Mushroom fertilization includes adding nutrients to the substrate and fertilizing the mushroom bed.
I. Fertilizing the substrate
The article attributes some reduced yields to low water absorption and nutrient content in cottonseed hulls. It recommends mainly organic supplementation for a broad nutrient supply, particularly late in cropping, with smaller quantities of readily absorbed inorganic nutrients used in combination.
II. Fertilizing the mushroom bed
Common bed treatments listed include mushroom micronutrients, growth regulators such as triacontanol, indoleacetic acid, gibberellin and naphthaleneacetic acid, plus compost extracts, mushroom-base broth, soy milk, poultry-manure extracts, glucose/calcium carbonate, urea/ammonium sulfate, peptone/yeast and wood-ash solutions.
Fertilizing fruiting bodies is another common approach. The article lists mushroom micronutrients, urea, potassium dihydrogen phosphate and humic-acid solutions, as well as commercial liquid biological fertilizers.
III. Precautions for fertilizing edible mushrooms
First, use a fertilization method suited to the mushroom species; an unsuitable method can be counterproductive.
Second, alternate different fertilizers during application, especially inorganic fertilizers containing only a limited range of nutrients.
Third, apply fertilizer moderately. Excessive quantities or overly concentrated solutions can harm mycelial growth.
Fourth, prepare nutrient solutions immediately before use rather than storing them, to prevent deterioration.
Fifth, choose a fertilization method flexibly according to environmental temperature and humidity.
