Example Embodiment
[0031] Example 1
[0032] (1) Add 30.20g acrylamide and 33.91g acrylic acid to the reactor, and then add 55.53g potassium hydroxide solution with a concentration of 30.00% to neutralize the acrylic acid, and maintain the temperature of the reaction solution not to exceed 30°C during the process;
[0033] (2) Add 20.30 g of potassium humate to the solution of step (1), and stir evenly at 20-30°C;
[0034] (3) Add 3.05g of 2.00% ammonium persulfate solution and 1.45g of 2.00% concentration of N,N-methylenebisacrylamide solution to the reactor in turn, and add 380g of deionized to the reaction system Water, stir evenly at 25~35℃;
[0035] (4) Raise the temperature of the reaction solution to 70-80°C for reaction, and stop the reaction when a viscous gel-like product is formed;
[0036] (5) Take out the product, cool to room temperature, cut into small pieces, dry, and pulverize with a pulverizer to obtain a humic acid-based agricultural and forestry water-retaining ecological treatme...
