Coprinus comatus bag planting technology

Coprinus comatus Cc168 strain is a new type of strain with high potential for commercial development and development prospect introduced from Japan. Now we will introduce the cultivation points as follows:

(1) 78% straw, rice seed husk 15%, wheat bran 3%, lime 1-2%, gypsum powder 2%, pH value is adjusted to 8 or so, and lime can be used to adjust the pH to a small extent. Bagging and seeding are treated as usual.

2 Test results (b) Seasonal arrangement of coprinus comatus mycelium growth temperature 8 ~ 38 °C, the optimum temperature of 18 ~ 25 °C; fruiting temperature of 12 ~ 28 °C, the optimum temperature of 16 ~ 25 °C, is a high temperature type. When other conditions are the same, the temperature significantly affects the biological conversion of Coprinus comatus. In April and October, biotransformation rates were quite high, at 141% and 152%, respectively, due to the optimum temperature for coprinus comatus growth. The lowest biological efficiency in July and August was only 81%. In order to have a higher yield, the fruiting time is appropriate from September to May.

(3) The construction of Yangshuo in bag cultivation shall be based on high landform, fertile land, convenient drainage, clean water near the water source and the surrounding environment. It shall be 150 centimeters wide, 30 centimeters deep and of unlimited length. Digging well after the irrigating water, to be slightly dry after the bottom of the hole loose, flat, while topdressing compound fertilizer, spraying agents, in order to achieve the purpose of disease prevention and pest control. Bagging and sowing according to the conventional method, about 20-25 days, the mycelium can be filled with bacteria bags, about 10 days after the full bag off the bag, after the bags are arranged vertically in the pit.

(IV) Effects of Oxygen Supply Coprinus comatus is an aerobic saprophytic strain and therefore requires a lot of oxygen during its growth. Practice has shown that the oxygen demand of Coprinus comatus during the entire life cycle is very different. In the mycelial growth phase, the oxygen demand is basically the same as that of the oyster mushroom, but in the growth stage of the fruiting body, it is higher than the oxygen demand of the oyster mushroom. . The proper oxygen content in the air can significantly increase the growth of Coprinus comatus, which is due to the appropriate oxygen to enhance the ability of the hyphae to decompose the culture medium, and the oxygen supply is an important factor in increasing coprinus comatus production.

(5) Proper lighting can promote mycelial growth. Practice has shown that when the light intensity is less than 10 lux, the mycelium grows very slowly, and on average, it delays about 7 to 11 days before the mushroom is released. The fruiting bodies grow very slowly in the absence of light stimulation, and the harvest is delayed by an average of 5 to 9 days, and the biological efficiency is also generally about 100%. When the light is too strong, if it reaches 1500 lux or more, the growth of mycelium or fruit body is slower than 10 lux or less. At this time, the growth of the fruit body is not only slow but also of poor quality, dryness, and pale yellow color. . The ideal light intensity is generally 70-800 lux. The Coprinus comatus that grows in such light is fast, has high yield, good quality, and is insusceptible to bacterial infection during growth, resulting in high commercial value.

(6) Cover soil Since Coprinus comatus has the characteristics that the mycelium does not contact the soil without mushroom, it must be covered with soil. 50% of pasture soil, 40% of river silt, 8% of ash, and 1 to 2% of lime powder are mixed and mixed. Finally, the water is sprayed wet, and the water content is 60 to 70%. As a group, you can disperse it as a limit. Cover soil thickness is generally 3 - 5 cm, soil particle size does not exceed 2 cm in diameter is best. After covering, if the temperature is around 18-25°C, a large number of mycelia will appear in the soil after 10 days, and fruiting bodies will form.

(vii) The cotyledons of Coprinus comatus were grown 7-8 days later and should be harvested when the cap has not been opened. Otherwise, the black spores released after coprinus comatus ripening and opening can cause autolysis of fruiting bodies, which will greatly reduce the commercial value of Coprinus comatus.

After supplementing with nutrient solution, a high-water liquid fertilizer was sprayed 500 times after the flooding of the mushroom, and a 1% compound fertilizer supernatant was sprayed on the soil after the three tide mushrooms. Generally can increase production by 25-35%. A biological cycle can receive 3 - 5 tides, biological efficiency up to 150 ~ 170%.

European Cylinder

Cylinder locks have several standardized profiles, a popular one of which, is the Euro profile. The locks are mainly used on residential doors. They are very easy to remove and install. It can be removed, quite easily, without changing the bolt work. Divided into single unlock core, double unlock core and a side thumbturn Knob Lock core.
