Poria cocos cultivation material and preparation method thereof

The invention provides a poria cocos cultivation material and a preparation method thereof. The cultivation material comprises, by weight, 25-35 parts of pine sawdust, 20-30 parts of rice bran, 15-24parts of soybean meal, 10-15 parts of bagasse, 2-4 parts of glucose, 5-10 parts of potato skin powder, 5-10 parts of dried radish leaves powder, 5-10 parts of dried lettuce leaves powder, 2-3 parts ofstarch, 0.2-0.5 part of ascorbic acid, 0.3-0.8 part of polyving akohol, 0.8-1.3 parts of hydroxypropyl methylcellulose and 60-110 parts of water. Compared with the prior art, the using amount ratio of raw materials is controlled to make the nutrients of the cultivation material abundant, carbon source, nitrogen source, phosphorus source and mineral elements which meet the growing demands of poriacocos are provided to promote the growth of the poria cocos, and the yield is improved; primary raw materials are chip and easy to obtain, and wastes are turned into treasures, which is green and environmentally-friendly; prepared ascorbic acid particles can maintain a weak acid environment of the cultivation material with the pH of 4-6 to promote the growth of the poria cocos.
