摘要
针对广西草地基况低劣和补播优良牧草改良山地草地特别是石灰岩草地易退化的现状，并根据部分天然石灰岩草地补播优质豆科饲用灌木建立人工灌草丛草地的实践，提出了用速生、高产、优质、耐旱、耐瘠薄、侵占性和竞争力都极强的优质饲用灌木建立人工灌草丛草地的改良措施。它具有简便易行、投资少、见效快、效益高、多用途、可持续利用的特点，并初步筛析出适合广西风土条件的主要优质饲用灌木品种及其建植方法与组合类型，为天然草山草坡改良、山区土地开发利用、毁坏型生境改善提供了新途径。
To the present situation of Guangxi grassland basic state bad and easy to regression of overdrilling fine herbages to improve mountain grassland, especially limestone grassland, and based on the practice of part natural limestone grassland overdrilling fine leguminous fodder shrub to establish artificial shrub grassland. The improving measure of using fodder shrubs of rapid growth, high yield, fine, drought-tolerance, desert-tolerance, intrusive and competitive ability strong to establish artificial shrub grassland had been proposed. It owned the characteristics of simple and easy to practice, little investment efficiency fast, effectiveness high, use more, sustainable utilization. The main fine fodder shrub varieties and their establishing methods and combined types which adapted to Guangxi local conditions were selected out. It had given a new pathway to improve natural mountain grassland, develop and utilize mountain area land, improve destroyed habitat and richen and develop the grassland improving and utilizing theory and practice .
