根据国家石漠化综合治理草地畜牧业工程需要,应用生态学、植物学、营养学等学科理论,综述了贵州省喀斯特石漠化地区饲用灌木资源,并对其利用价值进行综合评价,指出以多花木兰(Magnolia multiflora)、紫穗槐(Amorpha fruticosa)、杭子梢(Campylotropis macrocarpa)等为代表的饲用灌木不但营养价值丰富,而且其抗逆性强,具有综合开发利用价值,并对喀斯特石漠化地区饲用灌木开发利用存在的问题进行分析,提出了解决对策,指出大力发展以饲用灌木为主的非常规饲料加工业是喀斯特石漠化地区发展生态畜牧业的重要保障,也是石漠化综合治理过程中提高植被覆盖率的有效途径。
According to the needs of the comprehensive management of grassland animal husbandry in the national rocky desertification, applying the theory of ecology, botany, nutrition and other disciplines, the resources of forage shrubs in the karst rocky desertification area of Guizhou Province are summarized, and the comprehensive evaluation of their utilization value is made. The shrubs represented by Magnolia multiflora, Amorpha fruticosa and Campylotropis macrocarpa are not only rich in nutritional value, but also have strong resistance and comprehensive development and utilization value This paper analyzes the existing problems of development and utilization of forage shrubs in karst rocky desertification area and puts forward countermeasures. It is pointed out that it is an important guarantee to develop non-conventional fodder processing industry that mainly uses forage shrubs to develop ecological livestock husbandry in karst rocky desertification areas , But also an effective way to improve vegetation coverage in the process of comprehensive management of rocky desertification.
