Three points to note in planting Ganoderma lucidum: these five points must be remembered

Ganoderma lucidum is an important fungus, one of the nine immortal herbs, which has been widely concerned. Therefore, many growers have begun to artificially cultivate Ganoderma lucidum. Let's take a look at the precautions for planting Ganoderma lucidum three times a year.

1. Reasonable cultivation season

Ganoderma lucidum is a kind of mushroom fungus with high temperature and constant temperature. In the process of growth and development, it requires higher temperature, and the best temperature is 26℃~28℃. The optimum temperature for mycelial growth was 28℃, growth was inhibited obviously below 27℃, and senescence and autolysis occurred above 30℃. The optimum temperature for fruit body growth is 24℃~28℃, and it cannot grow normally below 18℃. Ganoderma lucidum primordium formation and fruiting body growth stage do not need temperature stimulation, temperature difference is too large, can produce abnormal Ganoderma lucidum. As a contrast, in Anhui Province, only the temperature from May to October can meet the needs of Ganoderma lucidum growth and development. Considering from the angle of three harvests a year, the last harvest period should be in the first ten days of September. Based on this calculation, the mother seed should be propagated in the first ten days of March, the original seed should be propagated in the first ten days of April, the cultivation and inoculation should be carried out in the first ten days of May, and three harvests can be carried out in the first ten days of July, the first ten days of August and the first ten days of September.

II. Selection of improved varieties

There are many kinds of Ganoderma lucidum. According to its shape and color, it can be divided into six kinds: red ganoderma lucidum, black ganoderma lucidum, green ganoderma lucidum, white ganoderma lucidum, yellow ganoderma lucidum and purple ganoderma lucidum. The common cultivated variety is red ganoderma. In Chizhi, fine varieties include: Xinzhou, Huizhou, South Korea, Taishan No. 1, Dabie Mountain Ganoderma lucidum, etc. Ganoderma lucidum Xinzhou, strong resistance, large and thick cap, good commodity quality, high yield, is an excellent variety for export. South Korea Ganoderma lucidum, rapid development of bacteria, early production of Ganoderma lucidum, large and orderly, high yield. Mount Tai Ganoderma lucidum grows rapidly and is suitable for substitute cultivation, but its yield is slightly lower. Dabieshan ganoderma lucidum, cover big color deep, it is more suitable for cultivation of logs. Therefore, each place should determine the variety according to the local production conditions (such as whether it is a substitute or a log cultivation) and the purpose of production (such as export or domestic sales). To achieve three harvests a year, South Korea Ganoderma lucidum can be selected.

III. Reasonable selection of substitute formula

Ganoderma lucidum is a woody saprotic fungus. Suitable tree species include oak tree, jujube tree, tallow tree, elm tree, poplar tree, etc. Substitution cultivation should be based on sawdust of suitable tree species, properly matched with some cottonseed hull, corn cob, etc. Common formulas can be selected:

1. Mixed sawdust 83%, corn flour (or wheat bran)15%, gypsum powder 1%, sucrose 1%.

2. Cottonseed hull 39%, miscellaneous sawdust 39%, corn flour (or wheat bran)15%, gypsum powder 1%, sucrose 1%.

3. Corncob 78%. bran 15%, gypsum 2%, sucrose 1%, calcium superphosphate 1%, urea 0.5%, lime 2.5%.

The more old the sawdust, the better, but not mildew, bran can also be replaced with rice bran, gypsum with calcium carbonate instead. The ratio of material to water is generally 1:1.4~1.6.

4. Bagging sterilization culture hyphae

The cultivation bag can be selected from low pressure ethylene or propylene tube material with width of 17cm and thickness of 0.4 mm, cut into 33cm long bags, tied with rubber band (cut into white inner tube), and mixed according to one of the above formulas. Conditions can also be used where bagging machine bagging. When installing, we should strive to achieve the same tightness, and tie the other end after installation. When filled to the appropriate number of bags, put into the atmospheric sterilization pot sterilization. Sterilization time is 10~12 hours, preferably burning in the day, stewing overnight and then out of the pot. When the bag temperature drops to about 30℃, inoculation can be carried out.

The inoculated bags can be put into the culture room for mycelium culture. When the temperature exceeds 28℃ and the humidity exceeds 65%, ventilation should be conducted to cool down the mycelium. During hypha growth, attention should be paid to shading and ventilation. After about 40 days, the bag can be filled with hyphae.

V. Strengthening Management and Timely Harvest

The bag full of hyphae can be transferred into the cultivation room. The bags can be stacked, and the stacking height is 8~10 layers. Cut off the rubber band after the fruiting body appears at the mouth of the bag so that the fruiting body can be produced. During this time, it is necessary to maintain appropriate temperature, humidity, light and control ventilation. The indoor temperature should be kept at 26℃~28℃, the relative humidity of the air 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 deformity. When the edge of the cap no longer grows and brownish red spores grow, they can be harvested. It is best to cut with a knife when harvesting, so that new fruit bodies can grow quickly on the basis of the original. The second tide matures and then re-grows and re-grows. After harvest: After two tides, you can also take off the bag and bury it in the soil to make up for the lack of water 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, 8~10 kg of Ganoderma lucidum should be dried in time.
