Processing method for candied straw mushrooms and button mushrooms
First, it is necessary to understand the tissue structure and chemical composition characteristics of edible fungi such as straw mushrooms and button mushrooms. These edible fungi have a high water content and loose, fragile tissue, and are prone to browning during processing, which affects the color of the finished product. Therefore, the processing technology must take these characteristics into account. The processing techniques are as follows: 1. Raw material selection: Remove rotten, diseased, off-color, aged, and opened-cap straw mushrooms and button mushrooms; use fresh materials as much as possible. 2. Pretreatment: After the raw materials are selected and trimmed, color-protection measures should be carried out promptly and quickly by soaking in 1% salt water, or

Detailed Explanation of Key Technical Points for Autumn Management of Button Mushrooms
To achieve stable and high yields of button mushrooms in autumn, water management must be the key focus. With proper watering, the mycelium grows vigorously, fruiting bodies form abundantly, and the number of fruiting flushes increases; with excessive watering, the mycelium will shrink and recede, primordia will form poorly, and the mushroom fruiting bodies will develop "rust spots" and "red roots"; with insufficient watering, the fruiting bodies will not be plump, and flat caps, sunken caps, or scales on the surface will appear. The key focus of water management should be to increase the relative air humidity, and when spraying water, it should be flexibly controlled according to the fruiting situation, the moisture conditions of the compost and casing soil, and changes in weather. Generally in

What is the suitable cultivation season for the button mushroom?
The button mushroom (Agaricus bisporus) is a low-temperature fruiting fungus; it only produces fruiting bodies below 18°C, and the optimal temperature for mushroom production is around 16°C. Therefore, the cultivation season is mostly arranged in autumn and winter, continuing into early spring. Because of regional climate differences and variations in local microclimates, the cultivation period for mushrooms can be determined based on local meteorological data. Generally, the sowing period is when the local autumn average day-night temperature stabilizes at 22-25°C. Counting back about 23 days from this gives the date for building the compost pile; in the Jiangsu-Zhejiang area this is mid to late August,

Detailed Explanation of the Plastic Shed Cultivation Method for Button Mushrooms
Using plastic film sheds to cultivate mushrooms offers simple construction, easy dismantling, cleaning and disinfection, and good heat and moisture retention, producing mushrooms with high yield and good quality. For the shed site, choose a spot near the village edge with relatively high terrain, convenient water sources, open surroundings, and beneath tree shade with a composting yard. Use wooden strips, bamboo poles, hemp stalks, reeds, rattan, wire and similar materials as building materials. The mushroom shed should face south, with its size and height determined by the terrain and cultivation area. Inside the shed there are 5 to 6 layers, with 65 cm between layers and a width of 1.3 to 1.6 m. Build the shed and the racks at the same time, joining them tightly

Key Points of Compost Fermentation Technology in the Cultivation of Agaricus bisporus (Button Mushroom)
Compost fermentation is divided into the one-phase fermentation method and the two-phase fermentation method. (1) One-phase fermentation method: 1 day before building the heap, cut the rice (wheat) straw into sections and drench it thoroughly with clean water so that it fully absorbs water, then leave it piled for 1 day. 7-10 days before building the heap, wet the dry manure with clean water or urine water, then build it into a heap for fermentation. When building the heap, arrange 1 layer of manure and 1 layer of straw, piling them layer by layer; start watering at the fourth layer, and from the fourth layer to the eighth layer add all of the cake fertilizer, superphosphate, gypsum and half the amount of urea layer by layer. After building 10 layers, the heap height reaches about 1.5 m, the four sides are basically vertical, the top of the heap is shaped like a turtle shell, and the very top is covered with 1 layer of manure. To maintain aeration, 2-3 ventilation holes can be inserted from top to bottom with bamboo tubes at the top of the compost heap. To keep warm and retain moisture, the top of the heap should be covered with straw mats, and plastic film should be used on rainy days. When piling the material, the water content of the compost is required to reach saturation. On the second day after building the heap, measure the material temperature within 50 cm; under normal conditions the material temperature will rise to 70°C. If it does not reach this temperature, find out the cause and take remedial measures as soon as possible. During fermentation, turn the heap once at intervals, supplement auxiliary raw materials, and adjust the water content and pH of the compost. On the second day after building the heap, the material temperature begins to rise, and on the third day the temperature at the center of the heap reaches its highest point (74-80°C). When this temperature is reached, the first turning can be carried out 6-7 days after building the heap. On the day before turning, water the upper part of the heap first, then water layer by layer during turning; after the heap is rebuilt, a small amount of water should flow out around it, indicating that the amount of water added is appropriate. When building the heap, still add the remaining urea from the fourth layer to the eighth layer. 2 days after the first turning, the material temperature can reach as high as 75-80°C. 5-6 days after the first turning, carry out the second turning. The focus of the second turning is to adjust moisture; the appropriate water content is when the compost is squeezed tightly by hand and 3-4 drops of water can be squeezed out. On rainy days, when covering with plastic sheeting, prop it up with wooden sticks so that the inside of the material is ventilated, prevent anaerobic fermentation, and keep the material temperature at 60-65°C. Generally, the third turning can be carried out 4-5 days after the second turning, using the same method as above. If there are lumps of manure, crush them before mixing them in. 4 days after the third turning, carry out the fourth turning. First check the water content of the heap; the method is that when the compost is squeezed tightly by hand, 1-2 drops of water between the fingers is just right. If the moisture is insufficient, adjust it with 1% lime water. If the moisture is too high, spread it out to air for a while first, and rebuild the heap when the moisture is appropriate. At the same time, prepare 0.5% dichlorvos and spray it to kill insects. 3-4 days after the fourth turning, the temperature inside the material is still around 50°C and tends to stabilize; carry out the final turning. During the turning, adjust the water content of the compost to 60%-63% and the pH to 7.5-8.0, and at the same time check whether residual ammonia gas and pests remain in the compost. If there is an ammonia smell, formaldehyde can be used again to neutralize it; if there are insects, 0.5% dichlorvos can be used to kill them. From heap building to entering the house, the compost generally needs to be turned 4-5 times, and the intervals between turnings are usually 7, 6, 5, 4 and 3 days. During the heap-building process, the moisture of the compost should first be wet and then dry, the heap should first be large and then small, and the turning intervals should first be long and then short. Following this principle, the heap temperature can be maintained above 50°C for a long time.
