Problems solved by technology

Due to the weak ability of Flammulina velutipes to decompose lignin and cellulose, this formula with wood chips as the main nutrient source is not conducive to the nutritional needs of Flammulina velutipes growth. The ratio reaches 30-40%. Because the cottonseed hulls are extremely prone to insects, pesticides should be used to prevent insects, making it difficult for the produced Flammulina velutipes to meet the requirements of organic food
In addition, the preparation method of culture medium in the prior art is to simply pulverize the raw materials, the particle size is relatively large, and the raw materials of the culture medium are mixed unevenly, resulting in unbalanced nutrition, irregular growth of Flammulina velutipes, extended harvest period, and reduced quality.

Abstract

The invention discloses an industrial bottle-cultivation white needle mushroom culture medium and a preparation method thereof. The sources of the raw materials of the culture medium are abundant, and the culture medium has low cost, is reasonable in proportioning, and is favorable for the growth of needle mushrooms. The culture medium comprises the following raw materials in percentage by weight: 42 to 48 percent of corncob, 13 to 17 percent of rice bran, 18 to 22 percent of aspen wood saw dust, 6 to 8 percent of red-skin winter wheat bran, 2.5 to 3.5 percent of corn flour, 2.5 to 3.5 percent of bagasse, 1.5 to 2.5 percent of liquoric root dregs and 4 to 6 percent of gypsum. The preparation method comprises the following steps of: crushing the raw materials of the needle mushroom culture medium into granules; mixing the corncob, the aspen wood saw dust and the bagasse according to the ratio, performing primary stirring for 15 minutes, and adding water gradually; adding other raw materials according to the ratio, performing secondary stirring for 30 minutes, and adding the water gradually; and testing moisture content by using a moisture tester until the moisture content is between 62.5 and 64 percent.

Description

technical field [0001] The invention relates to edible fungus cultivation technology, in particular to a Flammulina velutipes cultivation technology. Background technique [0002] Chinese invention patent application CN1879463 discloses a culture medium of Flammulina velutipes. The formula and weight ratio of its raw materials are as follows: 30-40% of cottonseed hulls, 30-40% of sawdust, 25-30% of bran, and 1% of calcium carbonate. Due to the weak ability of Flammulina velutipes to decompose lignin and cellulose, this formula with wood chips as the main nutrient source is not conducive to the nutritional needs of Flammulina velutipes growth. The ratio reaches 30-40%. Because cottonseed hulls are extremely prone to insects, pesticides should be used to prevent insects, making it difficult for the produced Flammulina velutipes to meet the requirements of organic food. In addition, the preparation method of the culture medium in the prior art is simply crushing and processing...
