Gladiolus is an herb with a globular root. Flowers can last for about three months. Gladiolus prefers warm and humid environments and cannot grow in too cold an environment. The most suitable temperature for the growth of gladiolus is about 20 degrees Celsius, too high will also cause poor growth of gladiolus. Likes the soil fertility deep sandy soil, likes the illumination, the long time illumination is advantageous to gladiolus flowering.

2. Maintenance skills of gladiolus flowering

(1) Gladiolus likes long-term light and is a typical long-day plant. The 14 hours of light per day before flowering is very conducive to the formation of flower blades and the growth of flower buds, and advance to flowering.

(2) Temperature Gladiolus likes warm environment, the temperature is best around 20 degrees, such temperature is conducive to the formation of flower buds Gladiolus. Gladiolus in winter to enter the dormancy period, so you can use the temperature control, let gladiolus advance into the growth period, which is conducive to gladiolus early flowering.

How do you raise a sword orchid?

Gladiolus flower, scientific name is gladiolus. It's not an orchid. It is a bulbous plant belonging to Iris family. Gladiolus plant height 80~170 cm, green leaves alternate, arranged in two rows, corm oblate or oval, with ring section. How to raise gladiolus? Let's take a look below.

Gladiolus is a typical long-day plant, like sunshine, fertile soil, like cool climate conditions, not cold, fear of extreme heat, warm winter, cool summer climate is the most suitable. Fertile, loose, moist, well-drained soil is required. The critical low temperature for growth is 3℃, 4℃~5℃, the corm can germinate and grow; the suitable temperature for growth is 20℃~25℃ in the day and 10℃~15℃ at night. Generally, bulbs can sprout at 5℃, and the optimal temperature for growth and development is 20~25℃ during the day and 15℃ at night. As long as there are 4 to 5 months in a year suitable for growth in the region, can be cultivated.

In China, it is usually cultivated in spring, flowering in summer and dormant in winter. The dormancy period is generally 30~90 days. Gladiolus is fond of deep, fertile and well-drained sandy loam. It is not suitable for growth in heavy clay soil or low-lying ponding. The soil pH value is 5.6~6.5, and sufficient sunshine is required.

Cultivation and reproduction

Gladiolus is a perennial bulbous plant. Its seed head is oblate, outside the coat brown skin, most of the past by import supply. Some scientific research units in the north have succeeded in retaining seeds and can reproduce themselves, but the quality of flowering season is not ideal enough. According to observation, gladiolus is a typical long-day plant, which requires more than 10 hours of long-day conditions before flowering in order to realize the transformation from vegetative growth to reproductive growth. Nowadays, most of the cut flowers are produced in various places, and the soil is rich and fertile, irrigation and drainage are free, and sowing is carried out.

In production, bulbs are mainly planted, graded according to bulb size in spring, soaked in 800 times solution of 70% thiophanate-methyl powder or 1000 times solution of carbendazim mixed with 1500 times solution of captan for 30 minutes, and then germinated at 20~25℃ for about one week. The virus infection is serious, the degeneration obvious variety, may use the stem tip virus-free to cause the plant to rejuvenate.

Conventional cultivation of gladiolus means cultivation under natural conditions

Generally, seeds with a diameter of more than 2.5 cm are selected. There are two planting methods: ridge planting and ridge planting, planting depth 5~10 cm. Gladiolus is sensitive to environmental factors, such as low temperature and weak light, the number of "blind flowers" increases. Generally, 6~9 kg of nitrogen, 6~12 kg of phosphorus and 7~12 kg of potassium are applied per mu during soil preparation. Three topdressing treatments are needed in the whole growing season, i.e., once when 2~3 leaves are sprouted, once when inflorescences are sprouted from leaves and 15 days after flowering.

You need to break the seed ball dormancy first. After harvesting, dormancy can be broken under natural conditions from late autumn to early winter under the influence of low temperature. To facilitate cultivation, dormancy must be broken artificially, that is, after seed bulb harvest, it should be treated with high temperature of 35℃ for 15~20 days, and then treated with low temperature of 2~3℃ for 20 days, and then transplanted, then it can germinate and grow normally. If it is required to flower in January to February, it will be planted in October to November; if it is planted in December, it will flower in March to May. From planting to flowering, it takes 100 - 120 days. The row spacing of plants for promoting cultivation is 15 cm ×15 cm or 25 cm ×7 cm, and 40~60 seed balls are planted per square meter. After planting, the temperature should be kept at 20~25℃ during the day and about 15℃ at night.

It can also be cultivated later.

After harvesting, the bulbs are stored in a dry refrigerator at 3~5℃, and replanted in a greenhouse in July ~ August of the next year. The management work is the same as that of the forced cultivation.

Gladiolus pest prevention

Gladiolus corm disease is more serious, so the corm disinfection is an important measure, the method is to remove the corm skin, immersed in clean water for 15 minutes, then immersed in 80 times formalin solution for 30 minutes or 0.2% ammonium bromide for 10 minutes, then washed with clean water and planted, high temperature and humidity in summer, easy to suffer from blight, in addition to spraying 1000 times of topazine solution or combined with irrigation, application of 10 grams per square meter, but also pay attention to avoid drooping flowers; If nematodes are found, the bulbs should be dug up and burned. In addition to soil disinfection, rotation must also be carried out. The main pests are two-line slime slugs, which can be sprayed with lime water and ammonia water; lime powder is sprinkled around the garden to prevent them from entering; artificial culling.
