[0040] The preparation method of calcium fortified SOD urea fertilizer comprises the following steps:
[0041] A, preparation of calcium fortified SOD synergist
[0042] Composite SOD and calcium fortifier are quantitatively mixed in the form of solution to obtain calcium fortified SOD synergist; the mass ratio of composite SOD solution to calcium fortifier solution is 8:1~15:1, preferably 8:1~12: 1;
[0043] The concentration of the composite SOD solution is 30% to 45%, and the concentration of the calcium fortifier solution is 30% to 45%;
[0044] The preparation method of the composite SOD solution is as follows: polysuccinimide is hydrolyzed in the presence of water and potassium hydroxide to obtain a polyaspartate potassium solution, the hydrolysis temperature is 50°C-80°C, and the hydrolysis time is 1.5h-5.0h; then Add acid to the polyaspartic acid potassium solution to adjust the pH to 6.5-7.0, the acid used is any one or a mixture of nitric acid, formic acid, acetic ...
Embodiment 1
[0051] 1. Preparation of raw materials
[0052] 1.1 Preparation of composite SOD solution:
[0053] The polysuccinimide is hydrolyzed in the presence of water and potassium hydroxide, the hydrolysis temperature is 50°C-80°C, and the hydrolysis time is 1.5h-5.0h, to obtain a potassium polyaspartate solution; to the potassium polyaspartate solution Add formic acid to adjust the pH of the system to 6.5 to 7.0; then add manganese chloride to the system, the amount of manganese chloride added is 1 part of manganese chloride per 100 parts by mass of potassium polyaspartate solution, and stir until the chloride Manganese is completely dissolved, and the dissolution temperature of manganese chloride is controlled at 50°C to 80°C; then the solid mass content of the system is adjusted to 30% by adding water or evaporating water to obtain a composite SOD solution;
[0054] After testing, the performance parameters of the resulting composite SOD solution are:
[0055] Active substance c...
Embodiment 2
[0078] The preparation of raw materials and the preparation of calcium-enhanced SOD urea fertilizer in Example 2 are basically the same as in Example 1, the difference being that the dosage of calcium-enhanced SOD synergist is 65Kg / ton of urea.
