1, sowing and breeding method

After 2-3 days, when the perianth cracks, the bud matures and the stigma secretes mucus, it is the time for pollination. When pollinating, dip the stamen pollen with a new brush and gently shake it on the stigma of the pistil. In order to improve the seed setting rate, the seeds can be pollinated 1 time at 9- 10 in the morning and 2-3 in the afternoon, respectively, and the seeds will mature after about 8-9 months. When the peel gradually changes from green to deep purple, the ear can be cut and the seeds peeled after 10-20 days.

Clivia likes slightly acidic soil, and the suitable pH value is 6-6.5. The time requirement for breeding Clivia by sowing method is not strict. Sowing can be done in spring, autumn and winter, but temperature is an important factor. The best sowing temperature is 20-25℃ to meet the temperature requirements of budding embryos.

2, ramet propagation method

When dividing plants, first take the mother plant of Clivia out of the pot, remove the host soil, and find out the buds of the organs that can be divided into plants. If the daughter plant is born on the outer edge of the mother plant and the plant is small, one hand can grasp the bulb part of the daughter plant and the other hand can grasp the base of the daughter plant and tear it off, so as to separate the daughter plant from the mother plant; If the plant is strong and difficult to break, you should cut it off with a prepared sharp knife.

Never break it to avoid damaging the seedlings. Immediately after cutting off the offspring, the wound should be smeared with dry charcoal powder to absorb the main liquid to prevent decay. Next, plant the offspring in flowerpots. When planting, the planting depth is to bury pseudobulb at the base of the seedling, and the part close to the seedling should be slightly higher, and covered with sterilized sand. Water is poured once after planting, and a layer of culture soil is covered when the wound heals two weeks later. Generally, it takes 1-2 months to produce new roots and 1-2 years to blossom.

Precautions:

1, disease diagnosis and treatment

Due to unsuitable cultivation conditions, Clivia often causes the invasion of germs and diseases, which affects its ornamental value and even leads to plant death. Therefore, it is very necessary to diagnose the diseases of Clivia early and take preventive measures in time.

2, rotten root treatment

When Clivia was branching, the wound was not disinfected and was infected by bacteria. Or too much watering, poor soil permeability, too much fertilization and application of immature raw fertilizer are all common causes of root rot of Clivia. If the individual roots of adult Clivia rot, it will show as a leaf that is dry and sharp, black and scorched. Find out the reason, add and overcome, and stop the root rot from continuing.

3, white silk disease

Before cooking, the culture soil should be disinfected. A relatively simple method is to leave the culture soil at 60℃ for 24 hours. Always pay attention to the soil surface, pick out the white bacteria line and burn it, and sprinkle some lime powder around the diseased area for disinfection; At the early stage of the disease, 500 times of 50% carbendazim wettable powder was poured on the soil around the stem base of the plant, once a week, 2-3 times.

Extended data:

Clivia, also known as Lycoris flagelliforme and Lycoris macrophylla, is an ornamental flower of Clivia in Amaryllidaceae. Originated in South Africa. It is a perennial herb with a flowering period of 30-50 days, mainly in winter and spring, and it also blooms from New Year's Day to Spring Festival. It is a semi-negative plant, which likes cold and avoids high temperature.

The optimum growth temperature is 15-25℃, and the growth stops below 5℃. I like thick, well-drained soil and moist soil to avoid dry environment. Clivia has high ornamental value, and it is often potted in greenhouse in China for ornamental purposes. Propagation of ramets or seeds. The same effect is still Clivia, which is cultivated in greenhouses all over the country and has various colors. Clivia has a life span of decades or longer. Clivia is the city flower of Changchun.

Clivia is native to the tropical region of southern Africa and grows under trees, so it is neither afraid of heat nor cold. It likes semi-cloudy and semi-humid environment and is afraid of strong direct sunlight. The optimum temperature for its growth is between 18-28℃, and its growth is inhibited when it is lower than 10℃ and higher than 30℃. Clivia likes ventilated environment, deep, fertile and loose soil, and is suitable for growing in loose and fertile slightly acidic organic soil. Clivia is a famous greenhouse flower, suitable for indoor cultivation.

There is a certain correlation between roots and leaves. When new roots and leaves grow, new leaves will come out and the roots will be destroyed (rotted or dried by stagnant water, etc.). ). As long as the leaves don't wilt, keep the soil moist during maintenance, and remember not to be too waterlogged and overworked, then the roots will regenerate and the plants will survive (with proper maintenance, new roots will grow in about 10 days). Damage to the blades will also affect the roots.

Clivia usually blooms once a year and usually has more than 12 leaves. If the indoor planting temperature is suitable, flowers can bloom around the Spring Festival. Clivia, known as the flower of wealth, usually blooms once a year, and rarely blooms twice a year when it grows up, but it is rare to bloom three times.
