摘　　要：【目的】探索不同肥料及其配比对白菜产量及品质的影响。【方法】试验设5个处理,分别为不施肥(T1,CK),单施化肥(T2),2/3化肥配施1/3有机肥(T3),2/3化肥+1/6有机肥+1/6秸秆(T4)和纯有机肥(T5)。其中,T2、T3和T4处理氮磷钾含量相同,T5处理与T2、T3、T4处理含氮量相同,不考虑磷钾含量。【结果】T3处理白菜产量及成活率最高,分别为188.01 t/hm2和90.70%,同时具有最高的氮肥农学效率及偏生产力,分别为163.33 kg/kg和696.34 kg/kg;T3和T5处理白菜可溶性糖含量最高,达到2.58%;T5处理白菜VC含量最高,每100 g为30.6 mg。【结论】在该试验条件下,T3处理2/3化肥配施1/3有机肥是较优的混合配施方案。【Objective】To explore the effects of different fertilizers and their ratios on the yield and quality of Chinese cabbage.【Methods】Five different treatments was designed:no fertilizer(T1,CK),single chemical fertilizer(T2),2/3 chemical fertilizer combined with 1/3 organic fertilizer(T3),2/3 chemical fertilizer+1/6 organic fertilizer combined with 1/6 straw(T4),and pure organic fertilizer(T5).Among them,the contents of nitrogen,phosphorus and potassium in T2,T3 and T4 were the same,while the contents of nitrogen in T5 and T2,T3,T4 were the same without considering the content of phosphorus and potassium.【Results】T3 treatment had the highest yield and survival rate of Chinese cabbage,the values were 188.01 t/hm2 and 90.70%respectively,and the highest nitrogen fertilizer agronomic efficiency and partial productivity,the values were 163.33 kg/kg and 696.34 kg/kg respectively.T3 and T5 treatment had the highest soluble sugar content,reached 2.58%,and T5 treatment had the highest VC content,which was 30.6 mg per 100 g.【Conclusion】Under the experiment condition of this study,T3 treatment 2/3 chemical fertilizer combined with 1/3 organic fertilizer was a better mixed application.
