对长江2号、邦德、特高、海湾、安哥斯5个多花黑麦草品种3种播种量(高22.5kg/hm2、中15kg/hm2、低7.5kg/hm2),采用随机分区设计,在山西晋中地区的生产适应性进行了试验研究。在抽穗期、成熟期测定其常规营养成分,筛选出适宜当地气候条件的优质多花黑麦草品种。结果表明,在抽穗期和成熟期,5个品种的OM含量存在显著差异(P<0.05)。CP含量随生育期的推进而降低,不同品种之间存在显著差异(P<0.05);NDF表现出逐渐上升的趋势;ADF含量表现出差异显著(P<0.05)。
Three sowing rates (high 22.5kg / hm2, medium 15kg / hm2, low 7.5kg / hm2) of five ryegrass varieties on the Yangtze River 2, Bond, Tego, , Shanxi Jinzhong in the production adaptability of the pilot study. At heading and maturity, their regular nutrition components were determined, and the best quality ryegrass varieties suitable for local climatic conditions were screened out. The results showed that there were significant differences in OM content of five cultivars at heading and maturity (P <0.05). The content of CP decreased with the growth period, there was significant difference among different varieties (P <0.05); NDF showed a gradual upward trend; ADF content showed significant difference (P <0.05).
