Key points of soil covering techniques for cultivation of Ganoderma lucidum and Tilia amurensis

Linden cultivation of Ganoderma lucidum and then soil mulching can keep moisture, increase yield and increase benefit. In addition to its operation and ordinary cultivation, but also to master the following technical points: first, site selection and treatment to choose near water sources, convenient transportation, sandy soil, flat, leeward pollution-free place. Determine the corresponding width according to the amount of cultivation, preferably in a rectangle. Get rid of the weeds around it, remove the weeds in branches and leaves, plough them into pieces, flatten them, and then press the width of 1 meter to 3.4 meters. The length of the chamber depends on the venue, and the length of the chamber depends on the length of Linden wood. Second, the soil mulching for the cultivation of Ganoderma lucidum requires good permeability, rich in a variety of nutrients needed by Ganoderma lucidum, few miscellaneous bacteria harmful to Ganoderma lucidum, suitable humidity and so on. Sandy loam should be used nearby, or some sawdust should be added to improve permeability. In order to increase nutrition, organic materials such as grain hull and corn stalk powder can be added, and pesticides such as lime and formalin can be used to kill in order to reduce miscellaneous bacteria. In addition, we should also pay attention to ant control, insect control, waterlogging and so on. Third, if the mycelium covered with Linden wood is covered in time, it should be moved into the field in time to cover the soil. In the compartment, the distance between the stick and the stick should be 5 cm ~ 10 cm. The covered soil filled between the bacterial sticks. The thickness of soil cover depends on the water content, moisture retention and environmental conditions of Linden wood. Sometimes let the top of Linden expose 2cm ~ 3cm, sometimes cover the top of Linden ranging from 2cm ~ 3cm. 4. Build a shade shed because the formation and growth of Ganoderma lucidum require higher humidity, so Ganoderma lucidum has to build a shade on top of it. The shed can be covered with a flat shed or an arch shed. The shed is made of bamboo and wood, surrounded by straw, corn stalk, wheat straw and other weeds. The shed is so high that people can go in and do their homework. The two sides of the shed are surrounded strictly, the doors are left at both ends, and electric windows are opened if necessary. If the shed is too wide, a small shed should be built in the greenhouse. The construction of the shed had better be completed a few days before the sesame entered the box, and sterilized and insecticidal. 5. After scientific management and protection of sesame materials into the shed, the air temperature should be kept at 24 ℃ ~ 27 ℃, and the air relative humidity should be 85% and 90%. When leaving Ganoderma lucidum, the temperature of the shed should be kept at 26 ℃ ~ 30 ℃, the humidity should be 88% and 94%, and there should be some scattered light and sufficient oxygen. Ventilated 2 ~ 3 times a day for 20 ~ 30 minutes each time. Spray water should not be sprayed directly on Zhi Lei. Spray water to the cover when the cover is 2cm ~ 3cm. 6. after about 50 ~ 60 days after the formation of the mature harvest, when the edge of the cover is the same as the color of the middle, the cover and handle should be harvested in time. If the harvest is early, the output is low and the quality is poor; if the harvest is late, it may be eaten by insects, and it will also affect the time of the next batch of Zhi. When picking Ganoderma lucidum, the handle should be 2cm ~ 3cm. After harvest, Ganoderma lucidum stopped spraying for 4 ~ 7 days. Then increase the humidity to 85%-94% and keep it at 24 ℃-30 ℃. After 7-10 days, the sesame bud grows again in other parts of the harvested sesame stalk. With the same management as above, it can be harvested in 25 ~ 40 days. Depending on the size of the sesame, 1 ~ 2 batches can be taken in the same year. One or two batches can be collected in the second year. When Ganoderma lucidum is covered with soil, the mycelium can absorb nutrients from the covered soil and moisturize it, so it can increase production by 15% to 25%.
