3个菊科饲用牧草产草量及生物学特性初步评价

Preliminary Evaluation on Forage Yield and Biological Characters of Three Forage Varieties in Compositae

在闽南地区对3个菊科饲用牧草品种的物候期、产草量、营养成分、种子产量等方面进行研究,结果表明:各参试品种均能在闽南地区越夏、越冬正常生长,其中串叶松香草整体表现均较优,4次刈青鲜草产量达89204.46 kg/hm2、开花期粗蛋白10.13%、种子产量97.0 g/m2、种子发芽率达86.8%。综合分析得出串叶松香草较适宜在闽南地区推广种植。

The phenological period, forage yield, nutrient content and seed yield of three forage varieties in Compositae were observed. The results were as follows： all varieties lived through the winter and grew normally in south Fujian region. The forage yield and characters of Silphium perfoliatum were the best, its four harvesting fresh forage yield was 89204.46 kg/hm^2, CP at flowering stage was 10. 13%, seed yield was 97.0 g/m^2 and seed germination rate was 86.8% , thus it could be planted widely in the south Fujian region.
