摘要
试验研究苜蓿干草在不同水分条件下打捆对苜蓿草产量和粗蛋白产量的影响。结果表明:随着打捆前含水量的逐渐下降,茎叶比增加,叶片损失率增大,对于茎叶未经压裂的苜蓿,其含水量与茎叶比成一元线性相关;茎秆压裂后,其茎叶比与含水量之间的关系呈指数曲线的变化趋势。采用小捆型、高水分打捆贮藏,产草量、干物质和粗蛋白含量分别提高2025kg/ha,1140kgha和247kg/ha。
Influence of the yield that alfalfa hay and crude protein was studied in the different moisture content.The result were showed as follows： with reduced moisture content, the ratio of stem to leaf increased, as well as loss rate of leaf.The correlation of moisture and ratio of stem was line, but was index curve to pressed stem.Based on the small bunch,the yield and dry matter and crude protein of hay baled at high moisture was 1823kg/ha,915kg/ha,195kg/ha more than that of general bale respectively.
