摘　　要：以小白菜为研究对象,通过盆栽试验,研究了沼渣有机无机复混肥对小白菜（Brassica campestris L.ssp.Chinensis L.）生长及品质的影响。结果表明：不同施肥处理均促进了小白菜的生长,与不施肥（CK）相比,小白菜产量提高了20.9%-69.0%,其中猪粪沼渣有机无机复混肥处理小白菜产量最高,分别为352.28g/盆和349.33g/盆,秸秆沼渣有机无机复混肥次之;沼渣与商品有机肥处理对降低小白菜硝酸盐含量,提高小白菜还原型维生素C含量和水溶性糖含量效果优于无机肥处理和沼渣有机无机复混肥处理,沼渣有机无机复混肥处理又要好于无机肥处理。与无机肥处理相比,沼渣有机无机复混肥处理小白菜植株硝酸盐含量降低了7.8%-56.7%,水溶性糖含量提高了13.1%-23.6%,还原型维生素C含量提高了18.0%-38.2%。Using pak-choi（Brassica campestris L.ssp.Chinensis L.）as material,apot experiment was conducted to study the effect of different biogas residue organic-inorganic fertilizations on the growth and quality of pak-choi.The results showed that fertilization promoted the growth of pak-choi and the yields of pak-choi increased by 20.9%-69.0%compared with control.The yields of pak-choi were the highest in the treatment of organic-inorganic fertilizations blended by pig manure biogas residue and were 352.28g/pot and 349.33g/pot respectively,followed by the treatments of organic？inorganic fertilizations blended by straw biogas residue.The treatments of biogas residues and commercial organic fertilizations were better than the treatments of inorganic fertilization and organic-inorganic fertilizations blended by biogas residues in reducing the nitrate content and increasing the contents of reduced VC and water-soluble sugar in pak？choi,and the treatments of organic-inorganic fertilizations blended by biogas residues were better than inorganic fertilization treatment.Compared with inorganic fertilization treatment,the treatments of organic-inorganic fertilizations blended by biogas residues reduced the nitrate contents of pak-choi by 7.8%-56.7%,increased the water soluble sugar contents by 13.1%-23.6%,and increased the reduced VC contents by 18.0%-38.2%.
