What are the reasons that affect the yield of mushrooms?

Sometimes the yield of Lentinus edodes is very low or even no harvest, which seriously affects the economic income and is a great blow to the growers.

1. Improper selection of mushroom breeding site

If you choose to plant in dark, poorly ventilated or unsanitary places, resulting in serious contamination of miscellaneous bacteria and failure of shiitake mushrooms can not grow normally. Some of them are forced to develop bacteria, but they are poisoned due to poor air circulation and high carbon dioxide content during the mushroom production period, and cannot produce mushrooms or form deformed mushrooms. Therefore, the planting of Lentinus edodes should first choose a place with good ventilation conditions and scattered light, and keep it clean and hygienic, and take good disinfection measures. For the first time, the mushroom planting site should be disinfected by brushing the wall with lime water and sprinkling quicklime on the ground. The quicklime sprinkled on the ground should be cleaned out the next day. The old mushroom farm can be fumigated with formalin. Mushroom farms with pests spray insecticides to eliminate pests before disinfection.

2. Improper selection or preparation of culture materials

Planting Lentinus edodes with raw materials that have been contaminated and agglomerated is easy to cause large-scale pollution or no bacteria. When mixing the culture material, nitrogen fertilizer such as urea is added in excess to the material. After inoculation, the nitrogen fertilizer is easy to be separated and released * * *, which makes the mycelium poisonous and cannot be normally developed. Therefore, we must close the good material selection and ingredients. To clean the raw materials, and do a good job in disinfection treatment, in the ingredients can not be added at will chemical fertilizer, only in the pile material fermentation planting mushrooms, can add appropriate amount of urea to supplement nitrogen source. At the same time, in the process of ingredients, we should pay special attention to the humidity of the culture material, and the moisture content should not be too high or too low, otherwise it will be detrimental to the bacteria.

3. Improper selection of strains

For example, high-temperature varieties are selected in winter, low-temperature varieties are selected in spring, or strains that have been aged or contaminated are sown, which are easy to cause slow or no bacteria, late or no mushroom production. Therefore, when planting Lentinus edodes, appropriate strains should be selected according to the local climatic conditions at that time, and aging or contaminated strains should not be used.

4. Poor management

Lentinus edodes in natural temperature conditions, the management of the mushroom period is light, moisture and ventilation. During the period of mushroom production, scattered light can meet the needs. In the mushroom room, the light is insufficient and the mushroom production is slow. Electric light can be used to supplement the mushroom production to induce the mushroom production. Air humidity is an important condition for the fruiting period. In order to increase the humidity, blindly increasing the amount of water sprayed, or even directly spraying water on the mushroom body, will make some small mushrooms suffocate, and some grown mushrooms will also fester and turn black due to water stains. Therefore, during the period of mushroom production, we should pay attention to the method of replenishing water, preferably spraying into the air, and at the same time, we should also pay attention to ventilation, so as to avoid excessive accumulation of carbon dioxide, resulting in the formation of fruiting bodies or the formation of deformed mushrooms. In addition, unreasonable harvesting also affects the increase of yield. Some mushroom farmers harvest large mushrooms and keep small ones. They want small mushrooms to continue to grow. As a result, they not only cannot grow up, but also prolong the fruiting period and affect the yield of the next mushroom.
