Sunflower is also called sunflower and sunrise flower. You must know the four growth stages of sunflower, that is, seedling stage, bud stage, flowering stage and maturity stage. So how to manage sunflower cultivation in stages? Today, I'd like to introduce the management of four growth stages of sunflower.
Management of Sunflower Growth Stage
Seedling stage
At this stage, water once a week, fertilize once a half month to ensure sufficient sunshine.
Bud stage
Budding stage is the most vigorous stage in sunflower life. During this period, sunflower needs the most fertilizer and water. If this stage can not meet the needs of sunflower for water and fertilizer, it will seriously affect the yield of sunflower.
Blooming period
Flowering period refers to the period from glossy flower to tubular flower. In this stage, the sowing date of sunflower should be adjusted, fertilization and watering should be selected at the right time, pest control, and artificial pollination can be used to improve the seed setting rate of sunflower.
Mature period
At this stage, there are different varieties of sunflower. About 15 days after anthesis and pollination is the stage of seed formation. In this period, it is best to place it in a sunny environment with a large temperature difference between the day and the liquid, and keep the appropriate soil moisture.
