Mineral composite premixing fertilizer and preparation method thereof

Abstract

The present invention discloses a mineral composite premixing fertilizer and a preparation method thereof, relates to a multiple mineral salt component co-existing premixing fertilizer, and belongs to the technical field of premixing fertilizers. The mineral composite premixing fertilizer is prepared from the following raw materials by weight: 80-90% of a manure fertilizer, 0.8-1.5% of ammonium sulfate, 0.8-1.5% of ammonium dihydrogen phosphate, 1.8-3% of quick lime, 1.3-3% of potassium sulfate, 1-2% of plant ash, 1-1.3% of attapulgite powder, and 3-8% of a bacterial fertilizer. According to the present invention, with the slow-release coating technology, the fertilizer granule is subjected to the coating treatment, and the nutrient release rate is controlled according to the balanced fertilizer application principle; the attapulgite powder has the unique crystal structure and the unique properties, such that the attapulgite powder has the good soil improvement effect, and is the fertilizer so as to improve soil; and compared with the organic fertilizer having the same amount, the added attapulgite organic fertilizer has the following advantage that the crop yield is increased by 13.8-18%.

Description

technical field

[0001] The invention relates to a premixed fertilizer in which various mineral salt components coexist, and belongs to the technical field of premixed fertilizers, in particular to a mineral compound premixed fertilizer and a preparation method thereof. Background technique

[0002] Minerals are essential nutrients for the healthy growth of animals. In addition to calcium, magnesium, phosphorus, potassium, and sodium, which can be obtained from animal fertilizers and salt, there are also some trace elements necessary for animal growth, mainly for Mineral elements such as iron, copper, manganese, and zinc are difficult to be supplied in daily food intake, but they have a significant impact on the normal growth and development of animal organisms. The growth of animals is mainly due to the effective increase of protein. The basic unit of building protein is amino acid, but it is difficult for animals to synthesize a few essential amino acids in the body, and it...

Examples

Embodiment 1

[0021] 1. Add water to the collected 87kg of fresh manure to make the water content 50%, add 6kg of bacterial fertilizer after 1 month of composting, and make it again after 1 month of composting. The bacterial fertilizer: the following weight ratio Made of raw materials: 10% of Bacillus subtilis, 10% of Bacillus thermophile, 25% of Bacillus natto, 15% of Bacillus megaterium, 15% of Bacillus jelly-like, 25% of Azotobacter torus;

[0022] Two, the ammonium sulfate 1.5kg, ammonium dihydrogen phosphate 1.5kg, unslaked lime 3kg, potassium sulfate 3kg, plant ash 2kg are obtained after ultrafine grinding, and its particle size range is stand-by after 0.0002mm;

[0023] 3. Granulation: Mix and granulate fermented manure, ammonium sulfate, ammonium dihydrogen phosphate, quicklime, potassium sulfate, and plant ash. The particle size is 2mm. In the attapulgite powder of the mesh sieve; make the powder completely cover the surface of the granular material, and obtain the fertilizer.

Embodiment 2

[0025] 1. Take 90kg of fresh manure, 0.8kg of ammonium sulfate, 0.8kg of ammonium dihydrogen phosphate, 1.8kg of quicklime, 1.3kg of potassium sulfate, 1kg of plant ash, 1kg of attapulgite powder, and 3.3kg of bacterial fertilizer.

[0026] Two, the implementation steps are the same as in Example 1.

Embodiment 3

[0028] 1. Take 85kg of fresh manure, 1.5kg of ammonium sulfate, 1.5kg of ammonium dihydrogen phosphate, 1.8kg of quicklime, 3kg of potassium sulfate, 1.2kg of plant ash, 1kg of attapulgite powder, and 5kg of bacterial fertilizer.
