去年我社共种油菜1,876亩,比1974年播种面积扩大3倍。在种植形式上进行了改进,采用油菜与玉米宽幅间作,油菜籽平均亩产103斤,比1974年增产52%。油菜、玉米的间作带各为9.6尺,玉米种6行,油菜种10行。曲菜的行距为0.8尺,油菜、玉米的两个边行的距离勾2尺(油莱留1.2尺,玉米留0.8尺)。王米的行距为1.6尺(见图)。加大边行距离可避免因 Last year, a total of 1,876 mu of rapeseed was grown, three times more than the sown area in 1974. In the form of planting has been improved, using rapeseed and corn wide intercropping, rapeseed average yield 103 kg, 52% increase over 1974. Rape, corn intercropping with each of 9.6 feet, 6 lines of corn, rape 10 lines. The distance between two rows of rapeseed and maize is 2 feet (1.2 meters for Levin and 0.8 feet for corn). Wang meters line spacing of 1.6 feet (see photo). Increase the distance between the border can be avoided
