行向与行距对烟田水、温和光照条件及烤烟生长的影响
Effects of Row Directions and Row Spacing on Soil Temperature, Soil Moisture, Illumination and Growth of Flue-cured Tobacco
摘要
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.关键词
