Abstract

The invention discloses a nanocarbon organic nitrogen fertilizer. The nanocarbon organic nitrogen fertilizer is prepared from the components with proper parts by weight: urea, ammonium sulfate, hair, palygorskite, a mixed solution of mercapto silane and methacrylate acyloxy silane, a mixture of a boric fertilizer and a zinc fertilizer, ferrous sulfate, rhizobia, azotobacter chroococcum, nano carbon, rhizome curculiginis, golden larch bark, sophora flavescens, ligninase, plant ashes, catalase, animal dung and powdery EDTA (Ethylene Diamine Tetraacetic Acid) chelated manganese, wherein the weight ratio of boric fertilizer to zinc fertilizer in the mixture is 1:0.5, Si molar ratio of the mercapto silane and methacrylate acyloxy silane in the mixed solution is 1:1, and the concentration of the mixed solution is 1.5-1.8 percent. By adopting the nanocarbon organic nitrogen fertilizer, acid hydrolysis head is adopted to generate amino acid, and then secondary and trace elements are chelated and effectively utilized. The nanocarbon organic nitrogen fertilizer is suitable for crops such as wheat, rice, corns, soybeans, oilseed rapes and the like, and the cold, drought and pest resistance of the crops can be strengthened; and when the nanocarbon organic nitrogen fertilizer is used for cotton crops, the fiber tension and strength can be strengthened, the yield is remarkably increased, and the quality is remarkably improved.

Description

technical field [0001] The invention relates to an organic fertilizer in agriculture, in particular to a nanometer carbon organic nitrogen fertilizer. Background technique [0002] Since the reform and opening up, my country's agricultural production has made great progress. However, the long-term application of chemical fertilizers has brought serious negative problems such as soil structure damage, water pollution, fertilizer utilization rate decline, and agricultural product quality degradation. At present, my country's food safety situation is still severe, and the source pollution of agricultural products ranks first. Soil is the supplier of nutrients, and the soil is also the storage agent of nutrients, which cannot be replaced by other substances. Regulating soil, improving soil, nourishing soil, restoring soil vitality, showing the natural qualities of soil, is the key to food safety, human civilization and development. The only way for scientific development. In t...
