沼液水培蔬菜的研究进展

Research Progress on Biogas Slurry Hydroponic Vegetables

沼液是由人畜粪便、作物秸秆、落叶、城市污水等厌氧发酵的产物,含有多种蔬菜生长所需的营养元素。现综述了沼液浓度与成分、沼液对蔬菜产量与品质影响的研究进展,分析了目前沼液用于水培蔬菜所存在的主要问题,对未来应用推广需要研究的科学问题进行了展望。

Biogas slurry was the production from excrement,crops straw,leaves,urban sewage by anaerobically fermented.It contained many kinds of nutrition elements necessary for vegetable-growing.The paper summarized the biogas slurry concentration and composition,researched progress of the influence on vegetable＇s yield and quality,analyzed the current problems and discussed the scientific problems for popularizing biogas slurry application in the future.
