本文论述了腐殖酸-铁(铝)-磷三元复合体的特性,在植物磷、铁营养中的作用、研究意义及研究进展。用从褐煤中提取的两种腐殖酸人工合成两种腐殖酸-铁-磷三元复合体,并用此两种三元复合体中的磷和铁做为黄瓜和小麦的磷、铁营养源。试验结果表明复合体中的磷和铁对双子叶植物具有较高有效性,而对单子叶植物的有效性较低。
This article discusses the characteristics of humic acid - iron (aluminum) - phosphorus ternary complex, the role of plant phosphorus and iron nutrition, research significance and research progress. Two kinds of humic acid-iron-phosphorus ternary complexes synthesized by two kinds of humic acids extracted from lignite were used as phosphorus and iron nutrition for cucumber and wheat with phosphorus and iron in the two ternary complexes source. The experimental results show that phosphorus and iron in the complex are highly effective for dicotyledonous plants and less effective for monocotyledonous plants.
