[planting technology] precautions for mushroom growth process

air

The mushroom mycelium is an aerobic fungus that continuously absorbs oxygen and emits carbon dioxide during life activities. In the short-term hypoxia, hyphae consume a lot of nutrients, the hyphae gradually weaken, and when the hyphae are seriously deficient in oxygen, the growth is blocked and the susceptible bacteria are not easy to change color and shorten life.

Light

Mushrooms have different light requirements during different growth periods, and can grow well under complete dark conditions in the early stage. However, when the bag is full, there is no light, the bag does not form a primordium, and the fruiting body does not form under the condition of no light. The greenhouse cover is too dense, resulting in deformed mushrooms, so the primordium is formed. Appropriate lighting must be available during the period of fruiting.

temperature

Because the species of the excellent variety is not very eternal, it is often found that the temperature influence is very different from the temperature change. Some of the original excellent traits gradually disappear or become worse, and the growth potential is delayed, the mushroom is late, the bigfoot mushroom, the yield Not high, good quality and other phenomena, with the cultivation time is too long, lose the ability to resist stress or lose high-yield traits, lose normal physiological functions, so it becomes unable to perform excellent variety or rotten.

pH

The pH of the culture medium suitable for the growth of shiitake mushroom mycelium is 5-6. The pH value of 3.5-4.5 is suitable for the formation of the mushroom primordium and the development of fruiting bodies. During the process of wood decay, the pH value of the mushroom is continuously decreased, thereby promoting the formation of fruiting bodies.

Moisture

In the sawdust medium, the moisture content of the mycelial growth is 60-70%; the suitable water content in the mushroom is 32-40%, and the survival rate is less than 32%, at 10%-15 Mycelial growth was extremely poor under % conditions. During the formation of fruiting bodies, the moisture content of mushroom wood is maintained at about 60%, and the air humidity is preferably 80-90%.
