Causes and Control Methods of Deformed Mushrooms in Greenhouses
1. Hollow white-stem mushrooms. The mushroom stems become loose and white, and in severe cases shrink to form a hollow center. Causes: during the fruiting body growth stage, it is caused by dry air and high temperatures. When the relative air humidity is below 85%, the water content of the casing soil layer is relatively low, and the temperature inside the mushroom house is above 18°C, the mushrooms grow quickly and evaporate water quickly, causing the water absorbed by the mushroom body to be less than the water lost through transpiration. Control methods: spray water promptly during the day to keep the relative air humidity at 90%, and ventilate promptly after spraying water in the morning and evening to lower the greenhouse temperature, keeping it at 14-

How to Cope with Disastrous Weather in Oyster Mushroom Greenhouse Cultivation
The area of oyster mushroom cultivation keeps expanding, cultivation techniques are constantly being renovated and improved, and disastrous weather also disturbs oyster mushroom cultivation from time to time. In winter and spring, the main disastrous weather includes: snowy weather (including blizzards and snowstorm weather), cold wave weather, strong wind and temperature drop weather (including blowing sand and floating dust weather), continuous overcast and foggy weather, continuous low temperature weather, and rare extreme low temperature weather. In summer and autumn, the main types are: rainy weather (including thunderstorms, torrential rain, storms, and continuous rainfall weather), high temperature and dry heat weather (

What to Do When Oyster Mushroom Pinheads Die? Cause Analysis and Control Methods
In oyster mushroom production, due to unsuitable mushroom house environmental conditions and compost, as well as improper management or severe weather and other reasons, pinheads on the mushroom bed often shrink, turn yellow, and eventually die; sometimes pinheads on the bed surface die in batches, seriously affecting yield and economic benefits. For this, the author conducted extensive observational research and summarized the causes of mushroom death and control methods, presented as follows: 1 Continuous high temperatures In autumn mushroom production in northern regions, temperatures go from high to low, which is suitable for the growth and development of oyster mushroom fruiting bodies

Can wine lees be used as a growing substrate for oyster mushrooms?
High-yield method for cultivating oyster mushrooms and other edible fungi using fresh wine lees: 1. Adjust fresh beer lees to pH 8-9 with lime, add 3% corn mixed powder by wet weight and an appropriate amount of mixed hardwood sawdust, and adjust the substrate to about 65%. 2. Weigh dried white wine lees, add 15% corn mixed powder, 4% lime powder, and 130% water, mix well, pile up and ferment. 3. Use bag-type oxygen-permeable filling and inoculation for mycelial growth, and the bed-type casing-soil with film-covering fruiting method for two-stage full-conversion cultivation, or use conventional fruiting management, to achieve high-yield results. To make it easy for mushroom growers to grasp, here we focus on

Detailed explanation of the key technical points for courtyard greenhouse cultivation of oyster mushrooms
Using idle space in farm courtyards to build plastic film mushroom greenhouses for cultivating oyster mushrooms has the advantages of low investment, easy control of temperature and humidity, convenient management, and good returns. The main technical points are as follows: 1. Construction of the mushroom greenhouse: build the mushroom greenhouse facing south, against the west wall or east wall. The site should be slightly elevated to prevent water accumulation. Before building the greenhouse, the ground must be thoroughly cleaned to avoid garbage, weeds, and filth on the ground contaminating the environment inside the greenhouse. Use wooden posts or cement posts for support, and a bamboo pole structure is best for the roof, covered with plastic film and then with straw curtains for shade. Requirements

Indoor Cultivation Techniques for Oyster Mushrooms: A Detailed Guide to Mushroom House Setup
The mushroom house should face south, be built on high, dry ground with good drainage, close to a water source, and in a well-ventilated location; its size can be determined according to specific conditions. The design of the mushroom house must take into account the growth requirements of oyster mushrooms, favoring ventilation, moisture retention, and a certain amount of scattered light. The windows of the mushroom house should be installed on the walls at both ends of the aisle, one above and one below, with the upper window slightly lower than the eaves and the lower window 6-10 cm above the ground. The bed frames inside the mushroom house should be sturdy and neat, and convenient to work with. The bed surface is generally 0.6-1 m wide, and the bed frames generally have 4-5 tiers, with the bottom tier 0

How to cope with severe weather in winter and spring greenhouse oyster mushroom production?
In winter and spring, severe weather such as snowfall, cold waves, strong winds, prolonged overcast fog, and sustained low temperatures often arrives uninvited. In mild cases it causes reduced oyster mushroom yields and lower quality; in severe cases it causes total crop failure. Therefore, prevention of and response to severe weather should be strengthened. Main preventive measures: wipe the greenhouse film to improve light transmittance; inspect the greenhouse facilities to ensure the greenhouse's insulation performance; prepare insulating and warming items such as straw mats and old greenhouse film. Response management measures: Cold wave and strong wind cooling weather: Before a cold wave and strong winds arrive, seal the vents tightly, cover the greenhouse film securely, and add a layer of intact old plastic film over the straw mats.

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

Detailed Explanation of the Method for Making Shiitake Mushroom Spawn for Field Cultivation in Greenhouses
After the spawn logs are made, place them in the stove for sterilization, keeping them at 100°C for more than 16 hours. When mixing ingredients according to the conventional formula, absolutely do not reduce any ingredient in the formula. The raw materials should be fresh and free of mold. The inoculation time is early December. Before inoculation, seal the inoculation room and disinfect it with potassium permanganate at 7 grams per cubic meter and formalin at 13 milliliters per cubic meter for 6 hours; inoculation personnel must also be disinfected before entering the inoculation room to inoculate, and inoculation should not be done on rainy days. After inoculation is completed, carry out a second disinfection, then close the doors and windows for 3 days. After 3 days, open

Can distiller's grains be used as a substrate for growing oyster mushrooms?
It is acceptable to use distiller's grains instead of wheat bran as a supplement for producing oyster mushrooms. The usual amount is about 20%, and the other 70-80% can be cottonseed hulls, sawdust, or similar materials. Because distiller's grains are fairly acidic, some lime or similar material should first be mixed in before use, bringing the pH down to 6-6.5.
