Abstract

In order to investigate the effects of nitrogen (N), phosphorus (P), and potassium (K) deficiency stress on wheat growth and physiological characteristics, this study used wheat (Xinmai 296) as the experimental material. Four treatments were established: nitrogen-deficient treatment, phosphorus-deficient treatment, potassium-deficient treatment, and full fertilizer application treatment. The chlorophyll, plant height, leaf width and chlorophyll fluorescence parameters were systematically measured from the seedling stage to jointing stage. The results showed that the nitrogen deficiency significantly inhibited wheat chlorophyll synthesis, and its chlorophyll content, plant height, and leaf width were all lower than those of the other treatments. Among the chlorophyll fluorescence parameters, the F_v/F_m value was full fertilizer application treatment > potassium-deficient treatment > phosphorus-deficient treatment > nitrogen-deficient treatment, indicating that nitrogen deficiency had the most significant inhibitory effect on the activity of photosystem II (PSII). In summary, nitrogen deficiency had the most significant inhibitory effect on the photosynthetic system and agronomic traits of wheat, followed by potassium and phosphorus. This study provides a theoretical basis for optimizing wheat nutrient management strategies.
