The top-dressing fertilizer is a fertilization method in which the dilution of chemical fertilizers or trace elements is sprayed on the leaves and is absorbed by the plants through the leaf stomata. Therefore, it is also called foliar fertilizer.

The advantages of dressing fertilizers outside the roots are: the amount of fertilizer is small, the fertilizer effect is rapid and significant, and the fertilizer is not fixed by the soil and is not influenced by the root absorption function.

Inorganic fertilizers are usually sprayed on the foliage, and can be absorbed within 5 hours after spraying. It can be absorbed by 50%-75% within 24 hours, and the fertilizer effect lasts 7-10 days. Therefore, it is appropriate to spray the fertilizer 7-10 days out of the root. .

In addition to the flowering period, the extra-root topdressing can be carried out at other times, but the extra-root dressing is usually performed when the flowering wood grows vigorously or lacks certain elements.
