Embodiment 1
[0024] The preparation method of organic fertilizer is as follows:
[0025] (A) After mixing and stirring wormwood powder 30kg with amino acid powder 10kg, mineral matter 8kg, and high-protein substance 40kg with water, aerobic fermentation was carried out at 55° C. for 5 days to obtain a fermentation mixture;
[0026] (B) After the fermentation mixture is dried and pulverized, 0.05 kg of enzyme preparation is added and stirred evenly, and the finished product is obtained after testing and passing the national standard, wherein the enzyme preparation is an enzyme preparation processed by cellulase.
[0027] Its concrete performance index of the organic fertilizer that detects preparation is as follows: pH value is 6, and the nutrient mass percentage content of nitrogen, phosphorus and potassium element (being nitrogen+phosphorus pentoxide+potassium oxide) is at 7%, organic matter mass percentage The content is 40%, and the moisture mass percentage is 20%.
Embodiment 2
[0029] The preparation method of organic fertilizer is as follows:
[0030] (A) After mixing 40kg of wormwood powder with a mesh particle size of 150 mesh or more, 15kg of amino acid powder, 12kg of minerals, and 55kg of peanut bran with water at room temperature and at a stirring rate of 400rad / min for 30min, the mixture was stirred at 75°C. Under aerobic fermentation for 7 days to obtain a fermentation mixture, wherein the minerals contain metal elements such as Cu, Zn, Mn, B and Fe elements;
[0031] (B) After drying and pulverizing the fermentation mixture, add 0.2 kg of enzyme preparation at room temperature and mix and stir for 20 minutes under the condition of a stirring rate of 400 rad / min, and then obtain the finished product after reaching the national standard through testing, wherein the enzyme preparation is cellulase and An enzyme preparation processed from a mixture of amylases.
[0032] Its concrete performance index of the organic fertilizer that detects prep...
Embodiment 3
[0034] The preparation method of organic fertilizer is as follows:
[0035] (A) 48kg of the mixture of wormwood powder 35kg and amino acid powder 13kg, mineral matter 10kg, peanut bran and fish meal with mesh particle size above 150 mesh was mixed and stirred for 40min under the condition of 500rad / min at normal temperature, and then Aerobic fermentation at 60°C for 6 days to obtain a fermentation mixture, wherein the minerals contain metal elements such as Cu, Zn, Mn, B and Fe elements, and the mass fraction of Cu elements is more than 20% of the total mass of the minerals;
[0036] (B) After drying and pulverizing the fermentation mixture, add 0.1 kg of enzyme preparation at room temperature and mix and stir for 30 minutes at a stirring rate of 500 rad / min. After testing, the finished product is obtained after it meets the national standard and is packaged and put into storage. The preparation is an enzyme preparation processed from a mixture of cellulase, protease and amyla...
