Common propagation methods and matters needing attention of sea immortal

Sea immortal flowers have dense branches and bright colors, so the difficulty of artificial cultivation is not high and the adaptability is strong. Because of its strong sprouting power, sea immortals can survive the winter in the open field in Beijing. Artificial propagation of sea immortals can be done by cutting, splitting and sowing. The editor will introduce to you the common breeding methods and matters needing attention.

Sea immortal flower

I. Cuttage propagation

Sea immortals were propagated by conventional tender wood cuttings from April to May, and the semi-lignified branches growing in the same year were selected. The nursery bed can use earthen pottery flowerpots, and the matrix can be disinfected with high temperature plain sand, sieved to remove impurities, and installed in pots for backup.

Cuttings, to cut off the top of the robust new branches growing in the same year, each section is about 8cm long, cut off the heel with leaves, retain the tender leaves at the top, and all the lower leaves are cut off, if you want to prevent the cuttings from leaving too many leaves, the cuttings lose water due to transpiration, you can cut off half of the tip of each of the 3 leaves left. In order to make the cuttings heal quickly and take root early, soak the base of the cuttings for 5 seconds with 0.05%-0.1% naphthalene acetic acid aqueous solution, and insert the substrate at a depth of 4-5 cm with immersion. The row spacing of the plant is 8 cm × 8 cm. Gently shake the flowerpot after insertion to make it close. When watering, the soaking basin method can be used to water thoroughly until the surface of the basin soil is wet and taken out and placed in a moist shaded place. If necessary, use white plastic bags on the edge of the basin to create a rooting environment and microclimate, and carry out normal management after rooting and germination.

2. Separate plant propagation

After long cultivation time and clumpy shape at the base of the plant, the asexual propagation can be carried out by ramet method, and the time should be after the defoliation in autumn. When ramets, the sea immortals are taken out of the flowerpot with soil masses, removed from the attached soil, cut with a sharp knife in the gap between the branches of the rhizome, and then cut into several pieces according to 1 or 2 branches of each plant, each with fibrous roots, cut with plant ash, cultivated with culture soil, watered through and placed in a shaded and ventilated place. After 20 days, the flowerpot can be moved to the sunny place. Under the action of pot soil temperature, the root system of the plant can grow slowly, and the upper axillary buds do not germinate, which is especially beneficial to the growth of seedlings in the coming year, and will be able to blossom in the coming year.

3. Sowing and reproduction

The breeding and breeding of sea immortals should be carried out at the time of flowering. By using the method of artificial insemination, the fruits of sea immortalis were matured from September to October and stored after harvest. From March to April of the next year, the seeds were sown in a flowerpot seedling bed. The matrix can be divided into mountain soil, rotten leaf soil and sandy garden soil.

Sea immortal seeds have wings, sow in 40 ℃ warm water for 24 hours, wait for the seeds to expand and absorb enough water, sow them in the seedbed, cover the soil with 1 cm, pour water through the pot method, cover the glass, and place in a warm place, about 20 days after the seeds begin to germinate. at this time, the glass can be removed and placed in the sunny place to strengthen fertilizer and water management. when the seedlings grow 4 new leaves, they can be divided into pots and transplanting.

The skills of planting flowers in October

First, the light should be sufficient

Some light-loving woody flowers that bloom in summer, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place, so that the plants can fully receive light, so that the leaves can better carry out photosynthesis, provide nutrients in time, and promote the maturity of branches in the current year. so that it can survive the winter safely and ensure that flowers and leaves still flourish in the coming year. Potted flowers such as rhododendron, magnolia, cyclamen, poinsettia and crab claw orchid that bloom before and after the Spring Festival should also be placed in a sunny place and receive full sunshine, otherwise the flowering period will be postponed or even will not bloom. General foliage plants are more shady, can give some light properly, but to avoid noon strong light.

2. Water and fertilizer should be appropriate

In early autumn, especially in the first and middle of September, the temperature is still high and the transpiration of plants is large. Most flowers should be watered once a day or two, and the amount of water should be controlled and fertilization should be stopped from the middle to late September, so as to avoid rotting roots and growing branches and leaves. Affect overwintering. Some flowers that bloom before and after the Spring Festival, such as cyclamen, orchid, crab claw orchid, rhododendron, etc., have passed the dormant period and began to enter the peak growing season, so they should blossom continuously from autumn to the Spring Festival, and appropriately increase phosphorus and potassium fertilizer. to facilitate flower bud formation and bud flowering.

Third, pruning should be reasonable

In addition to flowers that bloom in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned in autumn and pruned at the end of autumn and early winter, so that plants can reduce nutrient consumption in winter, promote potted flowers to be strong, and bloom more in the coming year. Remove diseased branches, withered branches, over-dense branches and overgrown branches when pruning, so as to lay a good foundation for potted flowers to survive the winter.

IV. Disease and pest control should be thorough

Autumn is still the season with high incidence of diseases and insect pests, and plants are vulnerable to shell insects, red spiders, aphids, whitefly and other pests. Diseases include leaf spot, stem rot and so on. Before potted flowers enter the house, these diseases and insect pests must be treated thoroughly and never let them do harm to the house. If no diseases and insect pests are found, they can be sprayed to prevent them.

V. breeding should be timely

After the Beginning of Autumn, the temperature dropped, and some biennial grass flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., were good time to sow seeds. Sowing can be carried out from September to October, and pay attention to spraying water after sowing to keep the soil moist. There are also some woody flowers suitable for cutting in autumn, such as hanging bell crabapple, rose, geranium, jasmine, leaf flower, Phnom Penh, etc., with a higher survival rate in autumn. Perennial flowers with dense growth, such as peony and peony, should be propagated in time. For the bulb flowers that bloom before and after the Spring Festival, such as hyacinth, tulip, Zhu Dinghong, etc., we should pay close attention to the pot.

VI. The room should be entered in time

The time of entering the house of potted flowers varies according to the flowers. Fusang, poinsettia, begonia, cyclamen, jasmine, colored leaf grass, tortoise back bamboo and other warm flowers and trees should be moved indoors when the temperature is 10 ℃; hanging orchids, asparagus, one-leaf orchids, goose palm wood, rubber trees, etc., should also be moved indoors when the temperature is as low as 5 ℃. The vast majority of flowers should enter the house before Frosts Descent. Potted flowers should pay attention to ventilation indoors, and the doors and windows can be opened for ventilation and heat dissipation when the temperature is high at noon.
