摘要
研究了不同光照强度及整枝措施对盆栽新几内亚凤仙生长发育的影响。结果表明:在温度为25～28℃,相对湿度为50%～70%时,1.5万lx的光照强度最适合新几内亚凤仙的生长发育;超过2.5万lx的光照强度会明显降低盆花的商品观赏价值;低于2000lx的光照条件会严重影响新几内亚凤仙的生长发育;盛花期适当降低光照会延长花期。在盆栽幼苗生长期及时摘除花芽、萌蘖和多余侧枝能极显著促进新几内亚凤仙的营养生长,适宜的整形修剪可使其及早形成丰满株型,进而提高其观赏价值及商品价值。
The effect of light intensity and pruning on Impatiens hawkeri was studied in this article. The result showed that intensity of 15 000 lx promoted the growth while intensity of 25 000 lx and 2 000 lx had a adverse effect on Impatiens hawkeri and appropriate pruning measure such as getting rid of unnecessary buds and lateral branches improved the shape of plant,so the commercial value of potted-plant was raised.
