This invention provides a composite biosynergist, its preparation method, and its application. The composite biosynergist is composed of polyglutamic acid, humic acid, fucoidan oligosaccharide, and plant polyphenols. The synergistic effect of the active substances polyglutamic acid γ-PGA, humic acid HA, fucoidan oligosaccharide AOS, and plant polyphenol PP in the composite biosynergist is essentially manifested in microscopic-scale functional complementarity and mechanism closed-loop. It achieves four functional pathways: blocking salt toxicity through chelate channels, ensuring nutrient supply through complexation channels, enhancing nutrient absorption through root-promoting channels, and resisting stress damage through stress-resistant channels. Ultimately, it achieves the macroscopic effect of "improved soil physicochemical properties—enhanced root function—increased crop stress resistance and yield." Its core advantage lies in overcoming the functional limitations of single components and solving the industry pain points of "difficult-to-eliminate salt damage, easy nutrient loss, and unstable improvement effect" in saline-alkali land improvement through molecular-level synergistic effects.

This invention discloses a green and ecological planting method for daylilies, belonging to the field of agricultural planting technology. It addresses the technical problems of excessive reliance on chemical fertilizers and traditional mulching in current daylily cultivation, leading to soil ecological imbalance and low fertilizer utilization. The method includes: applying organic fertilizer made from cow and sheep manure and Asteraceae plant residues through aerobic composting, using a layered strip application method. First, fully decomposed organic fertilizer is applied as a base fertilizer layer in the planting furrow, followed by semi-decomposed organic fertilizer that has completed the main fermentation stage but not the later aging stage as a middle layer fertilizer; after land preparation and ridging, wood ash is spread on the ridge surface, followed by the laying of black fully biodegradable mulch film; finally, holes are made in the mulch film for daylily seedling planting. This method is mainly used for sustainable ecological planting of daylilies, improving soil fertility and structure, regulating soil pH and providing potassium, conserving moisture and suppressing weeds while avoiding residual pollution, thereby increasing daylily yield and quality while reducing environmental impact.
