How to raise red-edged plantain in potted plants?

Plant name: Tricolor iron; scientific name: Dracaena marginata; alias: red edge Zhu Jiao.

Red banana originated in China and India. Likes warm, humid and sunny environments. Not cold, afraid of waterlogging, avoid the sun exposure. The optimum temperature for growth of Viburnum bungeanum is 20~25℃, 25~30℃ in summer during the day and 7~10℃ at night in winter. Not lower than 4℃, individual varieties can withstand 0℃ low temperature. It is obvious that the adaptability of Zhujiao is stronger. Zhu banana is sensitive to water. The soil must be kept moist during the growing season. Water shortage easily causes defoliation, but too much water or ponding in the basin also causes defoliation or leaf tip yellowing. Water is often sprayed during the growth period of stems and leaves, and the air humidity of 50%~60% is more suitable. Zhu banana has strong adaptability to light. Bright light was the most beneficial to the growth of Viburnum bungeanum, but short period of strong light or long period of semi-shade had little effect on the growth of Viburnum bungeanum. Appropriate shade at noon in summer, reducing the intensity of light, is very beneficial to the growth of red banana leaves. Soil to fertile, loose and good drainage of sandy loam is appropriate, not resistant to salt and acid soil. Potting commonly used decaying soil or peat soil and culture soil, coarse sand mixed soil.

Propagation methods: commonly used cuttage, layering and sowing propagation. Cuttage propagation: the branching ability of Zhu Jiao is poor, so it is necessary to cultivate the mother plant, cut the top branch from June to October, 8~10 cm long, with 5~6 leaves, cut short, insert it into the sand bed, keep it moist, and the suitable temperature is 24~27℃, not lower than 20℃. After sowing 30~40 days, take root and sprout, and pot when the new branches grow to 4~5 cm. When cuttings were treated with 0.2% IBA for 2 seconds, rooting rate was increased and rooting days were shortened. Layering propagation: high-altitude layering is commonly used in May to June. Select the strong main stem, 20 cm from the top, peel it in a ring, 1 cm wide, cover the wet moss, wrap it with plastic film, keep it at room temperature above 20℃, root after about 40 days, and cut off the potted plant after 60 days. Sowing and propagation: Zhu Jiao seeds mature in September, the seeds are larger, often used shallow pot sowing, germination temperature is 24~27℃, germination after 2 weeks, seedling height 4~5 cm transplant 4 cm pot.

Cultivation management: potted red banana commonly used 15~25 cm pots, seedlings 20 cm high when planting. Fertilize once every half month in growth period or use "Huiyou"20-8-20 four seasons with high nitric acid potassium fertilizer. The longer the main stem is, the higher the base leaves gradually wither and fall off. It can be shortened to promote the germination of more branches, and the crown is more beautiful. Leaves often spray water to keep stems and leaves fresh and lush. And pay attention to indoor ventilation to reduce pest hazards. Change pots once every 2 - 3 years.

Pest control: mainly anthracnose and leaf spot damage, available 10% antibacterial agent 401 acetic acid solution 1000 times liquid spray. Sometimes scale insects harm leaves, with 40% omethoate EC 1000 times spray kill.

The sun god potted plant that can remove dust and absorb formaldehyde, how to raise dense leaf Zhu banana

Today's flower bonsai network Xiaobian wants to share with you is about the sun god potted plants that can remove dust and absorb formaldehyde, and how to raise dense leaves. Let's take a look.

The Helios potted plant did not need to be maintained. Its name was originally called Dense-leaf Red Banana. Later, I don't know why it had other names for Helios and Apollo. Raising a few pots of Helios at home could achieve a good dust removal effect and purify more air. Moreover, it usually did not need much care. It could grow very well by itself and was very suitable for rough cultivation.

Does it look like the sun from the top?

How to improve God's ability to purify the air?

It can not only produce oxygen, reduce indoor carbon dioxide, but also achieve a good dust removal effect, if often clean leaves, its cleaning effect is better, so you can occasionally spray it with water, or wipe the leaves with a soft wet cloth.

It can also purify some volatile organic pollutants, such as trichloroethylene, benzene and formaldehyde produced by decorative materials, all of which have a certain purification effect.

II. Several key points of conservation:

1. Light

Helios can tolerate shade. If placed in a bright space, the plant will grow stronger as a whole, but avoid direct sunlight, otherwise it will cause burning and brown spots on the main surface.

If the sun god's dark green leaves fade, it is very likely that the ambient light is too weak.

(Helios blossom)

2. Temperature and humidity

Maintenance attention to maintain a certain humidity, air is too dry when the appropriate water spray humidification, to avoid dry air caused by dry leaves or withered.

