When cultivating straw mushrooms, no or little mushrooms are produced on the surface of the culture material, and mushrooms are produced under the culture material, or even on the reverse side of the bed frame, generally due to two situations:
1. The moisture content of the culture material is uneven, and the surface layer is dry, while the moisture content of the lower layer is wet, and it is easy to occur under the culture material or on the reverse side of the bed frame, especially cotton seed shells are more likely to occur. In some cases, because the cottonseed hull has poor water holding capacity, the water easily leaks downwards;
2. The bottom of the culture material is mixed with soil particles, and the water absorption of the soil particles is good, so that the moisture content of the bottom material is more conducive to mushroom production. However, this kind of mushrooms at the bottom are weak in light and light in color, and some are on the opposite side of the bed frame. Due to the influence of the mattress, most of the mushrooms are malformed, and the quality is mostly poor, affecting the value of the product .
