Abstract: To study the effects of irrigation method of belt tillage with furrow planting (BTFP) on water use efficiency and yield components of corn, furrow irrigation at narrow rows (T2), wide rows (T3) and co-irrigation at narrow and wide rows in BTFP (T4), and flooded irrigation (T1) were set up. The results showed that the three irrigation methods in BTFP increased effective corn ears, grains and 100- grain weight, the yield increased by 6.23%, 7.08% and 8.62% compared with that of T1, respectively. Water use efficiency of T2, T3 and T4 increased by 133.22%, 78.67% and 23.08%. Irrigation water use efficiency of T2, T3 and T4 increased by 112.69% , 42.35% and 11.81% ; irrigation time of T2, T3 and T4 decreased by 62.55% , 53.69% and 27.15%. Therefore, furrow irrigation at narrow rows in BTFP (T2) is a high-efficient irrigation method for water-saving.
