Water soluble quick-acting top dressing specially used for peppers and preparation method thereof

Abstract

The invention discloses a water soluble quick-acting top dressing specially used for peppers. The top dressing comprises the following raw materials in parts by weight: 410-430 parts of ammonium phosphate nitrate, 50-60 parts of monoammonium phosphate, 490-510 parts of potassium sulfate, 20-30 parts of calcium nitrate, 12-22 parts of magnesium sulfate, 2-5 parts of zinc sulfate and 4-8 parts of boric acid. According to the top dressing disclosed by the invention, a nitro-sulfenyl technology, a medium trace element technology and a water soluble fertilizer technology are combined, nutrient elements are scientifically matched according to the growth and a fertilizer requirement law at the period of maturity for picking of the peppers, spray granulation is carried out by a high tower, and the nutrients of granulates are uniform, and therefore, the product and the quality of the peppers can be obviously improved after the top dressing is used in the period of maturity for picking of the peppers.
