1.聚合草:(又名紫草根、爱国草)是近年引种成功的,表现较好的优良高产饲料。它是紫草科聚合草属,多年生草本植物。全株密生白色短刚毛,根系发达,再生力强,喜温暖湿润的气候,较耐寒。地上部分主要是长大的叶片,含有丰富的蛋白质、碳水化合物、葫萝卜素、维生素 B_(12)、矿物质等。粗纤维含量较低,是一种很好的高产饲料作物,现已开始大量推广。聚合草开花不结籽,用营养体繁殖,切根繁殖(也可分株繁殖):把不同粗细的根切成4—7厘米长的根段,在苗床上开浅沟,然后把根段平放在沟里,盖土3—4厘 1. Aggregate grass: (also known as comfrey root, Patriotic grass) is introduced in recent years, the good performance of good high-yield feed. It is Symphoricum genus, perennial herb. The whole plant dense white short bristles, developed roots, strong regeneration, like a warm and humid climate, more cold. The ground part is mainly grown leaves, rich in protein, carbohydrates, carotene, vitamin B_ (12), minerals and so on. Crude fiber content is low, is a good high-yield forage crops, has now begun to promote a large number. Aggregate flowering does not seed, with vegetative reproduction, cut root breeding (also ramets breeding): The different thickness of the roots cut into 4-7 cm long root segments, open shallow ditch in the seedbed, and then the root flat segment Put in the ditch, covering soil 3-4%
