Problems solved by technology

Urea is a small molecule organic nitrogen fertilizer in terms of chemical composition, and the mechanism of active absorption of nutrients by crop roots is mineral nutrition. After urea is applied to the soil, although urea is easily soluble in the soil solution, it cannot be directly absorbed by the roots of crops in large quantities. Absorption and utilization, so urea needs to be hydrolyzed by microbial urease in the soil to form unstable ammonium carbonate, and then further converted into ammonium ions and carbon dioxide. After the soil, it is easily affected by factors such as soil pH, fertility, temperature and moisture, resulting in a long time for nitrogen nutrient utilization, low utilization rate (generally around 20%-30%), and large loss

Abstract

The invention discloses quick-acting nutrition nitrogenous fertilizer, and relates to the filed of agricultural fertilizer. The quick-acting nutrition nitrogenous fertilizer is prepared by mixing and pelleting 60 to 85 weight parts of ammonium chloride, 2 to 5 weight parts of secondary microelements, 5 to 10 weight parts of urea, 5 to 20 weight parts of ammonium sulfate, 3 to 5 weight parts of silicon fertilizer and 0.02 to 0.04 weight part of plant growth regulator, has the characteristics of full nutrition, high utilization rate, good absorption, quick response and the like, and can be widely used as quick-acting additional fertilizer for planting crops such as paddy rice, vegetables, melons and fruits, flowers and trees and the like.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a quick-acting nutrient nitrogen fertilizer. Background technique [0002] During the growth of crops, a certain amount of nitrogen fertilizer is usually required to promote growth. At present, the nitrogen fertilizer used in agricultural planting is mainly urea. Urea is a small molecule organic nitrogen fertilizer in terms of chemical composition, and the mechanism of active absorption of nutrients by crop roots is mineral nutrition. After urea is applied to the soil, although urea is easily soluble in the soil solution, it cannot be directly absorbed by the roots of crops in large quantities. Absorption and utilization, so urea needs to be hydrolyzed by microbial urease in the soil to form unstable ammonium carbonate, and then further converted into ammonium ions and carbon dioxide. After the soil, it is easily affected by factors such as soil pH, fertility, temperatur...
