Main points of cultivation techniques of black fungus in hanging bag

Hanging bag black fungus, named after the way of hanging and placing. Under the same area, the number of the fungus is 4 to 5 times that of traditionally planted fungus. Since the growth process of black fungus produced in the greenhouse is less affected by the weather, the quality is pure, pollution-free, and the economic benefits are considerable. However, there are technical problems such as difficulty in ventilation, difficult control of greenhouse temperature, and easy occurrence of deformed ear pieces in production. The following will introduce you to several major cultivation points of black fungus in hanging bags.
Main points of cultivation techniques of black fungus in hanging bag:
(1) Bacteria selection
Choose black and thick, rootless, disease-resistant, heat-resistant strains.
(2) Selection of bacterial bags
To choose a thin bacteria bag, the bacteria bag generally chooses polyethylene bags, which has good shrinkage and is not easy to separate the bag material.
(3) Ingredients
The ratio of thickness to fine sawdust is: 70:30; moisture content is 65%; small materials and accessories are 10-15% more than that of ground pendulum cultivation. , 280 catties of rice husk flour, 80 catties of cornmeal, 32 catties of gypsum, and 29 catties of white ash (lime).
(4) Hanging bag method
Tie the two ends of the three ropes, and then put the fungus bags in one by one, and isolate them with a plastic sheet or a small self-made iron ring. Using this method to hang the bags is easy to operate, save labor, and is not easy to breed bacteria.
(5) Initial management of hanging bags
The time for the hanging bag fungus to enter the shed should be reasonably arranged according to the temperature in the local greenhouse. The bag can be hung when it is thawed at a depth of 0.3 meters underground. Prevent the bacteria bag from being frozen at night, and prevent the bacteria bag bag material from being separated due to high temperature during the day. Ventilate once in the morning or at night, the temperature in the shed should not exceed 25 ℃, and it should be cooled in time when it reaches 30 ℃ (the roof should be covered with a shading net). The water spray time is 2-3 minutes, and the humidity of the bacteria bag must be maintained. The humidity in the shed reaches about 85% to prevent the aging of the blade from affecting the output. The mushroom bag in the greenhouse should not be too dense, because it is not easy to ventilate, which will affect the quality and reduce the yield when the ear is released.
(6) Budding period management
Humidity should be the focus. At this stage, you can consciously water at low temperature to control the growth rate of the fungus, so that the fungus grows thicker and the ear shape is better. The ground in the shed should be kept wet and watered regularly to ensure the surface humidity of the bacteria bag. Use shade nets to adjust the temperature in the shed. After entering the exhibition period, appropriately extend the ventilation time, remove the shading net, increase the light, use the plastic sheet to control the temperature, and strengthen the ventilation. 4-5pm, put the plastic sheet down. Water after the bag is cool. The first watering amount should be large to keep the fungus moist, and stop watering after fogging. Remove the plastic sheeting at 6-7 in the morning, alternating dry and wet to increase production.
