Abstract: In this study,98 cm ridge with double row planting was used to improve the maize yield in western Jilin Province,while 65 cm single row planting was used as control.The results showed that the productive ear per unit-area,total biomass of population,and yield in 98 cm ridge with double row planting treatment was 28.8%,13.6%,and 3.6% higher than that of control,respectively.Compared with control,the plant accumulation of N,P,and K in 98 cm ridge with double row planting treatment increased by 9.9%,7.6%,and 11.9%,respectively.98 cm ridge with double row planting treatment changed the root architecture,and increased the total root length,root surface area,average diameter,root volume,and number of branches.Additionally,98 cm ridge with double row planting treatment also increased the leaf area index in the top layer by 20.6%,but reduced transmission in the top layes by 15.3%.The advantages of 98 cm ridge with double row planting pattern in improving corn yield deserve further investigation.
