Hibiscus breeding methods, what are the breeding methods of hibiscus?

First, the reproduction method of hibiscus:

Hibiscus propagation methods include sowing, striping, cuttings, cuttings, cuttings: after the buds are 1 2 years long, dig and transplant with some roots, it is easier to survive cuttings, before germination in spring, cut the branches 20 25 cm long, insert them in the sand bed, and take root in about 30 days. Wood seeding:

Hibiscus seed after dry storage to the next spring sowing, sowing is generally carried out in spring April, hibiscus top soil capacity is very strong, low temperature dry storage after the seed is soaked and germinated can be sown, generally strip sowing or sowing. After sowing, you can use artificial soil or mechanical soil covering, and it is better to cover the soil within 5cm.

Second, the suitable environment for hibiscus:

Hibiscus is very adaptable to the environment, more resistant to dryness and barrenness, less strict soil requirements, and prefers light and warm and humid climates. Slightly shade-tolerant, warm, humid climate, pruning-resistant, heat-resistant and cold-resistant, but cultivation in the northern region needs to protect the winter, good water and humidity and drought tolerance, the soil requirements are not strict, and it can also grow in heavy clay soil.

Third, the arrangement of the land for hibiscus sowing:

Prepare the seedbed, that is, clean up the weeds and garbage, and then carry out deep turning, rake flat after mixing fertilizer, and try to break the soil clods, according to the furrow with a width of 130 cm, a height of 25 cm for furrowing, 6 kg of manure per square meter, a kilogram of fire soil, 75 grams of calcium, magnesium and phosphorus as base fertilizer. The clods are broken for better germination and growth of the seeds, and the furrowing is for better management and drainage irrigation at a later stage.

Fourth, the maintenance of hibiscus:

After germination, hibiscus seeds germinate about 10 days after sowing, and come out on the 20th, sowing and covering fine soil after watering again, and then pay attention to maintaining temperature and humidity to obtain a good seedling rate, after the emergence of seedlings should pay attention to provide sufficient light, but not suitable for too strong, the sun is too strong to pay attention to shading.

It is easy to root, and it is mostly propagated by cuttings. Hard branch cuttings are combined with pruning before germination in spring, select 1 2-year-old robust branches as cuttings, cut them into 20 30 cm long, soak them in water for a few hours and then insert them into the seedbed 2 3, the plant row spacing is 8 10 cm, pay attention to moisturizing, and it can take root in one month. Shoot cuttings should be carried out in the rainy season, with annual robust semi-lignified shoots, the cuttings are 8 10 cm long, the upper leaf is retained, and inserted into a loose sandy substrate with an insertion depth of 3 4 cm.

Watering after cutting, shading, moisturizing, and rooting after about a month.

Clumping plants can also be propagated by branches, mostly after autumn defoliation.

Growth Habits].

It likes cool, humid and sunny climatic conditions, likes fertile neutral to slightly acidic soil, is more resistant to drought, barren and thin, resistant to semi-shade, avoids waterlogging, is resistant to cold, and grows at a suitable temperature of 15 28.

Propagation] Hibiscus can be propagated by sowing, cuttings and grafting. Cuttings can be carried out in April in combination with pruning and shaping, the cuttings are selected with lignified strong branches, 10 12 cm long, open cuttings in red soil or sandy soil, watered once a month in the morning, and it is very easy to survive.

Single-petaled hibiscus flower [cultivation].

Hibiscus has strong adaptability, is easy to grow rough, and is easy to cultivate and manage. From December to March of the following year, in the dry season in the south, hibiscus enters a semi-dormant state at this time, and the management is mainly watering and seedling preservation. From April to October, the plants can be shortened in April, and fertilizer and water management can be strengthened to promote the emergence of new shoots and make the flowers bloom luxuriantly.

Around April, cut about a centimeter from the bud axil, insert in loose soil, and preferably cover the arched shed to increase humidity and have a high survival rate.

1. Branches: Before the hibiscus branches germinate in early spring, the vigorous adult clusters are dug up, and the 3 main branches are 1 cluster, and the plants are planted according to the spacing of 50 to 60 cm.

2. Cuttings: Hibiscus flower cuttings can be carried out in combination with pruning and shaping from mid-March to early April, and the open-air cuttings are made in the red soil or sandy soil, so as to ensure that the soil is moist and the temperature is very easy to survive on the 17 to 20 sides.

3. Sowing: Hibiscus sowing and propagation is carried out in spring and April. After the fruit matures in October, the most suitable cluster tolerance is to harvest the seeds in November and December, and the seeds are peeled out after harvest and stored at low temperature, and sown or sown in April of the following spring.

