摘　　要：通过对两种播种方式进行多点比较试验,结果表明,在三熟制产区,选择早熟高抗油菜品种栽培,免耕撒播比机耕撒播产量略减或持平,可节约成本975.0～1050.0元·hm-2,提高效益540.0～990.0元·hm-2,是值得推广的一种油菜轻简化栽培模式。Multi-location comparative experiments of two kind of sowing methods were carried out. The results showed when early mature and strong resistance rape varieties were planted in triple-cropping system region, the yield of no-tillage broadcast sowing were slightly low or had little different than tractor ploughing broadcast sowing. The cost could be saved 975.0-1 050.0 yuan·hm^-2 and the benefit could be increased 540.0-990.0 yuan·hm^-2, which was worth popularizing as a pattern of rape simplified cultivation.
