根据植物花朵中所含的花青素遇酸变红、遇碱变蓝的原理,笔者对吉祥红山茶花进行了变色试验。即在花蕾吐蕊前夕用优质洗衣粉加90倍的水,冲成溶液,每周1次,喷3次。结果,开花后出现了红色和蓝色两种花朵,但初次试验,色彩不甚理想,有待进一步探索。试验时要注意;1.喷施药液前,花盆和非试验对象的花朵花枝要设法盖住,以免影响其他花朵与土质。2.白色山茶花不必试验,因为白花中不含花青素,小会发生色的变化。
According to plant flowers contain anthocyanins met acid red, case of alkaline turn blue principle, the author of auspicious red camellia chameleon test. That is, on the eve of the bud Tuirui with high-quality detergent plus 90 times the water, washed into solution once a week, spray 3 times. As a result, red and blue flowers appeared after flowering, but the initial test showed that the color was not ideal and needs further exploration. Test should pay attention to; 1. Before spraying the liquid, flower pots and non-test subjects should be covered with flowers to avoid affecting other flowers and soil. 2. White camellia need not test, because white flowers do not contain anthocyanins, small changes will occur color.
