What if the latest Lentinus edodes stick fails to change color?

In the process of Lentinus edodes cultivation, the color conversion of mushroom sticks is a very important link, which generally leads to color conversion failure, which leads to the decline of Lentinus edodes yield and quality, and seriously affects the economic benefits of mushroom farmers. So what should we do if the mushroom stick fails to change color? Let's take a look at the detailed introduction.

1. Conditions for color conversion

The color conversion of Lentinus edodes refers to the transformation condition of mycelium from vegetative growth to reproductive growth. Early-maturing varieties can half change color and half produce mushrooms, while middle-and late-maturing varieties can produce mushrooms only after changing color. The moisture content when changing color is extremely important, the water content of mycelium must be more than 65%, otherwise it will not change color, at the same time, the alleviated humidity must be kept above 80%, and it will not change color even if it is too dry. The temperature needed to change color is 17-23 degrees, and it will not change color if it is below 15 degrees or higher than 26 degrees. At the same time, it will not change color if it is too bright or dark, and it needs a light intensity of 800-2500lks.

2. Reasons for failure

There are many reasons for color conversion failure, one is that there is too much wheat bran in the culture material, which leads to excessive nutrition of the mycelium and can not complete the color conversion; the second is that the mycelium is not yet mature and continues to grow after taking off the bag, resulting in the excessive growth of the mycelium and the failure of color conversion; third, when the temperature of the mycelium is more than 25 degrees or lower than 18 degrees, it will also cause the mycelium to grow or stop growing, and the color conversion will fail. Fourth, the hypha had insufficient humidity after taking off the bag, which led to the loss of water and the failure of color conversion; diseases and insect pests occurred at 05:00, which led to slow color change, thick skin, black color, the passage of time, less mushroom production, many deformed mushrooms and so on.

3. prevention and control measures

First of all, the proportion of wheat bran in the formula should be strictly controlled at about 20%, which should not be too much; after the mycelium is fully mature, the bag is removed, and after the mycelium is mature, the tumor-like bulge in the bag changes from hard to soft, and it turns to brown near the inoculation hole, and the bacterial rod is elastic. It is necessary to grasp the cultivation season and ensure that the temperature is 20-25 degrees when taking off the bag. if low temperature or high temperature occurs after taking off the bag, timely measures should be taken to keep warm or cool down to make it change color normally, and the wet condition of the mushroom bed should be maintained after taking off the bag. at the same time, we should do a good job in the prevention and control of diseases and insect pests.
