Embodiment 1

[0016] Embodiment 1: Dissolve 6.0g sodium hydroxide with 19ml deionized water, under ice-water bath cooling and stirring, neutralize 27g (25.6ml) acrylic acid; Dissolve 0.1g sodium fulvic acid, 0.05g o-nitrate with 25ml deionized water Sodium phenoxide and 0.05g sodium p-nitrophenolate, then add neutralized acrylic acid and its sodium salt solution, 10g dehydrated MS medium, 100mg potassium persulfate, 30mg N, N'-methylenebisacrylamide, at room temperature Stir for 1.0h, then heat slowly under the protection of nitrogen, make it react at 60-80°C for 1h, continue to heat up, keep warm in a boiling water bath for 1.5h, stop nitrogen, cool to room temperature, take out the product, dry, Pulverize and sieve to obtain superabsorbent resin containing compound plant growth regulator and dehydrated MS medium. The water absorption ratio of the product obtained in this example is 570 times.

Embodiment 2

[0017] Embodiment 2: experimental condition is the same as embodiment 1, and difference is to dissolve 0.01g sodium fulvic acid, 0.01g o-nitrophenolate sodium and 0.01g p-nitrophenolate sodium with 25ml deionized water, the water absorption of the product obtained in this embodiment The multiple is 590 times.

Embodiment 3

[0018] Embodiment 3: experimental condition is the same as embodiment 1, and difference is to dissolve 0.1g sodium fulvic acid, 0.1g o-nitrophenolate sodium and 0.1g p-nitrophenolate sodium with 25ml deionized water, the water absorption of the product obtained in this embodiment The multiple is 450 times.

Abstract

The invention discloses a method for preparing a super absorbent resin containing a composite plant growth regulator and a dehydrated Murashige and Skoog's (MS) culture medium. In the method, sodium o-nitrophenolate / sodium p-nitrophenolate, sodium fulvate and the dehydrated MS culture medium are added in the synthesis process of the super absorbent resin, and the super absorbent resin is used in place of agar as a culture medium coagulant for allowing the culture medium to reach a proper coagulability, supporting cultured tissues, allowing the nutrients to disperse in the super absorbent resin easily and improving the absorption rate of nutrients. Meanwhile, because the super absorbent resin has high water absorbing and retaining capacities and water absorbing and releasing reversibility, plant tissues can use water effectively, irrigation times is reduced, and water and labor are saved. The synthesis process is simple, the product contains the composite plant growth regulator, and thus, the resin has a promising application prospect and a high promotion value.

Description

technical field [0001] The present invention relates to a method for preparing a novel superabsorbent resin, in particular to a method for preparing a superabsorbent resin containing a compound plant growth regulator and a dehydrated MS medium. The superabsorbent resin prepared by the present invention is mainly suitable for plant tissue culture . Background technique [0002] Super Absorbent Polymer (SAP) is a new type of functional polymer material with excellent water absorption and water retention. It can absorb water hundreds or thousands of times its own weight and swell into a gel. Water will not precipitate under a certain range of pressure, and the resin gel after water absorption can recover its water absorption performance after drying, so it has important applications in many fields. For example, it is used in baby diapers, women's sanitary napkins, drug slow-release materials, etc. in medicine and hygiene. It is used as an oil-water separator, desiccant, deodor...
