杂种朱顶红鳞片扦插繁殖技术研究

杂种朱顶红单鳞片扦插只在鳞片远轴面产生突起,不形成小仔球;双鳞片扦插能在内外鳞片的连结处形成小仔球,其中以外部位置,外鳞片厚、内鳞片薄类型生成的小仔球数多,且生根数多;6月份扦插比 4月份有利于小仔球的发育;湿度为 60 %～ 80 %的基质比湿度为 2 0 %～40 %的基质有利于小仔球的发育

The Study on the Technique of Scale Cutting of Hippeastrum Hybridum

In the propagation of Hippeastrum hybridum, only protuberance initiation occurred on the abaxial surface of the scale while using single scale cutting,but no bulblets formed.In twin-scale cutting,the bulblets were produced from the connection part between the outer and the inner xcale.Cuttings from the outer position of the parent bulbs,or cuttings composed of a thicker outer scale and a thin inner scale initiated the most bulblets,at the same time the bulblet's root number was the most.In the process of bulblets formation,cutting propagation in June was better than in April.60%～80% media humidity was more proper than 20%～40% media humidity.
