Eight attentions to the prevention and control of Agaricus bisporus

By strengthening the comprehensive management of the cultivation of Agaricus bisporus, creating an environment conducive to the growth of Agaricus bisporus and not conducive to the propagation of pests and diseases is the key to the growth of organic Agaricus bisporus.

1. Do a good job in environmental sanitation. Seed production and operators must establish a normal sanitation management system, constantly remove pollutants and disinfect the medicaments. All the equipment in the mushroom house, utensils and indoors should be cleaned and disinfected frequently. The mushroom room should be carefully watched and the clothes should be neat and tidy. It can be replaced in time.

2. Choice of disinfection method. It is preferred to use high-pressure steam sterilization, atmospheric pressure intermittent sterilization, pasteurization, and ultraviolet lamp sterilization. Physical disinfection is preferred to use alkali and phenolic drugs to avoid the use of heavy metal salts and other disinfectants. .

3. Handle the raw materials. The culture of Agaricus bisporus must avoid the accumulation of wood mold, wheat straw, cattle and horse dung, etc., and the plastic film or the felt should be protected from moisture. The above should be covered with rain or debris. Chicken manure, cattle and horse manure, rice bran, bran, cake and other probiotic molds should be sealed and stored. The culture material should be subjected to high temperature sterilization or fermented and fermented, and insist on good secondary fermentation. The covering material must be sterilized by steam or formalin.

4. Adjust the amount of water and pH. The water should be appropriate, the pH should be appropriate, and the adjustment should be checked at any time. The mushroom house should be well ventilated at all times, and the relative humidity of the air should not exceed 95%.

5. Keep the medium in a safe place. The bottle or the sterilized medium should be protected to prevent secondary pollution. Cover the gauze or film. Fumigation in the box should be scrubbed with new Jie Er and other potions to prevent dust pollution.

6. Strictly implement the operating procedures. The vaccination work is technically strong, and you must be patient and meticulous. Remember to rub the adhesive tape. For all utensils and containers, you can wash them cleanly, fumigation can be fumigation, you can rub alcohol with alcohol, and you can burn with a flame of alcohol.

7. Use artificial physical methods to control pests and diseases. If black light is used to trap mosquitoes and flies, the culture material is fully fermented to kill nematodes and mosquitoes, and the decayed parts are removed and disinfected with lime water. Improve the environment, adjust the temperature (such as lowering the temperature to prevent pecan bacteria), humidity (such as reducing the humidity to prevent the pathogen) (such as lowering the pH to prevent white mold, etc.).

8. It is strictly forbidden to use pesticides with great toxicity. Do not use organic mercury preparations or organophosphorus preparations and pesticides that remain for a long time and are not easily decomposed. Plant insecticides such as pyrethrum, fish vine, tobacco extract and microbial insecticides (such as Bacillus thuringiensis and Beauveria bassiana) are preferred. )Wait.
