机械处理对“茶肥1号”种子萌发特性的影响

Effect of Machinery Treatment on the Germination Characteristics of the Seed of Green Manure Chafei No.1

以"茶肥1号"种子为试验材料,研究了机械处理对其种子的硬实性、吸水性及其萌发特性的影响。结果表明,机械处理后其种子的硬实率由对照的46.7%降低到0.3%;发芽率、发芽势和发芽指数分别为91.0%、73.0%、10.2,与对照达到极显著差异。机械处理能有效破除"茶肥1号"种子的硬实,提高发芽率,缩短萌发时间。

The effect of machinery treatment on the hardness, water absorption and germination of the seed of green manure Chafei No.1 was studied. The result showed that the seed hardness after machinery treatment lowered from 46.7% to 0.3%, and the germination rate, germination potential and germination index is 91.0%, 73.0% and 10.2 respectively, significantly different from control. As a conclusion, machinery treatment can lower the hardness of the seed of green manure Chafei No.1 effectively, improve its germintation rate and shorten the germintation period.
