Abstract: In order to solve the main problems of dry land wheat production in China, such as low rainfall and uneven seasonal distribution, unreasonable fertilization method, the cultivation mode of dry land wheat was discussed.The experiment comprised four cultivation patterns, namely, conventional cropping with uniform fertilization(CK), furrow planting with uniform fertilization(FP), furrow planting with uniform fertilization but reduction of fertilizer application rate by 25%(FPRF), furrow planting with site-dressing fertilization but reduction of fertilizer application rate by 25%(FPOF). Tiller number, dry matter accumulation in the main growth period, soil water content of 0-200 cm at pre-sowing and maturity, yield, water use efficiency(WUE), partial fertilizer productivity of wheat were compared. Compared with CK, FP promoted soil water storage in the fallow season, thus increased soil water storage before sowing by 5.4%-5.5%, and increased the number of tillers and dry matter accumulation significantly in the main growth period, furthermore, the yield, WUE and partial fertilizer productivity were increased by 10.1%-11.2%, 7.2%-8.6% and 10.3%-11.4%, respectively. Compared with FP, FPRF significantly increased the fertilizer partial productivity by 22.9%-34.6%, had no significant effects on the yield and WUE in the first year, and significantly decreased them in the latter two years, but the above indicators were better than conventional plain cropping. Compared with the other three treatments, the yield, water and fertilizer use efficiency of FPOF were all the best, compared with FP, although the increase of yield and WUE was not significant, but the partial fertilizer productivity, were significantly increased by 35.2%-37.8%, respectively. Therefore, in the dryland of Western Henan, FP is beneficial to improve wheat yield and WUE, reducing fertilizer by 25% will reduce the yield to a certain extent, but it is beneficial to increase fertilizer partial productivity. FPOF is a suitable cultivation measure for winter wheat in arid areas due to synergistically improving yield, WUE and fertilizer partial productivity.
