Bags of black fungus are divided into spring and autumn. Because of the climate differences, autumn is mainly planted in the high temperature south. 1 Choice of ear bag time. The decomposition of cellulose, hemicellulose, and lignin in the medium by woody rot fungi is based on mycelium secreting various enzymes, and the enzyme is extremely sensitive to temperature. In terms of black fungus, hyphae are much more tolerant to low temperatures than high temperatures. According to the determination, the mycelium in the wood segment can safely pass winter at minus 30 to 40°C, and the high temperature will denature the mycelium protein and make the enzyme lose its activity. At temperatures between 28 and 32°C, mycelial viability soon declined. Therefore, the earrings of spring ear should be suitable for the local temperature of about 13 °C. After cutting the mouth, the original base period temperature of the fruit body should be controlled between 8 and 20°C. In the blistering winds and dry hot weather, it is not possible to pocket the cuts, but it is ideal after the rain is fine, the air is fresh, moist, and cool. 2 moisture management. Black fungus is a type of fungus, and the air humidity is not enough. The ear cannot grow normally without being wet and stretched. However, black fungus is also afraid of the characteristics of quail, if the ear swelling too much water, cell rupture, fruiting body will occur lesions. Pouch spring ear is divided into ear bud period, exhibition period and mature period in water management, and different water management should be adopted in different growth periods. The general principle is: Ear bud water management should be relatively small, air humidity should be maintained at 80% to 85% is appropriate. With the growth of ear buds, ear pieces gradually formed. At this time, the humidity management is preferably 85% to 95%. But it also depends on the temperature and the difference. If the temperature is low, the activity of the decomposing enzymes in the mycelium will decrease and the nutrients for fruit body growth will be insufficient. At this time, if the amount of water sprayed is large, the ear piece will “drink†more and “eat lessâ€, and its resistance The ability will inevitably drop, and bacteria bags will be easily taken by the bacteria. If the temperature is appropriate, the decomposing enzyme is active, the nutrient supply is sufficient, the consumption of water absorption by the ear piece also increases, and the fruiting body grows fast and exuberant. Ears should adopt large-humidity and large-ventilation methods during the mature period to accelerate their maturity. However, it is necessary to prevent high temperature, humidity, and ventilation from coexisting at the same time. If the growth of the lug is too slow due to lack of nutrient supply, it can be stopped for a few days to allow the lug to shrink and allow the hyphae to accumulate nutrients and then perform water management. 3 temperature management. In nature, the black fungus produced in the spring and autumn seasons is dark in color, thick in flesh, and of high quality. In V-ears, the ears are thin, light in color, and the disease is frequent and easy to flow. The reason is that the temperature factor is at work. The most suitable temperature range for the development of Auricularia auricula is 18-25 °C. It has been confirmed in practice that the temperature management of the growth of spring-grown black fungus fruit bodies should be adjusted to the lower limit of the suitable temperature of black fungus. This helps prevent the sudden appearance of hot weather to the fruiting body. 4 harvest processing. The mature black fungus ear piece grows up, the ear root contracts, the color changes from shallow to deep, or the white spore powder on the ventral surface of the ear piece has to be harvested in time. Before and after harvesting, pay attention to the following points: 1 When the fungus is nearly mature, pay attention to watching the weather forecast. At this time, it can be harvested in advance. Conditions can be mechanically dehydrated and dried or the bag covered with a film, etc. After harvesting and drying after the rain, in order to avoid bumper yields. 2 After harvesting black fungus, use scissors to cut the root pedicle, divide the flower-shaped ear into a single piece, and then rinse with clean water to dry. When drying, the root face should be face down and the ears should face upwards. When it is less than eight minutes, it can not be flipped and it will naturally shrink and protect the good shape to improve the quality of the goods.
