Dry 2-4h, for use after grinding at 100-120 DEG C；
（2）Magnetization treatment：
Flyash is ground to 60 mesh hereinafter, sending and handles 4- into the electromagnetism magnetizer that magnetic field intensity is 3000-5000Gs
7s takes out the flyash after magnetization, for use；
（3）Flyash lotion：
It takes the above-mentioned magnetization flyash of 4-5g to be mixed with 40-50 parts of distilled water, 1-2g emulsifier span-80 is added, add 1.5-
2.3g Silane coupling reagent KH-570s, are dispersed with stirring 1.5-3h, and 40-50 DEG C of heat preservation 5-7h obtains functionalization flyash lotion；
（4）Potato starch and water are pressed 1:The ratio of 1-3 be placed in equipped with blender, condenser pipe, thermometer three-necked flask in,
It is gelatinized 2-5h in 65-73 DEG C of constant temperature, is cooled to 25-35 DEG C；
（5）Degree of neutralization is scattered in the acrylic acid solution of 85-95% after above-mentioned gelatinization in potato starch solution, is added above-mentioned
Functionalization flyash lotion is dispersed with stirring 0.5-1h, and initiator ammonium persulfate-sodium sulfite is added, and room temperature disperses 25-40min
Afterwards, the insulation reaction 1.5-3h at 45-60 DEG C is warming up to 75-85 DEG C of heat preservation 2-3h later, after, it is placed in 70-80 DEG C dry
It after drying a few hours in dry case, then is freeze-dried to constant weight, plural gel resin is obtained after crushing.
Wherein, the usage amount of the initiator ammonium persulfate-sodium sulfite is the 0.8-1.2% of acrylic monomers quality.
Wherein, content of the flyash in plural gel resin product is in 8-15%.
Wherein, in the seedling medium further include organic fertilizer, vermiculite, humic acid ingredient, by plural gel resin after crushing
It is mixed with mentioned component.
Compared with prior art, the present invention has the following advantages：
Flyash is first carried out pickling by the present invention, releases surface hydroxyl, is conducive to and silane coupling agent γ-methacryloxy
Propyl trimethoxy silicane reacts, and is modified to flyash and functionalization flyash lotion is prepared, as crosslinking agent, over cure
Sour ammonium-sodium sulfite makees initiator, and using solution polymerization process, it is compound that flyash-grafting acrylic acid with potato starch is prepared
Gel resin, compared to high hydroscopic resin, gel resin internal cross-linked structure prepared by the present invention is even closer, and network structure is micro-
Hole is smaller, and water-absorbing resin rate of water absorption is slower, and when swelling is not easy to expand, and one can be evenly mixed in other matrix, soil etc.
It rises, is conducive to keep seedling medium shape, is conducive to the growth of plant；Magnetization treatment is carried out to flyash in the present invention, generation
Magnetic fields can change the structure and activity of bacterial enzyme in soil or matrix, seedlings root can be promoted to grow, and be conducive to plant children
Seedling is grown.
