Embodiment 1

[0040] (1) Take 40 kg of fresh wheat germ oil residue and put it into a container, add 70 kg of water, adjust the pH value to 7.5, add 0.10 kg of lipase preparation (SUKALip PW15), stir for 3 minutes, and place it at 45°C for 40 hours. Stir once every 3 hours, 3 minutes each time, to obtain lipolytic hydrolysis of wheat germ oil residue;

[0041] (2) Boil the lipolytically hydrolyzed wheat germ oil residue prepared in step (1) for 20 minutes, adjust the pH value to 7.1 after cooling, add 0.8 kg of neutral protease preparation (NE PW50), stir for 5 minutes, and place at 58°C Stand for 2 hours, stir once every half an hour during this period, 2 minutes each time, to obtain protease enzymolysis of wheat germ oil residue, squeeze and filter to obtain liquid and solid two parts;

[0042] (3) Take 90 kg of the solid obtained in step (2), add 10 kg of water, add 0.10 kg of SUKAPhyPW5 phytase preparation, stir well, adjust the pH value to 5.5, and place it at 55°C for 1.5 hours, stirr...

Embodiment 2

[0045] (1) Take 35 kg of fresh wheat germ oil residue and put it into a container, add 60 kg of water, adjust the pH value to 8.0, add 0.08 kg of lipase preparation (a mixture of SUKALip PW15 and SUKALip PW10 in a mass ratio of 1:1), and stir for 4 minutes , placed at 40°C for 38 hours, stirring once every 3 hours, 3 minutes each time, to obtain lipolytic hydrolyzed wheat germ oil residue;

[0046] (2) Boil the lipolytic wheat germ oil residue prepared in step (1) for 15 minutes, adjust the pH value to 6.9 after cooling, add 0.6 kg of neutral protease preparation (NE PW50 and NE PW30 in a mixture of 2:1 mass ratio ), stirred for 4 minutes, placed at 55°C for 2.5 hours, and stirred once every half an hour, 2 minutes each time, to obtain protease enzymatically hydrolyzed wheat germ oil residue, squeeze and filter to obtain two parts: liquid and solid;

[0047] (3) Take 85 kg of the solid obtained in step (2), add 15 kg of water, add 0.08 kg of SUKAPhyPW5 phytase preparation, sti...

Embodiment 3

[0050] (1) Take 30 kg of fresh wheat germ oil residue and put it into a container, add 50 kg of water, adjust the pH value to 8.2, add 0.05 kg of lipase preparation (SUKALip PW10), stir for 2 minutes, and place it at 35°C for 30 hours. Stir once every 3 hours, 3 minutes each time, to obtain lipolytic hydrolysis of wheat germ oil residue;

[0051] (2) Boil the lipolytically hydrolyzed wheat germ oil residue prepared in step (1) for 10 minutes, adjust the pH value to 6.8 after cooling, add 0.4 kg of neutral protease preparation (NE PW50), stir for 3 minutes, and place at 60°C Stand for 3 hours, stir once every half an hour during this period, 2 minutes each time, to obtain protease enzymolysis of wheat germ oil residue, squeeze and filter to obtain two parts: liquid and solid;

[0052] (3) Take 83 kg of the solid obtained in step (2), add 20 kg of water, add 0.05 kg of SUKAPhyPW4 phytase preparation, stir well, adjust the pH value to 4.5, and place it at 60°C for 2.5 hours, stir...

Abstract

The invention relates to a method for preparing a special foliar fertilizer for organic agricultural crops. The method comprises the following steps: by taking wheat germ oil residue as a raw material, firstly, decomposing grease in oil residue by using a lipase preparation, and then decomposing protein by using a protease preparation, so as to produce amino acids and plant active substances; filtering, reserving liquid for later use, and decomposing an organic phosphorus compound in a solid part by using a phytase preparation, so as to generate available phosphorus; filtering and reserving liquid for later use; finally, mixing two parts of liquid, so as to prepare the foliar fertilizer with high amino acid content and abundant available phosphorus nutrition. The foliar fertilizer prepared by the method obtains a good yield-increasing effect by a field experiment.

Description

technical field [0001] The invention relates to a preparation method of a foliar fertilizer, in particular to a preparation method of a special foliar fertilizer for organic agricultural products, and belongs to the technical field of fertilizer production. Background technique [0002] The so-called organic agricultural products refer to those originating from the organic agricultural production system, where the ecological environment quality meets the specified standards, and do not use any harmful chemically synthesized pesticides, chemical fertilizers and other chemical substances in the production process, and are produced in accordance with international organic agricultural production requirements and corresponding standards. Agricultural products that have been processed and certified for human consumption by an independent organic certification body. [0003] Foliar fertilizer is a type of fertilizer that plays an important role in increasing crop production. At p...
