生物活性水对堆肥腐熟过程的效应研究

Effect of Added the Bacteria Mineral Water in the Process of Compost Fermentation

在以牛粪为原料的堆肥试验过程中,加入生物活性水,具有消除臭味、缩短发酵时间的作用,试验结果表明:①生物活性水的加入使堆肥过程的pH值有所下降,减少了NH4+-N的挥发损失,使养分得到保持;②生物活性水的加入能使堆肥过程中形成的NO3--N含量增加,加入其他辅料后,效果更好;③加入生物活性水后的堆肥产品,对植物的生长具有明显的促进作用。

During the compost experimental process using cow dung as raw material, the Bacteria Mineral Water was added, the odor smell was eliminated, and the fermentation time can be reduced. The results showed： ①Addition of the Bacteria Mineral Water caused slight decrease of pH in the composting process, decreased the volatilization loss of ammonium N, thus the nutrient was kept. ②Addition of the Bacteria Mineral Water increased nitrate concentration, when other materials were added, the effectiveness become more obvious. ③After joins the Bacteria Mineral Water, the compost product has the obvious promoter action to plant＇s growth.
