- Oct 28, 2016 -

Potassium nitrate

Nitrate-nitrogen containing 13.5%, potassium 46%, is chemically neutral, physiological neutral fertilizer, has good water solubility, long term application, would not lead to soil acidification, applied to fruit trees in young fruit stage to early coloring can promote cell expansion, because it contains nitrate nitrogen, late coloring is not recommended to use, easily lead to turning green.

Potassium dihydrogen phosphate

Phosphorus-containing 52%, potassium 34%, is chemically neutral, physiological neutral fertilizer, good solubility in water. Before and after flowering and can be used for promoting the germination of root and Bud differentiation, provides energy for efflorescence; powder coloring, coloring used can contribute to increase fruit sweetness; fruit picking can promote branch-white, degree of fruit wood.

Potassium sulfate

Potassium 54% in theory, usually 50%; is a chemical intermediate, Physiology-acid fertilizer, has very good water solubility, but the long-term use, can increase the soil acidification, applicable late grape coloring to fruit maturity, fruit powder coloring and increase fruit sweetness.
