Abstract
This paper studied the effect of different irrigation and fertilization modes on cotton nitrogen absorption,utilization,distribution and yields under the Variable Control Fertilization mode and the Pressure Differential Fertigation mode.Plot experiment set different fertilization methods and irrigation fertilization modes to measure the total nitrogen of cotton,and eventually analyze cotton nitrogen absorption and utilization and yields under different fertilization methods.The plant nitrogen content and nitrogen fertilizer use efficiency of Variable Control Fertilization mode is higher than that of Pressure Differential Fertigation mode,and the average yield of the former is higher than that of the later by 5.27%.The N-W-N fertilization model with fertilizer nitrogen at both ends of a fertilization process and irrigation in the middle one-third of the process is conducive to promote the growth and development of cotton reproductive organs,to increase the total nitrogen amount allocated in the cotton reproductive organs,to significantly improve the efficiency of nitrogen utilization to finally achieve the effect of increasing production.The fertilization mode(N-W-N)with fertilizer nitrogen at both ends of a fertilization process and irrigation in the middle one-third of the process is recommended.
