What should be paid attention to in the maintenance of Carthamus tinctorius

The hairy calyx □ Carthamus tinctorius is named for its open lips. It is a perennial evergreen vine plant with branches hanging down naturally. Flowers born at the ends of branches, flowers growing upward; Corolla lip-shaped, red-orange, milky yellow throat.

The main results are as follows: (1) □ Carthamus tinctorius grows well in bright scattered light environment. The direct sunlight, especially the strong light in summer, is easy to cause the leaves to turn yellow and scorch the leaf tip easily. But if the light is too dark, it is easy to cause poor growth and less flowering. Usually, it is appropriate to hang near the south-facing window □, and hang curtains around noon in summer. The intensity of light can be tested by the change of leaf shape and color. When the light is strong, the leaves turn reddish brown; when the light is weak, the leaves are larger and thinner, and the branches are weak.

(2) during the growth period, the water supply should be adequate, and it is appropriate to keep the basin soil moist frequently, and at the same time, we should often spray water to the branches and leaves and the ground, so as to improve the air humidity and keep the leaves fresh and green. Usually pay attention to uniform water supply, if suddenly more and less, it is easy to cause fallen leaves. Apply thin pancake fertilizer and water every half a month or so during the spring and summer growing season.

(3) cut off the residual pedicels in time after flower fade in order to reduce nutrient consumption. The suitable temperature for growth is 2126 degrees Celsius, which is slightly resistant to cold. The winter room temperature should be kept above 10 degrees Celsius. Change the basin every year or every other year in early spring, combined with pruning to promote the germination of new branches and facilitate more flowering. The cut branches can be used for cutting, cut into each section of about 10 cm long, inserted into the sand bed, watered, covered with plastic film, after about a month can take root and survive.

