Novel readily available nutritive nitrogenous fertilizer

Abstract

The invention discloses a readily available nutritive nitrogenous fertilizer, and relates to the field of agricultural fertilizers. The novel readily available nutritive nitrogenous fertilizer is prepared by mixing 3 to 5 weight parts of ammonium chloride, 20 to 30 weight parts of urea, 1 to 2 weight parts of microelement, 4 to 6 weight parts of ammonium nitrate, 50 to 65 weight parts of ammonium sulfate, 5 to 7 weight parts of silicon-calcium-magnesium, and 0.01 to 0.03 weight part of plant growth regulator, and extruding and granulating. The novel readily available nutritive nitrogenous fertilizer has the characteristics of comprehensive nutrients, high utilization rate, good absorption, quick response, wide application range and the like, and can be widely used for quick-acting top application of various crops such as tobacco, vegetables, melons and fruits, flowers and trees and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a quick-acting nutritional nitrogen fertilizer. Background technique [0002] Nitrogen nutrient is one of the important elements for crop growth and production. All kinds of crops need to absorb a large amount of nitrogen nutrient from the outside world. The main forms of nitrogen absorbed by plant roots from the soil are ammonium nitrogen (NH+4-N) and nitrate nitrogen (NO-3-N). The low utilization rate of nitrogen fertilizer will not only increase the production cost and reduce the economic benefit, but also will aggravate the pollution to the environment due to the increase of nitrogen lost to nature. Therefore, it is particularly important to increase nitrogen use efficiency and reduce nitrogen loss. During the growth of crops, a certain amount of nitrogen fertilizer is usually required to promote growth. At present, the nitrogen fertilizer used i...

Problems solved by technology

Urea is a small molecule organic nitrogen fertilizer in terms of chemical composition. After urea is applied to the soil, although urea is easily soluble in the soil solution, it cannot be directly absorbed and utilized by the roots of crops in large quantities. Therefore, urea must be hydrolyzed by microbial urease in the soil. Unstable ammonium carbonate is formed, and then further converted into ammonium ions and carbon dioxide. Only when urea is converted into mineral ammonium ions can it be absorbed and utilized by crop roots in large quantities. Therefore, after urea is applied to the soil, it is easily affected by the pH, fertility, and Influenced by factors such as temperature and moisture, the utilization time of nitrogen nutrients is longer, the utilization rate is not high (generally around 20%-30%), and the loss is relatively large
