, drying, crushing, then adding rest materials, and mixing to obtain the nutrient additive product. An INDEPENDENT CLAIM is included for preparation of the golden needle mushroom culture material, comprising adding honey with 30-35 times water to obtain honey water; adding and crushing radix codonopsitis, pawpaw, purslane, clove, pumpkin vine, lychee seed, dry duck manure, and dry chicken manure and mixing, then spraying honey water onto the mixture with stirring and adjusting water content to 30-35%, adding EM bacterial liquid, sealing, and fermenting for 15- 20 days at 30-35 degrees C to obtain fermented material; cutting corn straw, Sorghum straw and soybean straw, soaking into clear water for 3-4 hours, then taking out and drying, adding the fermented material, and the rest raw materials, adding water with stirring till water content is 60-65 wt.%; and putting mixed material into polypropylene plastic bag and sterilizing with steam at 100 degrees C to obtain the product.
