摘　　要：采用盆栽试验,对比了沼液与霍格兰营养液做固体基质无土栽培营养液在油菜、菜薹生长发育中的作用。结果表明:以每盆(容积1.5L)300mL霍格兰营养液施肥处理油菜产量最高,以每盆400mL沼液施肥处理菜薹产量最高,沼液处理硝酸盐含量较低,但与霍格兰营养液差异不显著。The effect between biogas slurry and Hoagland nutrient solution on Brassica campestris and rape growth in soilless culture was studied.The results showed that the output with the treatment of 300mL Hoagland nutrient fertilization every pot was the highest.The output with the treatment of 400mL biogas slurry every pot was the highest.Nitrate contentthe with the treatment of biogas slurry was lower,but there was not significant difference with the treatment of Hoagland nutrient fertilization.
