摘要
近年来，农业生态地质研究取得了可喜的进展。人们普遍认识到地质环境的植物营养库作用。在“岩土－土壤溶液－植物”养分循环系统中，包气带土壤溶液是联结地质环境与农业植物有机体之间的纽带或桥梁，在养分元素的“供给－输送－消耗”系统中起着养分转换、养分输运和调节养分动态平衡的重要作用。
A great deal of progress has been made in recent years in the study of agroecological geology . The effect of the geological environment on nutrient necessary for agriculture has been commonly realized. In this paper, in the “rock and soil_soil solution_plant” nutrient circulation system, soil solution is a tie linking the geological environment and plants, and plays an important role in transforming and transporting nutrients and adjusting nutrient’s dynamic balance within the “supply_transport_consumption” system of nutrient.
