Pleurotus ostreatus culture medium

Abstract

The invention discloses a pleurotus ostreatus culture medium. The pleurotus ostreatus culture medium comprises the following raw materials in parts by weight: 4-8 parts of lime, 28-32 parts of cow dung, 38-42 parts of straws, 4-10 parts of gypsum, 3-7 parts of urea, 4-8 parts of a cake fertilizer, and 3-7 parts of calcium superphosphate. By increasing the proportion of straws and content of carbon in a culture material, so that the culture medium accords with the growth of pleurotus ostreatus, other certain competitive contaminating fungi can be effectively killed by anaphase fermentation temperature, coefficient for successfully planting the pleurotus ostreatus is increased, nutrition transformation of the culture material is enhanced, the culture medium provides abundant nutrition for mycelia growth, and establishes a base for high production capacity.

Description

technical field

[0001] The invention relates to the technical field of edible fungus cultivation, in particular to a culture substrate of oyster mushrooms. Background technique

[0002] Pleurotus ostreatus, also known as pleurotus, oyster mushroom, black peony mushroom, is a kind of Pleurotaceae under the order Agaricaceae under the basidiomycota. It is a fairly common gray edible mushroom. . The life cycle of Pleurotus ostreatus is similar to that of many higher basidiomycetes, and basidiospores are produced by fruiting body maturation. The basidiospores are ejected from the gills of the mature fruiting bodies, and when they encounter a suitable environment, they grow germ tubes, which are multinucleated at the initial stage and soon form a septum. After a few days, old bacterial skins are prone to appear, and the bacterial skins are tight and hard.

[0003] The growth of Pleurotus ostreatus is inseparable from a good culture substrate, but the Pleurotus ostreatus produc...

Examples

Embodiment 1

[0018] 4 parts of lime, 28 parts of cow dung, 38 parts of straw, 4 parts of gypsum, 3 parts of urea, 4 parts of cake fertilizer, and 3 parts of superphosphate.

[0019] Preparation:

[0020] (1) Mixing: Soak the straw in water for 6 days, then pre-wet the cow dung with the waste water soaked in the straw, control its water content at 51-56%, ferment for 3 days in advance, and then crush the cake fertilizer to 20 -40 mesh, mix soaked straw, soaked cow dung with lime, cake fertilizer, urea, gypsum, superphosphate, and control the pH value to 7.8-8.2;

[0021] (2) Fermentation: Stack the stirred raw materials in the fermentation tank for fermentation treatment. The height of the stack is 3.1-3.3m. During the fermentation process, keep the temperature at 78-82°C and run for 32 hours. Turn the outside of the pile into the pile, turn the top of the pile into the bottom of the pile, and complete the fermentation when the temperature gradually drops to 38-43°C;
