新型腐植酸磷肥的研究开发进展 张跃文1 张彩凤1 曾宪成2 （1 太原师范学院 太原 030012 2 中国腐植酸工业协会 北京 100120） 摘 要：腐植酸是土壤团粒组织的构造者，亦为肥料运转的“仓库”。煤炭腐植酸资源丰富，属于难得的低碳 材料。在农业生产中，磷肥作为第二大肥无可替代。磷矿资源不可再生，已经面临枯竭。腐植酸对磷肥有着活 化、转化、移动等多重功效，提高磷肥效果已为大家所熟知。开发新型腐植酸磷肥，进一步提升了腐植酸的使 用效率、提高了磷肥的利用效率。二者共同作用，构成了资源综合利用、生产有效结合、产品多重功能的新型 第二大肥种——腐植酸磷肥(H A-P)。该肥一旦形成产业，必将优化化肥结构，改善土壤环境，改良作物品质， 确保农业可持续发展。 关键词：新型肥料 腐植酸 磷肥 反应机理 生产工艺 中图分类号：TQ444.6+5 文献标识码：A 文章编号：1671-9212(2009)04-0001-05 Inspect of Research and Development on New Style Humic Acid-Phosphate Fertilizer Zhang Yuewen1, Zhang Caifeng1, Zeng Xiancheng2 (1 Taiyuan Normal University, Shanxi Province, Taiyuan, 030012 2 China Humic Acid Industry Association, Beijing, 100120) Abstract: The humic acid is the soil crumb structures designer, also for fertilizer revolution “warehouse”. The humic acid from low rank coal is rich in resources, belonging to rare low-carbon organic materials. In agricultural production, the second largest phosphate fertilizer is irreplaceable. Phosphate as non-renewable resources, has been facing the deple- tion. The multiple effects of the humic acid onto the phosphate fertilizer is the activation, transformation, migration and so on. Enhancing the effect of phosphate has been known. Development of the new humic acid phosphate fertilizer, further promoted use efficiency of the humic acid, and raised the phosphate fertilizer use efficiency. The two combined action, constituted new species of the second-largest fertilizer, humic acid- fertilizer (HA-P), which was a comprehensive utilization of resource, the production of effective integration and a multi-function product. Once the fertilizer industry is formed, it will optimize the structure of chemical fertilizer, improve soil environment, promote crop quality, and ensure sustainable development of agriculture.
