How to do a good job
During the cultivation process of mushroom bag materials, color conversion is a crucial step. Once the color conversion fails, the production will be significantly reduced and the quality will be degraded, which will lead to no income. 1, the reason for failure. If the amount of bran used in the formula of the culture material is too much, the nutrients of the mycelium are excessive; the hyphae have not reached the physiological maturity when the bag is taken out of the bag, and the mycelium continues to vegetatively grow after the bag is unleashed, resulting in the hyphae being prolonged; the temperature is high after the bag is taken out (25° C. (above) caused air-type hyphae on the surface of the bag surface; the temperature was lower (below 18°C) after bag removal, and the surface airborne mycelium grew slowly or stagnated; the humidity in the mushroom bed was insufficient or the shade was not enough after the bag was removed, resulting in bacteria Rods lose water, inhibiting the normal growth of surface aerial hyphae; pests and diseases occur. The first three conditions often cause the bacteria bars to turn too slowly, the bacilli are too thick, the color is dark, the mushrooms are significantly delayed, the mushrooms are small, the individuals are large, the tide times are not obvious, and the proportion of autumn mushrooms is greatly reduced. The latter three conditions can lead to non-reversal or light coloration, and the bactopoid is too thin, which has a poor protection effect. The production is characterized by rapid fruiting, small flowers, and many malformed mushrooms, resulting in a significant decrease in quality and yield. 2, preventive measures. 1 The formulation of culture materials controls the proportion of bran in 20%-22%, and the amount of bran used in mulberry wood chips should be less than 20%. 2 When the hyphae reach the physiological maturity, they are taken out of the bag again. The signs are: the lumps in the bag change from hard to soft, the inoculated points become brown, and the mushroom primordium is formed. Suitable for the maturity of the mushroom sticks, it is easy to control the color change, and the mushroom is clean and tidy. 3 Grasp the cultivation season, when the bag is taken out, the temperature should be 20-25°C. When the bags are exposed to high temperature in the hot weather, the shades should be thickened, ventilation should be strengthened, and the mushroom bed and the environment humidity should be raised to prevent the dehydration of the mushroom sticks; in case of low temperatures, the film should be tightly sealed to increase the thickness of the fence on the windward side, and the cold air can be blown directly. Into the mushroom bed, before and after noon to increase the temperature. 4 After the bag is unpacked, the mushroom bar loses protection, easily loses water, and is invaded by pests and diseases. Therefore, the mushroom bed must be disinfected and kept in a moist state before the bag is taken out, so that the edge is covered and the humidity is maintained at 60%. -95%. Farmers who have cultivated shiitake mushroom for the first time can use the method of bagging and then gradually removing the bag after the bag is broken, which is time-consuming but easy to grasp.
