Abstract

Abstract: In order to investigate the effects of different N, P, and K ratios on the photosynthetic physiological characteristics, photosynthetic products, and grain yield of maize （Zea mays L.）, field experiments were conducted to study the differences in leaf photosynthetic material production capacity at different growth stages under different fertilization levels, and to explore the optimal fertilization amount for maize, in order to provide reference for high-yield and efficient fertilization of maize in the central and northern regions of Jilin Province. The results showed that from the jointing stage to the mature stage, the chlorophyll content of maize leaves showed an overall trend of first increasing and then decreasing, while the net photosynthetic rate （Pn）, stomatal conductance （Gs）, and transpiration rate （Tr） of leaves showed an overall downward trend. T10 treatment was the highest, and the intercellular CO₂ concentration （Ci） of leaves showed a trend of first decreasing and then increasing;the soluble protein content, soluble sugar content, and starch content of T10 treatment were the highest from the jointing stage to the mature stage. The soluble protein content and soluble sugar content of corn leaves showed a trend of first increasing and then decreasing, while the starch content of leaves showed a trend of decreasing;reasonable application of N, P, and K had a certain impact on the stem diameter of corn. In addition to N fertilizer playing a decisive role, plant height and stem diameter were also related to P and K fertilizers;the lodging rate of T7 treatment was the highest, while the lodging rate of T1 treatment was the lowest; the maize grain yield under T10 treatment was the highest, with an increase of 176.6% compared to the control T0, and the difference reached a very significant level. Therefore, T10 treatment with N fertilizer level of 3 performed the best in terms of photosynthetic physiological characteristics and grain yield.

Key words: maize（Zea mays L）, fertilization levels, photosynthetic physiological characteristics, photosynthetic products, grain yield
