糖蜜草(Melinis minueiflora Beauv)属禾本科多年生草本植物。它适应性强,耐干旱,速生,分孽能力强,易种易管易收,是水土保持和开发山地资源的先锋牧草之一。 一、形态特征 糖蜜草根系发达。种子繁衍的植株生长一年,每株有须根50～80条(不含地面以上的茎节不定根),主要分布在地面以下30～60厘米,水平分布直径25～40厘米。其茎匍匐生长,茎节能产生不定根2～5条,入土后又能放射状发生3～5条侧根。一年生植株能固着土壤的范围达1～1.5平方米。由于根系扩散范围大,又有很强的韧性。因此固土力强,这对于防止水土流失是很有利的。 糖蜜草的茎生长快,节间一般长5～15厘米,最 Melinis (Melinis minueiflora Beauv) is a gramineous perennial herb. It is adaptable, drought-resistant, fast-growing, strong ability to divert, easy to grow easy to manage, is one of the pioneer forage grass and soil conservation and exploitation of mountain resources. First, the morphological characteristics Moray grass roots developed. Seed propagation plant growth for one year, each plant has 50 to 80 fibrous roots (excluding stems above the ground adventitious roots), mainly distributed in the ground below 30 to 60 cm, the horizontal distribution of diameter 25 to 40 cm. Its stems prostrate growth, stems produce adventitious roots 2 to 5, after the earth can occur radially 3 to 5 lateral roots. Annual plant can fix soil in the range of 1 to 1.5 square meters. As the root diffusion range, there is a strong toughness. Therefore, solid earth strength, which is very beneficial to prevent soil erosion. Mogweed stems grow fast, internodes generally 5 to 15 cm long, most
