Mechanisms of the effect of high‑performance ester composite materials on plant growth under soilless conditions

he utilization of highperformance ester materials in addressing soil erosion and conserving water remains a crucial area of research in soil remediation. Currently, however, the mechanism underlying the role of these materials in vegetation restoration remains unclear, hampering the accurate determination of the optimal ratio of highperformance ester composite materials for soil enhancement. To address this issue, this study examines the mechanism of how highperformance ester composite materials affect the germination and growth of plant seeds through soilless cultivation experiments. The results revealed that the highperformance ester composite materials significantly enhanced seed germination ability and fostered plant seedling growth. Notably, the promotional effects of the ester adhesive and waterretaining materials within the highperformance ester composite varied. Specifically, the adhesive material significantly spurred radicle development, while the waterretaining material significantly accelerated germ growth. Varying concentrations of adhesive materials exerted distinct effects on plant growth. In particular, a small amount of adhesive materials enhanced seed germination, whereas excessive amounts exhibited inhibitory effects. Consequently, the optimal adhesive materials dosage conducive to plant growth and the optimal weight ratio of adhesive to waterretaining materials were ascertained. Additionally, the underlying mechanism of highperformance ester composite materials influence plant growth was elucidated. Overall, this research offers a theoretical foundation for the optimal ratio adjustment of highperformance ester composite materials to optimize soil improvement efforts.
