【摘要】 <正>To counteract high labor costs,mechanization has become a developing trend for rapeseed production in China.Thus,the reduction of harvest loss and maximization of profit should be evaluated.Elite rapeseed cultivar(Zhongyouza 11,Brassica napus L.) was used in two experiments from 2007-2009.Seed yields, harvest loss,and quality were compared at three harvest times under three harvest methods(i.e.,combine, indirect,and manual harvest).Optimal plant population for mechanical harvesting was determined.The更多还原
