Culture medium capable of adjusting water-gas configuration and manufacturing method thereof

Abstract

The invention discloses a culture medium capable of adjusting the water-gas configuration. The culture medium comprises organic components and inorganic components, wherein the inorganic components account for 20%-60% of the volume of the whole culture medium, and the organic components account for 40%-80% of the volume of the whole culture medium; and crushed particles with the particle size of 0.25 mm-3 mm account for 58%-76% of the weight of the inorganic components, and crushed particles with the particle size of 0.25 mm-3 mm account for 58%-76% of the weight of the organic components. According to the culture medium, the mechanical composition, namely particle size distribution, of each particle size is reconstructed, so that reasonable hole size distribution is regulated and controlled, a scientific and reasonable medium water-gas configuration is established, and water, oxygen and nutrition supply of plants is met to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of plant growth substrates, and in particular relates to a cultivation substrate for regulating water vapor configuration and a manufacturing method thereof, and is mainly suitable for cultivation substrates of tomatoes and cucumbers. Background technique [0002] European and American countries started research on substrates before 1950, and developed and produced the first-generation substrate-combined substrate, which is made by mixing two or more materials in different proportions to meet the needs of plants for water, air, and fertilizer. In the more than 20 years after the 1950s, we began to develop the production matrix according to industrial standards, develop a variety of material combinations, and form professional formulas-product formulas. The unified production of products and unified standardized testing make matrix production enter the stage of standardization. Since the mid-1970s, the theor...

AI Technical Summary

Problems solved by technology

[0003]At present, in my country's substrate market, the vast majority of commodity substrates are still produced by mixing and preparing different raw materials in different proportions, and many companies have noticed that the national According to the requirements of local standards, it is targeted and prepared according to the unified standard. However, because the materials are complex and changeable, many matrix formulas can meet the production and use requirements, but when the water and fertilizer are managed in an integrated way, it will often cause matrix ingredients. The degree of decay is different during the stage decomposition period, resulting in product deviation due to the quality of raw materials in the same formula, which makes it difficult to standardize management according to technical regulations. The same water and fertilizer management technology has different effects, resulting in poor results
