摘要:

2006~2008年在广西畜牧研究所内对山毛豆(Tephrosia candida)、圆叶决明(Cassia rofundifolia Pers.)、羽叶决明(Chamaecradta nicitans)、圆叶舞草(Codariocalyx gyrans)、184柱花草(Stylosanthes guianensis cv.Reyan No.2)5个豆科牧草品种进行生产性能比较试验。结果表明,圆叶舞草鲜草产量最高(5.06kg/m²),其次是山毛豆(4.69kg/m²),分别比对照品种184柱花草的产量(3.08kg/m²)提高64.28%和52.27%。山毛豆和圆叶舞草适合广西种植,其再生性好,鲜草产量高,粗蛋白质含量高,有望成为广西乃至南方地区新的优质豆科牧草新品种。

Abstract:

Comparing productivity was conducted among Tephrosia candida, Cassia rofundifolia Pers., Chamaecradta nicitans, Codariocalyx gyrans and Stylosanthes guianensis cv.Reyan No.2 from 2006 to 2008 in Guangxi Instiute of Animal Sciences.The results showed that the yield was highest in Codariocalyx gyrans (5.06kg/m²), followed by T.candida (4.69kg/m²), which was 64.28% and 52.27% higher, respectively, than that of the control of S.guianensis cv.No.184 (3.08kg/m²).There was significant difference between the productivity of C.gyrans and that of the control one. In conclusion, the reproducibility, fresh yield and crude protein of T.candida and C.gyrans were better than others, they were liked by cows, goats and rabbits. Therefore, these two kinds of forages are appropriate to be planted and developed as new kinds of good-quality forages in Guangxi Region and even in southern China.
