Functional type soilless culture substrate using mushroom dreg and biogas residue as raw material

Abstract

A functional type soilless culture substrate using mushroom dreg and biogas residue as raw materials belongs to the agricultural cultivation technical field; the mushroom dreg, the biogas residue and roseite are mixed according to a volume ratio of 1:2:1; 1% of agriculture water-retaining agent and 8% of bacterial enzyme bio-organic fertilizer are added according to weight ratio, and are fully stirred; the mushroom dreg is formed by fermenting and composting waste mushroom dregs generated by oyster mushroom, and the oyster mushroom is cultured by using the culture substrate formed by 50% crushed corncob and 50% cottonseed hulls, and the fermented and composted dregs are aired or dried to have the water content below 15%; the biogas residue is solid material obtained by a residue-liquid separation system after large scale biogas digester fermentation of cow dung generated by an intensified cattle farm, and the processed solid material is aired or dried to have the water content below 15%; the roseite is garden reseite with grain size of 2-5mm; the bacterial enzyme bio-organic fertilizer has valid viable count >= 20 million / gram, and organic matter is >=25%. The beneficial effects are that the substrate uses agriculture and animal husbandry waste like the mushroom dregs and biogas residue as main material, thus reducing environment pollution, reducing production cost, removing non-renewable resource dependency like turf, and providing water-retaining, growth assisting and anti-disease effects.

Description

technical field [0001] The invention relates to a substrate formula in soilless cultivation, and belongs to the technical field of agricultural cultivation. It is a functional matrix formula with fungal residue and biogas residue as the main components, which has the functions of water retention, growth growth and disease prevention. Background technique [0002] Soilless cultivation gets rid of the dependence on soil, and can make full use of space resources such as barren beaches, roofs, and balconies for production, and can overcome the adverse effects of soil-borne diseases, salinization, and compaction caused by soil cultivation, and has high yield and high quality. , controllable and pollution-free and many other advantages. Soilless cultivation forms mainly include substrate cultivation, hydroponics, and aeroponics. Both hydroponics and aeroponics use nutrient solution to provide nutrients, which is costly, and the preparation and management of nutrient solution is ...
