Cultivation Technology of Coprinus comatus

1. Clinker cultivation

The production of cultivated bacteria stick is the same as that of cultivated species. Put the cultivated bacteria bag into the border horizontally or vertically after removing the bag, the interval between the bacteria rods is 2mur3cm, fill it with fertile soil, discharge 30 bacteria sticks per square meter, after discharge, cover the soil for about 3cm. If the soil is too dry, spray water slightly and cover it with polyethylene plastic film that has been soaked in 5% Lysol solution.

Researchers in Jiangsu Province have done comparative experiments on horizontal or vertical arrangement of bacterial sticks, which shows that vertical arrangement of mushrooms is faster and has higher biological efficiency. Soil covering should be carried out in two steps: first fill the soil between the fungus sticks, pour through the water, and then cover the surface of the fungus sticks with fine soil about 3 cm thick. Water with spray to avoid soil hardening and facilitate mushroom production. Cover the soil with a thickness of 0.5 ml 1 cm, not more than 2 cm. Keep the relative humidity of the air in the cultivation room at 85% Mui 90%, and adjust the temperature to 16 Mel 22 ℃. There should be shading measures outside or in the greenhouse to avoid strong light. A week later, the mycelium returned to growth and connected into blocks, and the plastic film was sprayed with water every day, while increasing ventilation to stimulate mycelium knots and form mushroom buds. After breaking the soil, the mushroom bud is mainly ventilated and humidified in management. After more than 10 days of careful management, the fruit body grew rapidly, about medium well, that is, it should be harvested in time.

Second, uncooked material cultivation

The cultivation of Coprinus comatus with raw meal is more practical than that with clinker. Practice has proved that both the north and the south can be popularized.

1. Preparation of culture materials

① cottonseed hull or ground waste cotton 100kg, quicklime 2Mel 3kg (some add 0.1% carbendazim or methyl thiophanate), water content 60% Mel 65%.

② cottonseed hull 100kg, phosphate fertilizer 2kg, urea 0.5kg, lime 2kg, water 160kg.

③ corncob (crushed) 100kg, urea 1kg, lime 2kg, water 150ml 160kg.

④ rice straw (sliced or crushed) 40kg, corn straw powder 40kg, horse manure (dry manure and broken) 20kg, urea 1kg, phosphate fertilizer 2kg, lime 3kg, water 150kg.

⑤ Flammulina velutipes mushroom bran 80kg, cattle and horse manure 20kg, urea 1kg, phosphate fertilizer 2kg, lime 4kg, water 150kg.

2. Cultivation and management

Mix the culture material well. The accumulated material is 1 meter high, 1.2 meters wide and 1.5 meters wide, with unlimited length. Cover with plastic film for heat preservation, keep it at 60 ℃ 70 ℃ for 10 hours, then turn over. When the temperature reaches 60 ℃, keep it for another 10 hours, the fermentation is over. Spread cool and spread on the pre-prepared border surface, the material thickness is 10mur20cm, sow in three layers, and the seed amount is 15% of the culture material. After sowing, flatten the material surface, compact it slightly, and finally cover the loam with a thickness of 5 centimeters or cover with plastic film to keep warm and moisturizing. After the mycelium has grown, remove the plastic film and cover the soil, first cover the coarse soil (pre-wet with lime water in advance, the soil thickness is 0.8 / 1.2 cm), then cover the fine soil and spray water to moisturize.

When cultivated in the open air, after covering the soil, the border should also be protected by an arched plastic shed, which is 30m high and 40cm high.

Outdoor cultivation in the south should pay attention to the changes of air temperature, rainfall and wind from sowing in September to the end of harvest in May of the following year. For heat preservation and moisture preservation in North China, it is suitable to be cultivated in plastic greenhouse, which can be produced all the year round except during the hot summer period.

The yield of Coprinus comatus varies greatly due to different strains, culture materials and cultivation conditions, with an output of 4.5 kilograms per square meter, with a biological efficiency of 20%, 70% and more than 100%.
