To investigate the effects of nitrogen, phosphorus, and potassium fertilizers on the anatomical structure of Jue ma(Argentina anserina L.), the study was conducted on the roots, stems, stolons, and leaves of the Qinghai A. anserina No. 3 variety. The results showed that the application of nitrogen fertilizer alone significantly increased the thickness of root phloem, leaf thickness, cortex thickness and vascular bundle area of stolon; while it significantly reduced the thickness of root periderm, xylem thickness, pith area, epidermal thickness and vascular bundle area of the stem. The application of phosphorus fertilizer alone significantly increased the thickness of root periderm, phloem thickness, pith area, vascular cambium thickness, and stem vascular bundle area; while it significantly reduced root xylem thickness, pith thickness, stem epidermal thickness, and stolon epidermal thickness. The application of potassium fertilizer alone significantly increased root xylem thickness, vascular cambium thickness, pith area, leaf thickness, the cortex thickness and vascular bundle area of stolon; while significantly reducing root pith thickness and stem epidermal thickness. Balanced fertilization with nitrogen, phosphorus, and potassium significantly increased root phloem thickness, xylem thickness, pith thickness, pith area, leaf thickness, the epidermal thickness and cortex thickness and vascular bundle area of stolon; while significantly reducing root periderm thickness. Therefore, the application of nitrogen or phosphorus fertilizer alone mainly promoted the development of the vascular cambium and phloem under the expansion of adventitious roots, and potassium fertilizer alone primarily enhanced xylem development, further improving the root’s ability to transport water and nutrients and promoting the growth and development of the A. anserina root system. Balanced fertilization with nitrogen, phosphorus, and potassium could promote the development of roots, stolons, and leaves, thereby improving the quality and stress resistance of A. anserina.;
