摘要
苦丁茶以木犀科粗壮女贞(Ligustrum robustum(Roxb.)Blume)作为植被恢复树种,开展石漠化生态治理种植试验示范。结果表明,苦丁茶(粗壮女贞)在喀斯特山地适应性强,耐贫瘠,生长势强。种植10年的粗壮女贞(苦丁茶)树,叶长平均7.7 cm,叶宽平均2.4 cm;单株一级分枝平均24.2个,单株骨干枝平均6.8个;冠幅平均2.14 m×1.83 m。石山地种植粗壮女贞苦丁茶后,生长迅速,能较快形成茂密树冠覆盖裸露的岩石,枯枝落叶覆盖地表,起到良好的水土保持作用。初步形成了"企业+农民专业合作社+农户"的苦丁茶生产模式,其经济效益、社会效益和生态效益明显。
Taking Kudingcha Tree [ Ligustrum robustum （ Roxb. ） Blurae ] as the species for vegetation recovering tree,the plantation test and demonstration in the ecological administration for rocky desertification was carried on. The results show that Kudingcha tree shows a strong adaptability to the mountainous in Karst region. With strong barren-endurance, Kudingcha tree has a robust growth property. The Kudingcha tree planted in the rocky mountain- ous region grows rapidly ,which could rapidly form luxuriant and thick crown to cover the exposed rock;meanwhile the dead branches and leaves of Kudingcha tree drop down onto the ground, which cover the ground ; and exerted an excellent effect for the water and soil conservation. A Kudingcha industrial model--＂ Enterprise ＋ Farmer＇ s Profes- sional Cooperative ＋ Peasant household＂--was primary were remarkable. established. The economical, social and ecological effects
