Embodiment 1
[0028] 1. Modification of corn stalks: at room temperature, crush the corn stalks into powder and pass through 80-200 mesh sieves. Take 10-50 parts by mass of corn stalk powder, 100-200 parts of ethanol, 20-100 parts of 50% NaOH deionized aqueous solution, stir and react at 25-40 degrees for 1-2 hours, then add 15-70 Parts of chloroacetic acid and 45 parts of absolute ethanol, stirred and reacted at 60-80 degrees for 1-2 hours. The reaction solution is neutralized and then filtered, washed and filtered with an ethanol solution with a concentration of 80% to 90%, and dried to obtain the modified corn stalk powder.
[0029] 2. Ultrasonic treatment of corn stalks: Take 2 parts of the modified corn stalk powder in step 1, add 30 to 100 parts of water to fully dissolve it, and use ultrasonic treatment for 4 to 7 minutes to form a modified cellulose solution. At room temperature, 0.1-0.2 parts of cerium ammonium nitrate and 0.225-0.64 parts of HNO3 are dissolved in 5 parts of water...
Embodiment 2
[0033] The preparation method of 1 and 2 is the same as that of Example 1. In the preparation of the nutritional water-absorbing resin, ammonium sulfate: potassium chloride: zinc sulfate: sodium silicate: ammonium ferrous sulfate: boric acid: paclobutrazol=3: 1.27: 0.015: 0.75:0.5:0.025:0.03 solution soaked for 7 to 12 hours, that is, containing 12% of N, containing 12.2% of K, containing 0.06% of Zn, containing 1.3% of Si, containing 1.3% of Fe, containing 0.075% of B, Nutritional water-absorbent resin containing paclobutrazol 0.54%.
[0034]The preparation of the nutritional water-absorbing resin seedling-raising paper of the present invention: the nutritional water-absorbing resin prepared above is evenly sprayed on appropriate paper, then covered with a layer of soft paper, and obtained after drying.
Embodiment 3
[0036] The preparation method of 1 and 2 is the same as that of Example 1, and ammonium sulfate is adjusted in the preparation of nutritional water-absorbing resin: potassium sulfate: zinc sulfate: sodium silicate: ammonium ferrous sulfate: sodium borate: paclobutrazol=3: 1.5: 0.015: 0.75 : 0.5: 0.02: 0.03 After soaking in the solution for 7-12 hours, you can get 11.5% of N, 11.7% of K, 0.058% of Zn, 1.3% of Si, 1.2% of Fe, 0.072% of B, Nutritional water-absorbent resin containing paclobutrazol 0.51%.
[0037] The preparation of the nutritional water-absorbent resin seedling-raising paper of the present invention: the nutritional water-absorbent resin prepared above is uniformly sprayed on appropriate paper, and then covered with a layer of cotton pulp soft paper, and obtained after drying.