Introduction to the culture methods and matters needing attention of Carthamus tinctorius Carthamus tinctorius is an excellent hanging plant with high ornamental value in flowers and leaves. As a small indoor foliage and flowering plant, it has beautiful plant shape, luxuriant stems and leaves and colorful flowers, which can be placed in several cases or overhanging. It is a fashionable product for family flower cultivation and has been introduced into China for several years. Lipstick stem drooping up to about 1 meter, lipstick thick green leaves coupled with bright red and strange Corolla, quite loved by people. The flowering of lipstick is mainly in summer. Morphological characteristics of Carthamus tinctorius Carthamus tinctorius is an epiphytic evergreen vine. Epiphytic, often planted in a suspended basket. The stem is about 1 meter long. Flowers paired at the tip of branches, shortly pedicellate, Corolla tube-shaped, bright red. Lipstick flowers and leaves opposite, leaf blade ovate, elliptic or Obovate, leathery and slightly fleshy, long 4.5cm, wide 3cm, entire, midvein obvious, lateral veins hidden, leaf surface dark green, back light green. Flowers axillary or apically clustered. Flowers paired on top of branches, shortly pedicellate, Corolla red to red-orange, ca. 6.5cm. Calyx tube-shaped, black-purple tomentose, until long to about 2cm, Corolla from the calyx mouth grow, tube-shaped, bright red, like lipstick general name. Lipstick stem drooping up to about 1 meter, lipstick thick green leaves coupled with bright red and strange Corolla, quite loved by people. The flowering of lipstick is mainly in summer. The ecological habit of saffron the saffron likes the high temperature, bright, sunny semi-shade environment, although it likes the sun, it can only accept no more than 2-3 hours of direct sunlight every day. It is most suitable for indoor cultivation of saffron to hang about one meter from the south window, keeping the indoor temperature above 24 degrees during the day and 18-21 degrees at night. Potted soil should be loose, well ventilated and always moist. More resistant to cold, but like high temperature environment. Like soil with good drainage. After flowering, you can cut it again, leave 15 cm, and apply thin fertilizer. Cuttage propagation in spring is easy to live. Indoor potted plants or hanging plants for viewing. Beautiful plant shape, luxuriant stems and leaves, colorful flowers. Cultivation techniques of Carthamus tinctorius the cultivation and management of saffron prefers a semi-shady environment with warm and bright light. Lack of light, it is easy to cause branches to grow and not easy to blossom; too strong light, the leaves will become reddish brown. Family cultivation of saffron is most suitable for hanging about 1 meter away from the south window. The pot soil is slightly acidic, and the pot culture soil made of peat soil, sand and vermiculite can be added with appropriate amount of calcium superphosphate. It can also be cultivated with 8 parts of rotten leaf soil mixed with 2 parts of coarse sand, and with mature cow dung and horse dung mixed with 30% coarse coal furnace ash. In hot summer, it can be placed under the outdoor shade or in a ventilated place under the shade of trees, with a shade of about 50%. Families living in buildings can hang pots under the scaffolding of the balcony, shaded by bamboo curtains, or hang pots where the inner side of southward doors and windows scatter enough light. Saffron needs less fertilizer at ordinary times, and it is better to apply some rotten liquid fertilizer every two weeks. When putting on the basin, an appropriate amount of livestock hoof horns and broken bones can be added as base fertilizer to make it grow well. For example, 0.1% solution of potassium dihydrogen phosphate and 20 times solution of rotten fish visceral water and bone water can promote the opening of autumn flowers. After putting on the basin, it is necessary to keep the basin soil moist and should not be too wet, especially when there is poor ventilation on the basin, the root system is easy to rot or cause fallen leaves to often spray water mist on the leaves, keeping the air humidity about 80%. Avoid the wind blowing the branches, so as not to break the drooping stems along the flowerpot. The weather is getting colder and colder in autumn, so the amount of water and fertilizer should be reduced gradually. The basin soil should be slightly dry in winter, except that some fertilizer liquid containing a little more phosphorus should be properly applied before the pregnant bud blossoms, generally speaking, there should be less fertilization or no fertilization. Temperature management the growth temperature of saffron is 18-30 ℃, the optimum temperature is about 25 ℃, and the cold resistance is poor. The overwintering temperature should be above 12 ℃. If it is found that the redness of lipstick leaves is mainly caused by too low room temperature or too strong light, the room temperature should be increased in time. If the room temperature is too low, it will cause the leaves to fall off and the branches to dry up. Lipstick flowers are not cold-resistant and need to be indoors in winter. Saffron is not strict with the air humidity, and the indoor air is not too dry to adapt. The suitable temperature for growth should be about 25 ℃, and the overwintering temperature should be above 12 ℃. If it is found that the lipstick leaves turn red, if the light is too strong or the room temperature is too low, the room temperature should be raised in time. If the room temperature is too low, the leaves will fall off and the branches will dry up. If the room temperature is suitable, the florescence of the saffron will be concentrated from December to February of the following year, when less nitrogen fertilizer should be applied, the indoor light intensity should be increased, and the lower room temperature should be controlled, which can promote the flowering of the carrot. After the winter flowering, the stump stems that have flowered should be cut off in time, which can save the consumption of nutrients and promote new shoots, so as to make them blossom. The pot culture substrate is loose and fertile slightly acidic rotten soil, which can be made of peat soil, sand and vermiculite, and an appropriate amount of calcium superphosphate is added as base fertilizer. 