According to the color of fruiting body, Pleurotus ostreatus can be divided into four types: dark species (black species), light species, milky white species and white species.
3. Dark color (black). The varieties of this color are mostly low-temperature species and wide-temperature species, belonging to Pleurotus ostreatus and Pleurotus ostreatus. And the depth of color changes with the change of temperature. Generally, the lower the temperature, the darker the color, and the higher the temperature, the lighter the color.

Because the leaves and branches of corn or soybean grow luxuriantly in July and August, the ridges and ditches are well sealed and the humidity is high, which is just suitable for the growth of Pleurotus ostreatus fruiting body.
8. Culture material: select whole-axis corncob or whole bundle of beanstalk, soak it in 2% lime water for 24 hours, then take it out, and control the excess water for later use.
9. Cultivation method: two ridges are planted, and one ridge is empty as the working path. Clean the furrows first, then spread a layer of full-axis corncob or bean straw, sprinkle a layer of strains, then spread a layer of material and then sprinkle a layer of strains. Finally, step on it with your feet and cover it with a 2 cm thick soil or plastic film.
10. management: after 20 days of inoculation, hyphae are full of culture materials. If it doesn't rain, mushrooms will grow in a week or so if heavy water is poured once in the arid area. Management methods and harvesting are the same as before.
The above is the introduction of how Pleurotus ostreatus grows.
