摘要
选用有特色花、叶且市场潜力大的3种西洋杜鹃与比利时杜鹃进行花期调控比较,探索不同温度、光强度、药物处理对它们花期的影响,结果表明,塑料薄膜保温防霜有利促花,与不保温处理花期有明显差异,可提高1个月;遮光可推迟开花时间;用质量分数1 000×10-6"九二○"+0.1%叶面宝促花效果明显,花径可增加15%～20%。
Three kinds of Rhododendron hybridum with features flowers and leaves and large market potential were selected to conduct comparison on flowering control;different temperature, light intensity and dosing treatment on the effect of their flowering period were explored. Result shows that ： insulation ＆ frost prevention of plastic film ,which are favorable to pro- mote blossom, have significant differences compared with that without insulation ;it can be flowered a month early ; shading can delay flowering time;promoting-flower effect with the mass fraction of 1 000 × 10-6 Jiurling ＋0.1% Yemianbao are significant;flower diameter can increase by 15%-20%.
