摘要
通过资料查阅、野外调查、农户访谈及专家咨询,建立贵州威宁喀斯特山区野生饲用植物数据库,分析该区野生饲用植物的科、属和种构成;依据家畜对不同饲用植物的采食性差异,将该区野生饲用植物划分为优、良、中和劣4级,并对其饲用特性及家畜配置进行分析。结果表明,威宁喀斯特山区有野生饲用植物55科227属384种,草本和木本分别占总饲用植物种类的76%和24%;优势科为禾本科、豆科、菊科、蔷薇科和莎草科等10科,其中,禾本科、豆科和莎草科中的优良饲用植物多,具较高饲用价值;木本饲用植物主要为豆科(26种)和蔷薇科(23种)。综合分析认为,威宁喀斯特山区具有特殊生物活性物质的饲用灌木,可作为家畜冬季补饲料组分和生物保健药添加剂,该区草山草坡宜不同类型家畜混合放牧利用,中等饲用价值饲草可作冬季补饲料、天然草地利用与栽培草地建设并重。
The database of the name and the palatability level of each wild feeding plants from available lit-eratures, field investigation, farmer interviews and expert advices in Weining County, Guizhou Province were built. The herbaceous and woody life forms and their feeding values were analyzed. The differences of feeding organ and palatability level of each species in this area, and the wild feed plants were divided into excellent, good, medium and bad levels. The results indicated that the wild feeing plants included 55 fami- lies, 77 generas and 384 species, in Weining County, mainly from Gramineae, Leguminosae, Asteraceae, Rosaceae, Cyperaceae and other 10 families. Herbaceous and woody species respectively accounted for 76% and 24% of the total plants, and the woody/vine plants mainly distributed in Leguminosae （26 spe-cies） and Rosaceae （23 species）. The feeding values of most of species of Gramineae, Leguminosae and Cyperaceae were high. Grazing animal behavior, feeding rate and ration composition of cattle, sheep and goats were different. It was pointed out that the forage shrubs with higher biological active substance could be used as the supplementary feed components or biological health care medicine additives, the mixed graz-ing of different livestock should be putted into grassland management practice in Weining karst area, the wild forage of medium feeding of this area could be used as the supplementary feed in winter and the utili- zation of natural and artificial grasslands was equivalent.
