Introduction to the propagation method of pink purple double hibiscus

Pink purple double hibiscus has strong adaptability, and the difficulty of artificial cultivation is not high. It is cultivated in the north and south of our country. Artificial propagation of pink-purple double-petal hibiscus can be done by means of plant division, cutting, sowing and striping.

Pink purple double hibiscus

I. split-plant propagation

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 × 60cm.

2. Cutting propagation

Cuttings can be carried out from mid-March to early April combined with pruning and shaping, and cuttings are selected for Lignification, with a length of 10-12 cm. Open-air cuttings are cut in red soil or sandy soil to ensure that the soil is moist, but the survival rate is low; it is best to be cut in a nursery bed with plastic film moisturizing, and the temperature is between 17 ℃ and 20 ℃.

Choose 1-2-year-old strong, unsprouted branches. Cut a small piece of 15~20cm, prepare a stick when cutting, insert a small hole in the seedling bed according to the plant and row spacing, and then insert the pink-purple double hibiscus branches to compact the soil and 10~15cm into the soil, that is to say, the depth of the cuttings should reach 2gam3, and water should be filled immediately after cutting. There is no need to apply any base fertilizer when cutting.

3. Sowing and reproduction

It usually takes place in spring in April. After the fruit matures in October, it is most suitable to collect seeds from November to December. After harvest, the seeds are stripped and stored at low temperature, and then sowed or sowed in April. After defoliation in autumn or before sprouting in early spring, the sprouting plants in the rhizosphere of the plant are dug up and planted separately. Before planting, the root can be trimmed properly, and the aboveground parts can be heavily cut. Pink purple double hibiscus has strong adaptability, simple cultivation, extensive management, and generally allows it to grow freely. However, in order to improve its ornamental effect and make its flowers blossom and colorful, necessary management should be given. Pink-purple double hibiscus blossoms on new branches of the same year and can be pruned properly after falling leaves in autumn. When pruning, it is appropriate to combine sparse pruning with short cutting, moderate short cutting of long branches, thinning of dense branches and weak branches, so that nutrition is concentrated and plump. In the middle and late April after spring plant germination, fertilizer should be applied once and watering in real time to ensure sufficient fertilizer and water in the soil. When the pink purple double hibiscus is planted, the base fertilizer should be applied in the planting hole, and there will be no more fertilizer in the future. From spring bud sprouting to summer flowering, watch the weather irrigate for 2 or 3 times. Drainage and waterlogging should be carried out in the rainy season. Pour water once before frost after autumn to prevent frost. Late summer and early autumn should not be irrigated, lest autumn shoots grow too tender and reduce cold resistance. When the seedlings under 6 years old are overwintering, cold prevention measures should be taken, such as root soil cultivation and so on.

4. the technique of pressing and raising seedlings

Because the transverse branch of wood is very easy to take root, dig a shallow ditch next to the mother plant before spring germination, press the one-year-old branch horizontally into the trench, cultivate the soil, keep the soil moist in the trench, and root and shoot quickly. After falling leaves in autumn, the strips are cut from the base, and then the seedlings are dug up and divided into seedlings.

Culture method of pink purple double hibiscus is pink purple double hibiscus poisonous

Pink purple double hibiscus has fast growth rate and strong adaptability, and is cultivated all over the north and south. Pink purple double hibiscus has a strong air purification ability, that pink purple double hibiscus how to cultivate it? Is pink purple double hibiscus poisonous? Let's get to know each other.

I. Culture method of pink purple double hibiscus

Pink purple double hibiscus can be cultivated in a single row with a ridge spacing of 110-120 cm and a plant spacing of 50-60 cm with planting holes or trenches in the middle of the ridge. When transplanting hibiscus, it is necessary to apply sufficient base fertilizer into or in the planting ditch, usually with garbage soil or rotten barnyard manure and other farm manure, combined with a small amount of compound fertilizer, transplanting should be carried out during the dormant period of seedlings or in the rainy growing season. Part of the branches and leaves should be cut off when transplanting to facilitate survival. After planting, the fixed root should be watered once, and the soil should be kept moist until it survives.

There are few diseases and insect pests during the growth period, the main diseases are anthracnose, leaf blight, powdery mildew and so on, and the main pests are red spiders, aphids, coir moths, nocturnal moths, longicorn beetles and so on. When diseases and insect pests occur, the branches of diseases and insect pests can be cut off, and safe, efficient and low-toxic pesticide spray control or trapping can be selected. Attention should be paid to early prevention and control, to avoid pesticide application during the flowering and harvest period, and to ensure that the harvested hibiscus flowers are not contaminated by pesticides.

Common leaf spot and rust damage, sprayed with 65% Dysen zinc wettable powder 600 times. Pests include whitefly and beetle, mainly aphids, as well as inchworm and leaf roll moth, which can be sprayed with 1000 times omethoate EC. The safe deworming method for the environment is to use diluted detergent.

Is pink and purple double hibiscus poisonous?

Pink purple double hibiscus is a variant of hibiscus of Malvaceae. It is distributed in Shandong and other places of Chinese mainland, but it has not been introduced and cultivated artificially at present. It is not only an excellent plant resistant to smoke and dust, hydrogen fluoride and other harmful gases, but also a good tree species for beautifying, greening and purifying the air. At the same time, hibiscus has strong resistance to harmful gases such as dioxin disulfide and chloride, and has a strong dust retention function, so it is the main greening tree species in polluting factories.

These are the cultivation methods of pink-purple double hibiscus and the poisonous pink-purple double hibiscus. Pink-purple double hibiscus combines beautification, greening, purification and integration, so you can raise some in the courtyard at home.

2. Key points of culture of pink purple double hibiscus

Pink purple double hibiscus is highly adaptable and is cultivated all over the north and south. Even if you like the sun, you can withstand half the shade. It can survive the winter in open field in most areas of North China and Northwest China. It can grow in viscous heavy or alkaline soil, but avoid drought. During the growing period, it needs timely and appropriate watering, and often keeps the soil moist. Hibiscus management is relatively extensive and resistant to pruning.

Pink and purple double hibiscus is properly watered during drought, and a little thin liquid fertilizer is applied in the peak growing season, and only a little pruning is done every year to make it ventilated and transparent. Keep the soil moist during the growing period. Fertilization was applied once before sprouting in spring, and phosphate fertilizer was applied twice during flowering period from June to October. Control plant shape and posture by pruning, preferably pruning to 2 feet high in winter and pruning again in March, but not too much. Transplantation should be carried out after defoliation. Part of the branches and leaves should be cut off when transplanting to facilitate survival. After planting, the fixed root should be watered once, and the soil should be kept moist until it survives.

The above are the breeding methods of pink-purple double hibiscus and the main points of cultivation of pink-purple double hibiscus. After understanding the breeding methods, you can breed pink-purple double hibiscus by yourself, making it a beautiful scenery.
