preparation example Construction

[0035] The preparation method of the tea special fertilizer of one embodiment, comprises the following steps:

[0036] The raw materials are made into tea special fertilizer, wherein, in terms of mass percentage, the raw materials of tea special fertilizer include: 55% to 75% ammonium nitrate phosphate fertilizer, 1% to 3% ammonium sulfate, 5% to 15% phosphoric acid Monoammonium, 15%-30% potassium sulfate, 1%-5% potassium fulvic acid, 0.5%-2% polyglutamic acid and 0.5%-1% trace element chelating agent. The tea special fertilizer prepared by the preparation method of the tea special fertilizer can improve the yield and quality of tea leaves.

[0037] Further, the raw materials are made into a special fertilizer for tea by adopting a high-tower granulation process. The moisture content of tea special fertilizer prepared by high-tower granulation process is very low, no drying process is required, which greatly saves energy consumption; the percentage of qualified product partic...

Embodiment 1

[0040] The tea special fertilizer of the present embodiment is prepared by the high-tower granulation process of the raw materials. In terms of mass percentage, the raw materials of the tea special fertilizer include: 60% ammonium nitrate phosphate fertilizer, 2% ammonium sulfate, and 8% monoammonium phosphate , 24% of potassium sulfate, 3% of mineral source potassium fulvic acid, 2% of polyglutamic acid and 1% of trace element chelating agent, among them, nitrogen, phosphorus pentoxide and potassium oxide in ammonium nitrate The total mass percentage exceeds 36.0%, the percentage of water-soluble phosphorus in the available phosphorus exceeds 50%, the mass percentage of water is less than 2.5%, the particles with a particle size between 1.00mm and 4.75mm exceed 90%, and the concentration of chloride ions The mass percentage content is less than 3.0%; the mass percentage content of nitrogen in ammonium sulfate exceeds 21%; the mass percentage content of nitrogen in monoammonium...

Embodiment 2

[0042]The tea special fertilizer of the present embodiment is prepared by the high-tower granulation process of the raw materials. In terms of mass percentage, the raw materials of the tea special fertilizer include: 60% ammonium nitrate phosphate fertilizer, 2% ammonium sulfate, and 10% monoammonium phosphate , 23% of potassium sulfate, 3% of mineral source potassium fulvic acid, 1% of polyglutamic acid and 1% of trace element chelating agent, among them, nitrogen, phosphorus pentoxide and potassium oxide in ammonium nitrate The total mass percentage exceeds 36.0%, the percentage of water-soluble phosphorus in the available phosphorus exceeds 50%, the mass percentage of water is less than 2.5%, the particles with a particle size between 1.00mm and 4.75mm exceed 90%, and the concentration of chloride ions The mass percentage content is less than 3.0%; the mass percentage content of nitrogen in ammonium sulfate exceeds 21%; the mass percentage content of nitrogen in monoammonium...

Abstract

The invention relates to fertilizer special for tea and a preparation method of the fertilizer. The fertilizer special for the tea is prepared from the raw materials in percentage by mass: 55%-75% ofammonium nitrate phosphate fertilizer, 1%-3% of ammonium sulfate, 5%-15% of monoammonium phosphate, 15%-30% of potassium sulfate, 1%-5% of fulvic acid potassium salt, 0.5%-2% of polyglutamic acid and0.5%-1% of a microelement chelating agent. Through the fertilizer special for the tea, the yield of the tea can be increased, and the quality of the tea can be improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for tea and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, while the demand for tea is constantly rising, people's requirements for tea quality are also constantly improving. Fertilizer is the nutrient element necessary to provide tea, which can change soil composition, improve soil fertility, and increase soil organic matter. Therefore, rational fertilization plays a decisive role in the growth and development of tea leaves, the promotion of crop metabolism, and the improvement of tea quality and yield per unit area. [0003] However, the compound fertilizers currently on the market cannot meet the nutrition needed by tea trees, resulting in poor quality and low yield of tea leaves. Contents of the invention [0004] Based on this, it is necessary to provide a special fertilizer for tea...
