Cereal straw is a large biomass resource which may potentially be pretreated for biogas production by combined ensiling and storage. Five pilot-scale ensiling experiments were performed with straw of wheat, barley and rye, baled in midi-bales (0.9*1.2*2.0 m) with various water contents (17–68 %), ensiling additives and ensiling periods (173–230 days). The water content in the bales differed depending on previous precipitation but also the time of day for baling. Temperature in wet straw increased to 30 and 63 °C during storage for bales with and without wrapping, respectively, and mean dry weight loss was 5.1 ± 5.9 % and 10.5 ± 7.3 %, respectively.

湿谷物秸秆的打包和青贮作为沼气生产的联合储存和预处理


谷物秸秆是一种巨大的生物质资源，可以通过青贮和储存相结合的方式进行预处理以生产沼气。使用小麦、大麦和黑麦秸秆进行了五次中试规模青贮实验，这些秸秆打包成中捆（0.9*1.2*2.0 m），具有不同的含水量（17-68%）、青贮添加剂和青贮期（173-230）天）。捆中的含水量根据先前的降水以及一天中的捆扎时间而有所不同。对于有包装和没有包装的草捆，湿秸秆的温度在储存期间分别增加到 30 和 63 °C，平均干重损失分别为 5.1 ± 5.9% 和 10.5 ± 7.3%。
