摘  要:
采用温室盆栽的试验方法研究了浓缩沼液对油菜的生长、产量及品质的影响。结果表明,与施用无机营养液及新鲜沼液处理相比较,施用浓缩沼液后,油菜增产19.54%和32.15%,显著降低了油菜中硝酸盐含量,增加氮素吸收量的同时减少了表观氮素损失。

摘  要:
Pot experiment was conducted in greenhouse to determine the effect of concentrated biogas slurry on growth,yield and quality of rape.The results indicated that comparing with applying inorganic nutrient solution and fresh biogas slurry,concentrated biogas slurry increased yield by 19.54% and 32.15% respectively,reduced nitrate content significantly,increased N uptake and so reduced the loss of apparent N.
