Abstract

The intention discloses a nitro-compound fertilizer and a preparation method thereof, and relates to the technical field of agricultural fertilizers, the raw material of the nitro-compound fertilizercomprises 35-65 parts of molten ammonium nitrate, 10-35 parts of a phosphate fertilizer, 10-50 parts of a potash fertilizer and 1-10 parts of a fertilizer stabilizer. The raw materials of the compoundfertilizer are simple and easy to obtain, the nutrient content is high, the stability and uniformity are high, and after granulation, the compound fertilizer has the advantages of being smooth in particle shape, few in broken particles and/or balanced in particles.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a nitro compound fertilizer and a preparation method thereof. Background technique [0002] Nitro compound fertilizer is a new type of fertilizer with high efficiency and environmental protection. With the modification of ammonium nitrate for agricultural use, the research and development of nitro compound fertilizer production technology has been continuously developed. [0003] Nitro compound fertilizer is safe and reliable, easy to use, good environmental performance, high nutrient content, contains nitrogen, phosphorus, potassium and other nutrients needed for crop growth, balanced nutrients, high content of active ingredients, easily soluble in water. [0004] At present, the problem of nitro compound fertilizers is that it is easy to form unstable phenomena such as fertilizer agglomeration and pulverization during storage, which will not only cause serious...
