摘  要:
通过对供试牧草不同建植期连续3a 的观测记载,从出苗数变化和产量分析的结果表明,温带种(白三叶和鸡脚草)春播(3~5月)长势较差,秋播(9~11)长势较好;热带种(大翼豆和南非马唐)春播较好,秋播较差。以包括植株数月、叶色等级、相对产量、草层高度、覆盖宽度、开花情况、种子相对产量、宿存月数等反映长势状况的综合评价指标和实割产量为子序列,以理想值为母序列应用灰色关联方法进行分析,所得的结论与出苗数变化和产量分析相一致。

摘  要:
The plant number and yield of forage growing in different time were observed and recorded in successivethree years.The results showed that temperate specise(Trifolium repens cv Haifa and Dactyls glomerate cvPorto)sowed grew poor in the spring and that sowed m the autumn grew well.On the contrary,tropical species(Macroptilium atropurpureum cv Siratro and Digitarta smutsi(?) cv Premier Finger grass)grew well sowed in thespring and that soved in the autumn grew poor.The method of grey cot relation analysis was applied by using thesynthetic evaluation indexes such as plants number.colour.relative forage yield.height,width,flowering,relative seeds yield,lodging months and actual yield as sub-sequence,and ideal values as the sequence.The resultwas suitable for the changing of plant number and yield.
