1. Mouthwash arrangements. This technology is not strict with the vegetable cultivars in the existing vegetable greenhouses. It takes the period from March to May in winter and spring for the supply period. In May, the shed can be vacated. From June to September, straw mushroom production can be arranged. That is, according to the physiological characteristics of high temperature and short cycle of straw mushroom, when the temperature in the region is stable at more than 25°C and the relative humidity of air is stable at more than 80%, it can be cultivated by using the existing idle vegetable greenhouses to cultivate straw mushrooms in the high temperature period. Times. After the end of September, it will continue to arrange autumn and winter vegetables production.
2. Key technologies. 1 training materials preparation. Straw mushroom production usually uses waste cotton, cottonseed husks, corn cobs, corn stalks, rice straw, etc. as the main culture material. Flammulina velutipes growers can use cultivar cultivated mushroom as the main cultivation medium, which not only solves the post-treatment problem of some cultivated cultivars of enoki mushroom, but also reduces the production cost of straw mushroom. Press Mushroom Wet Scrap: New waste cotton: Lime: Water = 20:2:1:4 Prepare the culture material, 55 kg for each square meter.
2 heap material. According to the formulation requirements of the culture materials, the required raw materials are fully pre-wetted and mixed well. The water content is suitable for pinching the water droplets by hand, and then piled into a stack of material 70 cm high and 1 m wide. Use a wooden stick to make several vents to the bottom of the pile. The stockpiles were covered with a film. When the temperature rose above 70°C two days later, the stock was turned over and the contents were turned to the outside. The outside material was turned inside and the water was added. After the temperature rises to 70°C, it is maintained for one more day, and then it is turned one more time. The fermentation temperature is used to fully kill the bacteria in the waste and decompose the organic matter in the waste. After 6 days, the fermentation material required no sour odor, dark brown color, and white actinomycetes mycelium. With 5% lime water to regulate the moisture content of about 65%. The fermented stock piles were spread and cooled to about 35°C before they could be inoculated.
3 greenhouse preparation. Prepare a greenhouse before packing. Greenhouses are sprayed with carbendazim after clearing the garden and shed 2 to 3 days. Plowing and exposing for 3 to 5 days before cultivation. When the sheds are tanned, they are smashed and flattened, and then dried for 1 to 2 days. Trampoline. According to the width of the greenhouse for the lateral haze, generally 1 m wide and 10 cm deep, depending on the length of the venue. Open a drainage ditch on each side, the ditch is 20 cm deep and 30 cm wide, and the excavated soil is on both sides. The distance between pipa and pipa is not less than 40 cm. The middle pipa is used as a road for management and harvesting. The greenhouse is covered with a double shade net, and the shade net can touch the ground directly on both sides. Take a small arch above the raft. Cover the net and non-woven fabric on the small arch. A deeper gully ditch should be dug around the site to prevent water intrusion and insect infestation. Two buckets are placed in the shed to preheat the water temperature.
4 shop inoculation. Before inoculation, spray 1% lime water or sprinkle a layer of lime in a pot. Spread a layer of material in the pot. The thickness is 2 cm, the layer of bacteria is spread on the edge, and then a layer of 10 cm thick material is spread. The remaining strains, the amount of strains 1-2 bags / square meter. When preparing materials, it is not appropriate to make a photo, but it must be made into a turtle shape with a low edge in the middle. After the end of sowing, cover a layer of plastic film, cover the straw curtain and shade net in time outside the greenhouse to avoid direct sunlight.
5 germs management. The fruiting temperature of the mushrooming period is controlled at 30~35°C, the relative air humidity is controlled at about 85%, and the film is shaken twice a day for ventilation. After the waiting surface is covered with mycelium, the film is removed, a layer of 1 cm thick (sterilized) fine soil is covered, and the temperature and humidity are kept moist with the water in the shed. The small shed is ventilated for half an hour every day and can be released after one week. mushroom.
6 fruiting management. After the hyphae climbed out of the soil, the water was filled with mushrooms, and the water temperature was required to be about 30°C. Cooling well water was not available, and the air humidity was about 90%. When the humidity is small after the emergence of mushroom buds, no watering or direct water application is required. The water spray mist should be changed. After each water spray, the air can be ventilated for 20 minutes. The air circulation is required and the oxygen is sufficient. Mushrooms need scattered light, the light is too weak to form fruit bodies, and the light is too strong to inhibit the growth of fruit bodies.
7 timely harvest. From inoculation to harvesting for 11 to 12 days, the harvest period is 3 to 5 days, and the peak period can be harvested twice a day. The principle of harvesting is to harvest large and small crops and harvest them in clusters. After the first batch of mushrooms were harvested, they should not be watered first. After 2 days, the soil was watered with mushrooms to manage the mushrooms. After 4 days, the second batch of mushrooms could be harvested. Due to high temperature, rapid development, and timely harvesting, otherwise the value of the commodity will be lost after the rupture of the veil: the mushroom will continue to grow, and the impurities in the base of the straw mushroom should be immediately removed with a small knife, and the grades should be graded well. Sell ​​as soon as possible.
8 waste disposal. The first two cultivation wastes need to be cleared out of the greenhouse. They can be used as fertilizer in other vegetable greenhouses or in open fields. The last cultivation waste can be directly used for deep plowing in sheds and used as improved soil in sheds.
