What are the precautions for growing straw mushrooms? Keep these key points in mind
Straw mushroom, also known as orchid mushroom, is the third largest cultivated edible fungus in the world. China's annual straw mushroom output ranks first in the world. It is delicious and nutritious, and is deeply loved by people on the market. However, it has relatively strict requirements for the cultivation environment. Below, let's take a look with the editor at the precautions for growing straw mushrooms.
1. Culture substrate
Straw mushroom has relatively strict requirements for the cultivation environment. Its growth generally requires compound minerals and nitrogen to provide nutrients, and also needs certain vitamins, so rice straw can be selected during cultivation, but clean rice straw must be chosen, and damp or moldy straw must not be chosen. If there is no rice straw, waste cotton, peanut vines and other crops can also be selected, and applying some cow dung and cornmeal can serve as its nutrient source. In addition, unlike other edible fungi, its edible fungus needs to be alkaline, so pay attention to this point.
2. Temperature
Straw mushroom has high requirements for temperature. It is itself a high-temperature fungus. The suitable growth temperature is between 28-30 degrees, the maximum should not exceed 40 degrees, and the minimum must not be lower than 10 degrees, otherwise its growth will stop and in severe cases it will lead to death. Therefore, during cultivation, always pay attention to temperature changes. In winter, when the temperature is lower, the temperature of the mushroom shed should be raised to the range suitable for its growth; while in summer, when the temperature is higher, cooling measures should be taken well.
3. Light
The biggest difference between straw mushroom and other fungi is light. During growth, it cannot absorb carbon dioxide and water and convert them into organic matter, so during cultivation, be sure to pay attention: it should not be directly exposed to sunlight. During cultivation, weak scattered light is sufficient. It should not be directly exposed to sunlight, especially during periods of high temperature and strong light in summer, otherwise it will seriously affect yield and quality.
4. Humidity
Due to its special characteristics, it has a great demand for moisture and oxygen, and it can carry out photosynthesis without light, so during cultivation, windows must be opened in a timely manner for ventilation and air exchange to release carbon dioxide and increase its demand for oxygen. It also has a relatively large demand for moisture, but it must not be directly soaked in water, lest it die. The water content of the culture material is most suitable when controlled at 70%.
