Problems solved by technology

The artificial cultivation of Poria cocos is mainly based on pine segment wood cultivation, which consumes a large amount of pine wood resources every year. However, under the implementation of the country's strict "natural forest logging ban", Poria cocos has shown a downward trend in terms of single output and total output. Now facing the strict control of pine wood, the Poria cocos industry is facing a serious problem of insufficient pine log resources for cultivation.

Embodiment 1

[0034] A method for cultivating poria cocos in bags, adding water to adjust the moisture content to 60% by adding 76% of pine branches and pine needles, 12% of rice bran, 8.5% of wild rice leaves, 1% of sucrose, 1% of gypsum, 0.5% of magnesium sulfate, and 1% of superphosphate. Mix and stir evenly, pack into bags, add wooden segments at the bottom, and sterilize under high temperature and high pressure to make Poria cocos cultivation bag material. Inoculate Poria cocos strains, culture at 25-30°C for about 30 days, wrap the cellar when the mycelium is overgrown with bacteria, inoculate Poria cocos sclerotia to the wood section and cover sandy soil, the formation rate reaches 98%, and when harvested in 7 months, Poria cocos biological The conversion rate was 43%. Poria cocos polysaccharide content reaches 72%, total triterpene content reaches 0.72%.

Embodiment 2

[0036] A method for cultivating poria cocos in bag materials, adding water to adjust the moisture content to 60% by adding 82.6% of pine branches and pine needles, 13% of rice skin, 1% of sucrose, 1% of gypsum, 0.4% of magnesium sulfate, and 2% of superphosphate, and mixing and stirring evenly , bagged and added 6cm pine wood section at the bottom, and sterilized under high temperature and high pressure to make Poria cocos cultivation bag material. Inoculate the strains of Poria cocos, culture at 25-30°C for about 30 days, wait until the mycelium is overgrown, wrap the cellar, inoculate the sclerotia of Poria cocos to the wood section and cover the sandy soil, the formation rate reaches 99%, and when harvested in 7 months, Poria cocos biological The conversion rate reached 46%. Poria cocos polysaccharide content reaches 73%, total triterpene content reaches 0.73%.

Embodiment 3

[0038] A method for cultivating poria cocos in bag materials, adding water to adjust the moisture content to 60% by adding 82% of pine needles and pine branches, 14.5% of bran, 1% of sucrose, 1% of gypsum, 0.5% of magnesium sulfate, and 1% of superphosphate, and mixing and stirring evenly , bagged and added with wooden sections at the bottom, and sterilized under high temperature and high pressure to make Poria cocos cultivation bag material. Inoculate the strains of Poria cocos, culture at 25-30°C for about 30 days, wait until the mycelium is overgrown, wrap the cellar, inoculate the sclerotia of Poria cocos to the wood section and cover the sandy soil, the formation rate reaches 99%, and when harvested in 7 months, Poria cocos biological The conversion rate reached 48%. Poria cocos polysaccharide content reaches 74%, total triterpene content reaches 0.75%.

Abstract

The invention discloses a poria cocos bag material cultivation medium and a poria cocos bag material cultivation method. The poria cocos bag material cultivation medium comprises the following materials in percentage by mass: 65% to 83.5% of pine needles and pine twigs; 10% to 30% of an organic nitrogen source; 1% to 2% of sucrose; 1% to 2% of gypsum; 0.1% to 0.5% of magnesium sulfate; and 1% to 2% of calcium superphosphate. According to the poria cocos bag material cultivation medium and the poria cocos bag material cultivation method, the poria cocos bag material cultivation medium in which other auxiliary materials are added into the pine needles and pine twigs is researched and developed, the poria cocos bag material cultivation medium is used for inoculating poria cocos strains, and obtained pachymaran and total triterpenes are higher than those of cut-log culture.

Description

technical field [0001] The invention belongs to the technical field of cultivation of edible and medicinal fungi, and in particular relates to a poria cocos bag material cultivation substrate and a poria cocos bag material cultivation method. Background technique [0002] Poria cocos (Schw) Wolf, also known as Yunling, Pine Poria, and Songyu, belongs to the facultative parasite of Polyporaceae, and is an aerobic and dry-loving saprophytic fungus that parasitizes on the roots of pine trees. As a large traditional Chinese medicine, Poria cocos has the effects of diuresis, diuresis, stomach and spleen, and calming the mind. As a homologous species of medicine and food, Poria cocos is not only used in medicinal research and development, but also in food, health care, beauty and other fields. [0003] Poria cocos is a typical wood-rot facultative parasitic fungus. Its hyphae can not only invade living tree roots, but also absorb nutrients from dead trees to survive. It often par...
