氮、磷、钾配施对不同土壤类型小麦-玉米产量及灌水利用率的影响
Effects of Combined Application of Nitrogen, Phosphorus and Potassium Fertilizers on Yield and Irrigation Water Use Efficiency of Wheat and Maize in Different Soil Type Regions
摘要
Abstract
The effects of different combined ratios of nitrogen (N1,N2,N3,N4 were 120,180,240,360 kg/ha for wheat,180,270,360,450 kg/ha for maize respectively),phosphorus (P1,P2 were 90,135 kg/ha respectively),potassium (K1,K2 were 75,150 kg/ha respectively) on the yield and irrigation water use efficiency of wheat and maize under the same amount of irrigation condition were studied in three different soil type regions,Tongxu,Xiping and Anyang,so as to provide scientific basis for rational fertilization for local farmer.The results showed that compared with control (no fertilizer),different combined ratios of nitrogen,phosphorus and potassiun significantly improved the yields and water use efficiency of wheat and maize in all three regions.The yields and water use efficiency of wheat were the highest under the N3P2K2,N3P2K1 and N2P2K1 treatments in Tongxu,Xiping and Anyang respectively,the yields were 8 606 kg/ha,9 977 kg/ha and 10 305 kg/ha,which increased by 28.95％,52.48％ and 32.71％ compared with control,respectively;the irrigation water use efficiency were 9.56 kg/m3,11.09 kg/m3 and 11.45 kg/m3,respectively.The yields and irrigation water use efficiency of maize were the highest under N4P2K2,N4P2K1 and N2P2K2 treatments in Tongxu,Xiping and Anyang respectively,the yields were 10 998 kg/ha,8 828 kg/ha and 11 715 kg/ha,respectively,which increased by 32.44％,55.29％ and 28.21％ compared with control;meanwhile,the irrigation water use efficiency were 12.22 kg/m3,9.81 kg/m3 and 13.02 kg/m3 respectively.For the whole wheat-maize system,the yields and irrigation water use efficiency were the highest under N3P2K2,N4P2K1 and N1P2K2 treatments in Tongxu,Xiping and Anyang respectively,the yields were 19 515 kg/ha,18 576 kg/ha and 21 080 kg/ha,which increased by 30.29％,51.92％ and 24.70％ compared with control respectively;the irrigation water use efficiency were 10.84 kg/m3,10.32 kg/m3 and 11.71 kg/m3,respectively.关键词
