Pastoral cultivation of Auricularia auricula

The consumption of cultivation resources of Auricularia auricula is too large, which is disadvantageous to the long-term development, and the per unit yield is low, and the benefit is unstable. The field cultivation of bag material was carried out in Lincheng Edible fungus Farm of Hebei Province, and after 3 years, the key points of cultivation, the success rate of inoculation, ear yield and quality were greatly broken through, and a group of ear farmers were instructed to go on the road of becoming rich. 1. Bag-making in cultivation season should be carried out from early October to early November. At this time, the room temperature is 1824 ℃, the air relative humidity is 65%, and the temperature is getting lower and lower, and the activity of miscellaneous bacteria is at a low ebb, which is beneficial to the feeding of Auricularia auricula mycelium and early spring. two。 Raw material ratio bag cultivation Auricularia auricula raw materials are mainly broad-leaved tree sawdust, raw materials require fresh, no mildew. Formula one: 80% sawdust, 10% rice bran, 8% wheat bran, 1% calcium carbonate and 1% brown sugar. Formula 2: 60% sawdust, 28% rice husk powder, 10% wheat bran, 1% calcium carbonate and 1% brown sugar. The water content of the culture material is 55%. 3. Choose fields with good ventilation, sufficient sunshine, convenient water sources, no pollution sources, waterlogging prevention or dry land as ear fields. The border bed is shaped like a tortoise back, 120 cm wide and unlimited in length, and the edge ditch is a sidewalk. The bed floor is covered with hay to moisturize and prevent sediment from eroding the earphones. No need to cover the film, open-air show. 4. Row tube and ear management in early February, remove the good fungus tube from the ear field, choose sunny or cloudy days to pierce the hole. Pierce 150 ear holes (use 0.6 cm nail heads to make piercing tools). The earphone can be sprayed with fine water 7 days after piercing, once in the morning and once in the evening. After half a month's management, the earpiece can be picked in eight or nine minutes. Pick a batch to change the head once, make both ends of the ear evenly, and promote the mycelium to form a fruiting body. Headphones should be kept dry and wet, dry and wet alternately. After a batch of ear harvest, raise bacteria for 1 week, and stop spraying water, wait for the formation of the second batch of ears, manage as usual. A total of 3 and 5 batches were picked. In the new method, it takes only 4 months from the appearance of black fungus to the end of harvest, and the cost is slightly lower than that of bag planting of Lentinus edodes. The bag produces 50 grams of dried fungus, and the income of each bag is 2.3 yuan per bag calculated at the market price of 46 yuan / kg. There is also a gap in the seasonal market, so the products sell well and the economic benefits are considerable.
