“油见油,三年愁”,是指油料作物在生产中不能重茬连作,三年之内不能再种同样的油料作物。这是我国农民在长期的生产实践中总结出来的十分宝贵的经验。辽宁省农科院栽培所近年做了向日葵轮作试验,也证明了这一经验的正确。 “Oil see oil, three years worry”, refers to the oil crop can not be cropping continuous crop production, within three years can not be the same kind of oil crops. This is a very valuable experience summed up by our peasants in long-term production practices. Liaoning Provincial Academy of Agricultural Sciences in recent years made a sunflower rotation test, but also proved that this experience is correct.
