Abstract

A calcium fertilizer containing nanometer calcium carbonate, a composite fertilizer containing nanometer calcium carbonate, a preparing method of the composite fertilizer and applications of the calcium fertilizer and the composite fertilizer are disclosed. The composite fertilizer comprises nitrogen, phosphorus and potassium elements and the nanometer calcium carbonate. The composite fertilizer comprises 10-30% by mass of the nitrogen element, 8-30% by mass of the phosphorus element, 5-25% by mass of the potassium element and 0.1-15% by mass of the nanometer calcium carbonate, with the balance being auxiliary materials, and with the sum of mass percentages of all the components being 100%. The fertilizers containing the nanometer calcium carbonate provide a source of a medium element that is calcium. In addition, the stable molecular structure of the nanometer calcium carbonate and a neutral acidity-alkalinity environment provide potential application value for combination with major elements in the fertilizers. The composite fertilizer can be used as a base fertilizer or an additional fertilizer.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a calcium fertilizer containing nano-calcium carbonate, a compound fertilizer and a preparation method and application thereof. Background technique [0002] Calcium carbonate is an inorganic chemical product, usually used as a filler. It has the advantages of low cost and good performance. It is widely used in the fields of rubber, paper, ink, paint and plastics. It is also an important filler in the fertilizer industry. The quality of its performance is closely related to its particle size and dispersion. With the development of nanotechnology, nano-calcium carbonate became a new type of material in the 1980s, which has the advantages of large specific surface area and small particle size. [0003] Chinese invention patent "special fertilizer for spring wheat base fertilizer" (application number 201210267581.6), mentioning the application of 2-5 parts of nano-calc...
