First, the selection of fine varieties is mainly used in the low-temperature varieties, the species 0 °C low temperature in winter not dead mushrooms, mushrooms do not occur, mushrooming neat, rapid tide, stable and high yield.

Second, raw material selection and processing selection of fresh moldy corn stalks crushed to about 3 cm, bean crushed into a small section of 0.5 to 1 cm, exposure 2 to 3 days.

1. Formulated corn straw 60%, soybean straw 20%, wheat bran 17%, sugar 1%, gypsum 1%, quicklime 1%, 50% carbendazim WP 0.15%. Feed water ratio 1:1.2 to 1.3, pH 8 to 10.

2. Ingredients mix the main ingredients with gypsum and sugar dry 2 times, then add lime and mix well, carbendazim added to the water for wet mix, mix well, the water content in the fingertips between the hands with water droplets appear Do not dribble it properly.

3. Stacking materials Weigh the materials according to the formula ratio, mix thoroughly and stack them on the plastic shed membrane, the humidity is kept at 60% to 65%, the stacking material is 1 to 1.5 meters high, the width is 1.5 to 2 meters, and the length is not limited. Put on the plastic film, and use the soil to compact the moisturizing fermentation around and keep the room temperature at 20-25°C. Place the heap in the warm shed to ferment under the conditions. When the feed temperature reaches 60°C, turn it on for 10 hours and turn it over. When it is turned, turn it inside out, turn inside out, turn it upside down, and turn it over so that the fermentation is even. After 3 to 4 repetitive batch fermentations, the broth will become ripe after producing aroma.

Third, the loading culture selection of 25 cm and 50 cm low-pressure polyethylene barrel, with a sewing machine needle on the barrel to play 3 rows of micro-holes, with a line tied to the end of the barrel into the bag after loading. The strains are hand-pulverized into agglomerates of apricot nucleus and red jujube. The first step is to put a layer of bacteria, then a layer of material, and compact the culture material into a cylinder by hand. At the same time, a 2 to 2.5 cm thick bamboo tube is inserted in the center of the bag, and then the material is loaded, and the edges are pressed by hand. A total of 5 layers of 4 layers of material are used. The amount of the two bags is 1/2 of the total amount. The total amount of seeds used accounted for 20% of the cultivation material. Finally, the bamboo tube was pulled out to leave gaps in the center of the culture material to accelerate the growth of mycelia. After the material bag is installed, it is gently moved to the mushroom house and arranged in the form of "goods". The code is placed on 2 to 3 layers. The temperature of the bacterium room is controlled at 15 to 20°C and the feed temperature must not exceed 25 to 28°C. The indoor light should be dark, the relative humidity of the air is 55 to 60%, and the ventilation management is strengthened. The hyphae can cover the bag about 20 to 25 days.

Fourth, after the mushrooming management mycelium full of bags, about 3 to 5 days or so, there are mushroom buds emerged, enter the mushroom management, management of the main links are: take off the bag covered earth wall cultivation, control of temperature and humidity, prevention Pollution, timely harvest.

1. Take out the bag and cover the earth wall to cultivate a layer of mellow soil (or nutrient soil). Use this code as a trapezoid. The whole wall of the scum is covered with thin mud and no gaps can be left. The top is painted with a width of 10 cm. sink.

2. Temperature and humidity management increase the temperature difference between day and night (5 ~ 10 °C) 2 ~ 3 days, and spray water on the ground and walls, but can not spray to the wall, maintain 80% relative humidity, while maintaining the mushroom The air in the room circulates and there is a certain amount of scattered light. After 5 to 7 days, it is necessary to increase the amount of water spray and the number of water sprays. The relative humidity of the air is increased to 90% to 95%, and the temperature is maintained at 12 to 17°C. After 3 to 5 days, the head tide mushroom matures.

3. The main diseases to prevent pollution are virus disease, rot disease, brown spot disease, and mycorrhizal fungi disease; pests that cause great harm to Pleurotus ostreatus are wireworm, mushroom fly, mushroom mosquito, and wild grasshopper. To prevent pests and diseases, first of all to do a good job in the disinfection of the cultivation site, so that clean and thorough; the second application of pasteurization principle to maintain the temperature of 60 °C culture material for 10 hours, so that the culture material is fully sterilized and decomposed, eliminate bacteria The third is to use healthy, non-viral strains to reduce the incidence of viral diseases; Fourth is to use clean water, to avoid long-term presence of bacteria film, effectively prevent the occurrence of bacterial diseases; Local pollution should be promptly removed and partially disinfected with lime powder. Sixthly, 50% dichlorvos emulsifiable concentrate should be dipped in a shed and outdoor in a mushroom house to effectively drive out flies and mosquito pests.

4. Timely collection of young fruiting body primordial growth can be harvested in 5 to 7 days. Generally, when the edge of the cap is slightly inside, it is harvested, and the quality of the harvest is too late. After the first tidal mushroom is harvested, the material surface is cleared in time to clear the dead mushroom, rotten mushroom and other impurities, and then the same tide mushroom can be managed.
