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...

Problems solved by technology

[0005] In order to increase the intake of minerals by poultry, people have mixed inorganic salts and amino acids directly in fertilizers. Although it can supplement the lack of minerals and essential amino acids to a certain extent, the process of storage, transportation and use of minerals Amino acids are easily transformed into insoluble oxides or hydrolyzed into insoluble hydroxides, while amino acids are easily transformed and deteriorated, which greatly reduces their absorption and utilization.
