Non-pollution edible fungi production technology
1. The ambient temperature of the culture bacteria should not exceed 28°C. In addition, cultured strains should not be stored for more than two weeks at room temperature. 2. Effectively grasp the time and temperature of the culture medium to prevent the destruction of nutrients, and the pH should be appropriate. 3. Always change the medium, such as peptone, wheat bran, potatoes and other medium materials to be used interchangeably. 4. The original species should not be used up once, should be used in batches, and the remaining cryopreservation should prevent excessive passage. 5. Each year should choose a large individual, normal growth, robust pest-free fruiting body for a tissue separation, from which to choose superior and inferior, expand the growth of inoculation. Second, comprehensive prevention and control of pests and diseases By strengthening the integrated management of edible fungi cultivation, creating an environment suitable for the growth of edible fungi unfavorable to the breeding of diseases and insect miscellaneous bacteria is the key to the production of pollution-free edible fungi. 1. Do a good job in environmental sanitation Seed production and operations personnel must establish a normal hygiene system, continuously remove dirt and disinfect it. Mushrooms, utensils and all equipment in the room should be cleaned and disinfected regularly; care should be taken to ensure that the soles and clothes are clean and tidy when entering and leaving the house. 2. Choice of disinfection methods Preferentially, high-pressure steam sterilization, atmospheric pressure batch sterilization, pasteurization, and UV lamp sterilization are used for disinfection. For chemical disinfection, the use of alkalis and phenols is preferred. Avoid disinfectants such as heavy metal salts. 3 handle raw materials Edible fungus culture materials must be protected from mildew and pests; piles of sawdust, fodder, horse dung, etc., should be covered with plastic film or moisture-proof from the felt, and the top must be covered to prevent rain or debris from falling into it; Bacteria, bran, cake, etc. are prone to mold, should be sealed storage; culture materials should be sterilized by high temperature or fermented maturity, culture materials into the mushroom house, post-fermentation: cover material must be steam or formalin disinfection. 4. Adjust water consumption and pH The moisture of the medium should be appropriate. The pH should be suitable and be tested and adjusted at any time. Mushrooms should always be well ventilated, and the relative air humidity should not exceed 95%. 5. Protect the medium properly The material bottle or sterilized culture medium of the pan should be protected to prevent secondary pollution; cover with gauze or film, fumigation into the container should be scrubbed with benzalkonium chloride and other medicines to prevent contamination. 6. Strictly enforce the inoculation procedure The inoculation work is very technical, must be patient and meticulous, avoid touching the adhesive tape; for all utensils and containers, washable should be washed clean, fumigation can be fumigation. Can rub alcohol to wipe alcohol, can use the flame of the flame of the alcohol lamp to use the flame to burn; for a large number of cultivars can be two inoculation cooperation, the good flame blockade, one holding bottle, one inoculation, not leave the lamp, With accurate. 7. Use artificial physical methods to control pests and diseases Such as the use of black light trap to kill mushroom fly, mushroom mosquitoes; culture materials fully fermented (60 °C, 2 ~ 4 hours) to kill nematode and gall midge; remove corrosive sites, with lime water disinfection. Improve the environment, adjust the temperature (such as reducing the temperature to prevent endophytic walnuts), humidity (such as reducing the humidity control of Streptomyces), PH value (such as reducing the pH control white mold, etc.). 8. The use of highly toxic pesticides is strictly prohibited Do not use organic mercury or organophosphorus pesticides and pesticides that have long residual time, are not easily decomposed, and have irritating odors. Pesticides such as pyrethrum, fish vines, tobacco leachate and microbial insecticides such as Bacillus thuringiensis and Beauveria bassiana are preferentially used. 3. Spray pollution-free mushroom fertilizer Spraying mushroom noodles with 0.1% peptone and 0.3% yeast extract solution can make the mushroom body hypertrophy and promote moisture transfer. The best effect is at room temperature 14~16°C. 2. Spraying of decomposed human waste The human excrement is boiled for 20 minutes, watered 10 to 20 times spray, or fresh horse urine and cow urine, boiled until no foam, watered 7 to 10 times spray. If the mushroom mouth has mushrooms, after spraying, spray with water again. 3. Spray rice vinegar In the late period of the mushroom growth, spraying 300 times of edible rice vinegar on the noodles surface, once a day for 1 to 3 days before harvesting, can generally increase production by 6%, and the color is more white. 4. Spray culture leaching solution Fermentation of dry material 5 kg, add boiling water 50 kg soaked, sprayed after cooling to the residue, can extend the peak period of fruiting, and fruiting body hypertrophy. 5. Spray mushroom water Take 2.5 kg of washed mushrooms and add 15 kg of water. Cook for 15 minutes. Remove the water and apply 20 kg of water to spray. This can extend the peak period and make the fruit body hypertrophy. 6. Spray soybean milk Soybeans 1 kilogram, ground milk into the water 75 to 100 kilograms, the filtrate sprayed mushrooms surface, and then sprayed with water 1 time. 7. Spray glucose, calcium carbonate solution A solution containing 1% glucose and 0.5% calcium carbonate was sprayed at less than 18°C ​​to promote mycelial growth.

First, prevent the degradation of edible fungi to prevent the degradation of bacteria, can increase production, reduce the occurrence and development of pests and diseases, reduce the amount of pesticides, is the basis for the production of pollution-free edible fungi.
