摘要: 阐述了作物主要根系分泌物与作物种类、生长期以及与所处环境的关系.并从植物的残体分解、作物根系的分泌等方面论述了土壤中酚酸物质的来源、存在形态、吸附机理及其对作物生长发育与土壤生物活性的影响与机制.

关键词: 根系分泌物, 酚酸物质

Abstract: This paper discussed the effect of main crop root exudates the relationship between the kinds and amounts of root exudates and the growth of different kinds of crops and their environments. From the aspects of the decompostion of crop residues and the excretion of root systems, the source, form and adsorption mechanism of soil phenolic acids and their effect on crop growth and soil bio-activity were also elaborated.

Key words: Root exudates, Phenolic acid substances
