摘要
通过对东川银合欢与热研1号银合欢的生育期、植物学特征、种子的性质、生长性状及再生性能进行测定。结果表明:东川银合欢在云南年降水量1 000 mm的嵩明地区表现出了较好的生产性能,热研1号银合欢返青比东川银合欢晚7 d,根长、茎粗、叶片大小、单株花数及单株果荚数、果荚大小两品种均差异显著(P<0.05),且东川银合欢优于热研1号。株高、分枝数也差异显著(P<0.05),在各生育期鲜、干草产量大于热研1号。刈割留茬高度50 cm时牧草再生性能最好。
Production performance of growth period, botanical characteristics,seed characteristics, growth character,biomass and regeneration property of Leacaena leucacephal cv. Dongchuan and Leacaena leucacephal cv. Reyan No. 1 were tested. The results showed that Leacaena leucacephal cv. Dongchuan showing better production performance in Songming area of Yurman province at rainfall 1 000 mm condition compared to Leacaena leucacephal cv. Reyan No. 1.
