Abstract: To clarify the effect of water on yield and agronomic characters in Cangzhou area, 18 wheat varieties in the north area of Huanghuai were collected for spring irrigation treatment. The effects of irrigation frequency on tiller dynamics, leaf area coefficient, and yield of different varieties were analyzed by indoor and field investigation. The results showed that the yield of wheat increased by 1021.05 kg/hm2 on average by pouring one time water compared with that of 0 water, and 900.00 kg/hm2 on average by pouring two times water compared with that of one time water. During the grain filling stage, the investigation of the flag leaf area suggested that the leaf area of 0 water was the smallest, with an average of 18.15 cm2, the leaf area of one time water was 20.34 cm2, and the leaf area of two times water was the biggest, 24.05 cm2. With the increase of irrigation times, the volume weight of every variety decreased, the number of spike sterility decreased, and the plant height gradually increased. The study showed that the yield loss was 900.00 kg/hm2 by reducing one time irrigation in Cangzhou area.
