[目的]明确有利于提高白菜产量和经济效益的适宜的有机肥和氮肥用量。[方法]在磷肥、钾肥用量一致的基础上，设置4个有机肥和氮肥用量进行单独施用和配合施用，研究有机肥、氮肥不同用量对白菜经济性状、产量和经济效益的影响。[结果]无肥区白菜产量最低，仅11075．0 kg／hm2，施肥处理中只施用有机肥区产量最少，仅12937．5 kg／hm2，商品有机肥3000．0 kg／hm2，尿素150．0 kg／hm2，普通磷酸钙300．0 kg／hm2，硫酸钾375．0 kg／hm2处理的产量最高，达19525．0 kg／hm2，经济效益也最大，达29287．5元／hm2。[结论]白菜作物大面积栽培建议施用商品有机肥3000．0 kg／hm2、尿素150．0 kg／hm2、普通磷酸钙300．0 kg／hm2、硫酸钾375．0 kg／hm2，该配比既能提高白菜产量，又能促进有机肥与化肥互补，有利于作物吸收。%Objective] To research the proper dosages of organic fertilizer and nitrogenous fertilizer to enhance the yield and economic benefits of Chinese cabbage.[ Method] Based on the same dosage of phosphate fertilizer and potash fertilizer , four dosages of organic fertilizers and ni-trogenous fertilizers were designed for single application and combined application.[Result] Yield of no fertilizer region was the lowest, which was only 11 075.0 kg/hm2 .Among the fertilizer application treatments, single organic fertilizer treatment had the lowest yield, which was only 12 937.5 kg/hm2;while treatments of 3 000.0 kg/hm2 commerical organic fertilizer,150.0 kg/hm2 urea, 300.0 kg/hm2 ordinary superphosphate and 375.0 kg/hm2 potasslium sucfate was the highest, which was 19 525.0 kg/hm2; and their economic benefits were the maximum, reaching 29 287.5 yuan/hm2.[Conclusion] Research showed that based on large-area cultivation of Chinese cabbage, we suggest to adopt the treatment of 3 000.0 kg/hm2 organic fertilizer, 150.0 kg/hm2 urea, 300.0 kg/hm2 ordinary superphosphate and 375.0 kg/hm2 potassium sulfate.This treatment could enhance the yield of Chinese cabbage , promote the mutual complementation between organic fertilizer and chemical fertilizer , and is helpful to the crop absorption.
