Organic composite nitrogenous fertilizer

Abstract

The invention provides an organic composite nitrogenous fertilizer and relates to a fertilizer. The organic composite nitrogenous fertilizer is characterized by consisting of acyl nitrogen, nitrate nitrogen, ammonium nitrogen, middle trace elements and organic matters, and the mass percentage occupied by the components is shown as follows: 5-15 percent of acyl nitrogen, 5-15 percent of nitrate nitrogen, 55-65 percent of ammonium nitrogen, 5-15 percent of middle trace elements and 5-15 percent of organic matters. The organic composite nitrogenous fertilizer has the beneficial effects that the organic composite nitrogenous fertilizer contains three forms of nitrogen elements, i.e. the nitrate nitrogen, the ammonium nitrogen and the acyl nitrogen; the nitrate nitrogen is quick in adsorption, the leaf photosynthesis is enhanced, the water and fertilizer absorbing capacity of crops is enhanced, and the precocity of the crops is promoted; the ammonium nitrogen and the acyl nitrogen are not easy to lose, the fertilizer efficiency can be prolonged, and no fertilizer removal during the growth period of the corps is ensured; and the organic composite nitrogenous fertilizer exists in a form that organic nutrient fulvic acid potassium is chelated with other middle trace elements, is quickly and fully dissolved and is free from residues, soil hardness can be effectively broken through, a soil aggregate structure is enhanced, the soil is loosened, the air permeability is improved, and the fertilizer and water conservation capacity is improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic compound nitrogen fertilizer. Background technique [0002] When people cultivate plants, they will inevitably take away some nutrients and minerals from the soil. In order to keep the soil fertile, all the mineral nutrients, nitrogen and organic matter taken by plants must be returned to the soil in the form of fertilizers. Fertilizers are generally used to add nutrients to the soil. However, excessive use of chemical fertilizers will damage the structure of the soil, and at the same time, the cultivated plants will be polluted, and most of the chemical fertilizers are relatively inefficient. [0003] Nitrogen fertilizers are chemical fertilizers containing the crop nutrient nitrogen. Elemental nitrogen plays a very important role in crop growth. It is a component of amino acids in plants, a component of protein, and a component of chlorophyll that plays a decisive role in photosynth...
