DEVELOPING FINE FODDER SHRUBESTABLISHING LONG TERM ARTIFICIAL SHRUB GRASSLAND

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 .
