向日葵是世界上领先的油料作物之一,在油脂生产中仪次于大豆,居第二位(见表1)。20世纪初,向日葵已成为苏联的食用油源目前,苏联仍是向日葵生产领先的国家,阿根廷、美国屈居第二和第三。与上述国家比,加拿大的向日葵生产还未引人注目。但近年来,由于高产、抗病杂交种的应用;国际市场谷物价格下跌;欧洲对向日葵油的强烈要求,加拿大向日葵业者对向日葵表现出特别的兴趣,生产一直是增加的趋势。
Sunflower is one of the world’s leading oilseed crops, ranking second in the production of fat in soybeans (Table 1). At the beginning of the 20th century, sunflower has become a source of edible oil in the Soviet Union. At present, the Soviet Union is still the leading country in the production of sunflowers. Argentina and the United States are the second and third places. Compared with the above countries, Canada’s sunflower production has not yet attracted much attention. However, due to the application of high-yielding and disease-resistant hybrids, the decline of grain prices in the international market in recent years, and the strong demand for sunflower oil from Europe, the Canadian sunflower industry has shown a special interest in sunflower production and production has always been an increasing trend.
