Method for cultivating Uricularia polytricha using cotton stalk

Abstract

The invention relates to a method for utilizing cotton stalks to cultivate Auricularia polytricha in the technical field of edible fungi cultivation. The technical proposal of the method is that: raw materials that forms culturing materials are allocated according to parts by weight: 80-90 parts of cotton stalk powders, 5-15 parts of bran, 3-5 parts of ordinary superphosphate, 1.5-3 parts of land plaster and 0-1 part of sugar; dry materials after allocation and 100-150 parts by weight of water are mixed and steamed; and then the fermentation is carried out and the pH value of the culturing materials is 5-6; discolored Auricularia polytricha strains are inoculated and cultivated by adopting wheat groat strains; the spawn running cultivation is carried out for 35-45 days under the temperature of 20-25 DEG C; the Auricularia hastening and the Auricularia growth are carried out under the temperature of 20-33 DEG C. The invention takes the wasted cotton stalks as main materials of the culturing materials, by matching with a moderate amount of nutrient substances and according to the growth characteristics of the Auricularia polytricha, a cultivating method which is scientific, reasonable and is easy to be popularized is provided from the strain selection breeding to the strain cultivation. The Auricularia polytricha cultivated by the invention has the advantages of low cultivation cost, high yield, sound quality and short vegetation period.

Description

technical field [0001] The invention relates to a method for cultivating fungus by using cotton stalks in the technical field of edible fungus cultivation. Background technique [0002] With the development of edible mushroom cultivation technology, the selection of the main raw materials of the compost and the collocation of strains have become the focus of attention. A Chinese patent discloses "A Raw Material Formula of Edible Fungus Strains and a Process for Making Solid Strains" (CN1765172), the raw materials of which are 40-60% of bamboo sticks, 10-20% of sawdust, and 10-20% of cotton shells. , wheat bran 10-20%, corn flour 0.5-1.5%, calcium carbonate 0.5%. The production process is as follows: (1) making bamboo sticks and processing bamboo sticks; (2) mixing bamboo sticks with appropriate amount of corn flour and wheat husks for later use; (3) mixing sawdust, cotton husks, calcium carbonate and remaining corn Mix flour and wheat husks well, add water to adjust the wa...
