Field sampling of quinoa (Chenopodium quinoa) was conducted at different growth stages to measure changes in major agronomic traits, dry matter accumulation, and nutrient element content. The results indicated that dry matter accumulation in quinoa followed an S-shaped curve, with a critical period between 60 and 90 days after emergence. There were significant differences in the dry matter allocation ratio and nutrient uptake rates among different parts of quinoa (roots, stems, leaves, panicles) at various growth stages. Notably, the uptake of nitrogen (N), phosphorus (P), and potassium (K) peaked between 60 and 80 days of growth, with K having the highest absorption rate, followed by N, and then P, at a ratio of 4.88:1.00:11.00. The distribution of nutrients in quinoa exhibited dynamic change regularity over time, and nutrients were mainly concentrated in leaves and stems during the early growth stage and shifted more towards the panicles in the later stage. Additionally, the agronomic traits of quinoa were also found to be significantly correlated with dry matter accumulation. Root weight, stem weight and panicle weight were positively correlated with plant height, stem diameter and leaf length.
