Detailed Explanation of High-Yield Indoor Bed Frame Cultivation Techniques for Straw Mushrooms
1. Basic Conditions for the Growth and Development of Straw Mushrooms 1.1 Nutrition The cultivation material must contain components such as carbon, nitrogen, minerals and vitamins. Therefore, rice straw, wheat straw, hemp stalks, waste cotton, cottonseed hulls, and sugarcane bagasse, which are rich in cellulose, are all raw materials for producing straw mushrooms. Nitrogen-containing compounds are important elements for straw mushrooms to synthesize cell protein. Straw mushrooms can only utilize low-molecular-weight amino acids. Organic nitrogen substances such as wheat bran, rice bran and peptone can serve as nitrogen sources. Straw mushroom cultivation generally does not require the addition of ammonium nitrogen, nitrate nitrogen or urea. In addition to carbon and nitrogen, various minerals such as potassium, magnesium, calcium and phosphorus are also necessary. Generally, cellulosic raw materials already contain sufficient amounts, so no supplementation is needed. When preparing the cultivation material, attention should be paid to the carbon-to-nitrogen ratio of the material. Practice has shown that a carbon-to-nitrogen ratio of 60:1 is most suitable for straw mushroom growth.

Detailed Explanation of the Key Technical Points for Bed-Frame Cultivation of Straw Mushroom
1 Cultivation Time The time for bed-frame cultivation of straw mushroom should be chosen in seasons when the daily average temperature reaches above 25°C. This is because the growth and development of straw mushroom require the room temperature of the mushroom house to be kept above 27°C, and sharp rises or drops in temperature must be strictly avoided to prevent the young mushroom buds from shriveling and dying. According to several years of trials, the sowing period in this county can generally be arranged from early May to early September (if the room temperature is slightly low in May, a gasoline drum can be used for heating). 2 Structure and Requirements of the Mushroom House Ordinary slate-roofed mushroom houses or general tile-roofed mushroom houses require internal sealing with plastic film or
