Oil sunflower is also called oil sunflower, the yield per mu is generally about 300 kg, due to the different varieties of oil sunflower, the place of cultivation, and the difference in field management, the yield is different. In order to improve the yield of oil sunflower, it is necessary to select excellent varieties and cooperate with scientific management to lay a solid foundation for oil sunflower to increase yield.
1. What kind of plant is oil sunflower, oil sunflower refers to the sunflower used for oil extraction, which belongs to the oil crop with a high oil yield, and is a sunflower of the Asteraceae family native to the Americas, and the edible oil squeezed out of the oil sunflower contains high linoleic acid, which is said to be as high as about 66%. The oil yield of oil sunflower is comparable to that of rapeseed, about 45%. Sunflower oil is known as the "21st century nutrient oil".

2, the selection of high-quality and high-yield oil sunflower varieties to improve the yield of oil sunflower one of the methods, the common oil sunflower varieties are: (1) oil sunflower dwarf big head H667, the highest yield per mu of the variety can reach 350 kg, wide adaptability, drought tolerance, barrenness, saline-alkali land planting can also grow better, in Shandong, Henan, Hebei, Inner Mongolia, Yunnan, Gansu, Xinjiang, Shanxi and other places have obtained a good harvest. This variety belongs to the early-maturing variety, the growth period is about 102 110 days, the plant height is 80 120 cm, it has a strong lodging resistance, it is planted in a relatively arid place, and the yield per mu can reach more than 300 kg by using drip irrigation technology. And the quality of the oil is particularly good.
2) Oil sunflower 303 hybrid variety, 303 hybrid variety belongs to the oil medium maturity variety, the yield per mu can reach about 300 kg, with high yield, stable yield, good disease resistance of the variety, the general plant height is about 1It takes about 95 days from planting to harvesting in the spring and about 85 days after planting in the summer. The diameter of the sunflower disc can reach up to 45 cm, the yield per plant is high, and the oil content of sunflower seeds is 76%, which is a rare sunflower variety for oil.
3) GK51 oil-type hybrid sunflower variety, the variety has a growth period of about 105 days in spring and an average growth period of about 85 days in summer, in addition to high oil content and strong adaptability, in addition to strong resistance to diseases, in the planting process, there are few rusts, medium resistance to brown spot and black spot, and the resistance to Verticillium wilt, root rot sclerotinia and disc rot is also relatively good.
4) High oil 2000 oil sunflower varieties, suitable for cultivation in all arid and semi-arid areas of China, spring sowing is generally about 105 days, summer sowing is generally about 90 days, belongs to the early maturity of oil sunflower varieties. The salinity tolerance is slightly lower than that of dwarf H667.
5) American dwarf and big head, the preferential varieties of American dwarf and big head have high and stable yield, and the yield per mu is about 320 kg in normal years. It has good salt and alkali resistance, barren resistance, no rotten head, and is found by planting, the general plant height is about 80 90 cm, with a high seed setting rate, and good oil quality.
6) BS-5 oil sunflower, BS-5, also known as Kangdi No. 5, has strong adaptability, spring sowing and growth cycle is about 95 days, the average yield per mu is about 250 kg, and the plant height is 14 meters to 16 meters, this variety has strong resistance to diseases and insects, and the oil content is also high. There are many excellent varieties of oil sunflower, such as American Dwarf Giant 658, Weikui 5, DW776, American Oil King 998, Extra Early Dwarf Big Head, American Super Dwarf Big Head 567, American High Oil Oil Sunflower Hybrid Variety Dwarf Big Head 667 and so on.
