What are the commonly used formulas and care methods for cut flower preservatives?

1. Aminooxyacetic acid solution

10×10-6 gibberellin + 2×10-6 kinetin + 9×10-4 butyryl hydrazide (containing 85%) + 45×10-4 aminooxyacetic acid + 10×10-4 mtritonX100 (surfactant). Because aminooxyacetic acid can effectively inhibit ethylene synthase, it can prevent ethylene production. For the water-insoluble ingredients in the above formula, a small amount of alcohol or strong liquor can be used to dissolve them in advance.

2. Dimethyl succinic acid hydrazide preservative solution

Prepare with 2% dimethyl succinyl hydrazide, 1% 8-hydroxyquinoline sulfate, 0.1% calcium nitrate, 5% sucrose and water. Because dimethyl succinyl hydrazide can promote the absorption of water and inorganic salts by flower materials, and 8-hydroxyquinoline generally and effectively kills bacteria, this preservative solution has a relatively good preservation effect.

3. Cornell cut flower preservative solution

5% sucrose + 2×10-48-hydroxyquinoline sulfate + 5×10-5 silver acetate.

4. Ottawa cut flower preservative solution

10×10-5 isoascorbic acid + 4% sucrose + 5×10-58-hydroxyquinoline sulfate.

5. Rose cut flower preservative solution

30 grams sucrose/liter + 130 milligrams 8-hydroxyquinoline sulfate/liter + 200 milligrams CA/liter + 25 milligrams silver nitrate/liter.

6. Chrysanthemum cut flower preservative solution

35 grams sucrose/liter + 30 milligrams silver nitrate/liter + 75×10-6CA.

7. Lily cut flower preservative solution

30 milligrams sucrose/liter + 200 milligrams 8-hydroxyquinoline sulfate/liter.

8. Snapdragon cut flower preservative solution

1.5% sucrose + 3×10-48-hydroxyquinoline citrate + (10-50)×10-6 dimethyl succinyl hydrazide.

9. Narcissus cut flower preservative solution

60 grams sucrose/liter + 250 milligrams 8-hydroxyquinoline sulfate/liter + 70 milligrams CCC/liter + 50 milligrams silver nitrate/liter.

10. Citric acid solution

Add 0.4 grams citric acid to 1000 milliliters water.

11. Sucrose solution

(1) 5 grams sucrose/liter + 0.25 grams (NH4)2Fe(SO4)2.6H2O/liter + 50 milligrams vitamin C/liter + 50 milligrams Na2B4O7.10H2O/liter + 1 gram agar/liter. Because agar can make the preservative solution form a gel and the preservative solution will not flow out when inverted, this preservative acid formula is especially suitable for corsage preservation.

(2) 20 grams sucrose/liter + 1 gram Fe2SO4·7H2O/liter + 200 milligrams vitamin C/liter + 400 milligrams citric acid/liter.

(3) 40 grams sucrose/liter + 10 milliliters alcohol/liter.

(4) 20 grams sucrose/liter + 25 milligrams AgNO3/liter + 200 milligrams citric acid/liter.

12. Others

(1) Add 3 aspirin tablets to 1 liter water.

(2) Add 10 grams each of table salt and sucrose to 1 liter water.

(3) Add 40-50 grams sucrose, 0.1-0.2 grams boric acid, and 0.1 grams vitamin C to 1 liter water.
