摘　　要：2003-2005年度在贵州省安顺市西秀区七眼桥镇用油研7号、油研10号、油研8号等进行油菜撒播高产、高效的轻型配套栽培技术试验示范,面积分别为3.41 hm2和100 hm2,平均单产分别达164.1 kg/667m2和133.2 kg/667m2。其中,2004年验收的10块地（测量面积合计0.685 hm2）的撒播油菜平均产量为158.9 kg/667m2,最高产量达210-230 kg/667m2;2005年验收各类田块19块（面积合计1.159 hm2）,单产105-206.3 kg/667m2。除去人工（每个工按15元计）、牛工（每个工按30元计）、物资投入外,667m2纯收入达189.57元,单个劳动力的产值达35.83元,比同地育苗移栽分别高131.11元/667m2和17.83元/个,比当地传统的苦油菜（芥菜型）撒播栽培增收175.72元/667m2。Youyan 7,10 and 8 were planted by the broadcast cultivation technique on 3.14 ha and 100 ha of fields in Xixiu district,Anshun for demonstration and the average yields were 164.1 kg/667m2 and 133.2 kg/667m2 respectively during 2003～2005.The average yield in 0.685 ha field was 158.9 kg/667m2 and the highest yield was up to 210～230 kg/667m2 on-spot check in 2004.The yield in 1.159 ha field was 105～206.3 kg/667m2 on-spot check in 2005.The pure income/667m2 and output value per labor by using the broadcast cultivation technique were 189.57 yuan and 35.83 yuan,131.11 yuan and 17.83 yuan higher than those by using the transplanting seedling technique respectively and 175.72 yuan higher than mustard rape by using the broadcast cultivation technique in the same location.
