Abstract

The samples of humic preparations (HPs) containing macro and trace elements for plant nutrition were obtained based on humic acids isolated from brown coal of the Tisul deposit in the Kansk-Achinsk Coal Basin. The biological activity of the humic preparations was tested under laboratory and field conditions with the use of Iren and Novosibirskaya 89 varietal wheat seeds. A comparative assessment of the effects of the concentrations of various elements in the HPs on the growth parameters and productivity of cereals was carried out. The edaphic properties of soil substrates should be taken into account for a more effective use of humic preparations.

褐煤腐植酸的生物活性对宏量和微量元素浓度的依赖性

摘要

基于从 Kansk-Achinsk 煤炭盆地 Tisul 矿床的褐煤中分离的腐殖酸获得含有用于植物营养的常量元素和微量元素的腐殖质制剂 (HPs) 样品。在实验室和田间条件下，使用 Iren 和 Novosibirskaya 89 品种小麦种子测试腐殖质制剂的生物活性。对 HPs 中各种元素的浓度对谷物生长参数和生产力的影响进行了比较评估。为了更有效地使用腐殖质制剂，应考虑土壤基质的土壤特性。
