一、经济价值与水土保持作用 连翘(Forsythia suspensa)属木犀科连翘属植物,为多年生落叶灌木。它生长快,保土保水性能好,是绿化荒山保持水土的优良树种。25度以上的陡坡地种连翘两三年以后就能基本控制水土流失。其果实为常用中药,有清热解毒消肿的功效。每年修剪的枝条及落下的叶子还可解决燃料缺乏问题。连翘开花量大,也是很好的蜜源植物。因此,丘陵山区发展连翘,既能保持水土,解决药用急需,又能增加药农的经济收入,具有明显的社会效益和经济效益,有广泛的发展前景。
First, the economic value and role of soil and water conservation Forsythia suspensa (Forsythia suspensa) is a plant Oleaceae Forsythia, perennial deciduous shrubs. It grows fast, soil conservation water is good, is affluent barren hills to maintain good soil and water species.
