实验结果表明 ,低浓度的沼气发酵液对种子发芽有促进作用 ,并有利于芽的生长 ,较高浓度的沼液则会抑制种子的发芽 ,沼液对青菜种子的适宜发芽浓度为 1 %。
The experimental results showed that the biogas fermentation broth with low concentration promoted the seed germination and the growth of the bud, while the higher concentration of biogas slurry inhibited the seed germination. The suitable germination concentration of the biogas slurry to the seed was 1%.
