Agaricus bisporus (commonly known as round mushroom, oceanic mushroom), is a kind of grass rot fungi, low-temperature mushrooms, northern China is rich in straw, wheat straw, the climate is suitable for the growth of Agaricus bisporus, has great potential for development. 1. Agaricus bisporus growth nutrition and conditions nutrition: Agaricus bisporus is a kind of saprophytic bacteria, can not be photosynthesis, in the ingredients, in the crop straw (straw, straw) added the right amount of farm manure (such as cattle, sheep, horses, pigs, chickens And human excrement, etc.), also need to add appropriate amount of nitrogen, phosphorus, potassium, calcium, sulfur and other inorganic nutrients. A reasonable formula is an important basic condition for achieving high yields. Temperature: The growth temperature of mycelia of Agaricus blazei is in the range of 4°C-32°C, the optimum temperature is 22°C-25°C; the growth temperature range of fruiting bodies is 5°C-25°C, and the optimum temperature is 14°C-18°C. Humidity: The moisture content of the culture material should be about 60%, and the moisture content of the cover soil should be 16%-20%. Mycelium growth phase relative air temperature of 60% -70%, fruiting body growth phase of 85% -95%, too dry or too wet on the mycelium growth are unfavorable. pH (PH): Agaricus bisporus should be alkaline, and it is unfavorable to the growth of mycelium and fruit bodies, and it is easy to produce bacteria. The PH value of mycelial growth range is 5-8, the most suitable 7-8. The PH value of the culture material before entering the shed should be adjusted to 7.5-8, and the PH value of soil particles should be 8-8.5. A little lime is added for each harvest of a mushroom spray, in order to maintain the PH value and inhibit the growth of miscellaneous bacteria. Air: Agaricus bisporus is an aerobic fungus, so it must be well ventilated. Illumination: The mycelia and fruit bodies of Agaricus bisporus do not require light, but they can still grow under the condition of general scattered light, but they cannot be irradiated with strong light. The fruiting body grows white and hypertrophy in a dark environment. If the light is too strong, the grown fruit body is hardened, and there are many malformed mushrooms. The value of the product is poor.
