Organic nutritional energy element of nitrogen fertilizer

Abstract

The invention provides an organic nutritional energy element of a nitrogen fertilizer and belongs to the field of fertilizers, aiming at solving the technical problem that the utilization rate of an existing nitrogen fertilizer is low. The organic nutritional energy element of the nitrogen fertilizer is prepared from the following components in parts by weight: nitrogen, phosphorus pentoxide, potassium oxide, magnesium oxide, copper, iron, manganese, zinc, boron, molybdenum and organic nutritional substances. The applying amount of the nitrogen fertilizer is reduced by about 20%, and the growth of plants can also be good; the yield of crops is increased, and the planting benefits are improved; the incomes of farmers are increased; and chemical fertilizer residues in soil, underground water, air pollution and agricultural products are reduced when a chemical fertilizer is applied. The product is a plant nutritional agent preparation formed by chelating plant microelements and organic matters; the combination of a nitrogen element and soil organic matters is accelerated by mainly reducing the loss of the nitrogen element; and efficient utilization of the nitrogen element is realized through a plurality of manners of improving the content of residual nitrogen in the soil, improving the activity of soil microorganisms, directly improving the utilization of the nitrogen element and the like.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to nitrogen fertilizer organic nutrient active elements. Background technique [0002] With the increase of my country's grain production, the amount of nitrogen fertilizer application is increasing year by year. At present, the annual demand for agricultural nitrogen fertilizer in my country is 52 million tons. With the increase of nitrogen application, the nitrogen in fertilizer absorbed by crops will decrease, the utilization rate of nitrogen fertilizer will decrease, and the residual and loss of nitrogen will increase. There are two ways for crops to absorb nitrogen sources. One is that crops absorb nitrogen from fertilizers; the other is to absorb nitrogen from soil. The utilization rate of nitrogen fertilizer in my country is generally 30-40%, and the residual amount and loss of nitrogen fertilizer is 60-70%. If nitrogen fertilizer is applied on the surface, there will ...
