Effect of Cultivation Mode on Yield and Benefit of Previous Crop Pea in Liaoning Rice Area
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.
