The method of one-time fruiting of bag-grown shiitake mushrooms

Abstract

The invention relates to a method for fruiting bag-cultivated mushroom at one time. The method comprises the operation steps of mushroom selection, inoculated culture, test tube expanding, cultivated species inoculation, cultivated species culture, strain treatment, raw material pretreatment, material batching and stirring, mushroom stick packaging, mushroom stick sterilization, mushroom stick inoculation, mushroom stick cultivation, mushroom stick coloring, mushroom stick pretreatment and mushroom stick fruiting. Coarse and fine culture base materials of a mushroom stick produced by utilizing the scheme are reasonably matched, nutrient substances are full, and perlite in a formula has the functions of holding moisture, ventilating air, regulating the potential of hydrogen and providing multiple microelements needed by the growth of the mushroom; meanwhile, oak chips and apple chips are mixed with corncobs, so that the ventilation of the mushroom stick is improved, the biotransformation rate of the mushroom is improved favorably, biotransformation of the mushroom stick can be promoted by virtue of a great number of microelements in canal mud, the uniformity of mushroom stick fruiting is improved by pre-cooling a mushroom bag, the mushroom stick fruiting speed is increased by utilizing the stimulation of the difference between pre-cooling temperature and external environment temperature, and the biotransformation rate is improved by 10-20 percent.

Description

technical field [0001] The invention relates to the field of edible fungus production, in particular to a production method of shiitake mushrooms, in particular to a method for one-time fruiting of shiitake mushrooms grown in bags. Background technique [0002] The common name of shiitake mushrooms is Xianggu, Shiitake, Pingzhuang, and Shiitake. It is a fungus food containing high protein, low fat, polysaccharides, multiple amino acids, and multiple vitamins. It has the effects of lowering blood pressure, blood fat, and cholesterol. It is known as "King of Mushrooms", "Queen of Mushrooms" and "Crown of Vegetables" have high nutritional value. As the second largest edible fungus in the world, shiitake mushrooms have played an irreplaceable role since ancient times. [0003] The cultivation of shiitake mushrooms is mainly based on bag cultivation. After mixing raw and auxiliary materials such as wood chips and bran into bags, they are inoculated with shiitake mushroom strains...

AI Technical Summary

Problems solved by technology

From the date of inoculation, it takes 90 days for the growth and cultivation time and 30 days for the color change of the conventional formula of shiitake mushroom sticks to produce mushrooms. The whole cultivation and mushrooming cycle takes 120 days. Including the loss of a large number of nutrients, and the bacteria culture period is too long to easily cause mold infection and bacterial infection

[0005] 2. The mushroom sticks have a long period of fruiting

[0006] 3. The biotransformation rate of the fungus stick is low

At present, mushroom production consumes a large amount of nutrients during the 4-month culture, color change period and 6-month fruiting period, resulting in a low biotransformation rate of mushrooms. Generally, 2 catties of dried mushroom sticks, the most fresh mushrooms are 1 catties, biological The conversion efficiency is about 50%, which is far lower than the biotransformation efficiency of Pleurotus ostreatus, Flammulina velutipes and Pleurotus eryngii
