Environmental protection type full-nutrition organic cultivation media and production method thereof

Abstract

The invention relates to an environmental protection type full-nutrition organic cultivation media, which is characterized by comprising, by weight, 63-75% of grass charcoal with humic acid content of more than 20%, 3-5% of expanded vermiculite particles, 3-5% of 40-60 mesh eggshell powder, 3-5% of 40 mesh kelp powder, 3-5% of 60-80 mesh maifanite powder, 1% of zinc sulfate, 0.5% of borax, 0.5% of ammonium molybdate, 1% of copper sulfate, 2% of EDTA-Fe, 2-3% of 60-80 mesh selenium-rich slime, 2-3% of 60-80 mesh rare earth slime, 2-3% of volcanic lava particles with a particle size of 3-15 mm, and 2-3% of expanded ceramsite. The preparation process comprises: (1) raw material grass charcoal selection; (2) acid extraction and aging treatment of grass charcoal; (3) raw material matching and mixing stirring (4) ripening and disinfection treatment; (5) organic nutrient supplement and bacterial complement treatment; and (6) low-temperature drying and packaging. The product completely utilizes the unique advantages of nature, safety, environmental protection, nutrition, water retention and the like, and can be widely used in the fields of ecological cultivation, soil improvement, home gardening and the like. In addition, the production method is simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to a kind of high-quality peat as the main raw material, which is an environment-friendly full-nutrition organic cultivation substrate obtained by modern bioengineering technology, and also relates to its production method. Background technique [0002] Most of the existing humic acid liquid fertilizers come from weathered coal, which are treated with alkaline solution and then mixed with certain chemical fertilizers to produce a multi-nutrient organic-inorganic compound liquid fertilizer. Although this product contains a certain amount of humic acid, the molecular structure of humic acid is relatively complex, the degree of aromatization is relatively high, the content of active groups and biological activity are relatively low, and because of the addition of a certain amount of chemical fertilizers, such as urea and ammonium sulfate , potassium sulfate and diammonium phosphate, etc., have changed the molecular structure of humic...

Problems solved by technology

Although this product contains a certain amount of humic acid, the molecular structure of humic acid is relatively complex, the degree of aromatization is relatively high, the content of active groups and biological activity are relatively low, and because of the addition of a certain amount of chemical fertilizers, such as urea and ammonium sulfate , potassium sulfate and diammonium phosphate, etc., have changed the molecular structure of humic acid, and weakened the inherent characteristics of humic acid, which has greatly limited the application effect and application range.
