What are the propagation methods of straw mushrooms? This article explains in detail
Straw mushrooms, also called orchid mushrooms, have a very long history of cultivation in China. At present, they are mainly grown in Guangdong, Hunan, Fujian, Guangxi, Jiangsu and Taiwan, China, and other regions. Straw mushrooms are rich in nutrients and have a very good taste, with tender, smooth and refreshing flesh, and they have high health benefits. The key point is that straw mushrooms are the fastest among all edible fungi to generate economic returns. So how are straw mushrooms propagated? How should they be propagated? Let us understand the specifics below.
1. Cultivation conditions
In fact, the cultivation conditions for edible fungi are relatively strict, so straw mushrooms are no exception, but their cultivation conditions differ greatly from those of many edible fungi. The place where straw mushrooms are grown must have a long and continuous water source and be convenient for irrigation, because straw mushrooms have a very large water demand. Second, the cultivation substrate must be alkaline, which is the biggest difference between straw mushrooms and other fungi. Finally, straw mushrooms cannot carry out photosynthesis, so they must not be exposed to direct sunlight.
2. Propagation methods
There are two propagation methods for straw mushrooms, namely sexual reproduction and asexual reproduction. Sexual reproduction refers to the phenomenon in which straw mushrooms use their own spores to germinate, produce haploids, and then form mycelium under different sex conditions, thereby producing mushrooms. Asexual reproduction refers to a method in which, after multiple rounds of cultivation, spawn is formed, and then inoculation, mycelial growth and mushroom production are carried out. At present, the most commonly used propagation method in daily production is the asexual reproduction of straw mushrooms.
3. Cultivation techniques
The planting time for straw mushrooms in southern China is generally between the end of May and September each year, and the best planting time is the first ten days of July each year, while in northern regions it is suitable to cultivate in June and July each year. If greenhouse cultivation is used, planting can generally be done throughout the year. The most common cultivation techniques for straw mushrooms are five, namely the straw mushroom heap cultivation technique, the plastic foam house year-round cultivation technique, the straw mushroom bag cultivation technique, the straw mushroom bed-type cultivation technique and the straw mushroom bed cultivation technique (for specific cultivation techniques, please consult).
4. Precautions
When planting straw mushrooms, there are many precautions we need to pay attention to, such as nutrients, temperature, humidity, oxygen, pH and light. During the growth and development of straw mushrooms, the most important thing is the moisture content, which is generally controlled at around 70 percent; during the mycelial growth period the humidity is around 80 percent, while during the mushroom emergence stage the humidity must be controlled at around 90 percent. The temperature for mycelial growth must be controlled between 10 and 40 degrees, and the most suitable temperature for straw mushroom growth is between 28 and 32 degrees. Note that the highest temperature must not exceed 45 degrees, and the lowest must not be lower than 5 degrees. Finally, straw mushrooms cannot carry out photosynthesis during growth, but this does not mean that no light is needed at all. Proper light can promote mycelial growth, but it must not be excessive.
The above is what the editor wants to introduce to everyone today about the propagation methods of straw mushrooms and their cultivation techniques.
