Five innovations in family seed production of edible fungi
Innovate the raw materials of seed production and simplify the traditional and conventional PDA medium mixed with potato, glucose, Agar and so on. The innovation is a general medium for all-nutritious and high-nitrogen bacteria, which is made of wheat, grain, corn or tree branches as raw materials and coated with strain coating agent. This medium can not only graft mother seed, but also original seed and cultivated species, and the source of raw materials is convenient, which is not only money-saving, but also practical. The raw material cost of a mother culture medium is only 3 cents, and the raw material cost of a bottle of original seed or cultivated seed is only about 20 cents. Innovate the sterilization method to simplify the mother and original culture medium: put it in a high-pressure sterilizer and keep it under 21.2 kg steam pressure per centimeter for 30 minutes for 40 minutes, innovate for 40 minutes when the steam is sprayed from the pressure-limiting manhole in the Supor household pressure cooker, and remove after 10 minutes of heat. Innovate the atmospheric pressure equipment, simplify the sterilization equipment of the cultivated seed medium in the atmospheric pressure sterilizer (soil steamer) for 8 hours, and put it into the space sterilization package (about 30 yuan can hold 500-800 bottles per bag) for 3 hours for 4 hours. Innovate the inoculation method to simplify the method of closed inoculation with formaldehyde, potassium permanganate and other drugs after disinfection and sterilization in the inoculation box or inoculation room, and innovate to use an open aseptic inoculator for edible fungi. No electricity, no drugs, no alcohol, no disinfection and sterilization, directly and randomly carry out open inoculation and transplantation of all kinds of edible fungi, with a finished product rate of more than 99%. Innovate clinker seed production and simplify the cultivation of edible mushrooms such as Pleurotus ostreatus, Coprinus comatus, Pleurotus ostreatus, etc., using clinker inoculated after steam sterilization in atmospheric cooker. The innovation is to use raw materials to directly bag and inoculate production. After loading, the aeration hole in the middle is permeable, and the original seed with full nutrition and high nitrogen (15% of the seed amount) is cultured at the right temperature. Through simplification and innovation, a series of equipment, raw materials, drugs and supplies needed for traditional seed production are eliminated, and thousands of yuan of investment can be saved. In particular, open inoculation avoids infection of mycelium by disinfection drugs, damage to operators and environmental pollution, and the strains produced are particularly resistant, with a high temperature of 40 ℃ and a low temperature of-25 ℃. The success rate for propagation and cultivation is 100%, and the seed production period is shortened from 30 to 40 days to 8 to 10 days.

Main points of inoculation technology of edible fungi
Inoculation is one of the key links in the production of edible fungi. If the inoculation technology of female fungi is not up to standard, it will cause contamination of miscellaneous fungi, and the survival rate is low and all previous efforts are wasted, let alone cultivation. Whether it is strain isolation, passage or propagation, it must be carried out under aseptic conditions in strict accordance with aseptic operating procedures. The specific points are as follows: 1. Personnel quality 1.1 Vaccination personnel should have the spirit of seriousness, meticulous, self-consciousness and responsibility for the cause. 1.2 Inoculators should firmly establish the concept of sterility and should not be lucky.

Method for processing preserved fruit by edible fungi
Edible fungi are rich in nutrition and delicious in taste. Besides fresh food, processed into dry products, salted and canned, they can also be deeply processed and utilized to make various preserved fruits, condiments, sweets and wines with unique flavor and rich nutrition, which is beneficial to further improve the economic benefits of edible fungi. Here are a few ways to process mushrooms into preserves. 1. Preserved white mushroom 1. Formula: 80 kg of fresh white mushroom, 45 kg of white granulated sugar, 0.15 kg of citric acid. 2. Selection of materials: choose 8
