1、关于花后的处理。一般书上都讲花后立刻将花梗剪掉,以免消耗营养。实际上更好的做法是:如不留种,则只需将残花剪掉,保留整个花梗,待花梗完全枯萎后再剪掉,这样的好处是,花梗中的营养会到流到球体内,使球体更好的复壮。如留种,则只需保留一两个足够,其余剪掉,因为一个种荚成熟后可得到80-100粒种子。<img src="attachments/dvbbs/2005-2/2005222201731780.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/2005222201731780.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

2、关于延长花期的方法之一。花刚开放时,去掉雄蕊可延长花期。原因是这样的:花的使命就是为了结果,完成了授粉,花就就会很快衰败而转入结果期。雌蕊有追逐雄蕊的功能,若不能授粉,花则会尽量多开一段时间以争取授粉。

第一点是众多行家的经验之谈,第二点我正在对比试验中。
