Problems solved by technology

However, due to the influence of crystal shape, composition, structure, surface area, physical and chemical properties and surrounding storage environment, potassium nitrate is very easy to agglomerate, which brings difficulties to storage, transportation and use.
Potassium nitrate is a pseudo-agglomeration, and the agglomeration will break apart when pressure is applied, which brings trouble to the use process.

Abstract

The invention discloses potassium nitrate composite fertilizer. The fertilizer is prepared from, by weight, 60-80 parts of ammonium sulfate, 50-70 parts of triple superphosphate, 40-60 parts of potassium nitrate, 10-20 parts of fulvic acid, 14-28 parts of magnesium nitrate and 6-12 parts of manganese sulfate. According to the potassium nitrate composite fertilizer, through a mode of preparing potassium nitrate into the composite fertilizer, with the help of the interaction effect of other fertilizer components, the caking problem of potassium nitrate is solved, and meanwhile the comprehensivefertilizer effect is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a potassium nitrate compound fertilizer. Background technique [0002] Potassium nitrate is an important fertilizer, containing N13.5% and K2O46%, and there is no residue after application. It is not only a high-quality fertilizer for chlorine-avoiding crops such as tobacco, coffee, tomato, grape, citrus, tea, etc. Potassium nitrate is not only high in potassium content, but also a nitrogen-potassium compound fertilizer with good water solubility, low acidity, and easy absorption by plants. It is suitable for any crop and any season, and has broad-spectrum applicability. However, due to the influence of crystal shape, composition, structure, surface area, physical and chemical properties and surrounding storage environment, potassium nitrate is very easy to agglomerate, which brings difficulties to storage, transportation and use. Potassium nitrate is a pseudo-agglomeration,...
