Planting time and methods of Auricularia auricula cultivation techniques

Black wood must be familiar to many people, it is a common food in life. It can be seen in many parts of our country today. Black fungus is famous for its high edible value, so it sells very well in the market. At present, many people want to plant it, so before planting it, it is inevitable to understand its cultivation techniques.

Black fungus planting time

According to the temperature requirement of mycelium growth of Auricularia auricula, inoculation can be carried out when the natural temperature is stable above 5℃. During this period, the miscellaneous bacteria are in an inactive state, and the mycelium of Auricularia auricula can grow, which not only reduces pollution but also ensures sufficient vegetative growth period. Generally, the inoculation season is arranged during the period of "Jingzhe". Therefore, there is a saying in the old area that "cutting trees into nine, Jingzhe points bacteria". In recent years, some units have advanced the inoculation time to February, and the effect is also very good, and it is more conducive to labor arrangement. Even when it comes to low temperatures, hyphae don't freeze to death. When the temperature rises, hyphae continue to grow.

Black fungus cultivation method

Auricularia auricula strains are divided into sawdust species and cork species. Sawdust seed production is easy to inoculate trouble, while cork seed production trouble inoculation easy.

1. Inoculation method of sawdust seeds: first use a punching hammer with a 1.3 cm punch, belt punch or electric drill to punch holes according to the inoculation density and depth requirements, and then insert sawdust seeds into a small piece, with eight full degrees, and then cover the bark cover or cork with a 1.4 cm belt punch on the inoculation hole, and gently tap it flat with a small hammer.

2, cork strains: cork strains are prepared by bottling cork and sawdust culture medium in proportion. No corks or bark caps are needed for inoculation. When inoculating, first insert a little sawdust seed into the planting hole, and then knock in a cork seed.

Cultivation techniques of Auricularia auricula

1. Mix materials. Mix well to ensure that the water content is about 65%. Planting black fungus: bagging. Mechanical bagging, 17cm×33cm or 16cm×52cm low pressure polyethylene bag, 17cm×33cm bag after the sleeve of hard plastic collar, and then plug cotton plug, outside tied with kraft paper. 16cm×52cm bag method is the same as mushroom.

2. Vaccination. Inoculation can be carried out when the temperature of the material in the bag drops below 30℃. Inoculation shall be carried out aseptically. The inoculation procedure of 17cm×33cm bacterial bag is as follows: put the cooled bacterial bag into the inoculation box; wipe and disinfect the outer wall of the original seed bottle with 75% alcohol and put it into the inoculation box, and then fumigate with 5 g potassium permanganate and 10 ml formaldehyde per cubic meter for 0.5~1 hour. When inoculating, ignite the alcohol lamp, crush the original seed with sterilized tweezers, make the bottle mouth of the original seed face the bag mouth in the sterile area where the alcohol lamp is ignited, evenly sprinkle the seed on the surface of the material in the bag to form a thin layer, so that the mycelium of Auricularia auricula germinates quickly and occupies the material surface first to inhibit the infection of miscellaneous bacteria. Each bottle of secondary seeds can be connected to about 30 bags. The inoculation method of 16cm×52cm mushroom bag is the same as that of shiitake mushroom.

Harvesting and Drying of Auricularia auricula

After the fungus grows up, it should be carefully collected to ensure a bumper harvest. Ear and autumn ear to pick large and small, let small ear grow up and then pick, V ear to pick size together, because the high temperature in summer, pests, bacteria reproduce fast, will make mature ears eaten by insects and rot off. Ear picking time, it is best to harvest ears after rain, or in the morning when the dew is not dry and the ears are soft. When picking back, it should be diluted on the sun mat, dried once in the hot sun, and should not be turned over more when drying, so as not to cause fist ears. In case of continuous rain, first of all, we should take the method of grabbing and plucking, spread the collected wet ears evenly on dry thatch or dry fungus, let the thatch or dry fungus absorb a part of water, and then move out to dry together after the weather is fine. If the harvest can not come over, plastic film can be used to cover the ear frame, so that the fungus has grown up and then continue to rain draft, resulting in loss of flow rod.

In fact, as long as he understood the cultivation techniques of Auricularia auricula, it was relatively simple for Zi to plant it. Before planting, it is necessary to do a good job in site selection, and the management in the later stage also needs to be strengthened. Only after each step of work is done in place can we ensure its good growth and high yield.
