摘要
通过油菜盆栽试验研究发现:生物肥料比有机肥表现出更好的增产效果。施用生物肥、有机肥和化肥都不同程度地增加了油菜体内硝酸盐的累积。总的来看,施用生物肥油菜体内硝酸盐含量低于化肥。施用生物肥能提高油菜叶绿素含量,但在各肥料处理之间油菜体内的 VC 含量没有明显的规律性。
Rape is cultured in pots with chemical fertilizer,organic fertilizer and microbio- logical fertilizer.It is found that the microbiological fertilizer can make a larger increase of rape yield than other fertilizers.Nitrate content in rape with using microbiological fertiliz- er is significantly lower than organic and chemical fertilizer.Chlorophyll content also shows higher in rape with microbiological fertilizer treatment than these of organic and chemical fertilizer treatments.However,there is no significant difference of vitamin C content between the control and fertilizer treatments.
