First, choose seeds.
Choosing high-quality sunflower seeds requires full color, firmness and flawless surface. If you are not sure about the quality of the seeds, you can soak them first. Soak the seeds in warm water at 50℃, take them out after 30 minutes, wrap them in clean cloth and put them in the dark, and observe them for 2 to 3 days. If the seeds show signs of germination, the quality is good.
Second, soil preparation
Sunflower seeds do not require much soil, but it is best to use loose, fertile and well-drained soil. Before planting, the land needs to be cultivated to remove weeds and large pieces of soil. Apply an appropriate amount of organic fertilizer on the land, such as decomposed compost or livestock manure.
Third, sow.
Sowing is usually carried out in spring or summer, and soil disinfection can be carried out before sowing. When sowing, the seeds are evenly spread on the soil surface, and then a layer of soil is gently covered, and the covering thickness is generally about twice the thickness of the seeds. For sandy soil, seeds can be buried shallowly, and for heavy soil, seeds need to be buried deeply.
Fourth, on-site management
Sunflower seeds like an environment with abundant sunshine, suitable temperature and suitable moisture. Weeding, loosening soil and watering are needed in time during the growing period to ensure the healthy growth of crops. Be careful not to let the soil be too wet or too dry, and also pay attention to prevent the occurrence of pests and diseases.
