Bioconversion of organic substances of champignon substrates into vermicompost using Extrakon product

Abstract

The purpose. To study the complex effect of transformation of organic matter and formation of plant-microbial systems when using domestic product Extrakon on the used champignon substrates. Methods. Microbiological (method of entering preparations for the destruction of agricultural residues, obtaining a pure culture, studying the cultural properties of colonies), obtaining water extracts from substrates, the «rolls» method, biochemical (determining the fluorescence induction of chlorophyll leaves), statistical (leaf surface area, notching method). The object of the study was the used champignon substrate and the multifunctional biological preparation Extrakon. Results. When using extracts from the used champignon substrate, the stem length of the model object of the wheat of the soft winter variety «Smuglianka» is 24.2% longer, the root length is 4% longer compared to the control. When using extracts from the waste champignon substrate fermented with Extrakon biological product, the length of the plant stem, roots, and dry weight of wheat seedlings were 10.6%, 34.8, and 20.6% higher, respectively, compared to the control. With the use of the used champignon substrate fermented with Extrakon biological product in wheat plants, the area of the root system is increased, which activates the beneficial microflora, which in its turn effectively transforms all its components. Conclusions. The use of Extrakon biological product for fermentation and transformation in biological fertilizer of the used mushroom substrates is proposed. The use of traditional organic fertilizers with the addition of new ones will contribute to the return of organic matter to the biological cycle and increase the morphometric parameters of crop plants.
