Key points of High yield of Coprinus comatus cultivated in greenhouse

Among the edible mushroom products, Coprinus comatus has delicious taste, tender and delicious, unique flavor, rich nutrition and medicinal value, which is deeply welcomed by consumers and has great potential for market development. Coprinus comatus production, as a new project in industrialization, is very suitable to be promoted in the adjustment of rural industrial structure. The rotation production of Coprinus comatus was carried out in the plastic greenhouse of vegetable planting base, and good economic benefit was obtained. 1 greenhouse sunshade uses vegetable greenhouse to cultivate Coprinus comatus, first of all, the greenhouse must be shaded. Grass curtain should be used to cover the surface of greenhouse in early autumn, and two layers of sunshade film can be used in late autumn or winter. In order to prevent the strong wind from blowing off the grass curtain, it is best to cover the surface of the grass curtain with a sunshade film. The film around the greenhouse is required to be able to lift and put down to facilitate ventilation. (2) to treat the cultivation of Coprinus comatus in the greenhouse where watermelons or vegetables were originally planted, get rid of insects before making the border bed, spray dichlorvos or fenvalerate pesticides, and the use of high toxic pesticides is strictly prohibited. The soil should be fully emptied before putting in the bag. It is appropriate to make three border beds in a greenhouse, each of which is about 90 cm wide; the pit depth of the bacterial bag is not more than 30 cm; after the pit is done, it is disinfected with dry loose lime. (3) the suitable growth temperature of Coprinus comatus fruiting body made by bacteria bag is 8: 30 ℃, and the most suitable growth temperature is 12: 18 ℃. Coprinus comatus cultivated in the north of Zhejiang Province can produce mushrooms after the end of September, so the mushroom bags made of Coprinus comatus are 15 cm × 32 cm low pressure polyethylene plastic bag after the middle of August. Culture material, formula A: cottonseed hull 90%, wheat bran 40.5%, corn flour 45.5%, gypsum 1%; formula B: miscellaneous sawdust 75%, wheat bran 15%, corn meal 8%, sugar 1%, gypsum powder 1%. Follow the usual method: mix the material? Bagging? Sterilized? Vaccination. After inoculation, bacteria were sent in a clean culture room, and at a suitable temperature, the hyphae grew full of culture material for about 40 days, and then moved into the cultivation shed to open the bag. (4) the biggest characteristic of Coprinus comatus is that it does not cover the soil and does not grow fruit body and is especially resistant to low temperature. the hyphae can be preserved for a long time in the low temperature environment. When opening the bag, we must pay attention to the temperature conditions at that time, whether it is suitable for the formation of Coprinus comatus fruit body. Coprinus comatus can form a fruiting body in about 15 days after taking off the bag and covering the soil. Coprinus comatus cultivated in vegetable greenhouse, the earliest time to put in autumn is in mid-September, and the most suitable time is from mid-October to the end of November. 5 soil covering method after the bacteria bag of Coprinus comatus is full of mycelium, under the condition of suitable temperature, you can take off the bag and put it on the mushroom bed, and cover the soil immediately at the same time. The covering material can be directly used with the soil next to the mushroom bed, which needs to be fully mashed and pre-wet. The best covering material is nutritious soil. One month before covering the soil, the field without pollution is selected, manure is added during ploughing, it is broken after natural accumulation and fermentation, and 1% lime is added to adjust the water content at 25% to cover the soil. 6 after the mushroom production management is covered with pre-wet soil, the mushroom bed is also covered with a small arch shed and covered with film to maintain soil humidity and ventilation. In general, the fruiting body primordium of Coprinus comatus will be formed after half a month, and the fruiting body is required to maintain high humidity and be ventilated frequently. The management focuses on temperature control, when the temperature exceeds 28 ℃, it is mainly to cool and humidify, to avoid the wind blowing directly into the bed during ventilation, so as not to affect the quality of mushrooms; when the temperature of the mushroom shed is lower than 15 ℃, it is mainly to increase the temperature and humidity, remove the sunshade material from the surface of the mushroom shed, and build a small arch shed in the greenhouse to promote the normal formation of the Coprinus comatus fruit body. After the first tide of mushrooms is picked, the bed surface is sprayed to get rid of insects, and sprinkled with dried lime powder to prevent miscellaneous bacteria. The most suitable harvest time for Coprinus comatus is the bud stage of Coprinus comatus, that is, the cap is tightly wrapped around the stalk, the ring is not yet loose or just loose, and the mushroom body is harvested when it is 60-70% ripe. The harvest height of large Coprinus comatus varieties is 1520cm, and that of common varieties is 815cm.
