What causes oyster mushrooms not to fruit? Let me teach you the solutions

Oyster mushrooms are a relatively common variety of edible fungi. They tolerate a wide range of temperatures, can be cultivated all year round, and are also the easiest among edible fungi to fruit. Unlike other fungal species, they fruit very easily in high-temperature, high-humidity environments. However, if large numbers fail to fruit during cultivation, there must be mistakes in certain methods. Let us take a look at the causes of oyster mushrooms not fruiting and the solutions.

1. Improper variety selection

Choosing substandard spawn during cultivation will lead to failure to fruit. Different oyster mushroom varieties have different suitable growing temperatures. According to their suitable growing temperatures, they can be divided into three types: low-, medium- and high-temperature types. If a high-temperature type variety is chosen but cultivated in a low-temperature environment, it will not fruit.

Solution: When selecting spawn, be sure to choose according to the local climate and temperature, and select varieties suitable for cultivation. It is best to first conduct a fruiting temperature test for the variety, and then put it into large-scale production to reduce cultivation risks.

2. Too high alkalinity of the culture substrate

When preparing the culture formula, some lime powder is added. If too much lime powder is added, the alkalinity of the culture substrate will become too high, affecting the normal growth of the mycelium, thus causing failure to fruit.

Solution: In this situation, do not worry at first. During growth, the mycelium produces certain acidic substances through metabolism, which will continuously neutralize the pH. When it reaches a certain level, it will fruit, though this will have a certain impact on yield.

3. Excessive use of chemicals

During mycelial growth, other contaminant fungi may appear. Generally, the vitality of contaminant fungi is not as strong as that of oyster mushroom mycelium, and the oyster mushroom mycelium can later cover them. However, if the cultivation environment or cultivation practices are improper, these contaminant fungi may grow beyond the oyster mushroom mycelium. At this time, fungicides are used to inhibit the growth of contaminant fungi, or pesticides are used during pest control. Excessive use of these chemicals will kill the oyster mushroom mycelium and cause failure to fruit.

Solution: When using chemicals, be sure to pay attention to the concentration and dosage to prevent harm to the oyster mushroom mycelium.

4. Improper cultivation environment

During cultivation, there are certain requirements for temperature, humidity and light. Extreme environments such as high temperature, low temperature or excessively low humidity will cause oyster mushrooms not to fruit. In addition, oyster mushroom mycelium does not need light during growth, but during primordium differentiation it needs scattered light; otherwise it is unfavorable for fruiting, and in severe cases it will cause failure to fruit.

Solution: The cultivation environment must meet the fruiting conditions of oyster mushrooms. At high temperatures, strengthen ventilation or spray water mist to cool down. At low temperatures, use a greenhouse to raise the temperature. When humidity is low, spray water mist to increase humidity. When light is insufficient, supplement light artificially.