The temperature is kept above 10 degrees, the lowest temperature is not lower than 5 degrees, and the growth is most vigorous between 18 and 32 degrees.

3. Watering

Sun God likes pot soil dry and thoroughly watered, soil surface to 5 cm below the soil are dry, good watering, excessive watering will make leaves yellow and fall off, should avoid potted soil too wet or ponding.

Poor light environment or low temperature will reduce the watering frequency, it is also drought-tolerant plants, in winter to reduce the amount of watering, soil dry and then wet is the best watering method.

4. Fertilization

It is best to use the nutrient solution of foliage plants once a month, diluted with water in a small pot each time, and the concentration cannot be high.

It is suggested to fertilize in spring, adjust to fertilize once every month if fertilizer is needed in other periods, and not recommend fertilization in winter.

III. Precautions for conservation:

1. Moderate pruning can be done from time to time for the appearance of blackened areas. In order to control its growth, it is recommended to prune in spring or early summer. You can truncate its plants at any height. It will develop a new leaf group from the cut place, but it will grow slowly.

Too wet or too dry soil can cause leaf loss.

3, excessive watering will make the leaves yellow and fall off, should avoid potted soil too wet.

4, in the air is dry, the plant will induce red spiders, found when it should be treated with pesticides, usually pay attention to increase the environmental humidity.

(Lingnan Collection of Medicinal herbs) [reference source] the propagation methods of Zhu banana are commonly used in cutting, striping and sowing. Cutting propagation: the branching ability of Zhu banana is poor, and the mother plant must be cultivated. The top branches should be cut from June to October, with 8 cm in length and 6 leaves, cut short, inserted into the sand bed and kept moist. The optimum temperature is 24-27 ℃, not less than 20 ℃. It took root and sprouted 30-40 days after sowing, and was potted when the new branch grew to 4-5 cm. The cuttings were treated with 0.2% indole butyric acid for 2 seconds, which could increase the rooting rate and shorten the rooting days. Striping propagation: high-altitude crimping is commonly used in May-June. Select the strong main stem, 20 cm from the top, peel it in a ring, 1 cm wide, cover the moist moss and wrap it with plastic film, keep it at room temperature for more than 20 ℃, root after about 40 days, and cut off the pot plant after 60 days. Sowing and propagation: the seeds of Zhu banana mature in September, and the seeds are larger. They are often sown in shallow pots. The optimum temperature for germination is 24-27 ℃. After 2 weeks of sowing, they germinate, and the seedlings are 4-5 cm high and transplant in 4 cm pots. Cuttings are commonly used in propagation. From May to June, the part with growing point at the top of the branch was cut as cuttings, the lower leaves were removed, and inserted into the medium mixed with plain sand and peat soil. Shade-thinning, heat preservation and moisturizing tube protection was used to take root in about 30 days at 25 ℃ to 30 ℃. The mother plant of cutting cuttings can sprout several tillers from the rhizosphere, and these tillers can still be used as cuttings in the coming year. In professional units, some mother plants specially used for ear sowing are often cultivated for reproduction. The older the plant is, the more strips will be picked. When the lower leaves of the old plant cultivated for several years fall off, the stem can be cut off from the 5~lOcm on the basin, and the old plant can be replanted with soil change. let it sprout new branches, or take its underground stem for burying. The top part of the cut can be cut into branches. When cutting branches, remove part of the leaves or cut them short to prevent excessive transpiration of water from affecting survival, and then cut them straight. After insertion, it needs to be moisturized with plastic film, and the bottom temperature is 3035 ℃. It can take root in 2-3 weeks. When the stem is inserted or buried, the stem or underground stem should be cut into a short section of 2~3cm, and then it can be inserted directly or horizontally, no matter which kind of insertion method should be shallow, so that the cuttings can not be seen, but when the stems are inserted straight, they should be slightly deeper to prevent the cuttings from showing too much and easily wither. When inserting directly, be careful not to turn the insert upside down. The cutting period is usually from June to July, and the cutting is carried out in a shallow basin with turbulent sand. You can also take the method of burying dry cuttings, cut 5 cm to 10 cm of mature branches, cut off the leaves, and bury them horizontally in the pure river sand. You can also cut about 3 cm thick branches, cut a wound every 5 cm, up to a dry diameter of 1 stroke 2, horizontally buried in the sand, the upper part slightly exposed sand, placed in a shade-thinning, ventilated, moist environment, about 20 days later, it can take root from the incision, sprout at the node, and then cut off and plant. Family flower cultivation can be planted in a jar from May to June and can take root in about 3 weeks. The biological characteristics of cultivation techniques of Zhu Jiao prefer high temperature and high humidity, with a low temperature threshold of 10 ℃ in winter and semi-overcast in summer. Avoid alkaline soil. The cultivation techniques can be propagated by cutting, dividing roots and sowing seeds. Stems and leaves are easy to produce adventitious buds and can be picked for reproduction; mature branches are used in early spring, leaves are removed, 5-10cm segments are cut and placed flat in the bottom temperature hotbed, which keeps 25-30 ℃ and moist air in the hotbed, which can take root in about 1 month; after cutting off the terminal bud, the base of the branches will germinate a lot of branches, which can be used as propagation material after 1 year; the older plants in the tropics can collect seeds, so it is easy to sow and germinate in spring. It is easy to cultivate and manage. Pot transplant with loose, drained and ventilated 5-40mm imported peat, mix the peat with water, (standard of adding water: mix well with water, hold a handful of peat, water oozes from fingers) to be planted in cup. [6] potted Zhu banana is often planted in a pot of 15cm to 25cm and planted when the seedling is 20cm high. During the growing period, Zhu Jiao was fertilized once a month or "Huiyou" 20Mel 8Mel 20 was used with high potassium nitrate fertilizer for four seasons. As the main stem grows taller and taller, the basal leaves gradually wither and fall off, which can be truncated to promote the germination of more lateral branches, and the crown is more beautiful. Leaves are often sprayed with water to keep the stems and leaves fresh and luxuriant. And pay attention to indoor ventilation to reduce the harm of diseases and pests. The basin is changed every 2-3 years. Post-natal treatment of Zhu banana plant shape is beautiful, the color is gorgeous and elegant, pot planting is suitable for interior decoration. Potted young plants are dotted with guest rooms and windowsills. Zhu Jiao can endure dark conditions for 15 days. During storage and transportation, the temperature should be kept at 16: 18 ℃, and the relative humidity should be 80% 90%. Main points of cultivation 1. The suitable temperature for the growth of Zhu Jiao is 20: 25 ℃, 25: 30 ℃ during daytime in summer and 7: 10 ℃ at night in winter. It can not be lower than 4 ℃, and some varieties can withstand 0 ℃ low temperature. It can be seen that Zhu Jiao has strong adaptability. two。 Zhu Jiao is sensitive to water. The basin soil must be kept moist during the growing period. Lack of water is easy to cause fallen leaves, but too much water or stagnant water in the basin also causes fallen leaves or leaf tip yellowing. Stems and leaves are often sprayed with water during the growing period, and the air humidity of 50% to 60% is more suitable. 3. Zhu Jiao has a strong ability to adapt to light. Bright light is the most beneficial to the growth of Zhu Jiao, but the strong light for a short time or semi-shade for a long time has little effect on the growth of Zhu Jiao. Proper shading at noon in summer and weakening the light intensity are very beneficial to the growth of plantain leaves. 4. The soil should be rich, loose and well-drained sandy loam, which is not resistant to saline-alkali and acid soil. Potted plants are often mixed with rotten leaf soil or peat soil and culture soil and coarse sand. The propagation of cultivation and conservation of Zhu banana is mainly by cutting, which can be carried out from June to October. The old plant whose lower leaves fall off is cut into segments of about 5 cm. After the incision is slightly dry, it is inserted into sand or hydrocarbon stone, or it can be buried horizontally in the matrix, slightly covering the soil, keeping about 25 ℃ and a certain humidity, and rooting and sending out new plants in 3 weeks. It can also be propagated by high pressure and sowing. The cultivation of plantain is relatively easy, and the potted soil is made of 2 parts of rotten leaf soil and 1 part of sand or sawdust to make it slightly acidic. Zhu Jiao likes light and grows vigorously under sufficient and wet conditions, but the summer light is too strong, which is not conducive to the growth of Zhu banana. The leaves are easy to aging and dark, so we should pay attention to shading. In the growing season, in addition to watering to keep the soil moist, fertilizer should be applied once every semimonthly. When the weather is dry, water should be sprayed to the leaves to humidify. In winter, it should be placed in a place with sufficient indoor light to reduce watering, dry rather than wet. If the plant is prone to shell insects in a poorly ventilated environment, attention should be paid to prevention and control. The disease control of Zhu banana mainly includes anthracnose and leaf spot, which can be sprayed with 1000 times of acetic acid solution. Sometimes the leaves are damaged by scale insects, which are sprayed with 1000 times of omethoate EC. Zhu Jiao pictures
