Compared with the cultivation by direct seeding cultivation, the cultivation of Coprinus comatus in the Coprinus comatus bag has the advantages of easy examination, easy control of the temperature and humidity of the germinating environment, improvement of the success rate of germination, and is easy to intensively produce. Since coprinus comatus mycelium has strong stress resistance and is not susceptible to aging, hyphae can remain viable for a long period of time. Therefore, as long as the conditions are met, a large number of bags can be produced and good bacteria can be produced, and they can be arranged in appropriate seasons. Cultivation of mushrooms. The germination can be managed in the following four specific periods.
First, the management of the germination period This period of 3 to 5 days, to maintain the optimal growth temperature, in order to restore rapid growth. The strains are easily damaged and dehydrated when they are smashed. If they encounter high temperatures (above 40°C), they are easily burned, and if they are exposed to low temperatures, they will be delayed in growth. General raw material cultivation temperature can be controlled at about 20 °C, after 3 to 4 days, inoculated around four weeks to grow a neat and dense mycelium, which is germination. This period of management to shading, insulation based. Raw materials are easy to grow mucilage, clinker is prone to orange blanching. Therefore, it is important to mix ingredients, process and interior disinfection.
Second, the expansion of the colonization period of the management planting expansion period is also called the cover growth period, takes about 10 days. When the bacteria germinate, they quickly grow and occupy the culture medium and become the winners in competition with the bacteria. During this period, the mycelium grows vigorously, the metabolism is enhanced, the carbon dioxide increases after decomposing the substrate, and the oxygen demand is large. The management points are for heat dissipation and ventilation. Mainly. 5 to 7 days after inoculation should be inverted, the bed should be uncovered, at the same time check the pollution and deal with it in time. Ventilation and heat dissipation time is best carried out when there is no wind and air is calm, or it is carried out in sunny weather. To prevent the invasion of bacteria, the procedure can be exempted when the temperature of the culture material is not high. In this period, the temperature of the culture medium is generally 3°C~5°C higher than that outside the bag, so the surface temperature of the bag must not exceed 25°C. Appropriately about 20°C, the hand feels coolness is better, and the heat feel is not good, hot burn occurs. Burning bacteria phenomenon.
Third, the safe growth period of the management of the safe growth phase is also called the elongation of the hyphae, the mycelium covered the surface of the culture material, continue to extend the growth of the culture material until the culture material is full of mycelium. If the temperature is higher, the mycelium grows faster and the hyphae become weaker. In order to obtain thick mycelium, ventilation and cooling are required during this period. After 5 to 20 days of inoculation, a large amount of heat-dissipating phase of the culture material has passed. The mycelium of the coprinus comatus grows vigorously, and the oxygen demand is large. Ventilation is very important. The surface of cultivated mycelium is white and dense, and it is neatly stretched forward; thin and weak mycelium can produce mushrooms but the yield is not high.
Fourth, the management of mature mycelium maturation period is also called hyphal reeling period, when coprinus comatus full of mycelium growth material, the hyphae will continue to grow, showing the color further thick white. Especially when the temperature during the safe growth period is high and the hyphae are weak, it is necessary to continue growing so that it can mature as soon as possible. This period generally takes 4 to 5 days. After the maturation period is over, the hyphae stop growing and begin to kink to form primordia. This period is the key period for transformation of mycelium to fruiting bodies. The key points of management during this period are: (1) Increase the light, remove the shade, use light to inhibit the growth of mycelium, and promote the kinks of the mycelium; (2) Increase the humidity and relative humidity of the air More than 85%; (c) reduce the temperature, increase the temperature difference. If the above three conditions can be satisfied in time, it can shorten the maturity period, otherwise it will extend the maturity period and delay the mushrooming.
