Why does the mycelium produce mushrooms sporadically?

The normal situation is that after the mycelium has penetrated, it begins to produce mushrooms within a few days of recovery. But sometimes the mycelium only sends the fungus tube 2pg 3, or even lmax 2 appears the fruiting body, which is an abnormal phenomenon. Some advertise that their own strains are excellent "precocious and high-yielding strains", which is a lie. In fact, this situation is a manifestation of the degradation of bacteria. There are also external factors, such as:

The main results are as follows: (1) the amount of bacteria used is too large, and the old strains produce mushrooms.

(2) the loading of fashion is too tight, and the mouth of the cultivation bag opens too early.

(3) the period of low temperature is too long, and the water content is on the high side. Prevention methods: bacteria with degraded performance should never be used, and strains with high quality and strong vitality should be selected for cultivation; the use of bacteria should be controlled within 20%, and the strain block should be broken into the size of walnut; 65% moisture should be strictly mastered when batching, and heating measures should be taken in low temperature season. After the mycelium penetrates, small buds are found in any part of the bag, which proves that the mycelium growth stage has matured, and the next step is the mushroom stage. At this time, the bag mouth should be opened for mushroom production management.
