Planting Ganoderma lucidum wants to harvest three times a year. These five points need attention.

Ganoderma lucidum is a kind of medicinal fungus, and it is also one of the nine immortal herbs in China. With the development of modern medicine, its medicinal value has been continuously explored, so the market demand is increasing day by day, so the cultivation of artificial Ganoderma lucidum has received widespread attention. The following OPE Sports introduces the five key points that Ganoderma lucidum needs to master three times a year. 1. Ganoderma lucidum is a kind of mushroom fungus with high temperature and constant temperature in reasonable cultivation season. In the process of growth and development, higher temperature is required, and the best temperature is 26 ℃ ~ 28 ℃. The optimum temperature for mycelium growth was 28 ℃, which was significantly inhibited when the mycelium growth was lower than 27 ℃, and could be aged and autolyzed when the mycelium was higher than 30 ℃. The optimum temperature for fruiting body growth was 24 ℃ ~ 28 ℃, but it could not grow normally when it was below 18 ℃. Ganoderma lucidum primordium formation and fruiting body growth stage do not need temperature difference stimulation, too large temperature difference, can produce deformed Ganoderma lucidum. Taking this as the control, only the temperature from May to October in Anhui Province can meet the needs of the growth and development of Ganoderma lucidum. From the point of view of three harvests a year, the final harvest time should be in early September, so it is estimated that the mother seed should be propagated in early March, the original seed should be propagated in early April, the cultivation and inoculation should be carried out in early May, and it can be harvested three times in early July, early August and early September. Second, there are many improved varieties of Ganoderma lucidum. According to the shape and color, it can be divided into six kinds: Ganoderma lucidum, Ganoderma lucidum and Ganoderma lucidum. The general cultivated variety is Ganoderma lucidum. In Ganoderma lucidum, the improved varieties are: Xinzhou, Huizhou, South Korea, Taishan No. 1, Dabie Mountain Ganoderma lucidum and so on. Xinzhou Ganoderma lucidum, with strong stress resistance, large and thick bacterial cover, good commodity and high yield, is an excellent variety for export to earn foreign exchange. South Korean Ganoderma lucidum has fast bacteria, early production, large and neat pieces and high yield. Mount Tai Ganoderma lucidum grows rapidly and is suitable for substitute cultivation, but its yield is slightly lower. Ganoderma lucidum in the Dabie Mountains, with a large cover and dark color, is more suitable for wood cultivation. Therefore, all localities should determine the varieties according to the local production conditions (such as substitute material or section wood cultivation) and the purpose of production (such as export or domestic sale). If you adopt substitute cultivation and achieve three harvests a year, you can choose South Korean Ganoderma lucidum. Third, reasonable selection of substitute formula Ganoderma lucidum is woody saprophytic bacteria, suitable tree species are oak, sour jujube, bird tallow, elm, poplar, etc., substitute cultivation should be based on sawdust of suitable tree species, properly matched with some cottonseed shell, corncob, etc., commonly used formula can be selected: 1, miscellaneous wood chips 83%, corn flour (or wheat bran) 15%, gypsum powder 1%, sugar 1%. 2. Cottonseed hull 39%, sawdust 39%, corn meal (or wheat bran) 15%, gypsum powder 1%, sucrose 1%. 3. Corncob 78%. Wheat bran 15%, gypsum 2%, sucrose 1%, superphosphate 1%, urea 0.5%, lime 2.5%. The older the sawdust, the better, but not mildew. Bran can also be replaced with rice bran and gypsum with calcium carbonate. The ratio of material to water is 1.4mm 1.6. 4. Bag sterilization culture mycelium cultivation bag can choose wide 17cm, thick 0.4mm low pressure ethylene or acrylic tube material, cut into 33cm long bag, fasten one end with rubber band (cut into white driving inner tube), mix well according to one of the above formula and put it into the bag. Bagging machines can also be used where conditions permit. When installing, we should strive to achieve the consistency of tension and tightness, and tie it to the other end after installation. When packed to the appropriate number of bags, put into the atmospheric pressure sterilization pot to sterilize. Sterilization time is 10-12 hours, it is best to cook during the day, stew overnight before coming out of the pot. After getting out of the pot, the inoculation can be carried out when the bag temperature drops to about 30 ℃. The bag after inoculation can be put into the culture room for mycelium culture. In the process of cultivating mycelium, when the temperature exceeds 28 ℃ and the humidity exceeds 65%, it should be ventilated to cool down. Attention should be paid to shading and ventilation during mycelium growth. In about 40 days, the mycelium can grow all over the bag. Fifth, strengthen management and timely harvest bags full of mycelium can be transferred to the cultivation room. The bag can be stacked and stacked at a height of 8 to 10 layers. After the fruiting body appears at the mouth of the bag, cut off the rubber band to let it produce mushrooms. During this period of time, we must maintain the appropriate temperature, humidity, light and control ventilation. The indoor temperature should be kept at 26 ℃ ~ 28 ℃, the air relative humidity should be kept at 85%-95%, and the scattered light should be used for illumination. Ganoderma lucidum is very sensitive to carbon dioxide, poor ventilation can produce deformities. It can be harvested when the edge of the cap no longer grows and brown-red spores grow. It is best to cut it with a knife so that a new fruiting body can grow quickly on the original basis. After the second tide is ripe, it will be harvested again and again. Received: after the second tide, you can also take off the bag and bury it in the soil to make up for the lack of moisture in the bag. As long as the temperature is right, you can harvest three times. Under normal circumstances, 100 kg of dry material can be collected three times Ganoderma lucidum 8: 10 kg of Ganoderma lucidum should be dried in time.
