Exploration on the Regularity of Nitrogen Requirement of Zhoumai 22 in the Condition of Yield Increase of Wheat-maize Integration

[Objective] In this study, the aim was to explore the annual dosage and allocation proportion of nitrogenous fertilizer for Zhoumai 22 in the condition of wheat-maize integration. [Method] The rules of growth and yield variation of Zhoumai 22 under different dosages of nitrogenous fertilizer and different distribution ratios were studied. [Result] With the increase of nitrogenous fertilizer application and distribution rate from maize to wheat, the physiological indexes of Zhoumai 22 population showed an increasing trend, while the yield presented the variation trend of increasing firstly and decreasing then. [Conclusion] Annual amount of nitrogenous fertilizer of 600 kg/hm2 and the distribution ratio of 5：5 in the condition of wheat- maize integration was beneficial to the high yield of the whole year＇s crops and Zhoumai 22.
