Embodiment 1

[0030] refer to figure 1 As shown, the present invention provides a protein peptide water-soluble fertilizer. The preparation method is as follows: A. Firstly, soybean meal is used as raw material and enzyme is added to prepare soybean protein peptide hydrolyzate. , manganese salts, iron salts, calcium salts, magnesium salts, or one or several trace element salts for chelation reaction, the reaction time is 1.5-2.5 hours, C. Concentrate the reaction product and concentrate it into 40-60 % concentrated solution, D, add one or more of urea, potassium dihydrogen phosphate, potassium sulfate, ammonium polyphosphate, potassium tripolyphosphate, potassium nitrate and continue to react at 50-60°C for 1-1.5 hours to obtain For liquid products, stir continuously during the reaction.

[0031] Adjust the content of microelements and macroelements according to the types of crops, the period of fertilizer application and the method of fertilization.

[0032] The preparation method of the...

Embodiment 2

[0035] The difference between this example and Example 1 is that the concentrated solution in step C is spray-dried at 230-250°C to form soybean protein peptide powder, and soybean protein peptide powder is added to the double-helix mixer , urea, potassium dihydrogen phosphate, potassium sulfate, ammonium polyphosphate, potassium tripolyphosphate, and potassium nitrate (select the type and adjust the addition amount according to the crop type, application period and application method), start stirring 5-10min, mix evenly to get a solid product.

Embodiment 3

[0037] Taking the protein peptide water-soluble fertilizer applied to the growth and development period of leafy vegetables as an example, in step B, 4% zinc salt and 5% iron salt are added by mass fraction, concentrated and then spray-dried to form soybean protein peptide powder. Add soybean protein peptide powder with a mass fraction of 58%, 36% urea, and 6% potassium dihydrogen phosphate into the double-helix mixer. During the reaction process, keep stirring to keep the temperature at 50-60°C.

Abstract

The invention provides water-soluble protein peptide fertilizer. A preparation method of the water-soluble protein peptide fertilizer comprises the steps that A, firstly, bean pulp is selected as raw materials, enzyme is added for preparing soybean protein peptide hydrolysate, then the temperature is reduced to 50 DEG C to 60 DEG C after warming and enzyme deactivation; B, one or more of zinc salt, manganese salt, ferric salt, calcium salt and magnesium salt of medium trace elements are added for a chelation reaction, and the reaction time ranges from 1.5 hours to 2.5 hours; C, reaction products are concentrated into a concentrated solution of 40% to 60%; D, one or more of nitrogenous fertilizer, phosphatic fertilizer and potash fertilizer are added, the reaction continues to be carried out for 1-1.5 hours at the temperature of 50 DEG C to 60 DEG C, and a liquid product is obtained. The water-soluble protein peptide fertilizer is mainly composed of various elements and protein peptide, and protein peptide and the various medium trace elements are chelated, so that nutritional ingredients are not likely to run off or be fixed by soil; the utilization rate can be increased, the nutrition-allocated proportion is more comprehensive, the fertilizer efficiency is fast and lasting, the soil and surrounding environment cannot be damaged, and agro-ecological balance can be maintained.

Description

technical field [0001] The invention relates to the field of fertilizer production and processing, in particular to a protein peptide water-soluble fertilizer. Background technique [0002] Protein peptide is a pure natural nutrient extracted from plants, and it is also an important part of human cells. It is mainly composed of 2-10 amino acids, and its molecular weight is below 3000. Peptides are products of protein hydrolysis. Since the molecular weight of peptides is smaller than that of proteins, peptides are easier to absorb than proteins, with better absorption effects and higher utilization rates. Among the existing fertilizers, protease is added to the compound fertilizer to promote the decomposition of protein to form polypeptides, so that the plant root system can better absorb the nutrients in the compound fertilizer, thereby improving the fertilizer utilization rate and promoting plant growth. However, the existing polypeptide fertilizers are greatly affected by...
