| 中文摘要: |
| 施用生物刺激素所带来的改土抗逆促生功能对于提高土壤养分利用效率、促进作物提质增产十分有效，深受功能性肥料行业的关注。本文从分析生物刺激素概念入手，总结了市场上普遍应用的腐植酸、氨基酸、海藻提取物和促生菌的功能特性和作用机制，并归纳了含有这些物质并可作为功能水溶性肥料载体的废弃物资源种类及应用特点，探究其与活性物质复配制备功能水溶性肥料的工艺关键，以期为实现废弃物增值化利用，实现集约化生产中肥料减施、提高作物产量和品质等目标提供产品支撑。 |
| 英文摘要: |
| Biostimulants are becoming widely applied and extended in the fertilizer industry, because of their effects on soil improvement, anti-stress ability enhancement and root growth promotion, which can increase efficient uptake and utilization of soil nutrients, crop yield and quality.This review introduced the concepts of biostimulants, and summarized the functions and related mechanisms of commonly-applied biostimulants in the market, i.e.humic acid, amino acid, seaweed extracts and plant-growth-promoting bacteria(PGPR). The properties and applied characteristics of different organic wastes containing some biostimulating compounds as the main material of functional water soluble fertilizers (WSF)in the industry were presented. The technical keys to compound these organic wastes with some bio-active substances to produce the functional WSF were explored, with the aims to support the value -added utilization of organic wastes, reduce the use of fertilizers, and promote crops忆 quality and quantity. |
