There are two kinds of management methods for mushrooming of ashwagandha: bag type and wild mushrooming. Bag type mushrooming - the long original base of the mushroom bag into the mushroom room, maintain the temperature 20 ~ 22 ℃, air humidity 85% ~ 90%, light 200 ~ 500 lux, 3 ~ 5 days after the removal of the ring, cotton plugs, upright on the bed frame, the mouth of the bag covered with paper, the paper sprayed with water, ventilation 2 ~ 3 times a day, each time for 1 hour. About 20 to 25 days later, the mushroom cover fully expanded, stoma elongation picking. When picking, the whole clump of mushrooms can be cut off with a small knife, and 2 to 3 tides can be picked in a row, with a bio-efficiency of 30% to 40%. Imitation of wild mushroom - wood chips as culture medium for the cultivation of mushroom bags, mycelium full bag, remove the plastic bag, the sticks are neatly arranged in the pre-dug beds, leaving appropriate gaps between the sticks, fill in the gaps and around the sticks, and cover the surface of the soil layer of 1 to 2 centimeters. This is a form of mulching cultivation, biological efficiency can reach 100% to 120%. This method is far better than the former (bag mushrooming), so it is emphasized here. Exhaustion time - The best period for the cultivation of Grey Mushroom in Tangshan is from November to the end of April of the following year. Because at this time, the air and soil bacteria, diseases and insects are not active and do not infringe on the mycelium, while the gray tree flower mycelium is resistant to low temperatures, mycelium connects closely and grows healthily, which is favorable for the absorption of nutrients by the mycelium. Low temperature period row of fungus under the ground despite the longer development period, but the mushroom early, high yield, can be completed before the rainy season, 80% of the yield, planted after the end of April ashwagandha because of high temperatures, fungi active, ashwagandha mycelium bag easy to infect, and will appear Sub-entities grow fast, single small, low total yield, vulnerable to high temperatures and rainstorms damage. The method of sterilization - ① site: choose the place with windward and sunny, high terrain, dry, not waterlogged, near the water source, convenient drainage and irrigation, away from toilets or animal pens. ② digging pits: the requirements of the east-west direction, dug 45 to 55 cm wide, 2.5 to 3.0 meters long, 25 cm deep pits, the distance between the pits is 60 to 80 cm, between which to repair the drainage ditch, so as to facilitate walking, management and drainage. ③Preparatory work before planting: after digging a good trench, you should first irrigate a large amount of water, the purpose is to retain moisture. After the water dries up, sprinkle a layer of lime on the bottom of the ditch and the help of the ditch in order to increase calcium and disinfection, then sprinkle a thin layer of trichlorfon powder on the bottom of the ditch and the help of the ditch, and finally lay a small amount of topsoil on the bottom of the ditch. ④Discharge sticks: Strip all the plastic bags of mycelium, discharge the sticks horizontally in rows and vertically in rows in the ditch, neighboring sticks should be next to each other, and there should be a gap between every 4 sticks. At the same time, by raking or padding the bottom of the ditch back to the soil, so that the discharge in the ditch of the upper surface of the mushroom stick flush. In this way, 4 to 5 rows of mushroom sticks can be discharged in the ditch. ⑤ Fill the gaps: Fill the gaps between the mushroom sticks and the mushroom sticks and between the mushroom sticks and the furrow helpers with soil to 1 cm above the mushroom sticks. (6) Flooding: put water into the pit to make the soil realized, with gaps or pits with moist soil leveling, keep the top layer of soil 1 to 2 cm thick. (7) package to help: with plastic film or nylon bags around the pit package tightly to prevent the pit side of the soil off. 2 months before the row of fungi on the ground also need to lay a layer of film in the borders, in the film covered with 5-7 cm soil layer, to mid-April will be within the borders of the film and soil shoveling, ready to mushroom management. ⑧ take shade: in the pit north side and the pit in the middle of the two crossbar, the middle crossbar from the ground 15 cm, the north side of the crossbar from the ground 25 cm, in the crossbar on the plastic sheeting and grass curtains, was the south of the low north high tilt. 4 months before the north of the plastic sheeting straight to the ground, and with the soil pressed tightly, east and west sides of the exhaust holes. ⑨ paving gravel: winter under the fungus when covered with floating soil and film to shovel out floating soil and film after paving gravel. Spread a thin layer of 1.5-2.5 cm diameter smooth gravel in the bed. Mushroom management - ① water management: in late April, when the natural temperature reaches 15℃ or above, fill the beds with water once, the amount of water is suitable for not having the bed surface about 2cm, and then automatically seep down and spray the water once a day in the morning, noon and night, the amount of water is suitable for moistening the ground, and try to spray to the space. According to the rainfall situation, drought every 5 to 7 days to watering, water