8 parts of rotten leaf soil mixed with 2 parts of coarse sand can also be used as substrate, and mature cow dung and horse dung can also be cultivated with 30% coarse coal furnace ash. Saffron needs less fertilizer in the process of growth, and an appropriate amount of livestock hoof horns and broken bones can be added as base fertilizer to make it grow well. Watering and fertilization of lipstick flowerpot soil should always be kept in a moist state, but avoid stagnant water in the pot, especially when the ventilation on the pot is poor, so as not to cause root rot, and the pot soil should be slightly dry in winter. In summer, fog water should be often sprayed on the leaf surface to increase the humidity of the leaf surface and the surrounding environment to facilitate its growth. Safflower needs less fertilizer at ordinary times, and it is better to apply some rotten liquid fertilizer every two weeks. Add appropriate amount of horns of livestock hooves and broken bones as base fertilizer when putting on the basin. During the vigorous growth period, saffron can be treated with mature organic fertilizer once every 15-20 days, and more phosphorus and potassium fertilizer can be applied after summer. For example, 0.1% solution of potassium dihydrogen phosphate and 20 times solution of rotten fish visceral water and bone water can promote the opening of autumn flowers. When the weather is getting cooler and colder in autumn, the amount of water and fertilizer should be reduced gradually. In addition to the proper application of liquid fertilizer with a little more phosphorus before the bud blossoms, there should be less fertilization or no fertilization in general. Under suitable conditions such as room temperature, the florescence of saffron will be concentrated from December to February of the following year, and less nitrogen fertilizer should be applied at this time. After the winter flowering period of pruning and breeding, the stump stems that have flowered should be cut off in time and the overlong drooping branches should be trimmed once, which can save the consumption of nutrients and promote the development of new branches, and more flowers will bloom in the coming year. The cultivation method of saffron should be preserved as a tropical flower, which has the habit of being warm and humid, avoiding strong direct sunlight, and grows luxuriantly under the eaves of a semi-shady and well-ventilated window. The suitable temperature for the growth of Carthamus tinctorius is between 20 ℃ and 30 ℃ throughout the year, and the cold tolerance is weak. If the temperature is lower than 15 ℃, the family should move to a warm and sheltered room in time, otherwise the leaves are easy to freeze and turn yellow. Saffron is more drought-resistant, avoid dampness and fear of waterlogging. In hot summer, fog water should be often sprayed on the leaf surface to increase the humidity of the leaf surface and the surrounding environment. Due to the long flowering period and flowering in summer and autumn, the supply of fertilizer and water should be adequate. It is best to bury mature organic fertilizer at the base of cultivation and apply flower fertilizer once a month during growth. Placed in the indoor decoration or hanging ornamental lipstick, usually the flowering period will end after 2 months, and the flowers will wither immediately. At this time, the overlong drooping branches can be trimmed once to promote the growth and germination of the new branches at the base, and more flowers will bloom in the coming year. At the same time, it can cooperate with post-anthesis pruning to reproduce, cut the cut branches into 8mur10cm, remove the lower leaves, obliquely insert them into plain sand, keep cool and moist, take root in about a month, and form a new plant. The length of cuttings cultivated in greenhouse can be shortened to 2-3 cm, a pair of leaves can be maintained at room temperature of 20-25 degrees Celsius, humidity above 50%, a large number of roots can be rooted and survived in about 10-15 days, and the branch length is more than 30 cm in about 10 months. The propagation of Carthamus tinctorius is commonly used by cutting, which can be carried out all year round under the condition of 20 ℃ to 30 ℃. Cutting propagation in spring is easy to live, cut off the 10~15cm long branches at the top of the branch as cuttings, cut them in clean river sand or vermiculite, keep the soil and air moist, avoid hot sun exposure, keep general room temperature, and root for about a month. Remove the bag after root hair, keep the basin soil slightly wet, and it can be transplanted in about 1-2 weeks. Several plants can be planted in each pot. Keep the soil moist when planting, not too much watering, otherwise it is easy to rot or cause fallen leaves. It can be directly cut in potted soil in summer. When the growth is exuberant, the heart can be properly removed to promote branching. The disease control of saffron has few diseases and insect pests, but when cultivated in summer, it is easy to suffer from anthracnose because of hot and humid weather. When the plant is sick, it often produces small spots on the leaves, and gradually expands to form yellow-brown round spots. When the disease is serious, more than half of the leaves wither and die, and sometimes disease spots are also produced on the stems. Keeping good ventilation, reducing air humidity and reducing the amount of nitrogen fertilizer in the cultivation field can prevent the occurrence of the disease. Pathogen Corynespora cassiicola (Berk. Et Curt) Wei called Coryosporium, the spores of which are numerous on the leaf surface and can also be produced on the back, but less. Conidiophores mostly solitary, fine, unbranched. At the beginning of the disease, 50% carbendazim 500 times solution or 65% Dysen zinc 500 times solution can also be used for prevention. In addition, in the process of cultivation, if there is a lack of calcium fertilizer. The terminal bud will be necrotic, so calcium superphosphate should be supplemented in the process of cultivation. In addition, when buying saffron, you should choose those with uniform branch growth, luxuriant branches and leaves, many flowers and dense flowers. Usually the lipstick is sold by hanging in the air. After buying, the drooping branches and leaves should be rolled up and wrapped in a newspaper or bag, otherwise it will cause damage to the drooping branches and flowers and affect the ornamental effect.

