摘要

摘要: 为了探讨行向与行距对烟田环境和烤烟生长的效果,以云烟87为材料,采用裂区试验,研究了不同行向和行距对烟田土壤温度、土壤水分、光照等环境因素以及烤烟生长的影响。结果表明,覆膜垄体地温南北行向高于东西行向,土壤含水量低于东西行向;行间光照强度东西行向优于南北行向,而同行株间光照南北行向好于东西行向;南北行向的烤烟发育进程早,生长势好于东西行向,叶片光合速率大于东西行向。相同行向不同行距间的地温和净光合速率差异不明显,但与另外两个行距水平相比,宽窄行交替种植处理更有利于保持土壤水分;行距1.2 m处理光照最差。因此,在中纬度皖南烟区,烤烟南北行向种植优于东西行向。

Abstract: The objectives of this investigation were to study the effects of row directions and row spacing on field environment (soil temperature, soil moisture, illumination) and growth of flue-cured tobacco (cv. Yunyan 87). The experiment was a split plot design with row direction as main plot and row spacing as subplot. The results showed that the soil temperature of ridge of S-N direction was higher than that of E-W direction, but the soil moisture was lower than S-N direction. Between the different lines, the illumination of E-W direction was better than S-N direction, while among plants of same line in S-N direction was better than E-W direction. Meanwhile, tobacco in S-N direction developed earlier, grew better than E-W direction, and the net photosynthetic rate was slightly higher than E-W direction. Row spacing had no significant effect on soil temperature and net photosynthetic rate, but when row spacing was 1.1-1.4×0.5 m, it was better in keeping soil moisture. And when row spacing was 1.2 m, the illumination was poor. The study indicates that planting flue-cured tobacco by S-N direction was better than E-W direction in the middle latitude area of South Anhui.
