Adding rice husk to mushroom casing soil brings better planting benefits
In conventional mushroom cultivation management, casing soil is a technically demanding task. There are special requirements for the casing soil's texture, soil aggregate structure, aeration, and water retention and holding capacity. In particular, when making large, medium, and small casing soil particles, it is both labor- and time-consuming, and the labor intensity is high. To effectively solve these problems, the author has repeatedly reformed mushroom casing soil technology since 1990, and finally determined to use surface humus soil from within forest stands or paddy field plough layer soil (sandy loam or clay loam are both acceptable) mixed with 5% fresh rice husk

Adding table salt to oyster mushroom substrate can increase yields
In oyster mushroom cultivation, using carbendazim to control contamination by foreign fungi is effective, but pesticide residues remain in the mushrooms, which is harmful to human health, and the cost is relatively high. According to experiments: when cultivating oyster mushrooms on raw substrate, adding 1.5 kg of table salt per 100 kg of dry substrate (dissolved in advance in a measured amount of water) and mixing thoroughly can prevent infection by foreign fungi and also bring mushrooms out 5-7 days earlier. At the same time, because table salt is rich in sodium, calcium, magnesium and other metal ions needed for oyster mushroom growth, if a 10% salt solution is sprayed in the early stage of fruiting body differentiation and after each flush is harvested, the mushrooms can be free of pesticide residues and their quality

What is the effect of adding plant ash to oyster mushroom substrate
When cultivating oyster mushrooms on raw substrate, adding an appropriate amount of plant ash to the substrate has certain benefits for the growth of oyster mushrooms. Because plant ash is alkaline, it has a disinfecting and sterilizing function and can inhibit the growth of various contaminating microorganisms. At the same time, plant ash contains various trace elements such as calcium, magnesium, iron and phosphorus, which can increase the nutrient content of the substrate. In addition, plant ash has the effect of absorbing heat and raising temperature, which can create a good growing environment for mycelial growth. The method of adding plant ash to the substrate is simple: just add 3%-4% after the substrate has fully absorbed water.
