High-yield cultivation techniques of Auricularia auricula

Auricularia auricula is yellow back Auricularia auricula, which is common in our daily life. It tastes delicious and is loved by many people. It is distributed all over China. It grows on various trunks or rotten wood. It has the effect of clearing lung qi and relieving pain and activating blood circulation. The following parent farming network will explain its high-yield cultivation techniques.

1. Cultivation time

There are many cultivation methods of Auricularia auricula, but now mainly use clinker bag cultivation and plastic greenhouse wall type two, these two methods are time-saving and labor-saving, but also high yield. According to its cultivation characteristics, generally in early February bag hair fungus, ear at the end of March, summer high temperature, not conducive to mycelium growth, so in August bag hair fungus, ear at the end of September.

2. Cultivation substrate

Auricularia auricula cultivation raw material requirements dry, clean, no mildew, no hard debris, etc., mildew, moisture, hard debris raw materials will affect its yield. The cultivation raw materials can be prepared with corncob 47%, sawdust 40%, bran 10%, calcium superphosphate 1%, lime 1% and gypsum 1%. Because the water absorption of the main raw materials corncob and sawdust is poor, it is necessary to pre-wet in advance, and then all the raw materials are mixed according to the proportion, and then fully stirred to make them moist, and the water content is controlled at about 60%. Then it can be bagged. Before bagging, it should be stuffy for one day, and stirred once to make it absorb water evenly. The loading requirements are tight and moderate, and the upper and lower tightness is consistent.

3. Sterilization inoculation

Auricularia auricula is usually sterilized by steam at atmospheric pressure, maintaining a temperature of 100 degrees for 12 hours at atmospheric pressure. Then cease fire, use the remaining temperature to stew for 12 hours, you can completely sterilize, when filling the pot should not be too full. Leave room for steam to cover the entire space for optimal sterilization. The inoculation is carried out in an aseptic environment to prevent secondary infection. People should be disinfected before inoculation. After inoculation of hyphae, the bag should be closed in time and gently compacted to fully combine the strains with the cultivation substrate.

4. Post-management

In order to ensure good bacteria production, disinfection should be paid attention to in the greenhouse, and a layer of quicklime should be sprinkled on the ground to inhibit the growth of other miscellaneous bacteria and the harm of snakes, rats and mosquitoes. In addition, the inoculated bags should be stacked into wall stacks with a height of about 10 bags. The distance between stacks should be maintained for convenient ventilation and management. Auricularia auricula should be produced at low temperature, avoid high temperature, avoid burning bacteria phenomenon, 20-25 degrees is appropriate, the highest should not exceed 28 degrees Celsius, in the mycelium cultivation period is best for the dark environment, try not to see light.

The above is the high-yield cultivation technology of Auricularia auricula brought by the pro-farming network. When cultivating Auricularia auricula, pay attention to the growth period, check frequently, and solve the problems in time to avoid failure.
