黑龙江省是大豆主产区，近年来由于受商品经济的冲击，大豆种植面积日益扩大，从而使生产上出现了大面积的大豆重迎茬现象造成大豆单产降低，品质变劣，针对这种情况，我们于1993－1994年进行了大豆品种间轮作的试验，以减少因大豆重迎茬而带来的损失。试验条件与设计选择地势
Heilongjiang Province is the main producing area of soybean. In recent years, due to the impact of commodity economy, soybean planting area is expanding day by day. As a result, large-area soybean replanting and stubble cropping resulted in the reduction of yield and quality of soybean. In view of this situation In 1993-1994, we conducted tests on the intercropping of soybean varieties in order to reduce the losses due to the replanting of soybean.
