How to plant firecrackers by cutting (teach you how to plant firecrackers simply)

In addition to firecrackers, the spring breeze brought warmth to Tusu. In China, the custom of setting off firecrackers in the Spring Festival has a long history, and the Spring Festival without firecrackers is not lively enough and complete enough. On this happy and festive day, there is a kind of "flowers shaped like firecrackers" that is also in full bloom, adding a touch of joy to the Spring Festival, that is, fireworks. Today, Xiaoqi will share with you "How to propagate fireworks by cutting and the maintenance skills after cutting propagation".

Fireworks, also called firecrackers, are vines of Lagerstroemia. The leaves are green and oval, and the flowers are shaped like strings of firecrackers. Fireworks usually bloom from 65438+February to March of the following year, and orange flowers are dotted among the green leaves. From a distance, they are like firecrackers on New Year's Eve, symbolizing prosperity and adding a lot of festive atmosphere to the Spring Festival. That's great.

How did such beautiful fireworks breed into more than one plant? In addition to the well-known sowing methods, the propagation of fireworks can also be carried out by cutting. This paper focuses on the topic of "cutting propagation methods and maintenance skills of fireworks", hoping to help everyone.

Definition of cutting propagation of fireworks

Cutting propagation of fireworks is a common asexual propagation method, which uses the regeneration ability of plant branches to select branches with strong growth and regeneration ability, plants them in suitable soil matrix after treatment, and promotes them to take root and sprout after later maintenance and management, and develops into fireworks plants with independent life.

Reasons and advantages of cutting propagation of fireworks

Reasons for cutting propagation: As we all know, flowering plants can only bear fruit after pollination, but fireworks are called "flowers only fade" plants. Because fireworks are pollinated by hummingbirds, although they are also rich in nectar, the slender corolla tube restricts the pollination of animals other than hummingbirds, and there are no hummingbirds in China and even the whole Eurasia, so fireworks can't be pollinated naturally, nor can they bear fruit, of course, it is even more impossible to have seeds. However, artificial pollination is relatively complicated, and the stout branches of fireworks have strong regeneration ability, so the most commonly used propagation method of fireworks is cutting. This is why cutting is chosen to breed fireworks.

Advantages of cutting propagation: Cutting propagation of fireworks has three advantages. Advantages 1: relatively simple operation and high survival rate. Advantages 2: quick seedling cutting, early flowering, reasonable maintenance and general flowering in the same year. Advantage 3: Cutting propagation can continue the excellent characters of the mother plant and avoid variety variation.

The best time for cutting propagation of fireworks

Growth habit: Fireworks originated in Brazil in South America and are widely cultivated as garden ornamental plants. It likes sunshine, warm and humid environment, and the suitable growth temperature is 15-25 degrees. It is neither high nor cold-resistant, and the temperature should not be higher than 30 degrees in summer and lower than 8 degrees in winter, otherwise the plants will grow poorly or stagnate. The flowering period of fireworks can be as long as 6 months. Fireworks grow quickly. In South China, they can keep evergreen branches and leaves and can spend the winter in the open air. They like loose, breathable, well-drained and fertile acidic sandy loam.

Best time: According to the growth habits of fireworks, the temperature in winter is low and the summer is hot, which is not suitable for cutting propagation. The climate in spring and autumn is pleasant, which is conducive to root growth. Seven people think that April-May in spring is the best time for cutting propagation of fireworks, because the climate is more comfortable and humid, which is more conducive to the development of plant roots and has a higher survival rate.

Note: It is rainy in some areas from April to May in spring. If you choose rainy weather for cutting, it is easy to have incision infection, which leads to the failure of cutting propagation. Therefore, in order to avoid incision infection, we should choose a sunny time for cutting propagation.

Operation method for cutting propagation of fireworks

Although the operation of fireworks cutting propagation is relatively simple, some auxiliary tools are needed to successfully complete the cutting operation. Therefore, in order to ensure the smooth propagation of cuttings, sharp knives, alcohol, carbendazim, rooting powder and so on can be prepared in advance.

1, preparation of soil

Fireworks are not particularly strict with soil, but loose, breathable, well-drained and fertile acid sandy soil is more conducive to plant growth, thus improving the survival rate of cuttings. If the soil is too sticky, it is not conducive to the growth and development of roots. We can choose humus soil, garden soil and sandy soil, mix them evenly, in which the proportion of garden soil is less, and then add a small amount of bone meal as base fertilizer.

