What are the commonly used formulations of flower preservation agents and the methods of flower maintenance?

1. Aminooxyacetic acid solution

10 × 10-6 gibberellin + 2 × 10-6 kinetin + 9 × 10-4 butyryl callose (containing 85%) + 45 × 10-4 aminooxyacetic acid + 10 × 10-4mtritonX100 (surfactant). Because aminooxyacetic acid can effectively inhibit ethylene synthase, it can prevent the production of ethylene. The ingredients insoluble in water in the above formula can be pre-dissolved with a small amount of alcohol or high spirits.

2. Dimethyl succinase hydrazine fresh-keeping solution

It is prepared with 2% dimethyl succinyl hydrazide, 1% 8-hydroxyquinoline sulfate, 0.1% calcium nitrate, 5% sucrose and water. Because dimethyl succinyl hydrazide can promote flowers to absorb water and inorganic salts, 8-hydroxyquinoline can kill bacteria effectively, so this fresh-keeping solution has a better fresh-keeping effect.

3. Cornell cut flower preservative

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

4. Wotiehua cut flower preservative

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

5. Fresh-keeping solution for cut rose

30g sucrose / L + 130mg 8-hydroxyquinoline sulfate / L + 200mg CA/ L + 25mg silver nitrate / L.

6. Chrysanthemum cut flower preservative

35g sucrose / liter + 30mg silver nitrate / liter + 75 × 10-6CA.

7. Fresh-keeping solution for cut lily flowers

30 mg sucrose / L + 200 mg 8-hydroxyquinoline sulfate / L.

8. Antistaling solution for cut flowers of goldfish grass

1.5% sucrose + 3 × 10-48-hydroxyquinoline citrate + (100.50) × 10-6 dimethyl succinyl hydrazide.

9. Fresh-keeping solution for cut daffodils

60g sucrose / L + 250mg 8-hydroxyquinoline sulfate / L + 70mg CCC/ L + 50mg silver nitrate / L.

10. Citric acid solution

Add 0.4g citric acid to 1000 ml of water.

11. Sucrose solution

(1) 5g sucrose / L + 0.25g (NH4) 2Fe (SO4) 2.6H2O/ L + 50mg vitamin C / L + 50mg Na2B4O7.10H2O/ L + 1g Agar / L. Because Agar can make the fresh-keeping solution form gel, the fresh-keeping solution will not flow out, so the fresh-keeping acid prescription is especially suitable for the preservation of corsage.

(2) 20g sucrose / L + 1g Fe2SO4 ·7H2O / L + 200mg vitamin C / L + 400mg citric acid / L.

(3) 40g sucrose / liter + 10ml alcohol / liter.

(4) 20g sucrose / L + 25mg AgNO3/ L + 200mg citric acid / L.

12. Other

(1) add 3 aspirins to 1 liter of water.

(2) add 10 grams of salt and 10 grams of sucrose to 1 liter of water.

(3) add 40g sucrose, 0.1g boric acid and 0.1g vitamin C to 1 liter of water.
