How to raise seedlings of zinnia?

1. Sowing seeds

The sowing time is usually controlled from June to July, and there are also autumn sowing experiments. Due to the influence of temperature and other factors, autumn sowing is generally not adopted, because it has a certain impact on flower color and plant morphology. The sowing medium is a loose artificial medium, and when the conditions permit, the seedlings can be sown in the base bed, sowing on the tray or raising seedlings on the hole tray. After disinfection, the sowing medium can be kept for 4 days at 23 ℃.

2. Raising seedlings

Three days after sowing, the radicle will be shown, and the culture medium should be relatively dry, but it is very important to maintain water and sufficient oxygen content around the seed at this stage, so after sowing, covering a thin layer of coarse vermiculite is very beneficial to seed germination, and the thickness of the cover is invisible. For open seedlings, sunshade nets must be covered to ensure humidity and lower temperature, and fertilization is not needed at this stage.

3. Soil requirements

The main root of zinnia grows to 2 cm, the cotyledons expand, the first pair of true leaves begin to grow, and the seedlings can gradually see light. Fertilization can be started, and 0.05% urea is generally used to promote vegetative growth. Keep the soil relatively moist, neither too wet nor too dry, too wet can easily lead to disease, too dry will cause seedlings to wither.

4. Seedling management

When the seedlings enter the rapid growth stage, the water management should be strengthened and the cycle from dry to wet to dry should be carried out, which is beneficial to the growth of seedling roots and avoid excessive growth. At this stage, attention should be paid to the prevention and control of diseases and insect pests and proper application of compound fertilizer. When the conditions permit, the temperature of the medium and environment should be properly reduced to about 20 ℃. However, under the protective condition of sowing in the foundation bed, the temperature during sowing is difficult to control. Full light environment is also needed at this stage, otherwise it is easy to lead to excessive growth of seedlings. According to the growth of seedlings, we should properly control water content and pay attention to the ventilation of the environment to prevent diseases.

5. Transplant

The root system is well formed and overgrowth occurs when there are three pairs of true leaves. B9 should be sprayed immediately to control the height. The temperature and humidity requirements are the same as in the third stage, and after the hardening stage, the seedlings can be transplanted into flowerpots.