4. Stripping: The horizontal branches of the wood are very easy to take root, dig a shallow ditch next to the mother plant before germination in spring, press the 1-year-old branches horizontally into the small ditch, cultivate the soil, keep the soil moist in the stripping ditch, and quickly take root and pull the shoots.

Hibiscus is a shrub flower species that is common in gardens, native to the central provinces of China and cultivated everywhere. So, how to raise hibiscus? What are the cultivation methods and precautions of hibiscus? Let's find out.

1. Soil:

Hibiscus has strong adaptability, does not have strict soil requirements, and can grow normally in poor gravelly soil or slightly alkaline soil, but it is better to have deep, fertile and loose soil.

2. Sunshine:

Hibiscus is light-loving, semi-shade-tolerant, and should be provided with sufficient during growth. Light, but not too strong, too strong sunlight should pay attention to shading.

3. Temperature:

Hibiscus prefers warm climates, with a temperature of 18 to 25 and grows best, slightly tolerant to cold.

4. Watering:

During the growth of hibiscus, attention should be paid to keeping the soil moist, long-term drought and rainless weather, attention should be paid to irrigation, and drainage should be prevented when there is too much rain.

5. Fertilization:

When hibiscus germinates, it should be topdressed in time, mainly with fast-acting fertilizer to promote vegetative growth; Apply phosphorus and potassium fertilizer 1 or 2 times before budding to promote plant bud pregnancy; 5. During the flowering period in October, top dressing was carried out twice in combination with weeding and soil cultivation, mainly phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer, to maintain the amount of flowers and tree potential.

6. Pests:

There are few pests and diseases during the growth period of hibiscus, and the main diseases are anthracnose, leaf blight, powdery mildew, etc.; The main insect pests are red spiders, aphids, demoiselles, noctuidaes, and longhorn beetles. When pests and diseases occur, pests and diseases can be cut off, and safe, efficient and low-toxicity pesticide spraying can be used for prevention and control or booby-trapping.

Precautions for the cultivation of hibiscus

Hibiscus can be transplanted in spring and autumn, and the bare roots can be dipped in mud, and some branches can be cut off appropriately, which is very easy to survive.

Pay attention to drainage and waterlogging prevention in the rainy season, pay attention to irrigation in case of drought during the flowering period, and cut off the destroyed late autumn shoots, overly dense branches and weak branches, and dead branches in late autumn to facilitate ventilation and light transmission, maintain plant shape and prevent cold and winter.

For fence planting, it is necessary to carry out 2 or 3 plastic pruning before germination in spring and during the growth period of the letter ante; If the garden is scattered, it should be dried in the spring of the second year after planting, and its base branches should be promoted, so that the 2-year-old seedlings can be cultivated into an ideal tree shape.

There are four kinds of propagation methods of hibiscus, cuttings, dividing and sowing, among which the survival rate of cuttings propagation and ramification is high, and it is the most commonly used method, when cutting hibiscus, it is necessary to select the annual and robust branches as cuttings, and the propagation of hibiscus needs to be carried out in the early spring of each year.

1. Reproduction method

The propagation methods of hibiscus flowers include sowing, cuttings, striping and branching, among which when sowing and propagating hibiscus, it is necessary to select seeds with full particles and disease-free seeds, and it should be carried out in March and April of each spring, and when striping propagating hibiscus, it is necessary to bury its branches and stems in the soil to promote the rooting of plants.

2. Propagation by cuttings

When propagating hibiscus by cuttings, it is necessary to cut a section of the current year's strong branch from the lush mother plant, and then insert the small hibiscus branch into the rooting water and soak it for 2-3 minutes to increase the rooting rate, and then the cuttings of the hibiscus can be inserted into the soil and moved to a ventilated scattered light.

3. Dividing method

The best time to divide hibiscus is in January and February in early spring every year, when dividing and propagating hibiscus, it is necessary to dig up the cluster of plants that grow vigorously in the next year, and then separate them according to the three main branches as a cluster, and then plant them in the soil, and apply well-rotted organic fertilizer as a base fertilizer in the soil.

4. Maintenance management

When maintaining hibiscus, it is necessary to place the plant in a place where it can be exposed to sunlight to promote the photosynthesis of the hibiscus and make its flowers more brilliant, and to regularly spray potassium dihydrogen phosphate or foliar fertilizer on the flowers and leaves of the hibiscus, so that the senescence of the plant is delayed and the flowering time of the hibiscus is increased.