can immediately seep down is appropriate, there is rainfall less irrigation. After the original base of the gray tree flower is issued, water spraying should be careful to stay away from the original base, to avoid washing away the yellow water droplets on the original base. When the ashwagandha grows up, you can spray water on the mushroom to promote the growth of the mushroom. Don't spray water on the roots of Grey Trefoil for 3 days after harvesting, so as to facilitate the re-strengthening of the mycelium and the growth of the next tide of mushrooms. In the high temperature season, it is also necessary to sprinkle water on the grass curtain and the open space outside the pit to reduce the temperature and increase the humidity. In the low season, it is better to use warm water that has been exposed to sunlight when spraying and irrigating, so as to keep warm. Rainfall in the rainy season, you can spray less water or no water spray, drought and heat need to be sprayed at noon during the day to increase a large water. ② temperature management: late April or early May to heat preservation, the night to cover tightly grass curtains and plastic sheeting, or grass curtains under the plastic sheeting on the top, and in the daylight when appropriate to extend the time of direct sunlight on the beds. late June to August high temperature and high temperature period should be cooled down to the main, you can use the water spray to cool down and increase the grass curtains on the cover to increase the degree of shading. Uncover the plastic sheet or grass curtain at night to grow in the open air, and then cover the grass curtain or plastic sheet and other coverings during the day when the temperature is high. ③ Ventilation management: after mid-April, the north side of the plastic sheet should be rolled up and stacked on the grass curtain, so that the north side of the long-term ventilation, every morning and evening to unveil the grass curtain ventilation for 1 to 2 hours. Pay attention to low temperature and windy weather to less ventilation, high temperature and rainy time to more ventilation, morning and evening before and after spraying water, appropriate increase ventilation. Ventilation should be coordinated with heat preservation, moisturizing and shading, and should not be unventilated or over-ventilated. During the period of differentiation of mushroom buds, there should be less ventilation and more moisturizing, and during the period of growth of mushroom buds, there should be more ventilation to promote evaporation. ④ Light management: use the method of supporting slanting frame to maintain stable diffused light for the growth of ashwagandha, and increase weak direct light by drying for 1~2 hours in the morning and evening every day. The production does not use too thick grass curtains to retain sparse direct light, avoid strong direct light during the mushrooming period, and do not remove the shade for the sake of heat preservation and convenient operation, resulting in strong light illumination of mushrooms. ⑤ Coordinated management of light, temperature, water and gas: these factors of light, temperature, water and gas must be executed in coordination, in different seasons, different periods and different weather conditions, as well as cultivation and management conditions, to catch the main aspects, but not to be neglected to the extent of deviating from the limits of the secondary aspects, and it is also necessary to create the conditions of the demand for other factors by means of the generalization of measures of any of these factors. For example, increase ventilation on rainy days to achieve moist conditions for mushroom production, and reduce high-temperature damage by increasing shade when dry and hot; uncovering the curtains for drying every morning and evening can be done at the same time as ventilation and water spraying, or picking mushrooms at this time. The deformed mushrooms of Grey Trefoil are mostly caused by environmental disharmony, such as the yellowing of the original base and the drying up of the mushroom without differentiation, which is caused by large ventilation and small humidity; the small scattered mushrooms are caused by small ventilation and lack of light; the Deerhorn Mushroom and Tall Mushroom, whose cap is shaped like a leaflet and whose differentiation is delayed, are caused by poor ventilation and excessive humidity; the yellow swollen mushrooms are caused by large water vapor, weak ventilation, or high temperature; the whitish mushrooms are mostly caused by weak light; the scorched mushrooms are caused by strong light and small moisture; the original base is not growing and has no moisture; the mushroom is not growing and the moisture is small; the mushroom has no moisture. The non-growth of the original base is mostly caused by low temperature and slow growth due to thick mulch, overwatering and cold watering; the thin-fleshed mushrooms are caused by high temperature, high humidity, poor ventilation and non-evaporation of the mushroom body; and the collapse of the medium is caused by high temperature and lack of ventilation resulting in the death of the mycelium. In short, the premise of high yield of Grey Trefoil is to coordinate light, temperature, water and gas factors to create suitable conditions for growth and development.
