本文介绍了两个实验，研究了青贮湿牧草的发酵变化。第一个试验采用可溶性碳水化合物含量为19.6%的义大利黑麦草（Lolium italicum）在4个筒仓中进行。灌装时在两个筒仓中加水，使干物质含量由21.5%降低；到17.0%。虽然所有四种青贮都保存得很好，但湿青贮中发生的气体损失几乎是干燥材料的三倍。在灌装过程中，在一个处理中添加少量土壤（0.1%）对发酵变化没有不利影响。
Two experiments are described in which the fermentation changes in ensiled wet herbage were studied. In the first experiment Lolium italicum, containing 19.6% of soluble carbohydrate, was used in four silos. Water was added in two silos during filling to reduce the dry matter content from 21.5%; to 17.0%. Although all four silages were well preserved the gaseous losses occurring in the ‚wet silages’ were almost three times those obtained from the drier materials. The addition in one treatment of a small amount of soil (0.1%) during filling did not affect adversely the fermentation changes.
In the second experiment, Dactylis glomerata containing 6.2% of soluble carbohydrate was ensiled with and without the addition of water. In this experiment 2% molasses was added to two silos as an additional treatment. The resultant silages were not well preserved although the addition of molasses and water produced a silage of lower pH value than when water alone was added.
