Problems solved by technology

Second, the benefit of producing ammonium bicarbonate is low, and many ammonium bicarbonate enterprises have switched to producing urea or other products
[0012] 1. The nutrient content is single, and long-term application will easily cause nutritional imbalance in fruits and vegetables, resulting in deficiency syndrome;
[0013] 2. Lack of organic matter, if applied alone, it is easy to cause soil compaction and poor soil structure;
[0014] 3. Excessive application of nitrogen fertilizers can easily cause crops to grow excessively, that is, excessive vegetative growth; wheat in Henan Province is lodging due to partial application of nitrogen fertilizers, and the annual production loss is nearly 1 billion kilograms. Rust breaks out in wheat in Sichuan and other places basically every year. In recent years, rice blast sheath blight has become more and more serious, and borer damage has become more and more serious. Partial application of nitrogen fertilizer is one of the important reasons;
[0015] 4. Urea contains a toxic substance called biuret. Long-term, single and continuous application of urea on fruits and vegetables can easily cause biuret poisoning;
[0017] 3. The utilization rate of existing nitrogen fertilizer is very low, ammonium bicarbonate is only about 25%, urea is only about 30%, waste and pollution are very serious
[0020] 4. The types of nitrogen fertilizers currently used directly - urea and ammonium bicarbonate are all single-form nitrogen, which has limitations in the efficacy of crops
At present, the mainstream manufacturing method of ammonium chloride for direct fertilization in the market is an extrusion granulation technology that appeared in the 1950s. It uses a roller extruder for granulation, and the particles are uneven and dusty. Low technical content, high environmental pollution

Abstract

The invention discloses a novel nitrogen fertilizer, which is granular or powdery. The nitrogen fertilizer is characterized in that every 100 parts of the nitrogen fertilizer includes the following raw materials by mass: 6-15 parts of the amide nitrogen, 12-19 parts of ammonium nitrogen, 0.2-1 part of zinc in terms of zinc oxide, 0.5-2 parts of magnesium in terms of magnesium oxide, 0.2-1 part of boron in terms of boron oxide, and 5-15 parts of a sustained release filling material. The nitrogen fertilizer of the invention has the advantages of more reasonable raw material resource allocation, more comprehensive efficacy, lower cost, less loss and waste, environmental protection and energy saving, fills the nitrogen fertilizer vacancy, enriches existing nitrogen fertilizer variety, and provides a more forceful guarantee for agricultural development.

Description

technical field [0001] The invention relates to a nitrogen fertilizer, in particular to a novel nitrogen fertilizer which combines the advantages of various existing nitrogen fertilizers and discards the disadvantages thereof, and belongs to the field of nitrogen fertilizer production. Background technique [0002] At present, the main varieties of nitrogen fertilizer industry in my country are urea, ammonium bicarbonate, ammonium nitrate, ammonium sulfate and ammonium chloride. At present, urea and ammonium bicarbonate are the most used for direct fertilization. Ammonium chloride, ammonium nitrate and ammonium sulfate are mainly used in production Phosphate compound fertilizer is rarely used directly. [0003] The production of nitrogen fertilizer in my country in 2006 is shown in the table below: [0004] [0005] At present, nitrogen fertilizers such as ammonium bicarbonate and urea, which are mainly used directly for fertilization, have exposed many problems during ye...
