辽宁省种植烤烟历史悠久,建国后发展较快,1952年就有17个县种植烤烟,种植面积曾达30万亩。50年代烤烟产量较低,一般在130斤上下。60年代优质和高产品种搭配种植,烤烟产质均适应卷烟工业和消费者的要求。70年代由于高产品种单一化,烟叶产量高,品质差,不能适应新的要求。辽宁省气温较低,无霜期短,在利用有利气候条件发展烤烟生产方面,群众积累了不少
Liaoning Province has a long history of planting flue-cured tobacco and has developed rapidly since the founding of the People’s Republic of China. In 1952, flue-cured tobacco was planted in 17 counties and the planted area reached 30 million mu. Flue-cured tobacco production in the 1950s was low, generally about 130 pounds. In the 1960s, high-quality and high-yielding varieties were planted with plants, and the quality of flue-cured tobacco was adapted to the needs of the cigarette industry and consumers. 70s due to a single high-yield varieties, high yield tobacco, poor quality, can not meet the new requirements. Liaoning Province, the temperature is low, frost-free period is short, the use of favorable climatic conditions for the development of flue-cured tobacco production, the masses have accumulated a lot
