饲用灌木资源开发利用研究现状及其对贵州石漠化地区的启示

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。

Research Status of Forage Shrub Resources Utilization and Enlightenment for Rocky Desertification Area in Guizhou Province

According to the engineering need of grassland animal husbandry for national rocky desertification by comprehensive treatment, this paper summarized the forage shrub resources in karst rocky desertification area of Guizhou Province, and comprehensively evaluated its utilization value using the subject theory like the ecology, botany, nutrition, etc. and pointed out that the shrubs represented by Magnolia multiflora，Amorpha fruticosa and Campylotropis macrocarpa were not only rich in nutritional value, but also had strong stress-resistance and comprehensive development and utilization value. This paper also analyzed the existing problems in developing and utilizing these forage shrubs in karst rocky desertification area, and provided counter-measures as vigorously developing non-conventional feed processing industry based on forage shrubs in these areas, which was an important guarantee for developing ecological animal husbandry, and also an effective way to improve the vegetation coverage during the comprehensive treatment process of karst rocky desertification.
