Black fungus culture medium and preparation method thereof, and method for ensuring original strain inoculation survival percent of black fungus

Abstract

The invention discloses a black fungus secondary culture medium which is composed of corn cob particles, corn grains, wood dust, bran and lime. The black fungus secondary culture medium has the advantages of reasonable formula and balanced nutrition, and can well satisfy the nutritional requirements for black fungus. The corn cob is added, so that the cost of the culture medium disclosed by the invention is lower than that of other wood dust / corn grain culture media; and the bran content is increased, so that the black fungus hyphae can grow more vigorously. The invention also discloses a method for ensuring original strain survival percent of black fungus, which optimizes inoculation and culture techniques. After the inoculation, the strain survival percent is up to 100%, the inoculation survival percent of the original strain is ensured, the hypha growth rate is high, and the hyphae are white, thick, strong and vigorous and have strong growth potential.

Description

technical field [0001] The invention relates to a black fungus cultivation technology, a secondary black fungus culture medium, and a method for ensuring the survival rate of black fungus original seed inoculation. Background technique [0002] Black fungus is rich in protein and multivitamins. It has the effects of cleaning the stomach, reducing blood clots, and relieving coronary atherosclerosis. It has the reputation of "the meat of the vegetarian". With the continuous improvement of people's living standards, the demand for black fungus is also increasing. At present, a small part of black fungus on the market is collected wild, and most of them are artificially cultivated. There are two methods of artificial cultivation: segment wood cultivation and plastic bag material cultivation. Segment wood cultivation of black fungus seriously destroys forest data, therefore, the focus of current research is bagged cultivation. [0003] Generally, the production process of blac...

Problems solved by technology

The cost of this medium is still high, and the original species (secondary species) with higher corn kernel content is inoculated on the third-level strains, which is easily infected by miscellaneous bacteria in the process of cultivation and sales

[0005] Since it is difficult for black fungus to germinate in low-temperature seasons, most guidance materials now advocate top-temperature inoculation, that is, to inoculate quickly while the bag temperature is still hot, so as to improve the germination rate of the fungus. In the production process of this inoculation process, It is impossible to accurately measure the temperature of each bag, and the temperature of some bags is still relatively high. Although this method has the effect of improving the survival rate of black fungus species, this effect is a limit effect, and it is difficult to achieve a perfect survival rate. The other extreme is easy to appear, ignoring the characteristics of black fungus species that are not resistant to high temperature, black fungus species are easy to be scalded to death, resulting in a low survival rate of the original species inoculation
