What are the breeding methods of hibiscus

Hibiscus hibiscus

When it comes to the flowering season, the little hibiscus shows people the branches of flowers swaying in the wind, light and beautiful posture, brilliant flowers and colors, and the most important thing is that its flowering period is relatively long, so that more flower watchers can see its most beautiful side. In recent years, it has entered thousands of households and has become the best choice for indoor potted plants, so do flower friends know how to breed hibiscus in spring?

1. Sowing of the propagation mode of hibiscus

1. Sowing time

When young hibiscus is sown, generally speaking, spring is the time to sow seeds, but the author has also seen that some flower friends who sow seeds in June and September have also bloomed, so here we can boldly suggest that flower friends are not commercial breeding. second, the ability to control temperature is very good, so the sowing time can be appropriately relaxed.

two。 Sowing sequence

In addition, the germination time of the hibiscus, generally speaking, will sprout one after another two weeks after sowing, but it is also possible that because of the different sowing time, the germination time may be early or late at different temperatures, but wait patiently.

The following start to talk about specific sowing methods, in fact, very simple, and conventional sowing the same treatment, sowing soil, it is best to choose peat, or other professional sowing media, the germination rate will be relatively high, but if there is really no, you can also be relatively relaxed, with conventional sowing media.

After sowing, properly cover the soil, and then pour water through it. Some flower friends ask how thick the covered soil is, about 1 cm will be fine. Watering should be careful not to wash the covered soil away. If you sow the seed in early spring, the temperature is relatively low. You need film mulching. If the temperature is relatively high in summer or autumn, you can also cover the film, but it is best to make a few holes. The advantage of film mulching is moisturizing, high temperature, and help to sprout.

Second, the cutting of the propagation mode of Hibiscus hibiscus

1. Nursery bed cutting

Select 1-2-year-old robust unsprouted branches, if the hibiscus branches sprout and grow leaves, the new leaves should be removed, cut and grow 15-20cm segments, cuttings ready for a stick, according to the plant, row spacing in the seedling bed, and then insert hibiscus branches, compaction soil, into the depth of 10-20cm of the small section, that is, the depth of cuttings up to the depth of 2x3 is appropriate, immediately after cutting with enough water. There is no need to apply any base fertilizer when cutting.

two。 Tender wood cuttage

The optimum time for softwood cutting should be the vigorous growth period from June to July. The mother plant with strong growth and free of diseases and insect pests was selected, and the branches of one-year-old plants with vigorous growth, good development and free of diseases and insect pests were cut as cuttings. When different growth parts or different branches of the same branch were selected as cuttings, there were some differences in rooting rate and rooting quality. Generally speaking, the sprouting branches at the base of the mother plant are easier to survive and have better rooting quality than the upper branches, and the upper branches of the same branch take root better than the lower branches. Cuttings should be cut along with cutting to prevent water loss and wilting. When making cuttings, the branches should be cut into small segments of 10~15cm, each cuttings have 2 full buds, two leaflets, the lower incision is cut into a horseshoe shape, the cut is near the bud, the upper cut is flat, and the cut is about lcm from the lateral bud.

3. Potted cuttage

When indoor potted cuttings, choose 1-2 years to grow strong branches, grow about 10cm, remove the lower leaves, cut off half of the upper leaves, cuttings in a small bowl with coarse sand as the matrix, moisturize with plastic cover, maintain high humidity, under the condition of 18-25 ℃, it can take root in about 20 days.

Editor's note: if you are a novice flower friend, it is recommended to sow more seeds when breeding hibiscus, and insert more branches when cutting, so that you don't have to worry about the low survival rate. Of course, if you breed hibiscus in the above way, you will not be disappointed.

[FAQ] what are the breeding methods of hibiscus?

[expert answers]

1. Split-plant propagation of hibiscus

Before sprouting in early spring, the adult plants with exuberant growth were dug up and planted with 3 main branches as a clump according to the plant and row spacing of 50 × 60 cm.

2. Cutting propagation of hibiscus.

Method 1: generally adopt cuttage propagation in spring and blossom in summer and autumn of that year. The cutting method is as follows: after the local temperature has steadily passed 15 ℃, select 1-2-year-old strong unsprouted branches (if the hibiscus branches have sprouted and long leaves at the time of cutting, the new long leaves should be removed), cut off the length of 15 cm to 20 cm. When cutting, prepare a small stick, pre-insert a small hole according to the row spacing, and then insert the hibiscus branches into the soil at a depth of 10 cm to 15 cm, that is, the depth of the cuttings is 2 cm, compacting the soil, and filling with water immediately after cutting. Note that there is no need to apply any base fertilizer when cutting.

Method 2: the cutting density varies according to seedling transplanting or direct planting. Seedling transplanting: in order to facilitate the operation, the furrow width is 130 cm, the height is 25 cm, and the plant spacing is 15 cm × 30 cm. Direct planting: it can be planted according to the border groove 60 cm, height 25 cm, plant spacing 50 cm, single row planting, or 90 cm, 25 cm high, 60 cm plant spacing, single border and double row "product" shape. In cultivation, we can make use of the flowering characteristics of the cutting seedlings in the same year, cut according to the seedling transplanting density, and carry out the seedlings according to a certain density before sprouting in spring every year after the second year, so as to ensure that the hibiscus hibiscus has sufficient nutritional area in the same year and capture the high yield of flowers.

