| 摘 要： | 通过田间小区试验,研究了不同垄体走向对打顶期烤烟不同部位微生态环境的影响。结果表明:烟株群体内温度和CO2浓度均以东南西北垄处理最高;相对湿度以东南西北垄最低;风速表现为南北垄>东南西北垄>东西垄;光照、垄沟和垄上5 cm和20 cm土层温度在3个垄体走向处理间差异不大;不同垄体走向下温度随烟株高度的增加而降低,相对湿度、CO2浓度、风速和光照各部位表现不一致;垄沟和垄上5 cm和20 cm土层温度峰值出现时间各异。 |
| 关 键 词： | 垄体走向 烤烟 微生态环境 打顶期 |

| Abstract: | A field experiment was conducted to study the effects of ridge-direction on the micro-ecological environment in the different positions of flue-cured tobacco plant in topping period.The results indicated that the temperature and CO2 concentration in tobacco plant colony of southeast-northwest ridge were the highest,but the relative humidity in tobacco plant colony of this direction of ridge was the lowest.The change trend of wind speed indicated that: south-north ridge > southeast-northwest ridge > east-west ridge.The light intensity,and 5 cm and 20 cm deep soil temperature of both the ridge and ridge-ditch had little differences among these three ridge-direction treatments.The temperature in tobacco plant colony of different ridge-direction treatments decreased with the increase in tobacco plant height,and the relative humidity,CO2 concentration,wind speed and light intensity had different performances in different positions of tobacco plant,and the peak of 5 cm and 20 cm deep soil temperature of both the ridge and ridge-ditch appeared at different time. |
