- 摘要:
- 以‘金奖’一品红栽培品种为试验材料，研究了多效唑（PP333）与遮光处理对盆栽一品红生长及花期的影响。结果表明：与喷清水对照相比，叶面喷洒PP333溶液对一品红植株的株高、冠幅、分枝数、叶片等均有明显影响，其节间缩短，株形紧凑，叶色加深，叶面积减小，其最适宜浓度范围在15~30 mg/L。遮光处理提前了一品红的花期，其转色期和花期比自然光照提前约2个月。
- Abstract:
- Using Euphorbia pulcherrima Willd ‘Gold Medal’ as the material，the effects of PP333 and shading on the growth and flowering of Euphorbia pulcherrima Willd were studied.The results showed that compared with water treatment，foliar spraying PP333 had obvious influence on the plant height，canopysize，the branches and the leaves of Euphorbia pulcherrima Willd，plant height and internode were more shorter，leaves color were more deeper，the ornamental vaule were better too.The most suitable concentration of PP333 ranged from 15 to 30 mg/L.Flower coloring and flowering phase were two months earlier under shading treatmax than natural illumination.
