What is the correct planting method of Gerbera jamesonii?

Friends who like flowers don't know much about African chrysanthemum cultivation! To this end, I have compiled "Chrysanthemum Planting in Africa" for your reading.

Growth habit of African chrysanthemum

Gerbera is native to Mexico. I like a warm, humid and sunny environment. The optimum growth temperature of chrysanthemum is 15 ~ 20℃, and the winter temperature is not lower than 5℃. When the temperature is above 30℃ in summer, the plants grow in vain, with loose stems and leaves and few flowers. It can grow below 10℃, but the growth rate is slow and the growth period is prolonged.

Gerbera jamesonii likes humidity and is drought-tolerant, especially in summer, when there is too much water, the stems and leaves grow vigorously, which affects the plant shape and flowering. It is necessary to strictly control the water content and dry it slightly when cultivating chrysanthemum in high temperature period.

Gerbera jamesonii is a light-loving plant with abundant sunshine.

The growth of Ju Shou is very favorable. The plants are short and strong with bright colors. Insufficient sunshine, soft and slender stems and leaves, few and small flowers. Chrysanthemum is sensitive to the length of sunshine, and short sunshine treatment (9 hours) can blossom early.

Gerbera jamesonii has low requirements on soil, and fertile sandy loam with good drainage is better.

Method for planting African chrysanthemum

① Seeding and propagation: The sowing temperature should be suitable in spring, and attention should be paid to avoiding light.

It is better to sow gerbera in spring. At this time, the sunshine is not strong and the temperature is suitable. Because Gerbera jamesonii seeds are afraid of light, attention should be paid to covering vermiculite on the soil surface after sowing, so as to prevent light from penetrating into the soil and affecting the germination and growth of seeds. Generally speaking, the soil where seeds grow can germinate in a week at room temperature and bloom in about three months.

(2) Cutting propagation: Cutting takes root quickly in summer with high survival rate.

Cut a tender branch about 10 cm from the robust main branch of Gerbera jamesonii to make cuttings, remove the leaves below the Gerbera jamesonii cuttings, and insert them into potted soil after oblique cutting at the base. After proper watering and shading, Gerbera jamesonii can take root in about half a month. The survival rate of cutting is relatively high, and it blooms quickly, about one month after rooting.

③ Seedling raising techniques.

Seedling raising in small arch shed: the leeward and sunny places in the east-west direction are covered with plastic film for insulation.

Build a small arch shed for Gerbera jamesonii before seedling raising, preferably in the leeward and sunny place in the east-west direction, and the film covered by the small arch shed should have certain thermal insulation. The height of the arched shed should not exceed 60 cm as far as possible. If it is too high, it will be very inconvenient to manage the weather in windy and rainy days.

Selection of fertile soil: the soil should be loose and breathable, and the bottom should be sprinkled with base fertilizer.

Although Gerbera jamesonii does not pick up soil, loose and breathable soil will be more conducive to its growth. We can dig deep into the soil, sprinkle a certain amount of base fertilizer after the soil becomes fine and soft, and then dig deep so that the base fertilizer can be evenly spread on the bottom of the soil.

Sterilization and disinfection of seeds: after the seeds are dried, soak them in warm water for a period of time for sterilization and disinfection.

First, select some plump gerbera seeds for sowing and seedling raising. After these seeds are dried in the sun and soaked in warm water for several hours, they can effectively sterilize and accelerate germination. Then, the seeds are washed with clear water and dried before sowing.

Seeding and seedling management: properly adjust the ambient temperature and pay attention to ventilation after emergence.

The seeds of African chrysanthemum may germinate one week after sowing. Pay attention to the temperature of the surrounding environment after emergence, which should not be higher than 30 degrees, otherwise the seedlings will be burned or even rotted, and it is best to keep it at about 25 degrees. After the temperature is appropriate, pay attention to ventilation to ensure the circulation of fresh air. When it is windy and rainy, there is no need to ventilate again to avoid wind and rain damaging the normal growth of seedlings.

④ Transplantation technology

When Gerbera jamesonii grows to a certain height, it will have three or four pairs of true leaves when it grows to 15cm. At this time, we can transplant gerbera seedlings. As the seedlings vary in size, we need to transplant them to branches when necessary. Pay attention to cover the seedlings with plastic film after transplanting, and water them during the period. Adequate water can make Gerbera jamesonii better enter the slow seedling stage and also play a positive role in promoting its growth.

Planting characteristics of African chrysanthemum

1, Xiguang: When there is no water shortage, it grows stronger and stronger, grows faster and faster, and blooms more and more;

2, like fertilizer: like dwarf cattle, if you want to bloom more, fertilizer should keep up;

3, drought tolerance: fleshy roots developed, strong water absorption, but avoid waterlogging, which is the main reason for her death. Proper water control is the safest to prevent wilting (discussed in detail later);

4. Temperature: The optimum flowering temperature is 15-30 degrees, and the flowering will last within this range. The ultimate tolerance temperature is 5-40 degrees, and the growth will stop below 7 degrees. In high temperature season, the growth will slow down, but it will not weaken, and it will blossom sporadically, so the full flowering period is in March-May and 9-165438+1October.

5. Pests and diseases: This is the fatal weakness of Gerbera jamesonii and all compositae plants. Anyone who has raised chrysanthemum knows that chrysanthemum is a magnet for insects, so it is necessary to find it early and treat it early. The main diseases are fungal root rot and crown rot, commonly known as rotten roots and stems. Attention to watering methods can be avoided.

6. Flowers: The flower diameter of conventional varieties is 8- 12cm, and the colors cover all colors except blue and purple. The color is warm, nice and warm. A single flowering period is very long, even the vase can last for more than half a month, so it is suitable as a cut flower.
