Abstract

The invention discloses a composite plant culturing medium pH and EC regulator comprising bamboo / wood vinegar, humic acids, and brown sugar. According to the invention, the composite medium regulator is prepared from natural non-polluted easy-degradation raw materials with wide sources. With the composite medium regulator, physical and chemical properties of culturing media can be improved, the pH and EC values of the culturing media can be reduced, and the utilization rate of nutrients can be improved. The regulator provided by the invention can be used for replacing natural regulators with short-term effects and artificial regulators with high prices. With the regulator provided by the invention, a problem of relatively high pH and EC values of culturing media (peat, grass peat, and soil) in agricultural productions, forestry productions and floriculture can be solved, and a problem of relatively high costs of common high-molecular compounds can be solved.

Description

technical field [0001] The invention relates to a regulator of environment-friendly materials and a preparation method thereof, in particular to a regulator of pH and EC values ​​of a plant cultivation substrate and a preparation method thereof, and is suitable for the fields of agriculture and forestry. Background technique [0002] Cultivation substrate regulator refers to the general term for substances that can make the physical and chemical properties of the cultivation substrate deteriorate due to changes in external and internal conditions, such as when the pH and EC values ​​are too high, and can adjust the adverse physical and chemical properties to the suitable range of plants and maintain basic stability. Cultivation substrate regulator is an important technology emerging in recent years to restore and adjust the properties of substrates. As a high-tech product that is conducive to the development of my country's substrate cultivation circular economy, it has been ...
