Method for producing shiitake mushrooms by utilizing mulberry stalks, cassava residues and sugarcane leaves

Abstract

The invention provides a method for producing shiitake mushrooms by mulberry stems, cassava slag and sugarcane leaves. The method is a process that shiitake mushroom cultivation materials are used for conducting high-temperature fermentation in advance. The method comprises the steps that the cassava slag, the mulberry stems and the sugarcane leaves are crushed, lime and thermophilic bacteria are added in above mixture, water is sprayed after the mixture is completely mixed, the mixture is covered with a thin film for fermentation, then molasses, peanut bran and fish meal are scattered in the cultivation materials to be evenly stirred, then piling is conducted, fermentation in a film coating mode is conducted for two days, after two to three times of pile turning is conducted in this way, the cultivation materials are evenly stirred, the cultivation materials are heated to 70-80 DEG C, sterilization is conducted for 15 hours, then the temperature is dropped to the normal temperature and is kept 25-30 DEG C, then strains are inoculated, and after eight to ten days, the shiitake mushrooms can grow out. According to the method, the thermophilic bacteria are used for fermenting raw materials which can be rotten easily, the biological efficiency of the raw materials is improved, the yield of the shiitake mushrooms is increased, the temperature of a high temperature period is improved, the growing temperature of the shiitake mushrooms can be reached quickly, the mushrooms can be cultivated in the whole year, and energy consumption of a mushroom house is reduced.

Description

technical field [0001] The invention belongs to the cultivation technology of edible fungi, and relates to a method for producing shiitake mushrooms by using high-temperature bacteria to ferment mulberry stalks, cassava residues and sugarcane leaves. Background technique [0002] Mushroom cultivation originated in China and has a history of more than 800 years. Wu Sangong, a farmer in Longyan Village, Qingyuan County, Zhejiang Province, first invented the cutting flower cultivation method in the Song Dynasty, and it spread throughout the country. [0003] Growth conditions for shiitake mushroom cultivation: [0004] Temperature, in a humid state, the optimum temperature for the germination of basidiospores is 22-26°C. The temperature range for mycelium growth is 15-30°C, but due to the protective effect of wood, mushroom trees can survive safely in alpine mountains where the temperature is lower than -10°C or in low-altitude areas higher than 40°C, and mycelium will not d...

Problems solved by technology

[0013] The patent documents disclosed above have their own advantages, and they all provide different methods and culture substrates for cultivating shiitake mushrooms, and have also reached different requirements. The problem of planting shiitake mushrooms in winter requires the use of advanced medium such as wood chips or relying on temperature control in greenhouses or artificial temperature control to meet the growth needs of shiitake mushrooms, and the degradation of organic matter in raw materials is slow, the biological efficiency is low, and the yield of shiitake mushrooms is low.
