AI Technical Summary

Technical Problem

Existing technologies are insufficient for the efficient utilization of leafy grass and stem resources. Traditional biological liquid organic fertilizers are not thoroughly treated to render them harmless, have insufficient water-soluble organic matter content, and are prone to inactivation of functional live bacteria, resulting in unstable product quality and failing to meet the needs of facility agriculture and green organic planting.

Method used

Using edible grass leaves and stems as the main material, combined with decomposed livestock and poultry manure, rice husk powder, sawdust and other auxiliary materials, as well as microbial compound inoculants, a high organic matter biological liquid organic fertilizer is prepared through three-stage temperature-controlled aerobic fermentation, precise C/N ratio regulation, precision filtration and pasteurization.

Benefits of technology

It achieves high-value resource utilization of processing residues of leafy grass, complete harmless treatment, increases water-soluble organic matter and effective live bacteria count, and ensures stable product quality, making it suitable for facility agriculture and green organic planting.

Abstract

This invention discloses a process for preparing high-organic-matter bio-liquid organic fertilizer based on the leaves and stems of edible grasses, belonging to the field of organic fertilizer preparation technology. This invention addresses the pain points of low resource utilization rate of edible grass leaves and stems, incomplete harmless treatment of traditional bio-liquid organic fertilizers, low water-soluble organic matter content, easy inactivation of functional live bacteria, and unstable product quality. Using edible grass leaves and stems as the main material, it combines carbon sources such as rice husk powder, nitrogen sources such as well-rotted livestock and poultry manure, conditioners, and compound functional microbial agents. The process involves crushing, drying, sieving, homogenizing, mixing, controlling moisture and C / N ratio, three-stage temperature-controlled aerobic fermentation, drying, fine pulverization, and constant-temperature extraction and centrifugation to obtain a basic mother liquor. After precision filtration and pasteurization, the mother liquor is supplemented with macro-elements, micro-elements, and functional microbial agents to obtain the finished product. This process achieves harmlessness and thorough organic matter degradation, resulting in a product with excellent water-soluble organic matter, effective live bacteria count, and total nutrient indicators, with stable and controllable quality, enabling high-value utilization of edible grass waste.
