Introduction and breeding skills of Carthamus tinctorius, a strong girl in flowers

The florescence of Carthamus tinctorius is longer, which can be found in spring, summer and autumn. It is suitable for indoor pot planting in temperate zone, and can be used for flower bed, flower border and courtyard planting in tropical areas. Now let's take a look at the knowledge of safflower.

I. introduction of safflower

Carthamus tinctorius is a perennial bulbous plant of Gesneriaceae with 15~25cm height and orange flowers. It is an excellent flower with leaves and flowers. Saffron is native to tropical America. Like warm, moist and semi-shady environment, avoid bright light. Saffron is not delicate, strong vitality, long flowering period, tropical areas can be used for the layout of flower beds, flower borders and courtyard planting. There are many pots and ornamental plants in temperate zones. Carthamus tinctorius likes warm, moist and semi-shaded environment and avoids bright light; it is not delicate, has strong vitality and has a long flowering period. it can be used to decorate flower beds, flower borders and courtyard planting in tropical areas. There are many pots and ornamental plants in temperate zones. Native to tropical America.

Second, the ecological habits of safflower.

For perennial bulb flowers, like high temperature and humid environment, like high temperature and humidity, should be semi-overcast, avoid strong light. The suitable temperature for growth is 25-28 ℃ in daytime and 15-18 ℃ at night. Fertile, loose, well-drained soil is required. Carthamus tinctorius likes warm, humid and semi-shaded environment, has a wide range of temperature adaptation, and can grow normally within 18-40 ℃. But it is not cold-resistant and the room temperature should not be lower than 15 ℃. The soil is required to be loose, fertile and well drained. Greenhouse cultivation needs about 50% shade in spring, summer and autumn, and no shade in winter. The family can be placed indoors in a bright place near the front window, preferring strong scattered light, but avoiding strong direct sunlight.

Third, the cultivation techniques of safflower.

The pot soil of golden red flower can be made of peat soil or rotten leaf soil plus 1 beat 4 river sand or perlite and a small amount of farm manure at a pH value of 6 to 6.5 and planted in a round pot with a diameter of 10 to 15 meters. This plant has a wide range of temperature adaptation and can grow normally within 18-40 ℃, so it can be cultivated in a wide range, but it is not cold-tolerant, so it must be kept at room temperature not less than 15 ℃, otherwise the plant will dormancy, the leaves will turn yellow and fall off, and stop growing. Sharp changes in temperature are taboo. The whole growing season should ensure that the basin soil is moist but not stagnant, otherwise the roots will rot and prevent stagnant water in the basin after rain. Avoid drought, basin topsoil about 1 meter dry can be watered, every time to be thoroughly watered. Because the leaf surface is hairy, do not sprinkle water on the leaf surface when watering, otherwise it will cause the leaf to rot. Dormancy begins in late autumn and early winter and should be watered less. Potted plants grow vigorously in spring, summer and autumn, apply 20% cake fertilizer and water every 2 to 3 weeks, bud to blossom, and apply 1% potassium dihydrogen phosphate once a week. Fertilization should be stopped in winter. The air humidity is kept at 70%-90% and shaded by 50%-80%. Too strong light will burn the leaf surface, while too low light will make the plant grow too long and affect flowering. A warm and humid environment is very important for the growth of saffron, which grows vigorously and blossoms continuously at a temperature of 15 ℃ to 35 ℃. Carthamus tinctorius is a perennial evergreen herbaceous flower of Gesneriaceae, which is native to tropical America. The stem is erect, after growing up, there are underground tubers, the stems and leaves are succulent, the potted plants are 35 cm high, the leaves are larger, 15 cm long, opposite, densely coarsely hairy, wrinkled, red-green and bright. Inflorescences axillary, flowers small, golden yellow, with red stripes or spots inside, fiery red clusters of calyx on inflorescences. Golden flowers, fiery red calyx, form a sharp contrast, very good-looking. There are also big-leaf saffron in the same genus. The basin soil is made of peat, rotten leaf soil and 1/4 river sand or perlite and farm manure. The pH value is 6 to 6.5. it is planted in a round basin with a diameter of 10 to 15 meters. It likes semi-shade environment, the greenhouse cultivation should be shaded by about 50% in spring and summer, full light in winter, suitable growth temperature 20 ℃ to 30 ℃, overwintering temperature 13 ℃ to 16 ℃. Exuberant growing season like adequate moisture, to often keep the basin soil moist, basin topsoil about 1 meter dry can be watered, each time to be thoroughly watered. Basin soil permeability must be good, not stagnant water, otherwise it will rot roots, after rain to prevent stagnant water in the basin. Because the leaf surface is hairy, do not sprinkle water on the leaf surface when watering, otherwise it will cause the leaf to rot. Dormancy begins in late autumn and early winter and should be watered less. When potted plants grow vigorously, 20% cake fertilizer and water are applied every 2 to 3 weeks, budding to flowering, and 1% potassium dihydrogen phosphate once a week.

Above is the knowledge of Carthamus tinctorius. I hope I can help you.
