Problems solved by technology

[0004] (1) The existing medium formula is not suitable, and it fails to provide all the nutrients necessary for mycelial growth and fruiting body development; (2) The mushroom bud formation period is not concentrated, thus consuming part of the nutrients in the mushroom bag, which indirectly affects the fruiting body (3) Mycelia did not go through a sufficient after-ripening process before forming mushroom buds, and the accumulated nutrients were not enough to form high-yield fruiting bodies; (4) The traditional bag planting method could not artificially supplement the growth and development of fruiting bodies. nutrients

Embodiment 1

[0021] Embodiment 1 Pleurotus eryngii high-yield cultivation method of the present invention

[0022] (1) Culture material preparation

[0023] Preparation of medium A (ingredients, mixing materials, bagging, sterilization): ① Weigh 46.0% cottonseed hulls, 31.9% bagasse, 10.0% peat soil, 10.0% eucalyptus sawdust, 1.0% gypsum powder, superphosphoric acid Calcium 1.0%, trehalose 1.0%; ② Mix cottonseed hulls, bagasse, peat soil, eucalyptus sawdust, and gypsum powder together; ③ Dissolve calcium superphosphate and trehalose in an appropriate amount of water; ④ Combine the two mixtures of ② and ③, and add water to the mixed culture medium. The ratio of mixture to water is 1:1.65.

[0024] Preparation of nutrient soil A (ingredients, mixing materials): 1. Weigh 54.0% of loess, 23.0% of peat soil, 10.0% of coconut peat, 10.0% of pottery gravel (diameter 1cm), 1.0% of superphosphate, and 2.0% of lime by mass; ② Mix the ingredients in ① except superphosphate; ③ Dissolve superphosphat...

Embodiment 2

[0040] Embodiment 2 Traditional cultivation method and mycelia growth of the present invention, fruiting character comparison test

[0041] (1) When the traditional culture medium and the culture medium A of the present invention adopt the traditional fruiting mode, the mushroom bag mycelium growth and output situation (results are shown in Table 1)

[0042]Traditional fruiting bag medium formula 1 (denoted as biography 1): cottonseed hull 98.0%, gypsum powder 1.0%, superphosphate 1.0%;

[0043] Traditional fruiting bag medium formula 2 (denoted as biography 2): cottonseed hull 70.0%, bagasse 28.0%, gypsum powder 1.0%, superphosphate 1.0%;

[0044] The formula of the fruiting bag culture medium of the present invention (recorded as book): 46% of cottonseed hulls, 31.9% of bagasse, 10.0% of marl, 10.0% of eucalyptus sawdust, 1.0% of gypsum powder, 1.0% of superphosphate, and 0.10% of trehalose .

[0045] With reference to Example 1, the fruiting bag medium is prepared, and ba...

Abstract

The invention discloses a high-yield cultivation method for pleurotus eryngii. The method comprises the steps of stripping the plastic bag of a fungus bag overgrown with hypha, so as to promote complete postripeness of the hypha, then accelerating the bud of the pleurotus eryngii to form intensively by stimulation of low temperature and variable temperature, spraying nutrient solution and covering nutrient soil to promote fruiting bodies to form and grow. The invention also discloses matched formulas of a cultivating culture medium, a nutrient solution and nutrient soil (a culture medium A, nutrient soil A and a nutrient solution A). By adopting the production method of combination of stimulation of low temperature and variable temperature, stripping of the fungus bag and covering of the nutrient soil, and corresponding production formulas, the yield of the pleurotus eryngii can be improved, the growing time of the hypha can be shortened, the cost of the medium is lowered appropriately, and the pleurotus eryngii fruits early and intensively in a certain period.

Description

technical field [0001] The invention belongs to the technical field of edible mushroom cultivation, and in particular relates to a high-yield cultivation method of Pleurotus eryngii and a culture medium thereof. Background technique [0002] Pleurotus ryngii (PleurotuseryngiiQuel.), also known as Pleurotus eryngii Quel., is a new species of rare edible fungus that integrates edible, medicinal, and dietotherapy. The mushroom is rich in nutrients, rich in protein, vitamins, calcium, magnesium, copper, and zinc and other minerals, especially the polysaccharides contained in it can improve the immune function of the human body, and have the effects of anti-cancer, lowering blood fat, moisturizing the stomach and beautifying the human body, and are deeply loved by consumers. The wholesale price of Pleurotus eryngii in the Guangxi market has reached 18 yuan / kg. [0003] Pleurotus eryngii is a low-temperature edible fungus, and the fruiting body will die and rot when the temperatu...
