Abstract
A split-plot design experiment was performed to study the effect of the coupling of water and nitrogen on photosynthesis characteristics and yield of spring wheat by different water and nitrogen application amount under drip irrigation condition.The results showed that photosynthetic rate,stomatal conductance,and intercellular CO2 concentration under drip irrigation condition were higher than that of conventional irrigation in different treatments of the coupling of water and nitrogen amount,whereas descending rate of chlorophyll content was lower.Photosynthetic rate and chlorophyll content increased with nitrogen amount in the same water amount.The photosynthetic rate with water amount showed the same phenomenon in the same nitrogen amount,whereas chlorophyll content decreased.The tested photosynthesis characteristics and yield in the treatment of W2N3 and W2N2 kept higher during the late growth period,indicating the higher efficiency of water and nitrogen and yielding more.
