我国是世界人口大国、粮食大国和用肥大国。发展农业生产具有特别重要的意义。现代农业越来越要求高层次的科学性和技术手段,目的是夺取农业高产、优质和高效,而有助于实现这一目的所采取的化学手段和措施,包括化肥、农药、农膜、除草剂等都是农化服务的内容。笔者涉足腐植酸开发利用工作20余年,接触到不少腐植酸农业应用的资料,感到腐植酸类物质在农化服务方面很有潜力,现仅从作物营养学角度谈谈一点认识,期望能进一步引起土壤农艺学家和从事化肥生产和农化服务工作者的注意。
My country is a populous country in the world, a big grain country and a big country that uses fertilizers. The development of agricultural production is of special importance. Modern agriculture is increasingly demanding high-level scientific and technological means aimed at seizing the chemical means and measures that have been taken to achieve high agricultural output, quality and efficiency, including fertilizers, pesticides, agricultural films, weeds Agents are all agricultural services. I involved in the development and utilization of humic acid for more than 20 years, access to many humic acid agricultural applications, humic acid substances that have great potential in agricultural services, now only from the point of view of crop nutrition point of understanding, hoping to further Caused by soil agronomists and workers engaged in fertilizer production and agrochemical attention.
