Mushroom residue can be fed to fish culture
In places where mushrooms are grown, a large amount of waste mushroom residue is produced every year. These mushroom dregs are rich in crude protein, crude fat and nitrogen extracts, as well as calcium, phosphorus, potassium, silicon and other minerals. Therefore, it can be used as a good feed to feed fish.
The method of feeding fish with mushroom dregs is as follows: every time the mushroom room goes out to the mushroom dregs, pick up the mud, gravel, nails, broken glass and other sundries in the dregs, then transfer them to the sun to dry, and crush them into powder with a grinder; then mix them into the fish feed according to the proportion of 20% of the feed, 30% of the feed. In this way, it can not only save fish feed, but also promote fish growth, killing two birds with one stone.

Key techniques for High-yield cultivation of Mushroom in Open Field
There are many factors affecting the yield and quality of mushroom cultivated in open field. From many years of production practice, we found that in the path of obtaining high-yield and high-quality cultivation of mushroom in open field, strain selection, composting of culture material, making of bacterial bed and sowing, field management and integrated control of diseases and insect pests were five key links. Now our research on the key technologies of these five links is summarized as follows, in order to benefit the growers. 1. Strains selected by tissue isolation or other means must be tested for mushroom production before they can be used on a large scale.
