Detailed Explanation of Key Techniques for Oyster Mushroom Cultivation in Greenhouses
Oyster mushrooms grow fast, have strong stress resistance, come from a wide range of substrate sources, are easy to cultivate and manage, and can be grown in all four seasons. In our province, greenhouse cultivation is the main method. Through extensive research, the author has compiled the cultivation techniques for greenhouse oyster mushrooms as a reference for fellow farmers. 1. Variety selection: In early spring, medium-temperature varieties should be used; in late spring and early summer, medium- and high-temperature varieties should be used; in summer and autumn, high-temperature varieties should be used. 2. Production season: For medium-temperature varieties, stock spawn is made in November-December, and production spawn is made in January-February; for high-temperature varieties

Summer oyster mushroom cultivation is not difficult; punching holes for ventilation and oxygen supply is the key
Summer temperatures are relatively high, and three-dimensional cultivation of oyster mushrooms in plastic bags often leads to severe contamination, and can even cause cultivation failure. Whether the spawn-running stage can be successfully passed is the key to summer oyster mushroom cultivation, and it is also the issue mushroom growers worry about most. Practice has proven that punching holes for ventilation and oxygen supply is an effective method for solving the problems of summer oyster mushroom cultivation. 1. Timing of hole punching Generally done 3-5 days after spawning, when the mycelium turns white, germinates, and begins to extend into the substrate. If holes are punched too early, the mycelium has not yet started to grow and contamination by foreign microorganisms is likely; if holes are punched too late, the mycelium lacks

High-yield technique for bag cultivation of oyster mushroom on fermented coarse sawdust substrate
At present, with the development of the edible mushroom industry, the demand for raw materials is also growing. In recent years, the price of fine sawdust in the three northeastern provinces has soared, while coarse sawdust has become waste (such as the coarse sawdust sifted out through the electric sieve on the chipper and the coarse sawdust produced by the branch and twig crusher). The author used the locally abundant coarse sawdust as the main fermentation ingredient to cultivate oyster mushrooms, and the summary is as follows: 1 Test strain Oyster mushroom 2026, whose mother culture was provided by the Shijiazhuang High-tech Edible Mushroom Station in Hebei. The stock culture was a corn kernel medium, with corn kernels 99% and gypsum 1%. Soak or boil the corn kernels,

Key Techniques for Summer Management of Spring-Planted Oyster Mushrooms
For oyster mushrooms sown in early spring, once summer arrives, rising temperatures and increased humidity not only inhibit the formation of mushroom buds but also encourage the breeding and spread of pests and diseases, making summer management essential. 1. Choose a location with higher ground and good drainage, dig a trench 60-80 cm deep and 50 cm wide, pack the four walls firm, and spread lime powder in the trench, or spray a lime emulsion with 800 times carbendazim solution. If pests or diseases have already appeared in the growing substrate, they should be dealt with first. For those already infected with contaminating microorganisms, scrape off the contaminated areas and soak the mushroom bags or blocks in lime emulsion or 800 times carbendazim solution; for those harmed by insect pests, soak them in 800 times dichlorvos, and after drying, arrange and stack them in the trench to a height of about 40 cm, then fill the trench with sandy loam soil at about 60% moisture content. The covering soil should be 20 cm above ground level, then pat it so that it is moderately firm, with the surface forming an arch shape.

How to prevent deformity in winter oyster mushrooms? These measures must be mastered
1. Blue mushroom: During the growth of the fruiting body, a blue halo forms at the edge of the cap, and even the entire fruiting body turns blue-black, without fading until harvest. Preventive measures: For warming measures, methods such as sunlight, heating, and electric heating are preferable. If burning wood or coal is used for warming, closed heat-transfer and smoke-exhaust pipes should be installed, and it is not advisable to build a stove directly in the mushroom house. 2. Big-foot mushroom: After the primordium forms, the differentiation and development speed of the cap is inconsistent, showing only the stipe growing, thick at the bottom and thin at the top, with no mushroom umbrella growing, and the cap

High-yield Wild-simulated Cultivation Technique for Oyster Mushrooms in Winter and Spring
Oyster mushrooms produced using wild-simulated cultivation techniques not only taste as delicious as wild ones, but also truly achieve ecological, high-quality, high yields. Even in the cold winter and low-temperature early spring seasons, they can be grown in a relatively enclosed shade shed, making full use of ground heat to produce thick, tender, high-quality oyster mushrooms. This method increases yield by more than 60% compared with conventional cultivation methods, and by more than 40% compared with cultivation methods such as mushroom walls, with a biological conversion rate reaching more than 220%. The specific techniques for high-yield, high-quality wild-simulated cultivation of oyster mushrooms in winter and spring are as follows: 1. Mycelium culture: Use high-pressure or atmospheric-pressure sterilization

Detailed Explanation of Key Points of Oyster Mushroom Storage and Fresh-Keeping Techniques
Fresh oyster mushrooms have a high water content and tender, crisp tissue, making them extremely prone to damage. If stored improperly, they easily rot and deteriorate, causing losses to producers. Several storage methods for oyster mushrooms are introduced below: 1. Fresh storage: The storage time of fresh oyster mushrooms at room temperature is greatly affected by temperature and air humidity. When the room temperature is 3°C-5°C and the relative air humidity is around 80%, fresh mushrooms can be stored for one week. As temperature increases, humidity must also increase. When the quantity of mushrooms is small, the oyster mushrooms can be placed in a vat containing a small amount of cold water, and the vat opening sealed tightly; even if the temperature reaches 15°C-16°C, they can be kept fresh for about one week.

Key Technical Points and Detailed Methods for Oyster Mushroom Cultivation
Plastic bag cultivation saves labor, is easy to manage, makes full use of mushroom house space, reduces pests and diseases, and makes cultivation success easier. It is suitable not only for indoor cultivation, but also for cultivation in plastic greenhouses, air-raid shelters and other places, and the bags can also be placed in paddy fields, corn fields and vegetable plots for intercropping with rice, corn and vegetables. This is a new cultivation method that has been widely adopted in recent years. 1. Specifications for plastic bags: choose plastic tubes (open at both ends) 0.03-0.04 cm thick, 24-30 cm wide and 40-50 cm long.

Detailed Explanation of Key Points in Oyster Mushroom Salting Processing Technology
According to previous research results, during sealed storage of packaged bananas, the physiological indicators are: respiration rate below 80 mg carbon dioxide/kg/hour, starch content not less than 9%, soluble sugar content below 2%; the carbon dioxide concentration inside the packaging bag is 5-7%, oxygen not less than 1%, and ethylene below 1 ppm. After bananas are treated with a preservative and then sealed in a plastic film bag, they can also be stored for a relatively long time at room temperature. After removal from storage, the bananas ripen normally and have the characteristic banana flavor. The preservation and freshness retention of bananas is mainly related to pathological

Brine Processing Method and Technical Key Points for Oyster Mushrooms
Oyster mushroom, also known as abalone mushroom, is an edible fungus that can be eaten fresh or processed into canned goods for export, and is extremely rich in nutrients. Brine processing of oyster mushrooms is simple to operate, easy to transport, and offers relatively high economic returns. Grade standards for oyster mushrooms (divided into 2 grades in total). Grade 1 mushrooms: grayish-white in color, 3-12 cm in diameter, without stems; the few with stems must not exceed 1 cm. The tissue is tender, the shape is complete, the edge of the cap has no severe shrinkage or cracks, no mud, sand or other impurities, no pests or diseases, no shrinkage or deterioration, no off-odor, and must not be soaked in water. Grade 2
