Technology of planting auricularia auricula in greenhouse

Auricularia auricula is a dish that we often eat, it can be meat and vegetarian, and has high nutritional value, but also has the effects of tonifying qi and nourishing blood, moistening the lung and relieving cough, hemostasis, antihypertensive, anti-cancer and so on. The following editor will bring you the sharing of the technology of planting fungus in the greenhouse.

I. greenhouse construction and disinfection

First build the scaffolding, and then lay a layer of new brick on the floor of the shed, which is about 6cm thick. Before hanging the bag, use 10% concentration of caustic soda supernatant to spray and disinfect the plastic sheeting inside, around and on the greenhouse once.

Second, hanging bag

The bacterial bag began to enter the shed to rejuvenate the mycelium injured by the bag during transportation. after the mycelium grew into the bag, the light was increased for 3 to 5 days to induce the formation of auricularia auricula fruiting body. When brown rice granular ear base appears on the material bag, the hand bag is put into 0.2% carbendazim or 0.1% potassium permanganate solution and rotated several times for surface disinfection.

When the temperature of the greenhouse reaches 15 ℃, when the mycelia on the surface of the bag are all whitened, the bag can be opened to raise the ear. The quality of cutter head should be paid attention to when buying small hole punching machine, which directly affects the speed, miscellaneous bacteria rate and quality of the ear. The opening bag is suspended on the ear rack. The distance between the bag and the bag is 10~15cm. Follow the cut and hang the bag.

III. Management in the middle and later stages

A dry and wet alternating environment should be formed during the post-middle management period. It takes about 7 days for the primordium to grow out of the bag. in the dry season, the ear buds in the upper part of the bacterial bag near the outside of the shed will dry up, and these parts should be sprayed more and more frequently. At low temperature, the lower and middle parts of the bag will be contaminated by rotten ears and miscellaneous bacteria.

When the daytime temperature reaches 25 ℃, the plastic film and sunshade net around the greenhouse and the roof are all opened and the spraying time at night is prolonged. When the temperature reaches 27 ℃, it is necessary to increase ventilation in the shed, increase enough direct light, stop watering during the day, and the natural temperature in the second half of the night is the lowest, such as continuous pouring of cold water, high humidity and low temperature in the bacterial bag, spores are not easy to eject, and the ear lugs will be blackened and thickened.

IV. Disease prevention and control

When the ear bud grows to 1.5cm, the fruit body is evenly sprayed with 0.3% salt solution or combined with watering every 4 days (the proportion should be carried out in accordance with Chinese drinking water standards), so as to delay the ejection of fungus spores, prevent ear rot, nematode occurrence and mold infection, and increase the thickness and brightness of fungus.

5. Picking

There is a powder layer in the abdomen of the ear piece, which basically unfolds and softens and stops water for one week, which makes the ear root contract. When the ear piece is all unfolded and the diameter is up to 2.5~3cm, it can be collected centrally, and excessive harvesting of the ear piece is prohibited. Harvest should adhere to the large and small, such as the uniform size of the ear piece, can be picked at one time. Stop watering after harvest and continue to spray water after the formation of new ear buds. Generally, 2-3 stubble can be picked in each batch.

The most important thing for planting Auricularia auricula in greenhouse is disinfection in the greenhouse, which can avoid miscellaneous bacteria affecting the survival rate of Auricularia auricula mycelium. The above is about the introduction of planting fungus in greenhouse. I hope it can help you.
