2. Hanging bags dig 1.3 meters deep and 1 meter wide in the yard. Both ends of the groove must also be dug up to the two sides of the diffuse slope. A 2 cm thick wooden stick is used to hang the material bag on the ditch, and the ditch is sprayed with a watering can a day or two before the hanging bag.
With a 1.3-meter-long string, each of the two ends is tied to the mouth of a sack, and it is placed on a wooden stick in the ditch, and the sack falls into the ditch. In order to make full use of the space, the bag can be divided into four layers. The method is: two ropes as a group, one rope bag is adjusted at one or four layers, another is at the second or third layer, and so on. Ensure that the distance between the bag and the bag is between 10 cm and 15 cm, so that the microclimate between the bags is uniform.
3.Management 1 After hanging the bag, spray water in the ditch and on the bag so that the moisture content in the material is not less than 55%. To prevent exposure to strong light and maintain moisture in the ditch, cover the sparse plant straw and cover the plastic film. At the beginning of 5 days to 6 days, the relative humidity in the ditch is not less than 90%, after which the primordium occurs until the ear piece grows within 4 to 5 days, the humidity is not lower than 85%, and the ear piece grows to maturity within 78 days. The humidity is not Less than 90%. In short, except for the spraying of water one or two days before or after the first ear picking, the rest should be sprayed with moisture every day. Rainy days cover the ditch to prevent excessive water in the ditch. The temperature in the 2nd ditch is preferably 22°C to 25°C, and it is usually adjusted with a covering on the ditch. The concentration of carbon dioxide in the 3 trenches must not exceed 0.03%, otherwise the ear chip differentiation will be affected. Although the diffuse slope at both ends of the ditch can promote the circulation of air, it should be ventilated once every few days. 4 The growth of black fungus seed bodies also requires a large amount of scattered light and a certain amount of direct light, sufficient illumination, thick ears, dark color, good quality and high yield, so the position and light receiving of the bags are changed every few days. direction.
Selenium
is an indispensable trace element to maintain the normal function of
the human body. Selenium deficiency in the human body can lead to
various diseases. Modern scientific research
proves that selenium has anti-oxidation, enhances human immunity,
effectively removes harmful garbage, promotes human health, and delays
aging.
