沼液配施对水培油菜产量及品质的影响

通过以沼液、油菜为试验材料,在完全随机区组设计的条件下,利用水培法,研究了不同浓度沼液对油菜产量及品质的影响,结果表明:施用沼液的处理比空白油菜产量平均提高22.64%,处理间达显著水平。其中Vc提高了42.6%,还原糖提高了60.1%,同时沼液处理均能降低油菜中硝酸盐和总酸的含量,分别降低了16.9%,33.6%。

Effects of Biogas Slurry on Quality and Yield of Hydroponic Cole

In this paper,the effects of biogas slurry on growth,quality and yield of hydroponic capsicum and cole were investigated experimentally.A two-way randomized complete-block design was used in this experiment.The results showed that: the yield was increased by 22.64% averagely when biogas slurry was put into the solution,and the difference achieved remarkable level compared to blank experiment.Vc was increased by 42.6%,reducing sugar increased by 60.1%.The contents of nitrate nitrogen and total acid in capsicum and cole were decreased when biogas slurry was used in experiment,and nitrate nitrogen contents decreased by 12.8%,16.9%,respectively.
