我国腐植酸资源丰富,分布较广,早在70年代以前就有科研单位进行研究,随后得到国家的重视和有关部门的大力支持。我们根据当地资源并结合实际情况,总结研究了腐植酸类物质在农业上应用的经验教训,制定了开发计划和研究目标,组织了化学、生物、同位素等学科,对其结构性质、生理活性 Humic acid resources in our country rich, widely distributed, as early as the 1970s there are research units, followed by the state’s attention and the strong support of relevant departments. Based on the local resources and the actual situation, we summarized the experiences and lessons learned from the application of humic substances in agriculture, formulated the development plans and research objectives, and organized the disciplines of chemistry, biology and isotopes to study their structural properties, physiological activities
