不同批次青贮玉米效果比较

Comparison of Silage Effects of Different Batches in Jiaxian

全株青贮玉米营养价值比较高,但青贮品质受多种因素的影响,本实验以全株青贮玉米为研究对象,对不同时期收获的全株玉米添加微生物青贮剂,通过分析青贮效果得出,处理1、处理2、处理3,水分含量高(依次为80.5%、82.2%、82.6%)、干物质含量低(依次为19.5%、17.8%、17.4%),影响青贮品质;处理4的干物质含量为69.3%,水分含量为30.7%,达到理想的青贮效果。

The whole plant silage corn has high nutritional value,but the silage quality is affected by many factors.This experiment takes the whole plant silage as the research object,and analyzes the silage effect by adding microbial silage agent to the whole plant corn harvested in different periods.The results showed that treatment 1,treatment 2 and treatment 3 had high moisture content(80.5%,82.2%,82.6%)and low dry matter content(19.5%,17.8%,17.4%);The dry matter content(69.3%)and the moisture content(30.7%).
