Ganoderma lucidum bag cultivation

Artificial cultivation of Ganoderma lucidum is picked in time, and its effective ingredients can be well preserved. The cultivation technology of artificial bag material is introduced as follows:

First, the cultivation season usually produces bacterial bags in March, begins to bury Ganoderma lucidum at the end of April, can pick the first crop of Ganoderma lucidum at the end of May, and ends cultivation for the whole year by the end of September.

Second, the mycelium of Ganoderma lucidum prepared with culture material should not be produced on a single raw material, but should be combined with a certain amount of nitrogen fertilizer and enough carbohydrates to make it grow vigorously. The hard waste material can be used as raw material after being crushed according to the local resources. The general formula is 78% coarse sawdust, 20% wheat bran, 1% gypsum and 1% sucrose, plus 1% calcium superphosphate and 0.2% urea. Mix sawdust, wheat bran, gypsum and calcium superphosphate again and again, then put urea and sucrose in water and mix in. The appropriate PH value is 6.5 to 7.5.

Third, bagged sterilization and inoculation use low-pressure polyethylene bags or polypropylene bags with a length of 33 to 40 cm, a circumference of 17 to 20 cm and a thickness of 0.05 silk. Each bag contains 40 to 45 grams of dry material, which is required to be loose and tight. After the bag is packed, it can be put into the pot and sterilized. Keep the temperature at 100 ℃ for 10 to 12 hours, then leave the pot for another 4 to 6 hours, and inoculate in the inoculation box when the bag temperature drops below 30 ℃.

Fourth, indoor bacteria management will clean the culture room and spray the walls and floors with 0.3% potassium permanganate or 3% raw lime water. Fumigate and disinfect 0.5 kg of sulfur 12 hours before the bag is moved in, and then place the inoculated bag. The indoor temperature is controlled between 22 ℃ and 30 ℃ and the humidity is between 45% and 55%, preventing excessive temperature from causing pollution or mycelium aging and affecting the formation of fruiting bodies. Untie the tie rope when the two hyphae are almost together in the bag to promote the formation of mushroom buds. When the hyphae meet, they can take off the bag and bury the soil. In the process of cultivation, attention should be paid to insect pests and rodents, and pollution sources should be cut off. The total bacterial cycle is about 25 days.

Fifth, make a border bag according to the size of the plastic shed to make a border with a width of 1 meter, a depth of 30 centimeters and any length, and then spray it with 3% to 5% raw lime water to prevent termites and miscellaneous bacteria. Unbagged mycelia cover 2 to 4 cm of soil, this process must be careful not to damage the primordium. The soil can be covered with peat 70%, river sand 30%, plus calcium carbonate 2%, and adjusted with lime to PH6.5, water content 75%. The covered soil should have strong air permeability and good water absorption.

6. after soil mulching and collecting Ganoderma lucidum mycelium into the shed, straw curtain should be used for shading growth. Pay attention to ventilation to keep a slightly wet environment in the greenhouse all the time. After 4 to 7 days, the original base can grow out of the ground and form a button-sized round Ganoderma lucidum. Ganoderma lucidum grows fast, about 0.5 cm long and wide every day, and can be picked 20 days later when it turns yellow. Start spraying water on the third day after picking, keep the material surface moist, and the second crop of Ganoderma lucidum can grow a month later.
