多花黑麦草的形态特征不同于多年生黑麦草;多年生黑麦草有细弱的根茎,而多花黑麦草无细弱的根茎;多年生黑麦草的茎扁而短矮,分蘖多,而多花黑麦草的茎圆而高,分蘗少;多年生黑麦草的叶子窄而短,叶耳细小,叶子的颜色较浓,而多花黑麦草的叶子宽而长,叶耳明显,叶子的颜色较淡;多年生黑麦草的穗子上花较小,外(?)无芒,而多花黑麦草的花较多,稃外有芒。多花黑麦草,在我省许多人误认为是一年生牧草,所以不少地方不愿意种植。结果造成多花黑麦草种子大量积压,甚至是“借种还 Lolium multiflorum has morphological characteristics different from perennial ryegrass; perennial ryegrass has weak roots, whereas ryegrass does not have delicate roots; perennial ryegrass has flat and short stems with more tillers, whereas ryegrass Stems round and tall, less tillers; perennial ryegrass leaves narrow and short, thin ears, thick leaves, and rich ryegrass leaves wide and long, obvious auricles, leaf color lighter; perennial black Wheat ears on the smaller flowers, outside (?)
