specific Embodiment approach 1
[0005] Specific embodiment 1: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, prepare 500ml of acrylamide aqueous solution with a weight concentration of 50%, and 500ml of a weight concentration of 40% sodium acrylate solution; b , two kinds of monomer solution are packed in the plastic container, then add the NN'-methylenebisacrylamide 4ml, 2.5g disodium ethylenediamine tetraacetate, 2g K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 2.5KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. This embodiment is suitable for coating the seeds of crops such as corn, wheat, and rice.
specific Embodiment approach 2
[0006] Specific embodiment 2: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, preparing 500ml of acrylamide aqueous solution with a weight concentration of 60%, and 500ml of a 30% sodium acrylate solution; b 1. Put the two monomer solutions into a plastic container, then add 5ml of NN'-methylenebisacrylamide, 3g of ethylenediaminetetraacetic acid disodium, 2g of K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 3KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. The proportioning of this embodiment is suitable for coating the seeds of crops such as cotton and sugar beet.
specific Embodiment approach 3
[0007] Specific embodiment three: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, prepare 500ml of acrylamide aqueous solution with a weight concentration of 45%, and 500ml of a weight concentration of 40% sodium acrylate solution; b 1. Put the two monomer solutions into a plastic container, then add NN'-methylenebisacrylamide, 3g disodium edetate, 2g K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 4KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. This embodiment is suitable for coating the seeds of crops such as soybeans and peanuts.
