聚合草属紫草科(Boraginaceae)聚合草属(Symphytum),是一种具有宿根、再生能力强、高产、优质的青饲料作物,是猪、牛、羊、兔、鸡、鸭等畜禽的良好饲料,也可用来搭配调制颗粒饲料。聚合草因其花粉败育率高,雌蕊为干燥型,开花不结实,所以一般均采用分株或切根繁殖。目前在我国严重影响其推广的关键问题:北方冻害烂根死苗,南方热害烂根死株也较严重,目前尚未找到有效防治的途陉。用分株或切根繁殖方法极易感染致
Symphytum Boraginaceae is a kind of green fodder crop that has the characteristics of perennial rooting, high reproductive ability, high yield and good quality. It is good for livestock such as pigs, cattle, sheep, rabbits, chickens and ducks Feed, can also be used with the modulation of pellet feed. Polymerization grass because of its high rate of pollen abortion, pistils dry type, flowering is not strong, it is generally used ramet or root cutting propagation. At present, the key issues that have seriously affected their promotion in our country are the freezing and rotting of the dead roots in the north, the severe death of the rotting roots in the south, and no effective prevention and control measures have yet been found. With ramets or cuttings breeding method is extremely vulnerable to infection
