6 General requirements
6.1 General requirements
All contents marked shall be clear, firm, in obvious contrast to the base, easy to
6.2 Text
The texts in the marking shall use standard Chinese characters (nutrient names
can be expressed by chemical element symbols or molecular formulas). It may
use synonymous minority characters and foreign characters at the same time,
BUT the foreign characters shall be smaller than the corresponding Chinese
characters and minority characters.
Fertilizer names (including product names) shall not contain false or
exaggerated words and homophonic sounds, including but not limited to high
efficiency, special effects, all-element, multi-element, high-yield, double-effect,

treasure, holy, activity, vitality, strength, activation, stress-resistance, harm-
resistance, high energy, multi-function, full nutrition, green-maintaining, flower-

requirements of this article.
