Wood vinegar acidic culture substrate and compounding process thereof

Abstract

The invention relates to a wood vinegar acidic culture substrate and a compounding process thereof. The wood vinegar acidic culture substrate is an acid substrate which can be used for cultivating acid-favored flowers and commercial crops and is obtained by taking wood vinegar liquid and pine barks as raw materials, pre-treating the pine barks, compounding the pre-treated pine barks with garden soil according to a ratio, and utilizing a wood vinegar nutrient solution prepared by compounding the wood vinegar liquid with nutrient elements including nitrogen, phosphorus, potassium and the like to spray and mediate a substrate; the substrate has the characteristics of balanced nutrient content and reasonable physical and chemical properties; and the substrate has accelerating effect on plant growth, improves the biological character of plants and has the effects of improving fruit quality and yield. The technical indexes of the wood vinegar acidic culture substrate are as follows: the pH value is 4.0-5.0, the nutrient content NPK is more than or equal to 4.0g / kg, the conductivity is 1.1-1.5ms / cm and the content of organic matters is 10-20%. According to the wood vinegar acidic culture substrate and the compounding process thereof, an agricultural straw gasified byproduct resource is utilized, so that the pollution to the environment, caused by stacking forestry and agricultural residues, is effectively reduced, and a straw wood vinegar acidic culture substrate is further developed to replace a lot of used grass carbon resources in flower cultivation.

Description

technical field [0001] The invention relates to a wood acetic acidic cultivation substrate and its compounding process. 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. At present, the state has strictly restricted the exploitation. In large-scale forest areas and timber processing factories in our province, a large amount of pine bark is discarded and piled up, which wastes resources, and even improper disposal can easily cause fires and pollute the atmospheric environment. As a by-product of crop straw gasification, wood vinegar is a natural means of production. Its components are mainly acids, ketones, and aldehydes, and contain more than 20 trace elements. Studies have shown that wood vinegar can promote the growth of flowers, blueberries, camellia oleifera and ginseng, and has good insecticidal and sterili...
