【摘要】 为了评价玉米带耕沟播模式下不同沟灌形式对水分利用效果和产量构成的影响。采用玉米带耕沟播的窄行沟灌(T2)、宽行沟灌(T3)、宽窄行共灌(T4)3种模式与生产常规大水漫灌(T1)模式进行了大田比较试验。结果表明:与大水漫灌相比,带耕沟播3个灌水方式增加了玉米有效穗数和穗粒数,提高了玉米百粒重,玉米产量提高了6.23%、7.08%和8.62%;T2,T3和T4水分利用效率分别提高了133.22%、78.67%和23.08%;灌溉水利用效率分别提高了112.69%、42.35%和11.81%;灌水周期天数缩短了62.55%、53.69%和27.15%。因此带耕沟播窄行沟灌是一种高效节水灌水模式。更多还原

【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-irrigationat narrow and wide rows in BTFP(T4), and flooded irrigation(T1) were set up. The results showed that thethree irrigation methods in BTFP increased effective corn ears, grains and 100-grain weight, the yieldincreased 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 increasedby 112.69%, 42.35% and 11.81%; irrigation time of T2, T3 and T4 decreased by 62.55%, 53.69% and27.15%. Therefore, furrow irrigation at narrow rows in BTFP(T2) is a high-efficient irrigation method for water-saving.更多还原