Step 2 choose a flowerpot

Fireworks are not very demanding on flowerpots, as long as the flowerpots have good ventilation and drainage performance. The size of the flowerpot can be determined according to the number of cultured plants, or you can choose a larger flowerpot, so you don't need to change the flowerpot in the later stage of planting. Xiaoqi suggested to choose a large deep crock or clay pot with many fine holes at the bottom.

3. Select the mother plant

For the cutting propagation of fireworks, the growth state of the mother plant determines the regeneration ability of branches. If the plant grows poorly or is infected with diseases and insect pests, the rooting rate of branches will decrease. Therefore, it is necessary to select plants with vigorous growth and no pests and diseases for cutting, so as to improve the survival rate of cutting propagation.

3. Cut the cuttings

In cutting propagation, branches with good growth and no diseases and insect pests should be selected, and the cutting length is about 10- 15 cm, and each cutting needs 3-4 nodes and 2 buds. Then use an alcohol-sterilized knife to cut it 0.5 cm below the selected branch node, and the incision should be smooth.

4, processing chips

The cut cuttings can't be cut at once because there is a cut in the cuttings. If it is not disinfected, it is easy to be infected with bacteria, and the cuttings will rot, reducing the survival rate of cuttings. Therefore, the cuttings should be disinfected with carbendazim in time after cutting, dried in a cool and ventilated place, and then coated with rooting powder.

5, cutting.

Insert the cuttings into the prepared pot soil, and the depth of the cuttings should not be too deep, which is about two-thirds of the depth of the cuttings. Then press the base of the cuttings with your fingers, so that the base of the cuttings is closely combined with the soil without leaving gaps. Finally, spray enough water with a watering can and put it in a cool and ventilated place for maintenance.

Note: Before cutting, fully expose the prepared soil for 1-2 days, so as to prevent eggs or bacteria contained in the soil from infecting the cutting incision, resulting in cutting failure.

Maintenance and management of fireworks after cutting propagation

1, moisture

Fireworks like warm and humid environment, but frequent watering is not conducive to the survival of newly cut fireworks cuttings. If the water is too frequent or too much, the soil will be wet for a long time, and then the cuttings will rot or the newly grown roots will rot easily, which will lead to the failure of cuttings propagation. Therefore, it is only necessary to keep the soil slightly moist but not too dry. Spraying water with a watering can every 1-2 days can not only moisten the soil, but also increase the air humidity.

2. Lighting equipment

Although fireworks are flowers and plants that like light, for cuttings whose roots have not yet sprouted, too strong light will burn the bud points on the cuttings, which is not conducive to rooting and sprouting. Therefore, it can be maintained in a cool and ventilated place, occasionally giving astigmatism, and then maintained under normal light after it takes root and grows steadily.

Transplanting and planting after cuttage survival

After cutting for about 4 weeks, if the stems and leaves are still green and there is no wilting, it means that the incision has healed well and independent roots have grown. If fireworks are not transplanted after survival, they will grow poorly because of small growth space and insufficient nutrition. So when the seedlings of fireworks grow to about 15 cm, they can be transplanted and planted.

1. Potted soil

Based on the characteristics of fireworks as climbing plants, we can choose breathable flowerpots with larger diameter and deeper depth. When preparing pot soil, it can be made according to the soil when cutting, and the principle of "loose and breathable, well drained and acidic" is followed. Moreover, the soil should be disinfected by exposure to sunlight 1-2 days or disinfection with carbendazim solution.

2. Maintenance points: For the newly transplanted fireworks seedlings, normal maintenance management cannot be carried out immediately. First, keep the seedlings in a ventilated and soft light environment, and then keep the soil slightly wet. Just pour a proper amount of water every three days, or spray water with a watering can. Seedlings with unstable growth cannot be fertilized. After the seedlings grow stably, they should be maintained normally according to the growth habits of fireworks.

Conclusion: Cutting is a more suitable method for fireworks propagation. First, prepare suitable pot soil, then cut cuttings from strong plants without pests and diseases, and then cut them after treatment. In order to improve the survival rate of cutting, we should pay more attention to the management of light and water, transplant and plant the seedlings when they grow up, and then carry out normal maintenance after the growth is stable.
