Cymbidium Cultivation and Flower Care Methods
This article introduces some experience in growing the orchid plant Cymbidium, including its cultivation and flower care methods. The site editor will introduce to netizens as follows.
Cymbidium, scientifically known as Gladiolus, is not an orchid but belongs to the Iridaceae family of bulbous plants.
Ecological habits: It is a light-loving long-day plant. In winter cultivation, more light should be provided on cloudy days and it is afraid of cold frost. The suitable growth temperature is 20-25°C during the day and 10-15°C at night. Through the dormant corms, they germinate at temperatures of 4-5°C, and the plants will die if the temperature drops to 0°C in winter. It is not tolerant to waterlogging and dislikes积水. It prefers fertile, well-drained sandy loam soil with a pH value of 5.6-6.5.
1. Characteristics: The plant height is 80-170 cm, with oblate or oval corms that have annular nodes. There are 6-9 sword-shaped leaves. The spikes are umbel-like with 8-24 flowers, and the blooms are large. Gladiolus enjoys cool weather, is not cold-resistant, and dislikes extreme heat. It requires loose, fertile, moist, and well-drained soil. The optimal growth temperature is 20-25°C during the day and 10-15°C at night. Gladiolus is a long-day plant, with 16 hours of sunlight per day being most suitable.
2. Varieties: Gladiolus is a result of multiple generations of hybridization from various sources and there is no universally recognized common name. There are many classification methods for Gladiolus, including spring flowering and summer flowering types based on flowering time; regular and irregular flower arrangements; large, medium, and small flowers based on size; and trumpet, lotus, swallow, etc. based on flower shape.

3. Cultivation Management: ① In production, the main method is to plant corms. In spring, the corms are graded by size and soaked in a mixture of 70% thiophanate-methyl powder at 800 times, benomyl at 1000 times, and captan at 1500 times for 30 minutes, then germinated at 20-25°C for about one week before planting. For severely infected and degenerated varieties, virus-free plantlets can be obtained through apical meristem culture. ② The conventional cultivation of Gladiolus refers to cultivation under natural conditions, generally selecting bulbs with a diameter of 2.5 cm or more. There are two planting methods: ridge planting and bed planting, with a planting depth of 5-10 cm. When the second leaf appears, it is the time for flower bud differentiation, which is very sensitive to environmental factors. If exposed to low temperatures and weak light, the number of "blind flowers" increases. Generally, during land preparation, 6-9 kg of nitrogen, 6-12 kg of phosphorus, and 7-12 kg of potassium are applied per mu. Three topdressings are required during the entire growing season, once when 2-3 leaves are produced, once when the inflorescence emerges from the leaves, and once 15 days after flowering. ③ For forced cultivation of Gladiolus, it is necessary to break the dormancy of the corms first. After harvest, the corms need to be influenced by low temperatures from late autumn to early winter in natural conditions to break dormancy. For forced cultivation, dormancy must be artificially broken, that is, after harvest, the corms are first treated with high temperatures of 35°C for 15-20 days, then with low temperatures of 2-3°C for 20 days, and then planted to grow normally. If flowers are required in January-February, they should be planted in October-November; if planted in December, they will bloom in March-May. That is, from planting to flowering, it takes 100-120 days. The planting spacing for forced cultivation is 15 cm x 15 cm or 25 cm x 7 cm, with 40-60 bulbs planted per square meter. After planting, the daytime temperature should be maintained at 20-25°C and the nighttime temperature at about 15°C. ④ Postponed cultivation can also be used. After harvest, the bulbs are stored in a dry cold storage at 3-5°C and planted in a greenhouse the following July-August, with management similar to that of forced cultivation.
