摘要
本研究旨在通过野生和栽培牧草引种试验，筛选返青早、枯黄晚、青草期长的优良草种（或品种）。结果表明，已筛选出返青早，枯黄晚，青草期比当地鸭茅延长60～88天的草种或品种七个；返青期比当地鸭茅提早16～17天的草种（或品种）四个；五月中旬每亩产草量比当地鸭茅高77．8～455．7千克的草种（或品种）五个。
Based on the field experiment of introduced of wild and cultivated forage species,the study is focused to screen for the fine species or strains with fong growth periced which tum green early in spring and late senescence in fall. The results show that seven of the examined forage species, in those green period is 66-88 days longer than those of the native species of cocksfoot, have been selected. Other four of them prove to be green 16~ 17 days earlier and five to be 77. 8 ~ 455. 7 kg per ha higher in fresh yield than the native species.