Method 3: cutting requires that the furrow depth is 15 cm, the furrow distance is 20-30 cm, the plant spacing is 8-10 cm, the upper end of the cuttings is 3-5 cm exposed to the soil or the depth of the cuttings is 2 cm, after cutting, the soil is compacted and watered in time. The cuttings generally take root and sprout in about one month, using heat preservation facilities such as plastic greenhouses, and cuttings can also be raised after defoliation in autumn. The cuttings are soaked in 100-200mg / L NAA solution for 18-24 hours, then cut into the sand bed, watered in time, covered with agricultural film, maintained temperature 18-25 ℃, relative humidity more than 85%, rooting and moved to the nursery for cultivation.

3. Striping propagation of hibiscus

Striping propagation is a method of propagation that makes the branches connected to the mother plant form adventitious roots, and then cut off the mother plant to become a new individual. During striping, circular peeling can be carried out in order to interrupt the downward transport of organic matter such as sugar, auxin and other substances from the upper end of leaves and branches, so that these substances accumulate in the upper part of the treatment and can be used for rooting. Application of 1BA auxins on the girdling site can promote rooting. For families or individuals, the number of hibiscus in demand is small. At this time, we can use high branch crimping, hibiscus branch rate is basically full, but also grow fast.

4. Sowing and propagation of hibiscus

When small hibiscus is sown in spring, it can be treated the same as conventional sowing. When sowing soil, it is best to choose peat or other professional sowing medium. The germination rate will be relatively high, but if there is no such medium, you can also relax a bit and use conventional sowing medium to OK.

After sowing, properly cover the soil, and then pour water through it. Some flower friends ask how thick the covered soil is, about 1 cm will be fine. Watering should be careful not to wash the covered soil away. If you sow the seed in early spring, the temperature is relatively low. You need film mulching. If the temperature is relatively high in summer or autumn, you can also cover the film, but it is best to make a few holes. The advantage of film mulching is moisturizing, high temperature, and help to sprout.

[editor's comments] the above are the four propagation methods of hibiscus: sowing, striping, cutting and splitting, but in fact, hibiscus is mainly used in cutting propagation and split propagation. I hope this article will be helpful to you and more related materials.

Culture methods of Hibiscus hibiscus L., 7 culture items

Hibiscus culture method 1. Adapt to the environment

Small hibiscus likes light. According to observation, many flower friends' small hibiscus are placed on the south balcony, with plenty of light and growing well.

2. Selection of basin soil preparation.

The cultivation medium should choose the soil with good permeability and drainage, the general nutritious soil sold in the market, or the nutritious soil made of mountain mud (rotten leaf soil) plus a small amount of river sand and organic fertilizer, and avoid clayey soil (some people have seen Hua you use ordinary garden soil). To sum up, the soil with conditions can choose nutritious soil with good air permeability and good water permeability, and those without conditions can also be tried with ordinary garden soil.

3. Flowerpot selection

Hibiscus hibiscus grows very fast, so flower friends need to buy slightly larger flowerpots, such as ceramic pots with good air permeability. In late autumn, hibiscus needs to be pruned in time, pruning long branches, diseased branches, withered branches and residual branches, so as not to consume too much nutrients and affect the growth and development of the following year.

4. There is plenty of sunshine

Hibiscus hibiscus is a kind of flowers that like sunshine and warm heat, so the demand for sunlight is quite high. It is necessary to move the hibiscus constantly in the process of maintenance to prevent the growth deviation of hibiscus caused by one direction for a long time. The summer weather is too hot, need to put it in the balcony with sufficient scattered light, and maintain ventilation, you can safely through the hot summer.

5. Water quantity control

Summer hibiscus in the maintenance process must pay attention to watering, because water makes the hibiscus summer is the key, when the weather is too hot, when the temperature rises, it needs to be watered once a day. If you forget to water it, there will be a lot of withered and yellow leaves.

When the direct sunlight temperature is too high, it must be watered once a day, and the water must be thoroughly watered. If the hibiscus is short of water, it will easily die. Stop watering it during winter dormancy.

6. Fertilizing to supplement adequate nutrition

Small hibiscus likes big water and big fertilizer, according to observation, so flower friends should ensure adequate water and fertilizer when raising small hibiscus. Flower friends ask what fertilizer to apply, all kinds of slow-release fertilizer, flower-watching fertilizer, and so on. Winter enters the dormant period, stop fertilizing.

7. Pruning in time

When small hibiscus pruning, flower friends dare not start pruning small hibiscus, looking at the lush hibiscus, can not go down, in fact, small hibiscus is very resistant to pruning, generally can be light or heavy pruning, light pruning can cut off branches of 1x3, heavy pruning off the ground 10cm above all branches, pruning can promote plant renewal and rejuvenation.
