| 摘 要： | 试验研究苜蓿Medicago sativa干草在高、低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,对于茎秆未经压扁的苜蓿,其含水量与茎叶比呈一元线性相关;茎秆压扁后,其茎叶比与含水量之间的关系呈指数曲线的变化趋势.采用高水分打捆贮藏,草产量、干物质和粗蛋白含量分别提高1 817 kg/hm2,915 kg/hm2和192 kg/hm2.

| Abstract: | The yield of alfalfa hay and crude protein was studied at high and low 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 to leaf of unpressed stem was line, but was index curve to pressed stem. The yield and dry matter and crude protein of hay baled at high moisture was 1 817 kg/hm~2, 915 kg/hm~2, 192 kg/hm~2 more than that of general bale respectively. |
