Problems solved by technology

[0003] However, since the granular phosphate fertilizer is mainly made of one raw material, each phosphate fertilizer only contains one of water-soluble phosphorus or citrate-soluble phosphorus. Supply phosphorus nutrients for soil and crops, the effective nutrients are not comprehensive

specific Embodiment approach 1

[0015] The composition of the phosphate fertilizer granule is: 30% of water-soluble phosphorus; 20% of citrate-soluble phosphorus; 10% of insoluble phosphorus; 5% of nitrogen, potassium and medium and micronutrients.

specific Embodiment approach 2

[0016] The composition of the phosphate fertilizer granule is: 25% of water-soluble phosphorus; 15% of citrate-soluble phosphorus; 15% of insoluble phosphorus; 6% of nitrogen, potassium and medium and micronutrients.

specific Embodiment approach 3

[0017] The composition of the phosphate fertilizer granule is: 20% of water-soluble phosphorus; 25% of citrate-soluble phosphorus; 10% of insoluble phosphorus; 7% of nitrogen, potassium and medium and micronutrients.

[0018] The manufacture method of granular phosphate fertilizer of the present invention is: select more than 2 kinds of phosphorus-containing substances for use, then add some other necessary raw materials for crops (such as nitrogen-containing substances, potassium-containing substances, substances containing medium and trace elements), according to a predetermined ratio and process (such as Shotcrete process, agglomerate process and high tower process), mixed and granulated.

[0019] In summary, each particle of the granular phosphate fertilizer of the present invention contains three phosphorus forms: water-soluble phosphorus, citrate-soluble phosphorus and insoluble phosphorus, so it can continuously and evenly provide phosphorus for soil and crops, especiall...

Abstract

The invention relates to a granular phosphate fertilizer. Each granule contains water-soluble phosphorus, citrate-acid-soluble phosphorus and insoluble phosphorus, and thus, the granular phosphate fertilizer can continuously and evenly provide phosphorus for soil and crops, and can especially satisfy the demand for acid soil.

Description

technical field [0001] The invention relates to a phosphate fertilizer, in particular to a granular phosphate fertilizer which can continuously provide phosphorus for soil and crops. Background technique [0002] The granular phosphate fertilizers currently on the market are generally granulated from a phosphorus-containing raw material through physical methods. The raw material phosphate fertilizer mainly contains one of water-soluble phosphorus or citrate-soluble phosphorus. This kind of phosphate fertilizer has the advantages of easy availability of raw materials and low cost advantage. [0003] However, since the granular phosphate fertilizer is mainly made of one raw material, each phosphate fertilizer only contains one of water-soluble phosphorus or citrate-soluble phosphorus. Supply phosphorus nutrition for soil and crops, and effective nutrients are not comprehensive. [0004] In view of this, it is necessary to provide a granular phosphate fertilizer that can solv...
