The method of sowing and propagation of star flower

Starry flowers, colors 5 split into five-pointed stars, hence the name five-star flowers. Dozens of five-star flowers gather into clusters, which are very gorgeous and pleasing to the eye. Its drought resistance, high temperature resistance, long flowering period, a variety of colors, suitable for potted plants and layout of flower beds, flower beds and landscape layout.

Starry flowers can also be made into potted plants to be placed indoors, which can not only add beautiful colors to the indoor environment, but also bring a strong natural atmosphere to the indoor environment. Starry flowers are suitable to be placed on people's balconies or windowsills. While beautifying the environment, they can also play a role in purifying the air. When breathing, they can decompose and absorb a variety of harmful substances in the air, allowing people to breathe purer air.

How to sow and reproduce such a widely used star flower? The following is an explanation for you. I hope it will be helpful for you to plant star flowers.

I. conditions for sowing and raising seedlings

1. Seedling raising facilities: acupoint tray.

2. Medium: use the breeding medium which is rich in humus, good drainage and aseptic, such as "Zhuangmiao No. 3" of Nongyou Seedling Company.

3. Ph value: 6.5-6.8.

4. EC value: 0.75ms/cm.

5. Light: seeds need light to germinate, so they do not cover the soil. But the light is appropriate and the temperature is controlled.

6. Temperature: the optimum temperature for germination is 20-30 ℃.

7. Humidity: keep the relative humidity in the air at 100% until the cotyledons grow out, so as to avoid the seedling medium being too wet. At the stage of seedling growth, the relative humidity should be reduced to 50% to prevent leaf diseases.

Second, the steps of sowing starry flowers

1. Sow the seeds in the hole plate or sow the seedlings on the plate, sowing one seed in each hole. The hole size should be 1.5-2 cm.

2. Germinate about 10-14 days after sowing, control the growth temperature at 23 ℃-26 ℃, and keep the relative humidity in the air at 100% until the leaves grow out.

3. During germination, sufficient watering is needed to accelerate the dissolution of the outer layer of powdered flowers and promote germination.

4. The flowers can be transferred to the pot 7-9 weeks after sowing, and the best diameter of the flowerpot is 10-15 cm. The cultivation medium is aseptic, slightly fertilizer-containing and well-drained peat soil, and the pH value is 6.5-6.8.

3. Main points of sowing skills

1. Before sowing, fully balanced fertilizer and slow-release fertilizer were applied in the substrate to keep the soil fertile and provide sufficient nutrients for the seeds.

2. In the stage of seedling growth, the relative humidity should be reduced to 50% to prevent leaf diseases.

3. If the light is kept properly during germination, the new buds will grow neatly and the quality will be higher.

4. With the growth of seedlings, the illuminance should be increased appropriately and the temperature should be controlled.

5. After germination, the seedlings should be exposed to sunlight as soon as possible to avoid overgrowth and promote the rapid growth of plants.
