209 the yield of mushrooms by 14.1%. The technological process of growing champignons includes four independent but interrelated technologies: preparation of the substrate (compost), preparation of the covering material, cultivation of the planting material – mycelium (mycelium) and cultivation of the crop. After the compost is covered with mycelium, covering is required – application of covering material. It is necessary for the formation and growth of fruit bodies. At the same time, the cover soil prevents the compost surface from drying out, retains moisture necessary for mushroom growth, promotes gas exchange between the substrate and the external environment, and, due to the slightly alkaline reaction (optimal pH value 7.4), converts acidic products of mushroom metabolism into bound forms. Keywords: edible mushroom, champignon, technological processes of cultivation, covering mixtures, inoculation, compost, solutions of cellulase and succinic acid. Edible mushrooms, in particular, champignons, are a valuable dietary product, as they contain all essential amino acids, fiber, which normalizes the activity of beneficial microflora in the human body, and removes toxic substances, including cholesterol, from the body [1, p. 77; 2, p. 5]. They contain minerals, a number of vitamins, as well as biologically active substances that have antitumor, antiviral, anti- inflammatory and other medicinal properties. At the same time, mushrooms contain few lipids and easily digestible carbohydrates, which makes them low-calorie. The development of the production of edible mushrooms, especially champignons, in Ukraine is gaining wide practical importance [3, р. 810; 4, р. 703]. The technological process of growing champignons includes four independent but interrelated technologies: preparation of substrate (compost); preparation of covering material; cultivation of planting material - mycelium (mycelium); cultivation of crops [5, р. 83; 6, р. 79]. To prepare the cover soil, peat (90%) was used with the addition of sand and chalk (5%). Cover mixtures were also prepared from sandy and light loamy soils, river sand, perlite, zeolite, etc. The components were mixed and sieved through a
