Abstract

The invention relates to a biogas residue floriculture substrate and a combining technology thereof. Cow dung biogas residue is adopted as a raw material, and is mixed and combined with wood chips in proportion, and the pH value of the substrate is adjusted through a phosphoric acid solution H3PO4, so as to obtain the nutrition substrate for culture of acidophilous flowers. The substrate has the characteristics of high nutrient contents and excellent physical and chemical properties, provides nutrition for the growth of the flowers and improves the biological characters of the flower. The technical indexes of the substrate are as follows: the pH value is 4.5 to 5.5, the contents of nutrients NPK (Nitrogen, Phosphorus and Potassium) are greater than or equal to 35 g/kg, the electric conductivity is 1.1 to 1.2 ms/cm, and the porosity is 80 to 85 percent. The invention efficiently utilizes methane fermentation residue resources, thereby protecting natural turf resources and effectively reducing environmental pollution caused by stacked waste materials; and the substrate has high nutrient substance contents and excellent physical and chemical properties.

Description

technical field [0001] The invention relates to a flower cultivation substrate of cow dung and biogas residue and a compounding process thereof. Background technique [0002] At present, most of the flower cultivation substrates in my country are peat, and as a natural resource, the exploitation of peat is easy to cause damage to the ecological environment. Many countries have restricted its extraction. However, due to the vigorous development of biogas projects in my country, a large amount of biogas residue and biogas slurry resources are produced. These resources are only used as fertilizers, with low added value and easy to cause environmental pollution. In order to build a new socialist countryside, Heilongjiang Province has vigorously developed the biogas industry. In the past few years, 90% of the biogas digesters have become a bottleneck restricting the healthy and orderly development of biogas projects due to the difficulty in removing slag. The rational utilizati...
