Culture and Flower cultivation of Gladiolus

Gladiolus, also known as sword orchid, is not an orchid, but belongs to the bulbous plant of the duck tail family.

Ecological habits: light-loving long-day plants, winter cultivation cloudy days to increase light, afraid of cold. The suitable growth temperature is 20 degrees Celsius in the daytime and 15 degrees Celsius in the night. Through the dormant bulbs, the temperature sprouted at 4 mi 5 degrees Celsius, and the plants froze to death when cultivated at 0 degrees Celsius in winter. Do not tolerate waterlogging and avoid stagnant water in the cultivated land. Like the sandy loam with fertile fertility and good drainage, the ph value is 5.6 and 6.5 is the best.

1. Characteristic characteristic

Plant height 80,170 cm, corm oblate or ovoid, with annular nodes. Leaves 6-9, sword-shaped. Scorpion tail umbels, with 24 flowers, large flowers. Gladiolus like cool, not cold-resistant, afraid of extreme heat, requiring loose, fertile, moist, well-drained soil. The optimum temperature for growth is 20-25 degrees Celsius during the day and 10-15 degrees Celsius at night. Gladiolus is a long-day plant, and the light of 16 hours a day is the most suitable.

two。 Variety

Gladiolus is a multi-source and multi-generation hybrid, but there is no recognized system-species name so far. There are many classification methods of Gladiolus, which can be divided into spring flowers and summer flowers according to florescence, regular and irregular flowers according to flower arrangement, giant flowers, medium flowers and small flowers according to flower size, and can be divided into horn type, lotus type, flying swallow type and so on.

Gladiolus is a light-loving long-day plant, avoid cold, like cool climate in summer, can not tolerate excessive heat, the corm germinates under the condition of 4: 5 ℃, and the growth of 20: 25 ℃ is the best. The nature likes the rich and deep sandy soil, which requires good drainage, so it is not suitable to plant in the place where heavy soil is prone to waterlogging. The summer growth in Northeast and North China is better than that in Guangzhou and Shanghai. In winter in Shanghai, you can safely spend the winter in the open field, while in the north, you need to dig out the bulbs and put them indoors for the winter. How to raise the sword orchid 1. The soil cultivated in sword orchid grows well on the sandy loam with deep, loose and fertile slightly acidic soil (pH value 5.5-6.5), and the soil is required to be moist during the growth period. two。 Sword orchid culture fertilization method sword orchid is a fertilizer-loving flower, attention should be paid to timely fertilization after planting. Generally, the manure and urine of mature people at 4:6 can be applied 3 or 4 times a month. Fertilization should pay attention to not too much nitrogen fertilizer, and appropriate application of phosphorus and potassium fertilizer to enhance flower bud differentiation and bulb nutrition. After flowering, calcium superphosphate extract was used as topdressing to promote the growth and enrichment of new corms. Sword orchid should be fertilized at least three times during the growing period. The first time after the expansion of 2 leaves; the second at the 4-leaf stage; the third after anthesis. It is necessary to apply more phosphorus and potash fertilizer and less nitrogen fertilizer to avoid lodging. After flowering, when the leaves are withered and yellowed at least 3 times after flowering, they should be dried in the sun. Then store it in a low temperature and dry place. 3. The watering method of sword orchid culture is to irrigate the sword orchid every 10 days before emergence, and do not dry after the seedlings come out, otherwise the leaf tip will easily turn yellow. After the appearance of scape, it can not be affected by drought. Yuanyuan in summer should be irrigated once every 4 days. Irrigation should be stopped after flowering to prolong the flowering period.

Sword orchid watering to grasp the weight, too much water is easy to cause root rot, lack of water often cause scape wilting and drooping, and still can not recover after watering and bend into a "zigzag" shape, affecting beauty. 4. The temperature of sword orchid culture requires that sword orchid prefer warm and humid climate, avoid high temperature and heat, and are not resistant to cold. The most suitable temperature for growth is 20-25 ℃. When the soil temperature was higher than 5 ℃ in early spring, the corm could sprout, and the growth was inhibited when the temperature was higher than 35 ℃ in summer. Generally speaking, sword orchid can blossom about 3 months after planting, but the cultivation cycle is greatly affected by the temperature in the growing period. The higher the temperature in the growing period, the shorter the cultivation cycle. For example, when the average temperature in the growing period is 12 ℃, it takes 110 to 120 days from planting to flowering, 90 to 100 days when the average temperature reaches 15 ℃, 70 days to 80 days at 20 ℃, and only 60 days to 70 days when the average temperature reaches 25 ℃. 5. The light of sword orchid culture requires the sword orchid to adapt to the sunny and fully illuminated environment. Sword orchid is a typical long-sunshine plant, which can carry out flower bud differentiation only under the condition of more than 14 hours of light, after flower bud differentiation, short-day light can promote flower bud growth and early flowering. Generally, it takes about 70 to 75 days from bulb planting to flowering, depending on the variety, and a few varieties last more than 80 days.

Editor's conclusion: the above introduces how to raise the sword orchid.
