Coprinus comatus, also known as Coprinus comatus, is widely cultivated in northern China. However, due to the single cultivation season, the markets in winter and summer are rare and the production efficiency is difficult to improve. Taking advantage of the experience in vegetable production, coprinus comatus is cultivated in the off-season, which is during the high temperature period from June to August and the cold period from December to February. The cultivation of the entity can not be normally grown in the season. First, Coprinus species production 1. Medium formulation. The PDA medium is enriched, and the test tubes are subdivided into test tubes according to conventional methods, sterilized and inoculated. The cultures are incubated at 25° C. The mycelium is covered with slant over 6-8 days, and the original culture medium is made of wheat seeds. 2. Cultivation materials formula. 1 cottonseed husk 100%, plus 2% phosphate, urea 0.5%, lime 2%, carbendazim 0.1%, water amount; 2 corn cob 100%, plus urea 1%, lime 3%, carbendazim 0.1% , The amount of water; 3 cottonseed hull 60%, corn straw 40%, plus 1% lime, carbendazim 0.1%, gypsum 1%, water amount. The formulation can be flexibly adjusted according to the actual situation in production, but it must be ensured that the raw materials are not mild and not deteriorated. Second, the anti-season cultivation measures 1. Coprinus comatus at high temperature 30 °C, the base of mycelium thinning, autolysis. Therefore, during the high temperature period, we should try our best to create a cool environment, such as the establishment of a semi-underground mushroom shed. The shed is cold in winter and cool in summer. There are coverings on the walls and roofs, and long-grass plants are planted around the sheds to cool and cool the sheds. It also has the function of absorbing CO 2 to increase fresh air, installing forced ventilation and automatic water-moisturizing equipment. In places with good groundwater sources, it can also use underground water or reservoir bottom water to form a slow cycle in the mushroom shed, which can reduce the temperature. , And can increase the air humidity, if you can maintain the temperature within the greenhouse below 28 °C, select the heat-resistant Coprinus comatus species, naturally there will be high yield and quality mushroom output. 2. The temperature is lower than 8 °C without mushroom is one of the biological characteristics of Coprinus comatus, so the low temperature season should increase and maintain temperature within the mushroom shed 15-20 °C. Warming measures include digging deep sheds, thick coverings, and double membranes. When the temperature is below 0°C, coal fire walls, coal stove hot air, electric mushroom beds, furnace heating, and solar heating can also be used. Method: The boring machine is 20 centimeters deep, and digs the same thermal conductive tunnel with a depth of about 20 centimeters, and the width of the boring machine. The entrance and exit of the tunnel are all set at the outer end of the shed, and the depth of the entrance to the shed outside the shed is 2 meters. Diameter of 2 meters round pit, laying around the pit and pit bottom laying plastic film, reflective film layer, the top part of the pit roof according to the mushroom shed north-south slope, covered with double plastic film, so that it produces a heat pit, so When the sun is in the winter, the temperature in the pit can reach about 40°C. With the hot air active feature, the tunnel is naturally filled and the cold air in the tunnel is pushed out with the air. The outlet is provided with an exhaust passage with an internal diameter of 10 cm and a height of about 2 meters. The cold air can be exhausted through the exhaust passage. When the exhaust gas temperature reaches 25°C or more, the temperature in the tunnel can reach about 30°C. The contact between the boring earth and temperature exchange can increase the bed temperature to about 20°C. Every day at 9 o'clock, hot gases are generated, exchanged, and discharged. The temperature of the trampoline starts to rise sharply at 11 o'clock. The exhaust path is slowly closed at 14 o'clock to store the heat in a concentrated manner. The heat production pit is covered at 16 o'clock and the cycle is repeated daily. The ground temperature can be effectively improved, and the installation of heat sinks instead of snake tunnels can also be used. 3. Coprinus comatus can be used raw materials cultivation can also be used clinker cultivation. Raw material cultivation requires that the culture material be accumulated and fermented, the fermented material should be spread on the previously-prepared concrete surface, the material thickness is about 20 centimeters, and the seed is divided into 3 layers, and the seed amount is 15% of the culture material, sowing is completed, and the material level is leveled And slightly pressurize, cover 2 centimeters thick loam, until the mycelium is long and then cover the fine soil. The soil is first pre-wet with lime water, the earth material size is 0.8-1.2 cm, first covered with coarse soil, then covered with fine soil, spray water not to be too wet, so as not to affect the growth of mycelium, air humidity controlled at 80% -90%, 15 Days after the mushroom. Third, the fruiting period management budding period do not spray water to prevent mushroom buds caused by excessive water death. The fruiting body grows wet and airy, and the air humidity in the mature stage is kept between 90% and 95%. After the buds are unearthed, the growth rate is very slow. After growing to 3 cm, the speed is faster, generally 3-4 days can be harvested. That is, in the bud stage, the fungus ring just loosened, no anti-crimping scales appeared on the cap, and the unopened umbrella was harvested for an appropriate period of time. It was necessary to prevent the bacterial cap from becoming black and self-dissolving and losing the commodity value. When harvesting, the roots should be pulled up. The soil should be cut with a small knife and packaged in a bag.
