摘　　要：采用温室盆栽的试验方法,研究了规模化沼气工程沼液和市售两种有机肥料及其组合对小白菜(Brassica chinen-sis L.)的生长、产量及品质的影响。结果表明:沼液和有机肥产品及其组合对小白菜产量和质量均有较大提高,沼液与有机肥产品配伍使用对小白菜生长的促进效果更为明显,沼液与液体有机肥组合处理T5小白菜的鲜重较对照提高了140%;沼液的使用能提高小白菜Vc含量,沼液处理T1小白菜Vc含量较对照提高了84.54%,但与有机肥共同使用有减弱趋势,其机理有待进一步研究。科学合理利用沼液对提高小白菜栽培产量和品质具有积极作用。Effect of biogas slurry from large scale biogas system, two kinds of merchant organic fertilizer, and their com- bined utilization, on yield and quality of pakchoi （Brassica chinensis L. ）, were experimented in greenhouse pots. The re- sults showed that the both biogas slurry and organic fertilizer could increase the production and quality of Brassica chinensis L. , and their combined utilization obtained even better effect, in which the fresh weight increased by 140% comparing with CK. And the results also showed that biogas slurry could increase Vc content of the Brassica chinensis L. by 84.54% com- paring with the CK, but increase of Vc content had somewhat weakened when biogas slurry adopted combining with mer- chant fertilizer.
