摘　　要：为探索适合辽宁中晚熟稻区豌豆-水稻复种栽培模式,以科豌7号、科豌6号早熟豌豆品种为试材,开展不同播期下的栽培模式试验,即:3月27日拱棚播种(A),3月27日覆膜播种(B),3月27日裸地播种(C)为对照,4月10日裸地播种(D),探究其对农艺性状和产量的影响并分析了综合收益。结果表明:与对照相比,两个品种拱棚播种(A)和覆膜播种(B)通过提高出苗速度进而缩短生育期,增产效果显著,并以拱棚播种产量最高。延迟播种(D)虽缩短了各阶段生育进程,但无法在有限茬口期正常成熟,产量最低。不同模式下,科豌7号、科豌6号的综合经济效益均以3月27日覆膜播种(B)最高,分别比对照增加479.49元/667 m^(2)和172.19元/667 m^(2)。In order to explore the pea-rice multiple planting mode suitable for the middle and late maturing rice area of Liaoning Province,the early pea varieties Kewan-7 and Kewan-6 were used as test materials to carry out cultivation mode experiments under different sowing dates.The treatments were designed as arched plastic greenhouse sowing in March 27th(A),film mulching sowing March 27th(B),outdoor sowing in March 27th(C)CK outdoor sowing in April 10th(C),Explored its impact on agronomic traits and yield,and analyzed comprehensive benefits.The results showed that compared with the control,treatment(A)and(B)of two varieties shortened the growth period by increasing the emergence rate,resulting in a significant increase in yield.Treatment(A)had the highest yield.Although processing(D)shortened the growth process at each stage,it was unable to mature normally during the limited crop period,resulting in the lowest yield.The comprehensive economic benefits of Kewan-7 and Kewan-6 under different modes were the highest in treatment(B)on March 27th,with an increase of 479.49 yuan and 172.19 yuan respectively compared to the control.
