1982年3月至1985年3月在以白茅为主要优势种的天然草地上进行的定位观察表明,产草量4～10月逐月增加,以10月份为最高,10月至翌年3月逐渐下降,草地牧草的粗蛋白质含量4月至翌年3月逐月下降,以4月份为最高。单位面积粗蛋白质产量与产草量变化规律一致,牲畜的采食率4月至翌年3月逐月下降,单位面积粗蛋白质利用量以4月份为最高。白茅草地多次刈割或放牧可提高其利用价值。
March 1982 to March 1985 in the white dominance of the dominant grass species of natural grassland positioning observation showed that grass production from April to October increased month by month, the highest in October, October to March the following year gradually In April, the crude protein content of grassland decreased from April to next March, which was the highest in April. The crude protein yield per unit area was consistent with that of grass yield. The feed intake of livestock dropped gradually from April to next March, and the utilization of crude protein per unit area was the highest in April. The multiple clipping or grazing of whitegrass grass can increase the value of its utilization.
