Summer tube technology of Duanmu Ganoderma lucidum

First, Ganoderma lucidum: mature fungi begin to form primordia about 10 seconds after covering the soil, because the light in the artificial shade is generally strong. The cross section of fungus is easy to form more primordia when stimulated by light. In order to improve the quality of Ganoderma lucidum, the excess primordium should be removed. There are only two sturdy primordia left in each section of fungus. If two primordia are left, the distance should be more than 15 cm. Otherwise, the cap will stick together due to crowding after differentiation, resulting in deformities and reducing the value of the commodity. Ganoderma lucidum can be removed directly by hand and covered with fine soil in the original part to avoid the formation of primordia again to consume nutrients.

Second, waterlogging prevention: after the wood is decomposed by mycelium, the wood is soft and loose and has strong water absorption capacity. If the field cannot be drained in time after the rainstorm, the water content of the fungus is too heavy, and the wooden pores are blocked, which hinders the transport of nutrients to the mycelium. The fruiting body will stop growing or even die. To this end, in addition to paying attention to dredging the drainage ditch at ordinary times, the film should be arched in time when it rains to strictly prevent the border surface from being drenched and soaked. For the fungus soaked in water, it is necessary to dig out the fungus in a cool sun for 5 days, and when the moisture content of the fungus is less than 35%, it can still produce Ganoderma lucidum normally.

Third, ventilation: the sesame field should be both ventilated and moisturized, and ventilation is the first condition to prevent the breeding of all kinds of bacteria and insect pests. To this end, in addition to the north and south doors of the shade shed, it is also necessary to open additional floor windows in the form of opposite ground windows, so that Ganoderma lucidum can grow smoothly under the condition of ventilation and alternation of dry and wet.

Fourth, light: Ganoderma lucidum stalk length, dim color and light, and the light intensity of the shade shed is closely related. The test showed that the transmittance was more than 40%, the stalk was only 2mi 3cm long, even nearly without stalk, and the cap was rough and dull. While the transmittance is less than 20%, the stalk can grow to 8 mi 12 cm, and the cap is bright and close to the wild. Therefore, the shade shed is best covered with ferns. If there are conditions around the sprouting shed and the central position, it is best to plant twining plants such as pumpkins or peas. When the high temperature season comes, the branches and leaves of melon and bean vines can effectively reduce the temperature and light of the sesame field and protect Ganoderma lucidum from extreme heat.

Fifth, timely harvest: with the improvement of people's consumption level, Heizhi has mostly turned to food in high-consumption areas. The delicious taste of thin-edged Zhi than thick-edged Zhi has been recognized by diners that the maturity is less than 70%. For this reason, growers should take the market as the guide and grasp the harvest time flexibly in order to obtain the best economic benefits. After harvest, the sesame bed should be pine in time, and the air humidity in the field should be adjusted above 85%, so as to facilitate the smooth occurrence of the second batch of Zhi.
