稻草还田方式对烤烟生长发育的影响

Effects of straw mulching on growth and development of flue-cured tobacco

试验探讨了稻草还田方式对烟田土壤水分、温度和烟叶产量、质量的影响。结果表明,用适量稻草覆盖不但能调节土层温度,具有明显的蓄水、保水作用,而且能促使烟株早生快长,延长大田生长期;尤其是对烟田前期和干旱季节的节水保水效果更明显。用适量稻草覆盖烟田,能明显提高烟叶产质量、等级结构和产值。

The test was conducted to find out the effects of straw mulching on soil moisture temperature yields and quality. The results showed that straw mulching could regulate soil temperature and keep and improve the moisture capacity with more significant effect in the early growing period and rainfall-scared days. It could also definately promote the growth of tobacco plants and expand the field growing period enhancing the growth of root system and stem of tobacco plants yields and quality grade index yield value etc.
