在贵州省境内不同生态环境条件下采集的32属87种优良野(逸)生禾本科牧草,经种植观察,于1992~1996年对升圃的19份材料在栽培条件下经过几代种子繁殖和人工选择,各个材料的开花期,种子成熟期等性状渐趋一致,并基本稳定。再生能力强,叶量增多。鲜草产量在34t/ha~87t/ha范围内。种子产量85kg/ha~2816kg/ha。拔节期粗蛋白质含量8.83%~18.93%。
A total of 87 species of wild (grass) grasses were collected from 32 genera under different ecological environment in Guizhou Province. After planting and observation, 19 varieties of materials from Shengpu were propagated through several generations under cultivation conditions from 1992 to 1996 And artificial selection, the flowering of various materials, seed maturity and other traits become consistent, and basically stable. Regeneration ability, increased leaf volume. Fresh grass yield in 34t / ha ~ 87t / ha range. Seed yield 85kg / ha ~ 2816kg / ha. Jointing crude protein content of 8.83% ~ 18.93%.
