There are hundreds of sunflower seeds on each yellow sunflower head. These seeds are not only delicious but also contain beneficial nutrients that your body depends on. Some people worry about eating sunflower seeds because they are high in fat. Although these seeds are rich in oils, it is this healthy vegetable oil that provides your body with polyunsaturated fats.
Sunflower seeds also contain many vitamins, minerals, and phytochemicals necessary for a variety of physiological processes. It is a health benefit of sunflower seeds.
Sunflowers are temperature-loving crops and hardy crops, which have good adaptability to climatic conditions. When the ground temperature of the soil layer (0-20 cm) reaches 2°C, the seeds begin to germinate, 4-6°C can germinate, and 8-10°C can emerge and grow. When the temperature is low, the seedling time will be prolonged. In addition, seedling emergence is closely related to seed quality, moisture, oxygen, and soil composition and structure.
In many places, sunflower seeds for planting are planted in saline-alkali land, sandy land, and dry land. This is mainly because it has strong stress resistance and is more cost-effective than planting other crops. Although sunflower seeds for planting do not have strict requirements on the soil, they can grow on all kinds of soils, from fertile soil to dry land, barren land, and saline-alkali land. But planting in deep stratum, high humus content, good structure, and good water and fertilizer retention performance has greater potential for increasing production. Can obtain better output and higher economic benefits.
However, it is best to water regularly during the most important growth period around 20 days before and after flowering. Regular and deep watering can help promote root growth. This is especially helpful for taller sunflower varieties, which will bloom top-heavy flowers.
However, because they grow vigorously (can grow to 6 feet in 3 months), it is a good idea to add some slow-acting granular fertilizer to particularly poor, thin soil. The better their diet, the bigger the flower. Do not over-apply nitrogen, as this will delay flowering. Spread a layer of 2-3 inches of organic material on the soil to reduce water evaporation and prevent weed growth.
Their branches are quite fragile, especially where they connect the stems. Due to the shallow root system and large flower heads, the plants are extremely susceptible to summer wind and rain. If necessary, use a certain length of cloth or other soft materials to loosely tie the plants to the stakes.
