At this stage, high-tech is very developed, everyone knows that cordyceps is a big supplement Chinese herbal medicine, natural cordyceps simply can not meet the requirements of the people, artificial cultivation is a good new project, about artificial cultivation technology is poor, below to many cordyceps planting staff to give a technical point, the key goal is first, Plant cordyceps staff from the glass bottle manufacturers to buy home, to pay attention to matters after adequate disinfection.
1. Cordyceps sinensis mycelium culture: mycelium culture based on rice 69%, corn grits 27%. Add 3% of the ingredients (peptone. Silkworm chrysalis powder. Vitamins. Mannitol), water content 68%, PH 5.2 ~ 7.6. Cordyceps bottle for cultivation supplies, culture material depth of 2.8 cm, then sealed with polypropylene film. Immediately into the pressure cooker sterilization, natural pressure sterilization at 100 ° C for 11 to 15 hours, autoclaving under 2.6KG/ cubic centimeter working pressure for 1.8 hours, after sterilization, the rice in the bottle should be left and right wet area contradiction. When the bottle material temperature drops below 32℃, the mother seed is connected in the sterile test box and cultivated under the black stain cleaning standard. The relative humidity of the air in the cultivation room persists at 65%, the temperature is about 18.5℃, and the mycelium can climb the cultivation base in 18 to 22 days and enter the division period of the fruiting body.
2. Substratum cultivation and management method: The light can be increased after the mycelium is full of Cordyceps Aquarius, and the mycelium changes from milky white to orange-yellow or orange-red after 27 to 32 days of light. After the mycelium metabolizes melanin, the surface of the cultivation material will show granular orange-yellow fungus buds. The key to the color management method is lighting, the use of sunlight during the day, morning and evening with fluorescent lamps to enhance the light, when the material becomes yellow, you can interrupt the light effect against the background.
When there is a primitive in the bottle, natural ventilation begins, and the temperature control in the room is 21.5 ~ 23.5℃, which is convenient for the composition of the fruiting body. The relative humidity of the air should reach 85% at the time of budding, and the ambient humidity should expand to 92% ~ 98% when the fruiting body grows to 1.2 cm, so as to reduce the distribution of water in the material. With the growth and development of fruit bodies, the laminated glass cordyceps bottle requires gas and persistent water, and the method of needling holes in the bottle stopper membrane can be used to persist in indoor ventilation.
3. Picking production and processing: from the composition of the primary base to the completion of the fruiting body requires 22 to 33 days, when the surface of the fruiting body shows light yellow granular powder, mark the completion of the fruiting body, you can pick. After picking, immediately dry and treat, and after slightly anti-tide, bind into several bundles with thread and put them into packing bags for sealed storage.
