Problems solved by technology

[0002] Similar organic fertilizers circulating in the market are amino acid organic fertilizers, fulvic acid organic fertilizers, silicon-calcium fertilizers, and calcium-magnesium phosphate fertilizers. Amino acid and fulvic acid organic fertilizers are sprayed and granulated. %, organic matter 20%, amino acid 6-8%, fulvic acid organic fertilizer contains about 4% nitrogen, phosphorus and potassium, organic matter 35-40%, fulvic acid 16-18%, but the weight ratio of a large number of elements is unreasonable. When used, it needs to cooperate with the macroelement fertilizers of nitrogen, phosphorus and potassium and medium and trace elements such as silicon, calcium and magnesium to achieve the purpose of increasing yield and improving quality. is difficult to achieve
Silicon-calcium-magnesium-containing fertilizers are silicon-calcium fertilizers and calcium-magnesium-phosphate fertilizers. Silicon-calcium fertilizers contain 20% silicon and 30% calcium. Calcium-magnesium phosphorus contains 12% phosphorus, 25% silicon, 35% calcium, and 9-10% magnesium, and does not contain organic matter and a large number of elements, mostly in powder form, which is inconvenient to use

The amino acid organic fertilizer is a granule with a nitrogen content of 15% and an organic matter content of 19%. Fulvic acid organic fertilizer is a granule with an organic matter content of 36%. Monoammonium is a powder with a nitrogen content of 11% and a phosphorus content of 42%. The calcium magnesium phosphate fertilizer is a powder, wherein the silicon content is 21%, the calcium content is 31%, the magnesium content is 10%, and the phosphorus content is 12%.

[0023] The components are mixed in proportion, steam granulated, dried in a drum-type hot air oven at 152°C, sieved with a 2-mesh sieve, measured, and packaged.

Embodiment 3

[0025] An organic fertilizer, its components and weight ratio are: 57 parts of amino acid organic fertilizer, 18 parts of fulvic acid organic fertilizer, 3 parts of monoammonium, 20 parts of calcium magnesium phosphate fertilizer, and 2 parts of bentonite. The amino acid organic fertilizer is a granule with a nitrogen content of 16% and an organic matter content of 20%. Fulvic acid organic fertilizer is a granule with an organic matter content of 37%. Monoammonium is a powder with a nitrogen content of 10% and a phosphorus content of 43%. The calcium magnesium phosphate fertilizer is a powder, wherein the silicon content is 23%, the calcium content is 32%, the magnesium content is 10%, and the phosphorus content is 12%.

[0026] The components are mixed in proportion, disc granulated, dried in a drum-type hot air oven at 154°C, sieved through a 2-mesh sieve, measured, and packaged.

Abstract

The invention discloses an organic fertilizer comprising the following components in parts by weight: 55-62 parts of amino acid organic fertilizer, 15-20 parts of fulvic acid organic fertilizer, 1-3 parts of monoammonium phosphate, 20-22 parts of calcium magnesium phosphate fertilizer and 2-3 parts of bentonite. The preparation method of the organic fertilizer comprises the following steps of: mixing all components at ratio, carrying out steam granulation or disk granulation, drying, screening, metering and split charging. The organic fertilizer combines the advantages of the amino acid organic fertilizer, the fulvic acid organic fertilizer and the calcium magnesium phosphate fertilizer, has more scientific weight ratio and is convenient to use. When being used, the organic fertilizer is cooperated with potash fertilizers according to leaf vegetables and fruiting plants, use amount is adjusted, and therefore the purposes of improving yield and improving quality can be realized.
