不同垄作覆盖方式对烤烟根际环境及产量影响

采用大田试验研究了不同垄作和覆盖方式对烤烟根际土壤温度、水分及烤烟产量与品质的影响。结果表明,常规垄型的先覆膜后覆秸秆处理和双行结合垄在整个生育期中可有效的保持垄体土壤含水量,提高烤烟的抗旱能力以及烟草生长前期土壤的温度,促进烤烟的早生快发,提高烟叶的外观质量、内在品质和产量,从而显著提高烤烟的产值。

Effects of Different Covering Ridge on the Environment of Rhizosphere,Yield and Quality of Tobacco

A field experiment was conducted to study the effects of different methods of covering ridge on the temperature and relative water content of rhizosphere,yield and quality of tobacco plants.The results showed that both the treatment of film mulching of double-row ridge and traditional style of ridge could maintain water content of the ridge body,improve the drought-resistent ability through the whole growing stage the soil temperature at early growing stage of tobacco plants and promote growth of tobacco plants at early stage,so that it was to improve the marketing values of tobacco leaves.
