Abstract
The present invention discloses a kind of method for preparing Tobacco Seed Germination bed using offal; include: step 1: pretreated offal powder, acrylic acid and sodium acrylate neutralizer, acrylamide, initiator and crosslinking agent are mixed; mixed liquor is carried out to ultraviolet 3~25min of light irradiation at room temperature, obtains offal based polyacrylic acid-polyacrylamide composite hydrogel；Step 2: offal based polyacrylic acid-polyacrylamide composite hydrogel being placed in methanol or ethyl alcohol and is impregnated, standing 12~take out afterwards for 24 hours, deionized water is washed 2~3 times; it is placed in Enough Dl water; it is swollen 2~3h, is taken out after being balanced up to water suction, obtains Tobacco Seed Germination bed.Using offal as raw material; acrylic acid and sodium acrylate neutralizer and acrylamide are monomer; using ultraviolet radiation process one-step synthesis offal based polyacrylic acid-polyacrylamide composite hydrogel, it is used as Tobacco Seed Germination bed after prepared composite hydrogel water suction, germination percentage is higher.
Description
Technical field
The present invention relates to germination bed preparation technical fields, more particularly, utilize offal system the present invention relates to a kind of
The method of standby Tobacco Seed Germination bed.
Background technique
For seed germination experiment, having paper bed using more germinating bed at present includes filter paper, germination paper etc., agar bed
Deng.The water holding capacity of paper bed is poor, generally requires and periodically additionally keeps the skin wet, and paper bed generally needs to be placed in different devices
The evaporation rate of its moisture is different in ware, and the amount of moisture required supplementation with is not easy to control, it is difficult to keep the consistency of germination condition；Fine jade
Rouge bed cannot reuse, and price is higher, there is certain limitation to practical application.The super absorbent resin lipid germinating bed of report
Have poly- 2- acrylamido -2- methyl propane sulfonic acid (PAMPS) hydrogel germinating bed (Marvin's is wide et al., 2012,
CNIO2523786A), which needs in N2Under protection, to be reacted 12 hours under the conditions of 60 DEG C, severe reaction conditions, time-consuming,
It is unfavorable for energy conservation and environmental protection.
Summary of the invention
The purpose of the present invention is having designed and developed a kind of method for preparing Tobacco Seed Germination bed using offal, it is with offal
Raw material, acrylic acid and sodium acrylate neutralizer and acrylamide are monomer, utilize ultraviolet radiation process one-step synthesis offal base
Poly acrylic acid-poly acrylamide composite hydrogel is used as Tobacco Seed Germination bed, germination after prepared composite hydrogel water suction
Rate is higher.
Technical solution provided by the invention are as follows:
A method of Tobacco Seed Germination bed is prepared using offal, comprising:
Step 1: pretreated offal powder, monomer mixed solution, initiator and crosslinking agent being mixed, by mixed liquor in room
Temperature is lower to carry out ultraviolet 3~25min of light irradiation, obtains offal based polyacrylic acid-polyacrylamide composite hydrogel；
Step 2: offal based polyacrylic acid-polyacrylamide composite hydrogel being placed in methanol or ethyl alcohol and is impregnated, is stood
12~take out afterwards for 24 hours, deionized water is washed 2~3 times, is placed in Enough Dl water, and 2~3h is swollen, and is taken after balancing up to water suction
Out, Tobacco Seed Germination bed is obtained.
Preferably, the offal based polyacrylic acid-polyacrylamide composite hydrogel is cut to disc and is placed in first
It is impregnated in alcohol or ethyl alcohol.
Preferably, the offal based polyacrylic acid-polyacrylamide composite hydrogel is placed in methanol or ethyl alcohol and is soaked
After bubble, drying is taken out, the drying temperature is 50~100 DEG C, 4~12h of drying time.
Preferably, it by the offal based polyacrylic acid after drying-polyacrylamide compound water congealing rubber pulverizing, is placed in enough
In deionized water, it is swollen 2~3h, up to after water suction balance, filtering is taken out, obtains Tobacco Seed Germination bed.
Preferably, the power of the ultraviolet lamp is 50~500W, and the ultraviolet lamp is 15 at a distance from the mixed liquor
~50cm, right in the monomer mixed solution is 60%~90%, and the quality of the initiator is the monomer mixed solution
The 0.85%~1.25% of gross mass, the quality of the crosslinking agent be the gross mass of the monomer mixed solution 0.05~
0.08%；
Preferably, the preparation of the monomer mixed solution includes:
Acrylic monomers and acrylamide monomer are added dropwise in 20%NaOH solution, it is stirring while adding, it is mixed to obtain monomer
Close liquid；
Wherein, the mass ratio of the acrylic monomers and acrylamide monomer is 5:1, controls the acrylic monomers and third
The ratio of acrylamide monomer and NaOH, so that the degree of neutralization of the monomer mixed solution is 60%~90%.
Preferably, the initiator is the mixing initiation of single photoinitiator or photoinitiator and thermal initiator composition
Agent.
Preferably, the crosslinking agent is N, N- methylene-bisacrylamide
Preferably, the photoinitiator is benzoin and derivative, benzil class, alkylbenzene ketone and benzophenone
