| 摘 要： | 采用植物性吸水材料对垂穗披碱草(Elymus nutant)和山野豌豆(Vicia amoena)种子进行包衣处理,在模拟高寒草地条件下观察包衣种子的出苗,同时测定包衣混合物的持水力.结果表明,最适条件下两种牧草种子的出苗率分别为86%和88%;在模拟条件下,种子的出苗率分别为38%和24%.经过包衣处理后,种子的出苗...

| Abstract: | Seeds of two forage species were coated with mixtures of hygroscopic and plant-derived polysaccharide gums.Seedling emergence of the coated seeds was examined in a growth chamber to simulate climate in the Plateau.The water conserving capacities of the coating mixtures were tested.This study showed that the emergence of the uncoated seeds of two species were 86% and 88% at the optimal conditions and were 38% and 24% at the simulated conditions,respectively.The emergences of the coated seeds of two species w... |
