环境因子对万寿菊开花的影响

通过分析不同营养配比和pH值处理万寿菊水培液的开花情况，试验得出，增施磷肥对万寿菊开花的影响较小；配施磷钾肥主要影响万寿菊的单株花朵数和花型大小；而配施钾肥对万寿菊的花期、单株花朵数和花型大小均有较好的影响。万寿菊开花较适宜的水培条件是pH值6．5，即弱酸到中性的环境。此时万寿菊的花期较长、花型较大、单株花朵数较多，花的颜色也最靓丽。

The Factors of Environment on Flowering of Marigold

In this study, by the experiment of marigold at different hydroponic solution of nutrition ratio and pH, we found that there is less impact between increasing P fertilizer and flowering. The applying of P and K fertilizer principally affected the number and pattern size. K fertilizer had a better impact on flowering, number of flowers and flower size of marigold. In the present study, more suitable for marigold flower hydroponic conditions is pH6.3. At this time, there are a longer flowering, flowers larger flower, and more beautiful color.
