Detailed Explanation of Underground Shiitake Cultivation Methods and Techniques
Underground shiitake cultivation uses underground tunnels, natural caves and other underground facilities to grow shiitake mushrooms, allowing year-round spawn production and fruiting in all four seasons. This is another new cultivation site for shiitake production after wild forest areas, mushroom houses and plastic sheds. This cultivation method has developed rapidly in China, with a history of more than 20 years, and a complete set of production models for large-scale underground shiitake cultivation has been formed. It can be done both in bags and in blocks. Underground shiitake cultivation makes full use of the low-temperature and moisture-retaining properties of this site, and with the addition of cultivation bed racks and light sources, it can

Detailed Explanation of Shiitake Mushroom Storage Methods and Key Technical Points
After shiitake mushrooms are dried, they easily absorb moisture again if not stored properly. This is especially true during the rainy season when temperatures are high and humidity is great, making mold and insect damage more likely. Therefore, after drying, the shiitake mushrooms should be quickly graded and packed into plastic bags, and a small packet of anhydrous sodium chloride should be added to prevent the sugars in the mushroom body from seeping out and causing discoloration. At the same time, to prevent insect damage, the storage room can be fumigated with sulfur disulfide for 24 hours before storage, and storage should begin only after the residual gas has been expelled.

Causes of Deformed Shiitake Mushrooms in Off-Season Cultivation and Their Prevention and Control Methods
The edible mushroom industry is an important part of agriculture. Vigorously developing the edible mushroom industry can not only promote a virtuous cycle of the ecosystem, but also increase farmers' income and improve agricultural efficiency, achieving an organic unity of economic, ecological and social benefits. With the development of the edible mushroom industry, although shiitake production ranks only second, the economic benefits it delivers should rank first. How to improve shiitake yield and quality is of great significance to the many practitioners in the field. In off-season cultivation of shiitake, deformed mushrooms often appear due to inadequate production management

Harvesting, Processing and Storage Methods for Shiitake Mushrooms Cultivated on Substitute Substrate
(1) Harvesting time The time required from the appearance of mushroom buds to harvest varies with temperature and humidity; generally it takes 7-10 days from budding to maturity. Timely harvesting is an important part of shiitake cultivation, as harvesting too late or too early will affect both yield and quality. The harvesting stage should also be determined according to whether the mushrooms are sold fresh or dried. Generally, for dried mushroom sales and fresh mushrooms for the domestic market, it is best to harvest when the fruiting bodies are 60-80% mature, that is, when the veil has already broken and the cap still curls inward slightly; at this stage the quality is good and the value is high. When fresh mushrooms are for export

What are the correct methods for storing shiitake mushrooms?
1. Dry storage. Shiitake mushrooms are highly absorbent and not easy to store; when their moisture content is high, they are prone to oxidative spoilage and mold. Therefore, shiitake mushrooms must be dried before storage. An appropriate amount of lump lime or dry charcoal and other moisture-absorbing agents must be placed in the storage container to prevent moisture from returning. 2. Low-temperature storage. Shiitake mushrooms must be stored in a cool, ventilated place; if conditions permit, the container holding the shiitake mushrooms can be sealed and then placed in a refrigerator or cold storage for storage. 3. Light-proof storage. The infrared rays in light will raise the temperature of shiitake mushrooms, and ultraviolet rays will trigger photochemical reactions, thereby

Management Methods and Technical Key Points for Shiitake Mushrooms During the Fruiting Period
After the shiitake mushroom logs change color, the mycelium is fully mature and has accumulated rich nutrients. Under the stimulation of certain conditions, it rapidly transitions from vegetative growth to reproductive growth, initiating the differentiation and development of fruiting body primordia, which marks the beginning of the fruiting period. I. Promoting bud formation: Shiitake mushrooms are a type of fungus that fruits under variable temperatures. A certain temperature difference, scattered light, and fresh air are beneficial to the differentiation of fruiting body primordia. During this period, the covering film on the beds is generally removed, and the temperature in the fruiting greenhouse should preferably be controlled at 10-22°C, with a day-night temperature difference of 5-10°C.

Processing Methods and Key Technical Points for Shiitake Mushrooms After Harvest
After harvesting shiitake mushrooms, processing must be organized promptly, striving to pick and dry them the same day to prevent blackening, deterioration, and rotting. Processing and drying methods: 1. Sun-drying. Sun-drying is the most convenient and easiest method for drying shiitake mushrooms, and sun-dried mushrooms have a higher vitamin D content. The method is: spread the harvested shiitake mushrooms promptly on a sunlit grain-drying yard or cement ground. When drying, first place the caps facing up and the stems facing down, arranging them one by one. After drying until half-dry, turn the stems facing up and the caps facing down, until they are more than ninety percent dry. If

A Detailed Guide to Thirteen Methods of Fertilizing Edible Mushrooms
1. Pen Shi Bao: dilute 5 ml per vial in 50 kg of water; it makes mushroom emergence neat and uniform and thickens the mushroom bodies. 2. Ye Mian Bao: use in the same way as Pen Shi Bao. 3. Gao Chan Ling: dilute 125 g per bag in 80 kg of water; it makes mushrooms emerge earlier and in greater numbers, with thick, large, firm bodies. 4. Nong Bao brand Feng Chan Su: 100 ml per bottle, diluted in 200 kg of water; it makes mushrooms emerge earlier and in greater numbers. 5. Naphthaleneacetic acid: dilute 5 g per bag in 60 kg of water; it makes mushroom emergence neat and promotes maturation of the mushroom bodies.

Symptoms and Control Methods of Smut Disease in the Medicinal Plant Sagittaria
Sagittaria, scientific name Sagittaria trifolia L., commonly known as arrowhead, belongs to the family Alismataceae. The whole plant and corms are used as medicine. It has the effects of clearing heat and stopping bleeding, detoxifying and reducing swelling, and dissipating nodules. It is also a vegetable for autumn and winter. It is mostly planted in rice fields after the rice harvest. It is distributed in all provinces and regions of northern and southern China. Symptoms mainly damage leaves, petioles, flowers and corms. On the leaves, yellow to orange-yellow, slightly raised blister spots of varying sizes first appear, and later the blister spots wither and yellow and rupture, releasing small black powder particles, which are the spore masses of the pathogen. Some diseased leaves are deformed and twisted. Leaf

Symptom Identification and Control Methods of Soft Rot in Edible Fungi
Damage symptoms: White bead-like mycelial networks first appear on the surface of the casing soil on the bed. If not treated promptly, they quickly spread and turn water-red. Infection of the fruiting body starts from the stipe and extends to the cap, initially appearing water-soaked, then gradually turning brown, softening, and eventually rotting. Classification: A fungal disease caused by Verticillium dendroides. Disease characteristics: The casing soil carries the pathogen, which spreads mainly through airflow and water droplets in the mushroom house. Control methods: Strictly disinfect the casing soil to cut off the source of infection. When it occurs locally, spray a 2%-5% formaldehyde solution or 800 times
