example 1

[0020] Example 1, in conjunction with the specific implementation method, a kind of preparation method of Bailing mushroom cultivation substrate is described in detail:

[0021] (1). The mass ratio of the matrix formula used: 60% of cottonseed hulls, 25% of corncobs, 5% of corn flour, 6% of bran, 1% of gypsum, 2% of lime, 1% of superphosphate, material and water ratio 1:1.2. (2). Substrate preparation: According to the proportion of the formula, select 60% cottonseed hulls, 25% corn cobs, 6% bran, and 5% corn flour without moths. 25% crushed, then soaked with 1% gypsum, 2% lime, and 1% superphosphate for pretreatment, then mixed the culture material with water, and mixed well, so that the water content of the culture material reached 60%, and the pH value was 8.5, and then piled up and fermented . (3). Substrate treatment: Pile the treated compost into a strip-shaped pile with a width of 1.1-1.5m, a height of 1.2-1.5m, and an unlimited length. m, hole diameter 6cm, punch 5 ...

example 2

[0022] Example 2, adopt the formula of the present invention to carry out the cultivation concrete steps of Bailing mushroom as follows:

[0023] (1). Select the cultivation season and cultivation site. Cultivate in well-ventilated, clean and pollution-free places in the northern region, and the vegetable greenhouses are mushroom houses. Inoculate from August 20 to September 30, and fruit from November 20 to April of the following year.

[0024] (2). The formulation of the matrix. Formula: 60% cottonseed hulls, 25% corn cobs, 5% corn flour, 6% bran, 1% gypsum, 2% lime, 1% superphosphate, material to water ratio 1:1.2.

[0025] (3). Preparation of matrix. According to the recipe requirements, select 60% cottonseed hulls, 25% corn cobs, 6% bran, and 5% cornmeal without moths. 1%, lime 2%, superphosphate 1% soaking pretreatment, then add water to the compost and mix well, mix well, make the compost water content reach 60%, pH 8.5, and then carry out compost fermentation.

Abstract

The invention relates to a preparation method for a pleurotus nebrodensis culture medium, and belongs to the technical field of edible fungi culture. According to the present invention, components in an medium formula and a preparation method for the medium are provided, wherein the components in the medium formula comprise, by mass, 60% of cottonseed hulls, 25% of corn cob, 5% of corn powder, 6% of wheat bran, 1% of gypsum, 2% of lime, and 1% of calcium superphosphate, a mass ratio of the materials to water is 1:1.2-1.3, and the preparation method comprises: selecting culture materials with no toxic change and no insect biting according to the ratio, treating the culture materials, and carrying out piling fermentation to achieve purposes of the present invention. The preparation method of the present invention has the following advantages that: corn cob and other agricultural wastes are utilized so as to easily achieve agricultural clean production, complete resource utilization and sustainable development; and the prepared culture medium is applicable for high quality rapid growth of pleurotus nebrodensis variety.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a method for preparing a cultivation substrate of Bailing mushroom. Background technique [0002] Bailing mushroom, also known as white asafoetida, is a white variety of erythrina, and it is a new breed of rare edible fungus developed in recent years. Bailing mushroom has a large and white body, delicate meat, good taste, strong fragrance, and nutrition Rich, according to the measurement, the protein content of Bailing mushroom is as high as 14.7%, containing 18 kinds of amino acids, low in fat, rich in vitamin D and various mineral elements and trace elements, and the selenium content is as high as 6.8%. At the same time, it is rich in Active substances such as fungal polysaccharides can eliminate accumulation and blood stasis, clear away heat and detoxify when eaten, and can treat stomach diseases and typhoid fever, lower blood pressure, enhance human immunity...
