蔬菜追肥施用沼液与化肥比较试验

The comparison of the two experiments on the waste liquid of marsh gas and chemical fertilizer applied to vegetables respectively

沼气废液是农村沼气能源利用过程中产生的一种有机废液,与农业生产及环境密切相关。通过在不同蔬菜施用沼液肥与化肥的比较试验,结果表明:西红柿、空心菜、黄瓜使用化肥的成本为114.40元/330m2(平方米);使用沼液肥的成本为20～30元/330m2(平方米);使用沼液肥比化肥分别增收,从而解决了沼气废液利用的一种有效途径,对农村环境保护和生态综合治理将起到一定的促进和废物利用的作用。

The waste liquid of marsh gas, which is closely related with the agricultural production and surrounding environment of, it is a kind of organic waste liquid that can be gained when the marsh gas resources be utilized in rural area. The result of the experiments of applying the waste liquid of marsh gas and chemical fertilizer to these vegetables, such as tomatoes, water spinaches and cucumbers shows that：the form ercost is only RMB 20～30 yuan every 330 Sq. metre, and the latter one is RMB 114.40 yuan every 330 Sq, metre. It＇s clear that the farmers will benefit more from the waste liquid of marsh gas than the chemical fertilizer. Not only does this solve the problem of how to make effective use of the waste liquid of marsh gas, but also it will advance both the environmetal protection in rural areas and unifid ecological administration.
