实验表明，韭菜种子在不同浓度的沼液中发芽结果差异较大。沼液浓度大于５０％时，抑制了韭菜种子的发芽和芽的生长；沼液浓度为１００％时，种子完全不能发芽；沼液浓度低于２０％时，可以促进种子的发芽与芽的生长；最佳沼液浓度为１％～２０％。 Experiments show that the germination of leek seeds in different concentrations of biogas slurry results vary greatly. When the concentration of biogas slurry was more than 50%, the germination and bud growth of Chinese chive seed were inhibited. When the concentration of biogas slurry was 100%, the seed could not germinate completely. When the biogas slurry concentration was less than 20%, the seed germination and bud growth could be promoted The best biogas slurry concentration is 1% ~ 20%.
