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.

Key Management Points for Spring Button Mushrooms and Post-Harvest Handling Methods
The button mushroom (Agaricus bisporus) is currently China's largest export earner among edible fungi, with main production areas in Fujian, Shanghai, Hunan, Guangxi and other provinces. At present, it is the spring mushroom management stage, and some key management techniques for this stage are briefly introduced below: Spring mushroom management accounts for about 30% of total yield. After mid-March, as temperatures gradually rise and stabilize above 10°C, the water content of the casing soil can be gradually adjusted to sufficient levels to meet fruiting needs. When adjusting water, first spray the clear supernatant of lime water at pH 8-9; when the temperature is below 15°C, top-dressing fertilizer can be applied together with spraying. Around April

Detailed Explanation of Button Mushroom Cultivation Techniques in Rice Fields (Part 5)
V. Integrated Pest and Disease Control. Integrated pest and disease control should adhere to the principle of prevention first, with prevention being more important than treatment, and to the principle of combining agricultural control, physical control, biological and ecological control, and chemical control. The use of highly toxic and high-residue pesticides must be eliminated, and no pesticides should be used during the mushroom harvesting period. Diseases and deformed mushrooms caused by environmental factors or improper technical management (such as red-foot mushrooms, landmine mushrooms, big-ball mushrooms, scaly mushrooms, etc.), as well as weed fungi (such as Coprinus mushrooms, etc.), should be controlled primarily through integrated measures. Main measures: First, the compost formula must be accurate, and the material

Button Mushroom Spawning Methods and Technical Key Points
(1) Spawning date. In each region, an appropriate spawning period must be chosen according to local climatic conditions. The standard for the optimal spawning period is: during the mycelium-running stage of the compost, the natural temperature should be 24-26°C as far as possible. In the Yangtze River basin area, the spawning period is in early to mid-September; in Shanghai and areas near Shanghai, the optimal spawning period is September 8-12. If spawning is too early, temperatures above 28°C are often encountered after spawning, causing the spawn not to germinate and to die; if spawning is too late, the number of days suitable for fruiting is shortened, making it difficult to obtain high yields. (2) Before spawning

Key Technical Points for Harvesting and Processing Button Mushrooms
The right time to harvest mushrooms is when the partial veil has not yet broken, the cap has not yet opened, and they have reached the size required by purchasing specifications. Harvesting too early results in small mushrooms and low yield; harvesting too late inhibits the formation and growth of the next flush, prolongs the growing cycle, and also affects mushroom quality. This is especially true when the temperature is relatively high (around 20°C) and there is a heavy flush, as the mushrooms very easily become thin mushrooms or open-cap mushrooms. For commercial mushrooms intended for canning, they generally must be harvested promptly once the cap diameter reaches 2-4 cm. Normally they are harvested once a day, but during the peak production period they must be harvested twice a day to prevent the caps from opening and

Detailed Explanation of Key Management Techniques for Spring Mushrooms of the Button Mushroom (Agaricus bisporus)
After the autumn mushroom season ends, following overwintering management, the mushrooms that fruit again in spring are known as spring mushrooms. Because they have gone through the autumn fruiting period and the low-temperature winter stage, most of the nutrients in the compost have been consumed, and the compost mycelium has also been affected by low temperatures; therefore, the vitality of the spring mushroom mycelium is relatively weak, and its fruiting capacity is noticeably lower than that of autumn mushrooms. At the same time, spring temperatures change from low to high, and the number of pests and diseases in the environment gradually increases. Therefore, spring mushroom management must, according to the climatic conditions at the time, effectively regulate the three factors of temperature, moisture and air in the mushroom house, and carry out pest and disease control, etc.
