Embodiment 1

[0019] The organic fertilizer is fermented once. After high-temperature fermentation, the material has a pH value of 8 on the 15th day and enters the aging stage. When the aging reaches the 22nd day, the moisture is lower than 40%, and the temperature is lower than 45°C. Check its moisture and temperature , pH, when the moisture is less than 30%, the temperature is less than 40°C, and the pH is in the range of 7 to 8.5, the next step is to proceed:

[0020] 1Kg molecular weight is 5000, and active ingredient is the polyaspartic acid solution of 40wt% and is prepared as the diluted 10Kg solution with common tap water, and solution is acidic, and its pH is adjusted to be 8, sprays through the diluted polyaspartic acid solution into 1T In the organic fertilizer, stir while spraying until the moisture increases by 1 percentage point;

[0021] After stirring evenly, it can be packaged after standing and stacking for 1 day.

Embodiment 2

[0023] Ferment the organic fertilizer once. After high-temperature fermentation, the pH of the material is still 6.7 on the 15th day. At this time, add 5Kg of urea and ferment for another 5 days, so that the compost is in an alkaline state, with a pH of 8.3, and enters the aging process. stage;

[0024] During the period from the end of the organic fertilizer aging period to the time before the organic fertilizer is ready to be processed into a finished product, when the moisture content of the organic fertilizer is less than 30%, the temperature is lower than 40°C, and the pH is in the range of 7-8.5, proceed to the next step:

[0025] 1Kg molecular weight is 5000, and active ingredient is the polyaspartic acid solution of 40wt% and is prepared as diluent with common tap water, because tap water is partial acid, the pH of the solution prepared is 6.2, at this moment gradually add potassium hydroxide in a small amount to adjust, Make the pH 8.5, then spray the diluted polyaspa...

Embodiment 3

[0028] The organic fertilizer is fermented once, and after high-temperature fermentation, the pH of the material is 8.2 on the 15th day, and it enters the aging stage;

[0029] During the period from the end of the organic fertilizer aging period to the time before the organic fertilizer is ready to be processed into a finished product, when the moisture content of the organic fertilizer is less than 30%, the temperature is lower than 40°C, and the pH is in the range of 7-8.5, proceed to the next step:

[0030] 5Kg molecular weight is 10000, the active ingredient is the polyaspartic acid solution of 35wt% and is prepared as diluent with common tap water, and potassium hydroxide is added in a small amount gradually to adjust, and pH is 9, sprays again through the diluted polyaspartic acid Put the solution into 1T organic fertilizer, and stir while spraying until the moisture increases by 2 percentage points;

[0031] After stirring evenly, it can be packaged after standing and ...

Abstract

The invention discloses a making method for an organic fertilizer for promoting the nutrient function of crops. The method comprises the steps: performing aerobiotic fermentation on the organic fertilizer, and enabling the pH of the organic fertilizer to be 7-8.5; aging the organic fertilizer after aerobiotic fermentation, when the moisture content of the organic fertilizer is lower than 30%, the temperature is lower than 40 DEG C, and the pH is in a range of 7-8.5, diluting 1-10 Kg of polyaspartic acid with water, regulating the pH to be between 8 and 9, and spraying the polyaspartic acid which is diluted into the organic fertilizer and stirring the sprayed polyaspartic acid and the organic fertilizer to be uniform, so that the moisture content of the organic fertilizer is increased by smaller than or equal to 2%; then standing and piling the organic fertilizer in which the diluted polyaspartic acid is sprayed for at least one day. According to the invention, the polyaspartic acid is added in the production technology of the organic fertilizer, so that the utilization of micro elements contained in the organic fertilizer and the fast-acting property are improved, and the value of the organic fertilizer is promoted.

Description

【Technical field】 [0001] The invention relates to a method for preparing an organic fertilizer for improving the nutrient function of crops, and belongs to the technical field of agricultural fertilizers. 【Background technique】 [0002] Polyaspartic acid is a biomimetic synthetic water-soluble polymer substance, which has the characteristics of phosphorus-free, non-toxic, pollution-free and completely biodegradable. It is an internationally recognized "green chemical". Due to the structural characteristics of polyaspartic acid containing active groups such as peptide bonds and carboxyl groups, it has strong chelating, dispersing, and adsorption functions, and has excellent compatibility. It is widely used in fertilizer synergists and can be used as a fertilizer booster. Efficacy agent is the raw material of polypeptide urea, polypeptide compound fertilizer and controlled-release fertilizer. It can promote the absorption of nutrients by crops such as grain, vegetables, melons...
