摘　　要：2006～2008年,研究了马铃薯下茬复种辽杂19的产量和经济效益,并与辽杂11、大豆、白菜、萝卜等下茬作物的经济效益比较。结果表明,马铃薯复种辽杂19比辽杂11、大豆、白菜、萝卜作下茬作物有多方面优势,在这一模式下,最多可收马铃薯45290.6kg/hm2、辽杂19高粱11288.5kg/hm2,经济效益可达近3万元/hm2,应用前景良好。The multiple cropping systems of Liaoza 19 with other crops or varieties, such as Liaoza 11, potato, soybean, cabbage and radish were investigated and compared during 2006 - 2008. The results indicated that cropping with potato could achieve more production and better benefits than with other crops. Under this cropping system, the potato yield could reach at 45 290.6kg/hm^2, and Liaoza 19 yield could reach at 11 288.5kg/hm^2. The economic benefits could be reached at as higher as 30 000 Yuan/hm^2 （RMB）, showing great perspectives in its application.
