补充资料:聚合草(comfrey)
| 聚合草(comfrey) 紫草科聚合草属的一个种,学名Symphytum peregrinum Ledeb.。多年生草本,为青饲料作物。又称紫草根。原产前苏联。中国主要在长江以北及云贵高原等夏季不太炎热的地区栽培。 全株密布白色短硬毛。根系发达,上部是肉质根,根颈部粗大,可长出大量幼芽和叶片。茎生叶50-70片。多的达200片,叶长40-90cm,宽10-25cm,卵形、长椭圆形或披针形。茎高80-150cm,茎及分枝的顶端着生蝎尾状聚伞花序。花冠长约1.5cm,淡紫色或黄白色。种子为小坚果。耐寒,喜温暖湿润气候,适于排水好,能灌溉,有机质多而特别肥沃的壤土。瘠薄土壤不易栽培。 多用分株、切根育苗和茎秆扦插等方法繁殖,以切根育苗效果最好。可把粗细不同的肉质根切成4-7cm长的根段,密放在苗床上,盖土3-4cm,浇水,保持湿润。约25天出苗,30-40天苗高15-20cm即可移栽。按行距60cm,株距40-60cm定植。栽后浇水,即可成活。易受地老虎等地下害虫为害,叶盛期有粉虱为害。 盛花期茎叶干物质含粗蛋白质18.41%,粗脂肪1.35%,粗纤维14.69%,无氮浸出物41.83%,灰分23.69%。其茎叶含吡咯双烷类生物碱,干茎叶总生物碱含量为0.04%,这种生物碱对家畜肝脏有毒害。故在日粮中所占比例不宜超过25%(按干物质计算),并应与多种饲料搭配。 |
