摘　　要：对柱花草(Stylosanthes guianensis)与坚尼草(Panicum maximum CIAT 9)2种热带牧草在旱季进行人工灌溉后刈割,测定灌溉和不灌溉对生物量的影响。分析了2种热带牧草在人工灌溉条件下生物量的变化,结果表明,在人工灌溉条件下生长的2种热带牧草,生长速率快,刈割周期短,其产量和营养价值也有所不同。坚尼草在灌溉条件下其鲜生物量为不灌溉的1.4倍,生长周期缩短34%;柱花草在灌溉条件下其鲜生物量为不灌溉的1.06倍,生长周期缩短27%。An experiment was conducted to determine the effect of irrigation on biomass and quality of Stylosanthes guianensis and Panicum maximum during dry season.The results of this study showed that the irrigation encouraged the S.guianensis and P.maximum to quickly grow,shorten the cutting interval period,and increased the yield.The fresh biomass of P.maximum at irrigation condition was 1.4 times of CK,and the growth period reduced by 34%.The fresh biomass of S.guianensis at irrigation condition was 1.06 times of CK,and the growth period reduced by 27%.
