A detailed introduction to the latest propagation methods for the straw mushroom
The straw mushroom, also called the orchid mushroom, has a very long history of cultivation in China. At present it is mainly grown in China's Guangdong, Hunan, Fujian, Guangxi, Jiangsu and Taiwan, China, and other regions. The straw mushroom is rich in nutrients and its taste is very good too, with tender, smooth and refreshing flesh, and it has high health benefits. The key point is that the straw mushroom is the type of edible fungus that delivers economic returns the fastest of all. So how does the straw mushroom reproduce? How should it be propagated? Let's take a closer look below.
1. Cultivation conditions
In fact, the cultivation conditions for edible fungi are all fairly strict, so the straw mushroom is no exception, but its cultivation conditions differ greatly from those of many edible fungi. The place where straw mushrooms are grown must have a steady, long-lasting water source and be convenient for irrigation, because the straw mushroom's water requirement is very large. Next, the cultivation substrate must be on the alkaline side, which is the biggest difference between the straw mushroom and other fungi. Finally, the straw mushroom cannot carry out photosynthesis, so it must not be exposed to direct sunlight.
2. Propagation methods
There are two ways for the straw mushroom to reproduce, namely sexual reproduction and asexual reproduction. Sexual reproduction refers to the phenomenon in which straw mushrooms use their own spore bodies to germinate, produce haploids, and then form mycelium under different sex conditions, thereby producing mushrooms. Asexual reproduction, on the other hand, refers to a method in which, after repeated culturing, a spawn strain is formed, which is then inoculated, incubated and fruited. At present, the propagation method most commonly used in daily practice is the asexual reproduction of the straw mushroom.
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 early July each year, while in northern regions it is advisable to cultivate in June and July each year. If greenhouse cultivation is used, planting is generally possible all year round. There are five most common cultivation techniques for straw mushrooms, namely the straw mushroom heap-straw cultivation technique, the plastic foam house year-round cultivation technique, the straw mushroom bag cultivation technique, the straw mushroom raised-bed cultivation technique and the straw mushroom bed cultivation technique (for the specific cultivation techniques, please consult).
4. Points to note
When growing straw mushrooms there are many points we need to pay attention to, such as nutrients, temperature, humidity, oxygen, pH and light. During the growth and development of the straw mushroom, the most important thing is the moisture content, which is generally controlled at around 70 percent; during the mycelium incubation period the humidity is around 80 percent, while at the fruiting stage the humidity must be controlled at around 90 percent. The temperature for mycelium growth must be controlled between 10 and 40 degrees, and the temperature most suitable for straw mushroom growth is between 28 and 32 degrees. Note that the maximum temperature must not exceed 45 degrees, and the minimum must not fall below 5 degrees. Finally, straw mushroom growth cannot carry out photosynthesis, but that does not mean it needs no light at all; giving it appropriate light can promote mycelium growth, but it must not be excessive.
