Sunflower is one of five major economic crops in the world, has the characteristics of salt and alkali resistance, drought resistance and barren resistance, and is also a main oil crop in northern areas of China. Sunflower is a plant of the genus Helianthus, the family Compositae. The name is obtained because the inflorescence rotates along with the sun. Annual herbage, 1-3.5 m high, up to 9 m. The stem is upright, round and polygonal, and the texture is white and thick bristles. The wide-oval leaves are usually alternate, sharp-pointed or tapered at the tip, with 3 basal veins, rough-sawteeth at the edge, rough on both sides, hair, and long-handled. The head-shaped inflorescence with the diameter of 10-30 cm grows from the top of the stem or the branch end. The total bracts are multi-layer, leafy and arranged in a covering tile shape, the total bracts are bristled, and blossom in summer, and the edges of inflorescences grow neutral yellow lingering flowers and are not firm. The middle part of the inflorescence is an amphoteric tubular flower which is brown or purple and can be strong. Oblong-shaped emascule, lignified in pericarp, gray or black, is called sunflower seed.

When planting the sunflower, in order to make the growth that the sunflower can be good develop, generally adopt the mode of artifical distance dibble seeding to sow, but this kind of working method not only efficiency is slow to also increased labour cost, the seeder of usefulness is planted to the sunflower has appeared on the market at present, but current seeder can not realize continuous accurate dibble seeding, leads to the problem that the sunflower survival rate reduces.
