How to grow Coprinus comatus cultivation techniques

Coprinus comatus is a kind of mushroom, which is very popular with consumers in the market at present, and the sales volume is very good. So a lot of people have the idea of growing it. Coprinus comatus needs to do a lot of work in planting, so let's take a look at it.

How to grow Coprinus comatus

1. Selection and ingredient. The cultivation site can be intercropped in indoor or outdoor fields, greenhouses, or between fruit trees and crops. Planting season all year round, summer in indoor or shade shed planting, autumn, winter and spring are mainly outdoor, open-field cultivation. Ingredients: according to the planting area of 20 square meters, 400 kg of dry straw and 20 kg of lime powder are needed. In addition, auxiliary materials (such as wheat husk, rice bran) can be added appropriately.

2. Raw material treatment. Pour 3% lime water on the ingredients, while watering while stacking the culture material, the heap is 2 meters high, the length and width are self-defined, and the film is fermented after strict patting. Insert a thermometer in the material, when the material temperature rises to 60 ℃, continue to turn the pile once the next morning, turn while pouring 3% lime water, cover the film again as before, and maintain it for 1 day when it reaches more than 60 ℃.

3. Fermentation bag cultivation. Generally choose the size of the plastic bag is 22 cm × 45 cm, 24 cm × 48 cm, 26 cm × 50 cm, the thickness is 0.015 cm. Wash the mycelium-growing strain bag on the outside, cut through the plastic bag, and divide the strain into peanut kernels in a clean box. Bacteria can not be released into the tuyere and the sun, it should be used up on the same day. The bacterial bag is divided into 3 to 5 stacks, and 3 rows of small holes are pierced equidistant from the thick needle of the sewing machine. The position of the hole is better facing the bacteria in the bag, which is easy to breathe and promote the mycelium to germinate and grow fast.

Cultivation techniques of Coprinus comatus

1. Build a bed: Coprinus comatus builds a bed according to the direction of the mushroom shed, with an interval of 0.5 meters. Dig a mushroom bed with a width of 80 cm, 100 cm and a depth of 15 cm in the greenhouse, with unlimited length. Pour through the bottom water and sprinkle 150 grams of lime powder on each square meter of border.

2. Sowing: the layer sowing method can be used for sowing, generally 3 layers of material and 3 layers of species, the thickness of the material is 15-20 cm, and the sowing rate is 15-20%. First spread a layer of 5 cm thick culture material in the mushroom bed, and then sprinkle 1 layer of bacteria, so that a total of 3 layers of material, sprinkle 3 layers of seeds. After sowing, cover sterilized plastic film and newspapers for germicidal management.

3. Germ: insert a thermometer into the material about 10 cm deep through the plastic film to observe the material temperature change. From the fourth day of inoculation, lift the film cover once a day to make it ventilated. Note that the material temperature of 10 cm should not exceed 25 ℃, and it is best to keep it below 25 ℃. When the material temperature is on the high side, it can strengthen the ventilation in the shed at night and under the plastic film, and can also open the newspaper and spray an appropriate amount of water to cool down. The hyphae of Coprinus comatus can be covered with material layer in about 20 days.

Management of mycelium fermentation stage

1. Accumulation fermentation. When the temperature is 10 ℃ ~ 20 ℃, 3 ~ 4 layers are stacked, and 1 ~ 2 layers are stacked when the temperature is 20 ℃ ~ 25 ℃. When the temperature is above 25 ℃, the single layer is discharged.

2. Temperature. The hyphae of Coprinus comatus can grow at 8 ℃ ~ 30 ℃, and the suitable temperature is 20 ℃ ~ 26 ℃. When the outdoor temperature is higher than 30 ℃, ventilation should be done as early and late as possible. The low temperature season can make the number of accumulated layers of bacterial materials higher, produce accumulated temperature, and promote the growth of hyphae as soon as possible.

3. Humidity. During the mycelial growth of Coprinus comatus, the relative humidity of the air is kept at 60%-70%. During the mycelial growth stage, lime can be sprinkled on the ground to keep dry.

4. Light. Weak light is better, sunlight can not directly shine on the bacterial bag, generally after 25-30 days, the hyphae can grow all over the bag.

Harvesting and processing of Coprinus comatus

1. Harvest: when the mushroom body is strong, the fungus cap has a few scales and wraps the fungus stalk tightly, the fungus ring is just beginning to loose, and it should be harvested when it is about seven minutes mature. If the fruit body is not harvested in time, the fruit body will dissolve and turn black. Do not spray water within 4 hours before harvest to avoid discoloration of the mushroom body. Hold the lower part of the fungal stalk in hand during harvest and gently rotate and pull it out.

2. Processing: fresh mushrooms after harvest should be put into plastic or wooden containers. After cleaning up the soil and sundries of mushroom feet, they will be primary products, and then they will be graded, fresh sold or processed according to the goods. After picking mushrooms, clean up the sundries on the material surface, level the holes in the mushroom picking place, spray 2% lime water, then cover the film, and then carry out mushroom production management according to the conventional method after raising bacteria for 5 to 7 days, generally receiving 3-4 tide mushrooms.

In the initial stage of planting Coprinus comatus, we must do a good job in site selection, and then the proportion of fertilizer is also very important, and then timely cultivation. It is necessary to control the temperature during cultivation in order to ensure its good growth. Later processing and harvesting work is also very important, as introduced above, you can take a look at it more.
