What applications does chlormequat chloride have in flower cultivation?

Effects of chlormequat chloride on flowers:

1. Cymbidium sinense: Use a 100 mg/kg solution, and after the leaf buds emerge from the soil by a few centimeters, spray once every 20—30 days, for a total of 3—4 sprays, to inhibit overly rapid leaf growth.

2. Poinsettia: Spray with a 500 mg/L solution to increase branching, or mix a 5—20 mg/kg solution into the soil, that is, mix 1 g of the original chemical into the soil per pot (pot diameter 30 cm); dwarfing is obvious, branching increases, the plant shape is attractive, and it blooms more.

3. Lily: Treat the soil with a 3 mg/kg solution, which can reduce plant height, make the stems thick and strong, the leaves dark green, and the flower shape attractive.

4. Freesia: Soak the corms before sowing in a solution at a concentration of 250 mg/kg, which can reduce plant height and flower stem length.

5. Sago palm (Cycas revoluta): When new leaves curl, spray with a 1—3 mg/kg solution once a week for 3 consecutive sprays, which can dwarf the curled new leaves, make the leaf color deeper green, and keep the length moderate, improving ornamental value. For sago palm bonsai, apply a 2500 mg/kg solution to the leaf stalks, significantly inhibiting leaf growth.

6. Bamboo: To dwarf potted bamboo, a chlormequat chloride solution at a concentration of 100—1000 mg/L can be used; when the bamboo shoots emerge from the soil at about 20 cm, inject 2—3 drops into the bamboo cavity, injecting once every 1—2 nodes, and inject again two days later, to control excessive growth of ornamental bamboo; after treatment, the bamboo height is only 1/5 of that without the chemical.

7. Cineraria: Dilute a 50% aqueous solution 2500 times and water the roots, watering once every half month, and stop after buds appear. This can make the plant dwarfed, thick and strong, and the flowering plants uniform.

8. Calceolaria: When the flower buds are 1.5 cm, spray the leaves with a solution at a concentration of 400 mg/kg, then spray once more 2 weeks later, or spray only once with an 800 mg/kg solution; this can promote flowering, reduce plant height, and improve the plant shape.

9. Cherry tomato: When cultivating ornamental cherry tomatoes, before fruit set, a chlormequat chloride solution at a concentration of 0.5 ml/L can be used to water the potting soil. For determinate early-maturing varieties, the dosage is 100 ml per plant; for indeterminate mid-maturing varieties, the dosage is 150 ml per plant. One week after application, the internodes become shorter, the main stem thick and strong, the leaves dark green, the root system well developed, and the fruiting concentrated, which can significantly improve its ornamental value.

10. Hibiscus: When the new shoots grow to 5—7 cm, spray the leaves with a 100 mg/kg solution; the dwarfing effect is good.
