Abstract
The invention discloses a method for preparing super absorbent resin containing fulvic acid sodium and an MS dry medium. In the process of synthesizing the super absorbent resin, the fulvic acid sodium and the MS dry medium are added, and the super absorbent resin replacing agar to serve as a coagulator of a culture medium, so that the culture medium has proper coagulability and has support function for the cultured plant tissues, nutrient substances are easy to disperse in the absorbent resin, and the nutrient absorption efficiency is improved. Meanwhile, the super absorbent resin has high water absorbing and retaining capacities and reversibility of water absorption and water release, so the plant tissues are facilitated to effectively utilizing water, watering frequency is reduced, and water and labor are saved. The synthesis process is simple; and the product also contains the fulvic acid sodium capable of regulating plant growth, so the product has wider application prospect and higher promotion value.
Description
Technical field
The present invention relates to a kind of High hydrophilous resin and preparation method thereof, especially relate to a kind of preparation method who contains SODLUM FULVATE and dehydration MS substratum High hydrophilous resin, the High hydrophilous resin of the present invention's preparation mainly is applicable to the plant tissue culture aspect.
Background technology
High hydrophilous resin (Super Absorbent Polymer is called for short SAP) is a kind of the have excellent water-absorbent and new functional macromolecule material of water-retentivity, can absorb the water of own wt hundred times or thousands of times and swelling is gel, water can not separated out yet under the pressure of certain limit, can recover its water absorbing properties again after the resin gel thing drying after the suction, thereby important use is all arranged in a lot of fields.As being applied to baby's paper nappy, sanitary napkin, medicament slow release material etc. aspect the medical and health, in industry and construction industry the waterproof etc. that blocks water as oil-water separating agent, siccative, deodorizing composition, cable and tunnel construction, on agricultural as soil improvement, desert afforestation, soil-less culture medium, drought-resistant water-preserving, agriculture chemical slowly-releasing, food and fruit freshness preserving material etc.
The MS substratum is that Murashige and Skoog cultivated design in 1962 for tobacco cell, be characterized in that inorganic salt and ionic concn are higher, has more stable ionic equilibrium system, its nitrate, potassium and ammonium content height, the kind and the ratio of its nutrient are suitable, can satisfy the nutrition and the physiological requirements of vegetable cell, thereby the scope of application are wider, the quick breeding of most plant tissue culture all uses it as substratum, is to use the most general substratum at present.But because the MS substratum in actual use, moisture evaporation speed is fast, brings a lot of inconvenience to tissue culture procedures, has limited the application of MS substratum.
SODLUM FULVATE is a plant growth regulators, have promote cellular plasm to flow, improve cell viability, quicken vine growth and development, short root strong sprout, flower and fruit protecting, raising output, the advantage such as anti-adversity ability that strengthens.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation method who contains SODLUM FULVATE and dehydration MS substratum High hydrophilous resin, this method is to be raw material with vinylformic acid, sodium hydroxide, dehydration MS substratum, SODLUM FULVATE etc., through reasonable proportioning, make by certain technological process and synthesis technique.
Technical scheme of the present invention is as follows: under the ice-water bath cooling and stirring, remove the vinylformic acid of stopper with the sodium hydroxide solution neutralization, obtain vinylformic acid and sodium salt solution thereof, in reactor, add dehydration MS substratum then, SODLUM FULVATE solution, linking agent N, N '-methylene-bisacrylamide solution, initiator potassium persulfate, at room temperature stir 1.0-1.5h, it is mixed, wherein, vinylformic acid and dehydration MS substratum, sodium hydroxide, SODLUM FULVATE, N, N '-methylene-bisacrylamide, the mass ratio of Potassium Persulphate is 1: 0.2-2.5: 0.15-0.35: 0.0002-0.0599: 0.0002-0.0030: 0.0016-0.0089, feed nitrogen afterwards and slowly heating in water-bath, make it react 1h down at 65-85 ℃, continue to heat up, under the condition of boiling water bath heating, be incubated 1.5h again, stop logical nitrogen, be cooled to room temperature, product is taken out, oven dry, pulverize, sieve, promptly get the High hydrophilous resin that contains SODLUM FULVATE and dehydration MS substratum, the suction multiple of product is 530-760 times.
The present invention has the following advantages:
(1) after the High hydrophilous resin suction certain gel-strength is arranged, therefore replace the peptizer of agar with it as substratum, can make substratum reach suitable solidifiability, cultured tissue there is suitable supporting role, can make again and nutritive substance diffusion easily in absorbent resin improve nutrient absorbing efficient.
(2) High hydrophilous resin water-absorbing-retaining ability is strong, also is difficult for dehydration during pressurization, has the reversibility that absorbs water and release water, helps plant tissue and effectively utilizes moisture, reduces the number of times that waters, water saving, saving of labor.
(3) the present invention adopts and add dehydration MS substratum in High hydrophilous resin synthetic process, need only in proportion product be joined the plant tissue culture media that can be made into water-maintaining in distilled water or the tap water during use.
(4) because the growth of different plants requires different acid or alkali environments, so the pH value of plant tissue culture media often becomes because of the plant of cultivating is different.And synthetic High hydrophilous resin of the present invention can use under the acid or alkali environment comparatively widely, and the coagulation result of substratum is unaffected.
(5) the prepared product of the present invention also contain can coordinate plant growth SODLUM FULVATE.
(6) synthesis technique of the present invention is simple, and the no three wastes produce, and help suitability for industrialized production.
