贵州野生禾本科牧草引种驯化试验

The Trials on Naturalized Introduction of Forage Grasses Planting in Guizhou Province

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％。

Under the ecological environment of differentiation within the Province of Guizhou, we have collected the best and better grass spp. in Gramineae, wild-grown as well as those escaped in cultivation, totalling 32 genera and 87 species, through observation in sowing trial, from 1992 to 1996, under seed plot plantation in trial, there were 19 accessions of trial species under the planting condition after seed multiplication and manual selection. Both the flowering and seed maturing stages plus many other biological characteristics appeared to show in unanimous appearance and basical stability; the ability of regrowth showed to be much strong; and the leaf-volume indicated to be much more. The fresh grass yields were recorded in the category ranging from 34 ton/ha to 87 ton/ha, and the seed yields ranging from 85 kg/ha to 2816 kg/ha. And the crude protein contents were estimated in the range from 883 to 18.93%.
