瓜果表面制作成自然字画,可以促进瓜果的销售,增加终济效益。现介绍其字画形成及制作技术。植物瓜果的颜色是由花青素形成的,而果实中花青素的含量又与光照有密切关系。光照强,花青素着色良好;光照弱,花青素形成少,果实着色差;若遮住光照,则花青素无法形成,果皮黄化不能着色。根据果实着色的光生态原理,可以用字画对瓜果表面进行局部遮光,使其不能着色,这样就形成有字
Fruit surface made into a natural calligraphy and painting, can promote the sale of fruits and increase the ultimate benefit. Now introduced the formation and production of calligraphy and painting techniques.

According to the ecological principles of the fruit coloring, the surface of fruits and vegetables can be partially covered with calligraphy and painting so that they can not be colored, thus forming a word
