Embodiment 1

[0017] 1) Pre-processing of mulberry wood chips: After the mulberry tree is felled, the trunk and branches are peeled and crushed by a crusher to a particle size of 0.5-1cm, and dried in the sun for later use.

[0018] 2) Ingredients: 37% wood chips, 43% cotton shells, 11% bran, 8% rice flour, 1% gypsum, and the ratio of material to water is 1:1.3—1:1.5.

[0019] 3) Mixing material: First, mix wood chips, cotton shells, bran, rice flour, and gypsum to form a dry material, then add water and mix well to form a culture medium. Drops of water will do.

[0020] 4) Bagging: After the mixing is completed, stack the materials for 1-2 hours, so that the water is fully absorbed by the base material, and then it can be bagged. Choose a 17*35*0.05 polypropylene plastic fruiting bag with about 400 grams of material (dry material). The material should not be too full. Both ends of the material bag should be tied, and the mouth of the bag should be cleaned to prevent contamination by bacte...

Embodiment 2

[0027] In order to select the best cultivation substrate formula, refer to the traditional cultivation application formula, design the following four substrate preparation schemes: ① 73% wood chips, 25% bran, 1% sugar, 1% gypsum, material-water ratio 1:1.5; ②37% ​​wood chips, 36% cottonseed hulls, 25% bran, 1% sugar, 1% gypsum, 1:1.3 ratio of material to water; ③37% wood chips, 43% cottonseed hulls, 11% bran, corn Powder 8%, gypsum 1%, material-water ratio 1:1.4; ④ structure wood chips 58%, cottonseed hulls 30%, bran 10%, sugar 1%, gypsum 1%, material-water ratio 1:1.5.

[0028] After uniform inoculation and culture, the mycelium development status of the four different formula substrates is as follows: Formula ① Mycelium growth is slow in the early stage, there is a significant growth rate in the middle stage, and the stretching is weak in the later stage. The time to fill the bottle is about a week later than the other three formulas. White and strong, but stretch unevenly, m...

Embodiment 3

[0031] For the preferred matrix formula ③ (37% wood chips, 43% cottonseed hulls, 11% bran, 8% corn flour, 1% gypsum, material-to-water ratio 1:1.4), the sesame-leaving test was carried out. Compared with poplar wood chips, the main material of conventional Ganoderma lucidum cultivation, poplar wood chips accounted for 37%, and other auxiliary materials and addition ratios were the same as formula ③. The results of the comparison test are as follows: the mycelia cultured on the matrix containing ganache wood chips are stronger than those cultured from poplar wood chips, but the stretching speed is not as good as the latter, and the growth of lucidum is slightly later; The fruiting body of Ganoderma lucidum cultivated with wood chip substrate has regular appearance and bright color, thick cap, the yield is 18.12% higher than that of poplar sawdust, and the polysaccharide content of Ganoderma lucidum is 9.82% higher than that of poplar sawdust.

[0032] The above-mentioned formul...

Abstract

The invention belongs to the field of edible fungi cultivation, and relates to a lucid ganoderma substitute cultivation medium using paper mulberry wood saw dust as a main material, and the formula comprises the following dry substances by weight percent: 37-73% of paper mulberry saw dust, 25-62% of auxiliary material selected from one or more of cottonseed hull, bran and corn powder and 1% of additive gypsum, as well as 1% of optional sugar according to the formula demand; the material-water ratio is 1:(1.3-1.5). The lucid ganoderma substitute cultivation medium is sued for cultivating lucid ganoderma, the cultivation period is moderate, and the yield and quality of the lucid ganoderma are obviously improved in comparison with those of conventional poplar saw dust; in comparison with traditional poplar saw dust cultivation, the yield per unit of the lucid ganoderma in the paper mulberry wood saw dust cultivation is improved by 18.12%, and the polysaccharide content of the lucid ganoderma is improved by 9.82%. As wild resource with abundant value, the utilization mode of the paper mulberry can be further broadened for lucid ganoderma cultivation, and the paper mulberry has popularization value on the aspects of protecting environment, utilizing wild resource utilization, increasing rural income, remitting fungi-forest confliction and the like.

Description

technical field [0001] The patent belongs to the field of edible fungus cultivation, and is a ganoderma lucidum substitute cultivation substrate mainly made of wood chips. Background technique [0002] Ganoderma lucidum, also known as Ganoderma lucidum grass, fairy grass, etc., is the whole plant of Chizhi or Zizhi of Polyporaceae. As a traditional Chinese medicinal material with a history of thousands of years of medicinal use, it has high medicinal value. After decades of modern pharmacological research by scientific research institutions, it has been confirmed that Ganoderma lucidum can enhance human immunity, regulate blood sugar, control blood pressure, and assist tumors. Radiotherapy and chemotherapy, liver protection and liver protection, sleep promotion and other aspects have significant curative effects. Ganoderma lucidum polysaccharide is one of the main active ingredients of Ganoderma lucidum medicinal function, which has anti-tumor, immune regulation, hypoglycem...
