为了探索油菜在带植土内进行套种的可行性,增加经济效益,合川县农技站于1985年在带植地麦、玉、苕中套种一熟油菜,进行了多点试验,结果证明:带植土内套种油菜是可行的。据16个区点两年试种示范面积47.81亩统计,总产油菜籽4532.39斤,平均亩产94.8斤。其中7.86亩,平均亩产达到104.7斤。带植土内套种油菜每亩获得的经济效益是,如每斤油菜籽按中等收购价0.455元计算,亩收94.8斤,折人民币43.13元。扣除每亩种子、用工、肥料等费用26.10元,带植土种一亩油菜的纯收益是17.03元。对国家、对广大农户和城乡人民都有好处。

According to the statistics of 47.81 mu demonstration area for two years in 16 districts, the total output of rapeseed was 4532.39 kg, with an average yield of 94.8 kg. Of which 7.86 mu, the average yield reached 104.7 kg. With ramets planted interplanting rape per acre obtained economic benefits, such as per kilogram of rapeseed at a moderate purchase price of 0.455 yuan calculation, mu received 94.8 pounds, folding 43.13 yuan.
