Culture medium for agrocybe cylindracea and preparation process of culture medium

Abstract

The invention discloses a culture medium for agrocybe cylindracea. The culture medium comprises the following components in parts by weight: 30-50 parts of cottonseed hulls, 80-120 parts of modified straws, 20-30 parts of bran, 35-45 parts of furfural residues, 50-70 parts of cake fertilizer, 15-25 parts of compound fertilizer, 1-2 parts of growth regulator and 0.3-0.5 part of antifungal agent. The compound fertilizer is prepared by mixing monopotassium phosphate, polypeptide urea and calcium superphosphate according to the weight ratio of 1:(0.5-0.7):(3-4). A preparation process of the culture medium for agrocybe cylindracea is as follows: pretreating the straws for 15-25h by using clarified lime water, regulating the pH value to 5.8-6.4, carrying out aerobic fermentation for 16-20d, then, mixing the straws with raw materials including the furfural residues, the cake fertilizer, the growth regulator and the antifungal agent, and carrying out irradiation sterilization by using Co60-gamma rays. Cellulose and lignin are converted into monosaccharide or disaccharide, so that the actual utilization ratio of the culture medium is increased, and the produced culture medium contains abundant extracelluar enzymes and is capable of promoting the fission and differentiation of the agrocybe cylindracea, shortening the growth period, inhibiting pathogenic infection and improving the yieldand quality.

Description

technical field [0001] The invention belongs to the technical field of edible fungus production and cultivation, and in particular relates to a tea tree mushroom culture medium and a preparation process thereof. Background technique [0002] Tea Tree Mushroom, the scientific name is columnar mushroom, is a kind of edible and medicinal fungus, fresh and delicious, high in nutrition, high in protein, rich in vitamins, mineral elements and a variety of essential amino acids. The effect of the spleen. Compared with other kinds of edible fungi, the activity of extracellular cellulase and laccase of tea tree mushroom is lower, and its ability to degrade cellulose and lignin is weak. Wild tea tree mushroom only grows on camellia oleifera. In the prior art, it is generally used as main raw materials to prepare tea tree mushroom medium with miscellaneous wood chips, cottonseed hulls and corncobs. Growth is slow. In addition, in the stage of germination and fruiting, it is easy to b...

Problems solved by technology

In the prior art, it is generally used as main raw materials to prepare tea tree mushroom medium with miscellaneous wood chips, cottonseed hulls and corncobs. Growth is slow. In addition, during the fungus and fruiting stage, it is vulnerable to the damage of Neurospora mold and mushroom fly, which reduces the quality and yield of tea tree mushroom

[0003] The patent with the application number CN201711025129.8 discloses a tea tree mushroom culture medium containing compound nutrients and its preparation method. The acid regulates the optimum PH, which not only provides sufficient nutrients for the growth of tea tree mushrooms, but also prevents the occurrence of bacterial pollution and pests. However, the price of camellia oleifera is relatively expensive, and its main purpose is to produce tea seed oil, with camellia oleifera sawdust as the main The cost of cultivating tea tree mushrooms is high, which reduces the original value and additional output value of camellia oleifera trees.

The patent application number is CN201410039506.3, which discloses a culture medium and cultivation method of tea tree mushroom. The nutritional components and medicinal value of camellia and hemp have been improved, but in terms of pest control, they have not yet reached the standard of professional cultivation, which is easy to cause pathogenic infection
