Problems solved by technology
Moreover, the phosphate fertilizer produced by chemical reaction (such as reaction with sulfuric acid) needs to consume a large amount of sulfuric acid during production, there is corrosion and loss of equipment, and there is pollutant discharge, and the production cost is relatively high.
The acidity of the phosphate fertilizer obtained in this way is relatively strong, and it will aggravate the acidification of the soil when used in acidic soil.
In addition, the water-soluble phosphate root of phosphate fertilizer is easily fixed after being applied to the soil, and the bioavailability decreases.
[0004] The invention patent "a biological phosphate fertilizer and its manufacturing process (application number 99112552)" uses bacteria to ferment phosphate rock powder to produce phosphate fertilizer. Although it does not belong to the category of chemical fertilizers, the bacteria are living microorganisms and are sensitive to the environment. Both bio-fermentation and biological fermentation require specific temperature and humidity conditions, and the production process is relatively complicated.
The invention patent "Production Method of High-efficiency Phosphate Fertilizer Without Raw Material Acid" (Application No. 00117223) does not require sulfuric acid, but it does not exclude the addition of chemically synthesized substances (such as calcium superphosphate mixed into the finished product), which are used in organic agricultural production will be restricted

Embodiment 1
[0013] Implementation Example 1: Weigh 80-100 mesh phosphate rock powder, 80-100 mesh zeolite powder, and gamma-polyglutamic acid, mix the three in a weight ratio of 100:5-15:1-5, add an appropriate amount of water, and grind Grind it into a homogenate in the machine, and air-dry it to get the finished fertilizer. The finished fertilizers are put into storage directly after ordinary packaging, or the finished fertilizers are put into double-layer pouches with micro holes, sealed and subpackaged, and put into boxes after subpackaging.
Embodiment 2
[0014] Implementation example 2: Weigh 100-200 mesh phosphate rock powder, 100-200 mesh zeolite powder and gamma-polyglutamic acid respectively by weight ratio 100:5~15:1~5, and mix gamma-polyglutamic acid into 100g / L aqueous solution. Pour phosphate rock powder and zeolite powder into a blender and stir. During the stirring process, pour in γ-polyglutamic acid aqueous solution, stir and mix well, pour out, stack for 5-10 days, and air-dry to obtain finished fertilizer. The finished fertilizers are put into storage directly after ordinary packaging, or the finished fertilizers are put into double-layer pouches with micro holes, sealed and subpackaged, and put into boxes after subpackaging.

Abstract
The invention relates to an active natural phosphate fertilizer without chemical synthetics such as sulfate, etc., and a preparation method thereof. According to the demand of the organic agriculture of not using chemical synthetics, natural powdered rock phosphate is taken as raw material, natural zeolite powder and Gamma-polyglutamic acid produced by microbial fermentation are taken as active adsorbents, and then the three are mixed according to a ratio to form a phosphate fertilizer by stirring or grinding. In the process of production, the chemical synthetics is not used or added, equipment investment and loss are low, the active natural phosphate fertilizer has the advantages of simple technique and no waste discharge, which is more convenient for fruit trees to after being packed separately by double-layer pockets with microporous.
Description
(1) Technical field [0001] The invention relates to a method for producing phosphate fertilizer, which belongs to the field of fertilizer production. (2) Background technology [0002] Organic agriculture and green food production advocate the use of natural fertilizers, especially in organic agricultural production, the use of chemically synthesized substances is not allowed, and the use of chemical fertilizers is clearly prohibited in its standards. Phosphate rock powder is a natural mineral phosphorus material, which is advocated in organic agricultural production, but the phosphorus in natural phosphate rock powder is difficult to dissolve in water, the fertilizer efficiency is low, it is difficult to be absorbed and utilized by crop roots, and there is basically no fertilizer effect in calcareous soil . [0003] At present, high-efficiency phosphate fertilizers used in agricultural production are mainly produced through chemical reactions, such as calcium superphosphat...
