Seed treatment

Due to the characteristics of hard seeds and bright waxy surface, it takes months to emerge under normal circumstances. Therefore, in order to make it emerge quickly, before sowing, you need to gently rub the layer of wax with dry fine sand that is exposed to the sun or heated to achieve the effect that the seed coat is slightly broken, and then immerse it in warm water at 38 ℃. After soaking for more than a day, take out the seeds, wrap them with coarse cloth, and put them in a warm and moisturizing place. When the planting expands and is slightly dried, you can sow. The suitable temperature for sowing is about 20-28 ℃

Sowing attention

The surface of the flower seed is covered with a thin layer of culture medium, which is about 1-3 times the diameter of the flower seed. If the seed is buried too deep, it will be difficult to sprout. Spray water can be used in a proper amount. It is better to cover the top of the flower pot with plastic paper, so as to reduce the evaporation of water. Put the flower pot in the shade to avoid light, but pay attention to opening it for 15-20 minutes every day to breathe. Flower seeds generally germinate in about 8-10 days. However, sometimes it may be affected by factors such as temperature changes, and the normal germination time of seeds will change, so there is no need to worry too much

Budding attention

When the first pair of cotyledons on the bud unfold symmetrically, it is necessary to remove the cover immediately and then move it to a sunny place, but avoid direct sunlight, pay attention to temperature changes and do not water too much. When the first pair of cotyledons are green and fully expanded, it is necessary to gradually increase the illumination time under direct light. When the first pair of true leaves grow, they should be able to get direct light all day while keeping the culture medium slightly moist. When the second pair of true leaves grow, it shows that sowing has been basically successful. As long as we pay attention to temperature and water management at ordinary times, dancing grass can thrive< span>
