【1】Dwarf flower seedlings

Paclobutrazol In production, different concentrations of paclobutrazol can be applied according to the different needs of potted lily height. When the yellow-flowered lily grows to a plant height of 15-20 cm, 50-100 mgL of paclobutrazol solution (15 mL/piece) is irrigated in the heart, repeated once after 7 days, the plants are significantly dwarfed, the stems are thick, and the leaves are dark green , the flower shape is intact at the flowering stage

【2】Promoting flowering

Gibberellic acid (GA3) The flowering of lily bulbs requires a certain period of low temperature storage. Gibberellic acid treatment was the most effective method to control flowering period. Treating young buds with 40 mg/L gibberellic acid could not only shorten the flowering period, but also make the pedicels elongate and straighten and enhance the ornamental quality.

Chloroquine (CCC) Chromium can make the lily plant compact, the flower stem is strong, the leaves widen and thicken, the leaf length becomes shorter and rounder, and the ornamental quality of the lily is enhanced. 200mg/L Chlormetrodin can make lily buds 4-5d earlier and early flowering 6d. 1000-2000mg/L Chlormetrodin can be used for potted lily.

【3】Preservation of cut flowers

Gibberellic acid (GA3) The treatment of 3% sucrose + 200mg/L 8-hydroxyquinoline citric acid and 10mg/L gibberellic acid in bottled lily can significantly prolong the flowering time of cut lily flowers and delay senescence.

【4】Extend the viewing period of potted flowers

Mepiquat chloride (PIX) The mepiquat chloride treatment significantly advanced the onset time of Lily orientalis. The plant height of Lily orientalis could be reduced by dipping bulb and spraying in growth period, and the flowering period of single plant and group could be prolonged by spraying in bud stage. The optimum concentration was 400 mgL.
