1、 Do you need sunshine

Sunflowers like sunshine very much. Sunshine is a key factor. Germination requires a certain amount of sunshine. Seeds can be buried in the soil, watered and placed in a place with good sunshine. In a warm growth environment, they can sprout and grow seedlings in about 5-7 days. After the sprouts grow, they also need sunshine. They still need to be exposed to light at all times, so as to promote the sprouts to grow higher and higher, and the leaves will gradually increase. However, the time of sunshine cannot be too long, and strong light for a long time is also stimulating. If there is no sunshine all the time, there will be problems in the growth of sunflowers, and the seedlings will be difficult to be strong

2、 The role of sunlight

1. Before germination: before germination, put it in a sunny place, which can raise the overall temperature and promote germination and growth as soon as possible

2. Seedling stage: after sprouting and growing seedlings, an appropriate amount of sunshine can make the seedlings strong, prevent overgrowth and promote growth as soon as possible

3. Mid growth period: if there is sufficient sunshine at this time, it can promote the vigorous growth of stems and leaves, and ensure normal flowering and pollination

4. Late growth stage: in the late growth stage, it is the period of growing seeds. At this time, maintaining sufficient sunshine can promote the development of seeds
