采用田间小区试验的方式,以云烟97为试验材料,研究了烟田垄体走向对烟田微生态环境的影响.结果表明,移栽45d时,各处理烟田二氧化碳浓度均以南北垄最高,而烟田光照则以东西垄最高,植株上方10 cm处、植株上部和植株下部的烟田光照,均表现为垂直垄处理最低；植株上部的温度表现为南北垄＞垂直垄＞东西垄；植株上方10 cm处的风速表现为东西垄＞南北垄＞垂直垄,植株中部的风速表现为垂直垄＞东西垄＞南北垄,而植株下部的风速则表现为东西垄＞南北垄＞垂直垄.%A field experiment was conducted to study the effects of ridge direction on flue - cured tobacco micro - ecological environment and quality of flue - cured tobacco leaves at different positions of vigorous growth period. The results indicated that the highest CO2 concentration appeared in the treatment of south - north ridge direction, but the highest light intensity occurred in the treatment of east -west ridge direction, and the lowest light intensity in plant upper 10 cm, plant top and plant bottom all was in the treatment of southeast - northwest ridge direction. The temperature in plant upper showed that south - north ridge direction > southeast - northwest ridge direction > east - west ridge direction. The wind speed in plant upper 10 cm and plant bottom displayed that east - west ridge direction > south - north ridge direction > southeast - northwest ridge direction. However, the wind speed in plant middle showed southeast - northwest ridge direction > east - west ridge direction > south - north ridge direction.
