Abstract

The invention discloses a multi-element premixed fertilizer, and relates to a premixed fertilizer prepared by compounding multiple elements, belonging to the technical field of agricultural fertilizers. The multi-element premixed fertilizer disclosed by the invention consists of the following raw materials: a decomposed organic fertilizer, ammonium phosphate, a phosphorus nitrate fertilizer, potassium sulfate, a boron-magnesium fertilizer, zinc sulfate and a binder, wherein the ammonium phosphate is selected from monoammonium phosphate and diammonium phosphate, the potassium sulfate and the boron-magnesium fertilizer can be replaced with a magnesium-potassium sulfate fertilizer and borax or boric acid, and the phosphorus nitrate fertilizer can be replaced with calcium nitrate. Through a ratio of reducing nitrogen, increasing phosphorus and supplementing potassium, the multi-element premixed fertilizer disclosed by the invention can enable crops to have sufficient phosphorus through application of a base fertilizer once, a crop fertilization scheme is obtained through split application of a nitrogen fertilizer and a potassium fertilizer, and the multi-element premixed fertilizer hasthe characteristics of comprehensive nutrients, convenience in use and wide application fields.

Description

technical field [0001] The invention relates to a multi-element compound premixed fertilizer, which belongs to the technical field of premixed fertilizers, in particular to a multi-element premixed fertilizer. Background technique [0002] Fertilizer is a material that provides nutrients for crop growth, commonly known as crop grain. There are 16 kinds of nutrients necessary for crop growth, including carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, iron, zinc, manganese, copper, molybdenum, chlorine and other elements. According to the demand of crops for nutrient elements, fertilization in agricultural production in my country is usually applied according to the ratio of nitrogen>phosphorus>potassium. Therefore, the corresponding compound (compound) fertilizers on the market are mostly based on high nitrogen, high potassium and low phosphorus. The main market is dominated by high-nitrogen compound fertilizers. Urea is mos...
