Cultivation experience of Ganoderma lucidum bonsai in greenhouse

Ganoderma lucidum bonsai is a kind of stereotyped handicraft made from mature dried Ganoderma lucidum in recent years. The Ganoderma lucidum bonsai, which is in the growing stage, can be made into living Ganoderma lucidum bonsai by using foam plastic greenhouse technology. like potted flowers, Ganoderma lucidum seedling stalk elongation, seedling cover expansion, growth, spore powder can be seen, and finally grow into a series of growth and development processes, such as different shapes of Ganoderma lucidum fruiting body. The key points of cultivation techniques are as follows:

1 cultivation substrate

Ganoderma lucidum belongs to wood-rot fungi and is suitable for growing on substrates such as sawdust and cottonseed hulls. The culture medium is composed of 78% sawdust or cottonseed hull, 20% wheat bran, 1% gypsum powder, 1% sugar, and 60% moisture 62% natural pH.

2 cultivation season

Ganoderma lucidum belongs to constant temperature, medium and high temperature fungi, and the seedling temperature and temperature of Ganoderma lucidum are both 22 ℃ and 28 min. Therefore, it is better to produce Ganoderma lucidum in late spring and early summer in southern China. It can be inoculated after mid-January, start to produce Ganoderma lucidum after mid-March, and go on the pot for sale in mid-April. Ganoderma lucidum can be inoculated in early August, in mid-September, and ready for sale in late September. This is conducive to the two golden cycles of the market.

(3) greenhouse construction

The greenhouse is rebuilt from an ordinary plastic greenhouse. The outer layer is covered with sunshade net to achieve the light intensity of seven yin and three yang; the middle layer is 0.5 cm thick foam plastic plate, which has the effect of heat preservation; the inner layer is non-toxic plastic film, which can enhance the moisturizing ability. Both wooden bar frame doors are sealed with plastic film in order to adjust the amount of ventilation and light transmission.

4 selection of varieties

According to the different characteristics of different varieties of Ganoderma lucidum, different types and colors of Ganoderma lucidum can be selected to make live Ganoderma lucidum. It is generally required that the varieties with more branches, longer stalk, small cover, slow growth and few spores are better. For example, Yuanzhi 6, Yuanzhi 9, Peking University, Xinzhou, Zizhi and so on.

5 vaccination in bags

The culture material was prepared according to the above formula, and then filled with 17 × 33 × 0.04 cm polypropylene or polyethylene plastic instead of 400 grams of dry material, sealed with sponge double rings, sterilized under high pressure for 2 hours, sterilized under normal pressure for 10 hours, and moved into the inoculation room after cooling. Ultraviolet and aerosol disinfectants were used for disinfection respectively, and inoculated in the inoculation box.

6 germ culture

After inoculation, move it into the culture room, put it on the culture rack, shade, keep warm, and send bacteria. To maintain the indoor temperature of 20 ℃ 25 min, the electric stove should be heated properly when the temperature is low, and ventilation should be maintained. In about 2 months, the Miao silk will be full of bags.

7 out of Zhi management

After the mycelium grows in the bag, it can be moved to the foam greenhouse for management. Remove the sponge cover, discharge vertically, and cover the plastic film to promote buds. 3After 6 days, Ganoderma lucidum began to bud, that is, lift the covering film, spray water to the ground, keep the relative humidity of the air in the shed at 85%, and try to ventilate at this time. When the stalk of Ganoderma lucidum is elongated and has phototaxis, the door should be shaded, and the roof should be kept transparent to make Ganoderma lucidum grow upward. When the stalk grows to a certain extent, ventilate for half an hour every morning and evening, and remove the shade from the door to promote the growth of the bacterial cover, using the temperature difference between day and night to produce different shapes of sesame.

8 transplanting into the pot

About 20 days after budding, when the cover has grown to the size of the prototype of bonsai, and the edge of the cover is still yellow and white, it can be transplanted into the pot. Cut off the lower part of the Ganoderma lucidum bag with a knife ring, then put it into a flowerpot, add sterilized fine river sand, and become a potted live Ganoderma lucidum.

9 potted plant management

During the continued growth of potted live Ganoderma lucidum, spray 2Mel moisturizing 3 times a day to keep the cap moist so as to avoid premature ripening.
