摘要
试验旨在研究不同草原类型天然牧草的产量和品质。试验以内蒙古锡林郭勒地区的草甸草原(MS)、典型草原(TS)、荒漠草原(DS)3种草地为研究对象,对比3种草地牧草的产量和营养成分的差异性。结果显示:草甸草原优势种为大针茅和羊草,典型草原优势种为糙隐子草和羊草,荒漠草原优势种为蒙古野韭和短花针茅。锡林郭勒地区3种草地类型牧草产量数量关系为:草甸草原>典型草原>荒漠草原。研究表明,3种草原类型中,草甸草原天然牧草饲用价值最高,其次为典型草原。
The experiment was to study the yield and quality of natural herbage in different grassland types. The experiment was conducted on meadow steppe(MS), typical steppe(TS) and desert steppe(DS) in Xilin Gol, Inner Mongolia, to compare the differences of forage yield and nutrient composition among three grasslands. The results showed that Stipa grandis P. A. Smirn. and Leymus chinensis(Trin.) Tzvel were the dominant species in meadow steppe. The dominant species in typical steppe were Cleistogenes squarrosa(Trin.) Keng and Leymus chinensis(Trin.) Tzvel. The dominant species in desert steppe were Allium prostratum Trevir. and Stipa breviflora Griseb. The relationship between forage yield and quantity of three grassland types in Xilin Gol was as follows: Meadow steppe > typical steppe > desert steppe. The study indicates that among three grassland types, the feeding value of natural herbage in meadow steppe was the highest, followed by typical steppe.
