| 摘 要： | 研究了青海冷地早熟禾(Poa crymophila cv. Qinghai)在青藏高寒地区的生产性能, 结果表明, 在高寒地区旱作条件下, 青海冷地早熟禾种植当年生长缓慢, 第2和第3年生长迅速, 整个生育期为106～110 d。从开花期到乳熟期生物量增长最快, 进入完熟期后生长缓慢。粗蛋白含量随生育期的推进呈下降趋势, 抽穗期含量最高;粗纤维含量随牧草生育期的推进呈逐渐增高的趋势;粗脂肪、无氮浸出物和粗灰分含量在整个生育期内无明显变化。

| Abstract: | Production of Poa crymophila cv. Qinghai in the alpine region of Qinghai Tibet was studied. In the alpine region without specific irrigation, P.crymophila cv. Qinghai grew very slowly in the first year of planting and faster in second and third years. The growing period was 106～110 days. P.crymophila cv. grew very fast from the flowering stage to the milky maturity stage and grew very slowly in the ripe stage. Crude protein content decreased with plant growth with the highest content in heading stage. Crude fiber content increased gradually with plant growth. Crude fat, nitrogen free extract and crude ash content have no significant change during the whole productive period. |
