High yield cultivation of Agaricus bisporus in greenhouse
Agaricus bisporus is the earliest cultivated, largest and most productive global mushroom in the world today. The mushroom is thick, tender, nutritious and has a good taste. At the same time Agaricus bisporus is a concentrated by-product of more exports.
- Preparation. 1. Raw materials and ratio. 35 kg of straw, 11.5 kg of cow dung, 0.35 kg of urea, 11.5 kg of superphosphate, 1 kg of lime, 43 kg of late straw, 2.85 kg of cabbage, 0.6 kg of urea, and ammonium bicarbonate 0.20 kg, 1.45 kg of gypsum powder and 1.05 kg of lime.
2. Area and material quantity. The amount of 1,000 square meters of greenhouses to be built is 125,000 kg of straw, 0.4 million kg of cow dung, 0.4 million kg of superphosphate, 0.012 million kg of urea, and 0.035 million kg of lime.
- Composting. In order to increase the yield, the cultivation materials must be subjected to the composting fermentation and heat disinfection after entering the shed (also known as post-fermentation).
1. The process of composting and fermentation (called pre-fermentation): washing grass (pre-wetting of raw materials) → building stacks → turning.
Wash the grass - shake the grass, constantly pouring water into the haystacks, splashing water, soak the grass, and leave it for 2-4 days. The fake heaping process should often be irrigated with water or water to reach the purpose of pre-wetting.
When building a pile, the height of the stack should be increased in the order of cow straw (or cake) after the first straw. The stack width is 1.6-2 meters, and the height is 1.6-1.8 meters. The length of the stack depends on the location; After the heap has been built, a small amount of water must seep out of the heap. To build a heap, sunny days should be covered with grass, and rain should be covered with a thin film to prevent rain from raining. When turning, it needs to be performed when the temperature inside the stack reaches the maximum first and then starts to fall. The whole process of stacking is repeated three times: in accordance with the number of days of 5-4-3: when the first turn is completed, the remaining 50% of the total amount of urea, compound fertilizer and superphosphate are added at the same time, and all the used gypsum is added; The second turnover was carried out 4 days after the first turnover, and a total of 45% of lime was added at the same time; the third turnover was carried out 3 days after the second turnover.
2. Into the shed and disinfection (called post-fermentation). After the fermentation, the pre-fermented culture material is transferred into a mushroom house, stacked on a shelf, and heated in a shed with a carbon furnace or steam. The temperature in the shed is raised to 57-60° C. for 1-2 days, maintained for 10 hours, and then decreased. 48-52°C, a process that lasted 3-4 days was called post-fermentation.