The key points of cultivation of Crocus sinensis

Carthamus tinctorius is an excellent hanging plant introduced in recent years, and its flowers and leaves have high ornamental value. Today, I'm going to tell you about the poison of saffron and the main points of its culture.

Is lipstick poisonous?

Before we say whether it is poisonous, let's first understand its morphological characteristics. Carthamus tinctorius is an evergreen vine with epiphytic nature and is often planted in a hanging basket. Leaves opposite, leaf blade ovate, elliptic or Obovate, leathery and slightly fleshy, leaf surface dark green, leaf back light green. Flowers axillary or apically clustered. Flowers born in pairs at the top of branches, with short pedicels, Corolla Chinese red to red-orange, calyx tube-shaped, black-purple tomentose, Corolla growing from the mouth of calyx, tube-shaped, bright red, like lipstick, so named.

The thick green leaves of saffron coupled with a bright red and strange Corolla are deeply loved by people. It is one of the best ornamental plants hanging in the family room. And it can absorb harmful gas formaldehyde, hanging orchid itself also has the function of absorbing toxic gases, generally raising a pot of safflower can well absorb the poisonous gases emitted by smoking and building materials in the air. Therefore, saffron is non-toxic, but an excellent ornamental plant that can effectively purify the air.

Key points of Culture of Crocus sativus

1. Basin soil

The pot soil is slightly acidic, and the pot culture soil made of peat soil, sand and vermiculite can be added with appropriate amount of calcium superphosphate. It can also be cultivated with 8 parts of rotten leaf soil mixed with 2 parts of coarse sand, and with mature cow dung and horse dung mixed with 30% coarse coal furnace ash.

2. Watering

Lipstick flowerpot soil should always be kept moist, but avoid stagnant water in the pot, especially when there is poor ventilation on the pot, so as not to cause root rot, and the pot soil should be slightly dry in winter. In summer, fog water should be often sprayed on the leaf surface to increase the humidity of the leaf surface and the surrounding environment to facilitate its growth.

3. Temperature

The growth temperature is 18-30 ℃, and the optimum temperature is about 25 ℃. The cold tolerance is poor. The overwintering temperature should be above 12 ℃. If it is found that the redness of lipstick leaves is mainly caused by too low room temperature or too strong light, the room temperature should be increased in time. If the room temperature is too low, it will cause the leaves to fall off and the branches to dry up.

4. Disease control

The diseases and insect pests of saffron are less, but when cultivated in summer, due to hot and humid weather and other reasons, saffron is easy to suffer from anthracnose. When the plant is sick, it often produces small spots on the leaves, and gradually expands to form yellow-brown round spots. When the disease is serious, more than half of the leaves wither and die, and sometimes disease spots are also produced on the stems. Keeping good ventilation, reducing air humidity and reducing the amount of nitrogen fertilizer in the cultivation field can prevent the occurrence of the disease.

5. Pruning

After the end of the blooming period, the flowers wither, and the overlong drooping branches can be pruned once to promote the growth and germination of the new branches at the base and produce more flowers in the coming year.

6. Points for attention

Families in the maintenance process, if the temperature is lower than 15 ℃, should be moved to a warm shelter indoor, otherwise the leaves are withered and yellow.
