The hair color of Guolan

The coloring technique is a technique that uses reasonable cultivation methods and some special management to give full play to the color of Chinese orchid flowers. In the cultivation of Chinese blue flowers, it is often found that the color of the flower fades year after year, so people try some methods to make the flower color show fully. For example, the reproductive wood can be replaced or irrigated with ash water after budding to neutralize the acidity of reproductive wood in the basin. Practice has proved that the discoloration of colored flowers is related to the acidity of reproductive wood, and neutral reproductive wood is beneficial to the development of flower color. In the practice of cultivating orchids, it is also found that flower color is related to light, so various methods are used to adjust the light, and even the principle of color filter is used to cover the buds of colored flowers with casing of various colors, the actual effect is very obvious. Filter some colors in the sunlight, which is beneficial to the full expression of flowers and colors. The temperature is also related to the design and color. For example, maple leaves are particularly bright red by frost. After a reasonable period of low temperature, the color of Chinese blue flowers will be particularly abundant. Therefore, the reasonable adjustment of the temperature during the pregnant period is one of the chromogenic techniques. (Ding Yongkang's "three hundred questions on Chinese Orchid Art")
