木槿花压花方法的选择

Selection of Embossing Method for Shrubalthea Flower

文章研究了微波压花法和干燥板压花法干燥前后木槿花花瓣色度的变化。试验结果表明:与鲜花相比,2种压花法压制后的花瓣L、a、b值均有所下降。2种压花法处理的花瓣相比,微波压花法和干燥板压花法中L、C值数值相差不大,但a值、b值下降程度有明显差异。通过分析得出:需呈现偏蓝色时,更适合使用微波压花法;需保留更多红色时,更适合使用干燥板压花法。

The changes of petal chromaticity of shrubalthea flower before and after microwave embossing and drying plate embossing were studied.The results showed that compared with flowers,the L,a and b values of petals pressed by the two embossing methods decreased.Compared with the petals treated by the two embossing methods,there was little difference in L and C values between microwave embossing method and dry plate embossing method,but there was significant difference in the decline of a and b values.Through the analysis,it is concluded that the microwave embossing method is more suitable when the required shrubalthea flower are blue;when the shrubalthea flower needs to retain more red,it is more suitable to use the dry plate embossing method.
