腐殖(植)酸与食品源头安全--腐殖(植)酸是构筑食品源头安全的最佳选择

腐殖（植）酸（Humic Acid，以下简称HA）是天然有机化合物。在农业应用上十分广泛，主要有土壤改良剂、肥料、农药、植物生长剂、兽药、饲料添加剂、水产养殖剂等产品。从狭义的角度说，食品生产源头指土、水、肥、药、种等主要生产环节的硬条件。HA与食品生产源头诸要素之问关系密切。HA与土壤：土壤是种植业依赖的生命基础；HA是土壤有机质中的重要组成部分，也是最活跃的部分。HA与水：水是生命之源；HA在水生体系中普遍存在，是转运大多数生命必需物质甚至毒性物质的一种非常好的工具。HA与肥料：肥料是植物的粮食；HA在改良肥料、增加肥效、提高肥料利用率、协调各种营养等方面具有非常重要的作用。HA与农药：农药是植物的保护伞；HA具有提高农药药效、降低农药毒性、保护农业环境的基本条件。HA与种苗：种苗不好，作物不保；HA是孵化种苗的“保育剂”。除土、水、肥、药、种外，HA因其具有生理活性特征，而与种植业相关的诸多因素均有良好的协同作用。在此基础上，由HA开发的农用产品，涉足改土、活水、制肥、制药、种苗处理及其他衍生制剂等6大类产品，足以构筑起立体农业的防护体系，也是构筑食品源头安全的最佳选择。

Humic acid and source security of production food

Humic Acid (HA) is a natural organic compound,and has been widely used in the field of agriculture as a soilconditioner, fertilizer, pesticide, plant growth-promotingsubstance, animal medicine, fodder additive, aquicultureadditive and so on. In narrow sense, the source producing food includes substantial factors, i.e., soil, water, fertilizer,pesticide, seed and so on. However, humic acid are closelyrelated to these factors. HA is an important and active partof soil organic matter; The life source of water containsHA; Fertilizer is food for plants, meanwhile HA play animportant role in modifying fertilizer, increasing fertilizeruse efficiency, harmonizing with all nutrients and so on;Pesticide is a protective umbrella for plants. HA can alsoenhance pesticide efficiency, decrease toxicity, and protectagricultural environment. There are a significant amount ofreports which state that HA have somewhat stimulation ofseed germination and plant growth. By now, about 300 agro-chemicals contain HA, involving in above 6 aspects. It isthus obvious that HA can play an important role in buildingthe defensive system of three dimensional agriculture, andis the best choice for establishing secure source producingfood.
