[0079] In step (I) of the preparation method of the fiber-based water-retaining agent of the present invention, microorganisms are added for the purpose of using microorganisms to microcrystallize cellulose in plant stalks under alkaline conditions.
[0080] Further, in order to microcrystallize the cellulose as much as possible, the Cellulomonas genus in step (I) includes Cellulomonas chrysogenum, Cellulomonas faecalis, Cellulomonas subleukomonas, gelatinous fiber at least one of Cellulomonas spp., Cellulomonas dinitrogenum, Cellulomonas cellulosus and Cellulomonas hygrospores.
[0081] Trichoderma: English name: trichoderma spp; Trichoderma belongs to filamentous fungi.
[0082] Further, in order to microcrystallize the cellulose as much as possible, the Trichoderma in the step (I) includes at least one of Trichoderma multispora, Trichoderma longibrachiatum, Trichoderma spp. and Trichoderma hacinata.
[0083] Further, in order to microcrystallize the cellulose as much as po...
Embodiment 1
[0127] The preparation of embodiment 1 fiber type water retaining agent
[0128] (I) Take 100g of plant straw, crush it, pass it through a 100-mesh sieve, add 70g of water, then add 1.5g of Cellulomonas moist and 0.5g of urea, mix well, and carry out the reaction. Add KOH to adjust the pH to 8. The reaction conditions are React at 10°C for 4 hours, filter to obtain fiber microcrystals;
[0129] (II) Take 100g of fiber microcrystals obtained in step (I), add 2500g of water, 300g of acrylic acid, 5g of KOH, 1g of potassium persulfate and 0.1g of butyl methacrylate, stir well, and carry out the reaction. React for 6h to obtain a gel-like polymer;
[0130] (III) Heat the gel-like polymer obtained in step (II) at 40°C for 3 hours, dry and pulverize to obtain a powdery water-retaining agent.
Embodiment 2
[0131] The preparation of embodiment 2 fiber type water retaining agent
[0132] (I) Take 100g of plant straw, crush it, pass through a 100-mesh sieve, add 60g of water, then add 2g of Cellulomonas xanthogenes and 2g of urea, mix well, and react, add NaOH to adjust the pH to 10, and the reaction condition is 15 React at ℃ for 3.5h, filter to obtain fiber microcrystals;
[0133] (II) Take 100g of fiber crystals obtained in step (I), add 3000g of water, 450g of acrylic acid, 30g of NaOH, 1.3g of sodium persulfate and 0.8g of acrylamide, stir well, and carry out the reaction. The reaction condition is to react at 15°C for 5h , to obtain a gel-like polymer;
[0134] (III) Heat the gel-like polymer obtained in step (II) at 50°C for 0.5h, dry and pulverize to obtain a powdery water-retaining agent.
