Three common propagation methods of Zhu banana

Zhu Jiao, also known as Red Iron Tree (details), is mainly distributed in the tropics of southern China and is often used for courtyard cultivation. Because Zhu Jiao is a semi-shade plant, exposure to the sun and complete shade will make Zhu Jiao lose its ornamental value. Artificial propagation of Zhu Jiao can choose the methods of cutting, pressing and sowing. The editor will briefly introduce to you these three breeding methods of Zhu Jiao.

Zhu Jiao

1. Cutting

The common propagation method is cuttage from June to October. The branching ability of Zhu banana is poor, so it is generally specialized in cultivating tall and robust mother plants for cutting propagation. When breeding in the family, the mature branches at the top are cut off from the plant, the cuttings that grow 10mur15cm are cut, the leaves on the branches are cut off or the leaves are retained, and then the sand is used as the substrate and inserted into the sand bed or basin soil. the depth is about 6 cm. The cuttings were placed under the shade after cutting. If the temperature is 25 ℃ and 30 ℃ and the air humidity is high, it can take root and sprout in 40 days. When the length of the new branch is about 5 cm, it can be transplanted into the pot for single plant culture.

2. High-altitude pressing strip

When the family does not breed much and wants to cultivate large plants as soon as possible, high-altitude striping can be used to breed. It usually takes place from May to June. Choose the main stem of the strong plant, 20-25 cm from the top. Ring peeling, peeling width is 1 Mel 1. 5 cm, wrapped with wet peat soil or moss or vermiculite shell, wrapped into mud balls, wrapped with plastic film, fastened at both ends to avoid leakage of the matrix. Generally, it takes about 30 days to take root, and after 60 days, it can be cut off from the mother and planted in a pot.

3. Sowing seeds

The fruits were harvested after ripening in late summer and early autumn. Take the seeds from the berries, wash them clean, dry them, and sow them in a sand bed or basin. After sowing, the seeds can be germinated and unearthed after being kept at room temperature for more than 24 ℃. When the seedlings grow to about 6 cm high, move into the flowerpot, 1 plant in each pot, and continue to culture separately.

How does Zhu Jiao cuttage propagate?

Zhu Jiao plant type is more beautiful, the leaves are very eye-catching, if you have such a pot at home, it is still very good to watch, but do you know how to cultivate Zhu banana? I don't know. If there is a pot and you want to divide it into multiple pots, you need to consider the problem of reproduction. Jiuzheng will come to share with you how Zhu Jiao cuttings propagate. Let's take a look.

Culture methods of Zhu Jiao:

1. Planting

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.

2. Fertilization

Thin fertilizer and water or compound flower fertilizer are applied every half a month in the peak growing season.

3. Watering

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. The stems and leaves are often sprayed with water during the growing period, and the air humidity of 50% to 60% is more suitable, and the growing season should be well watered. In the dry season and hot summer weather, in addition to watering every day, water should be sprayed on the leaf surface 1-2 times, so that the leaves can appear moist and beautiful.

4. Temperature, light

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. Zhu Jiao is more shade-tolerant and can be cultivated indoors in half-light all the year round, and can also be maintained in outdoor shade in spring and autumn. In winter, move the flowerpot to a place with sufficient indoor light, reduce watering and stop fertilization, and the room temperature is not less than 10 ℃ to survive the winter safely.

5. Cultivation and maintenance

If the family indoor furnishings, the plant shape should not be too large, should be controlled. The fruit of Zhu Jiao ripens in late summer and early autumn. The seeds are large and should be harvested after the berries are ripe, washed and dried. Put the old pot soil into a wooden box or flowerpot for on demand, keep it at room temperature above 24 ℃, and sprout and unearth in about 15 days. When the seedlings grow to about 5 cm, move into the small flowerpot, 1 plant per pot, continue to cultivate the pot soil should always keep moist, rather wet than dry. Spray water to the leaves every day if the air is dry. Liquid fertilizer should be applied several times in spring and autumn, do not topdressing in summer and pay attention to heat prevention and cooling, if indoor muggy should be moved to outdoor shade. Move into the indoor winter in early October (there should be indoor heating equipment), see more sunshine, and can go out for maintenance in the first ten days of May of the following year. The perennial old plants will grow taller and taller, the old leaves fall off one by one, and the stems are bald, which hinders the ornamental, so it should be cut short in combination with cuttings to promote its multiple lateral branches. After being cut short, the management of fertilizer and water should be strengthened to promote the germination of dormant buds as soon as possible.

6. Disease control

It is mainly harmful to anthracnose and leaf spot, which can be sprayed with 1000 times of acetic acid solution of 10% antibacterial agent. Sometimes the leaves are damaged by scale insects, which are sprayed with 1000 times of omethoate EC.

How does Zhu Jiao propagate by cuttage?

When Zhu Jiao is cutting, he can choose soil cutting or water cutting, which is relatively simple.

When cutting the soil, cut the branches horizontally into the soil, cover them with plastic film, and pay attention to shading. In the water insertion, the speed of rooting is relatively fast, and the root system can be seen in a week.

The time of cuttage propagation of Zhu Jiao

Cutting propagation is a common propagation method of Zhu banana, and there are still many time choices for cutting propagation, as long as the conditions are suitable, cutting can be carried out all the year round. If the cuttings are carried out in spring and autumn, the survival rate will be very high, and the rooting rate will be relatively slow in winter.

Selection of cuttings of Zhu Jiao

Zhu Jiao should pay attention to the selection of cuttings when cutting. When the eye is pruning, the pruned branches can be used for cutting. Just choose the one with stronger growth.

In fact, the cuttage of Zhu banana can be divided into two cases. The first is to use the terminal bud for cutting. when selecting cuttings, it is necessary to choose branches with terminal buds, so that the speed of rooting will be faster. When cutting cuttings, there is no fixed requirement for length, in general, the length is between 15cm--30cm.

In addition, Zhu Jiao can also carry out hardwood cuttings, mainly by removing the terminal buds from the branches, and then cutting branches with a length of about 10--15cm as cuttings.

Propagation methods of Zhu Jiao (red iron tree) Zhu banana (red iron tree) is commonly used in cutting, striping and sowing and propagation. one。 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. two。 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. three。 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. Zhu Jiao plants are beautiful in shape, gorgeous and elegant in color, and potted plants are suitable for interior decoration. Potted young plants, decorated with guest rooms and windowsill, are elegant and chic. There are lots of venues, public places, rooms and entrances and exits, dignified and tidy, fresh and pleasing to the eye. Several pots are furnished with shop windows and teahouses, making them more elegant and luxurious. Zhu Jiao can endure the dark state for 15 days. The temperature should be kept at 16: 18 ℃ and the relative humidity should be kept at 80% 90% during storage and transportation. Pest control: mainly anthracnose and leaf spot damage, can be sprayed with 1000 times of acetic acid solution of 10% antibacterial agent. Sometimes the leaves are damaged by scale insects, which are sprayed with 1000 times of omethoate EC.
