A Complete Analysis of the Key Management Points and Methods for Field-Grown Flowers

The management standard for field-grown flowers is vigorous growth, lush branches and leaves, brilliant colors, novel and beautiful patterns, and a sense of three-dimensionality and artistry.

1. Growth vigor

Good growth vigor, high flowering rate, consistent flowering period, flower size and color should match the biological characteristics of the variety, uniform flower distribution, pure flower color, neat crown width, not less than 20cm, no missing branches or withered leaves, normal leaf color with no adverse conditions, coordinated and beautiful growth, no pests or diseases, breakage, abrasions, crushing damage, cold injury, water damage, pesticide damage, sunscald, spots, fading, lodging, or leggy growth.

2. Pruning and tidying

For field-grown flowers, when the flowers and inflorescences are in the late full-bloom stage, they should be removed promptly, and leaves and branches that hinder the view should also be pruned promptly so as not to affect the ornamental effect.

3. Weeds and loosening the soil

Weeds must be removed frequently, and there must be no obvious weeds taller than the field-grown flowers; when loosening the soil, take care to protect the root system, try not to damage the roots, and the roots must not be exposed.

4. Irrigation and fertilization

Field-grown flowers should be reasonably irrigated and fertilized according to the growth and flowering characteristics of the plants. They should be watered at least once a day, and the watering should be sufficient and thorough; in dry seasons, water once in the morning and once in the evening; generally, organic fertilizer should be added as base fertilizer when changing flowers each time, and phosphorus and potassium fertilizer should be applied as needed according to actual conditions, or fertilizer can be applied by foliar feeding. Chemical fertilizers and organic

fertilizers should be used alternately to prevent soil compaction and fertility decline.

5. Replanting

Missing plants and declining plants must be replanted promptly. The variety and specifications should be consistent with the original variety and specifications to ensure a fine landscape effect. Replanting should be carried out according to planting standards, with sufficient base fertilizer applied and management measures such as watering and maintenance strengthened.

6. Prevention and control of pests and diseases

Do a good job of pest and disease prevention and control in a timely manner, and according to the principle of giving priority to prevention and comprehensive control, detect and handle problems early. When pests and diseases occur, the severely affected area should be controlled below 8%, and it is strictly forbidden to use highly toxic, highly toxic, or high-residue pesticides explicitly prohibited by the state; the use of biological pesticides is advocated.
