| 摘 要： | 不同生育年龄山野豌豆地上生物量与粗蛋白含量动态变化的研究结果表明,1龄山野豌豆由于其生育期短,生长缓慢,生物量低,所以基本没有利用价值;与此相对,2龄和3龄山野豌豆则有较高的利用价值。3龄山野豌豆与2龄山野豌豆相比,由于其地上生物量和中后期粗蛋白含量具有明显的优势,所以利用价值高于2龄山野豌豆。在整个生长季节内,不同年龄山野豌豆植株地上生物量的积累呈S曲线变化形式;茎叶比均表现出递增的趋势,而粗蛋白含量则表现为递减的趋势。

| Abstract: | Compared the over-ground biomass and CP content of Vicia.amoena in different generative ages, the results showed that because of its short bearing, slow growth speed and low biomass, annual Vicia amoena has few value in use. Biennial and triennium Vicia amoena have more value in use than annual. Compared with biennial, predominance in over-ground biomass and CP content, triennium Vicia amoena has more value in use. The accumulation of the over-ground biomass in different stages assumed S curve; stem-leaf ratio of different ages increased,but CP content decreased. |
