摘要
[目的]寻找三明烟区冬季较为适宜的稻草还田方式。[方法]探讨了不同稻草还田方式对烤烟生长及产质量的影响。[结果]稻草堆沤后于起垄整畦前撒施回田处理烟株长相长势及烟叶产质量表现优于稻草溶田处理,尤其在"烂冬"天气表现更加明显,但其青枯病发率和发病程度高于稻草溶田处理。[结论]在"烂冬"天气或黏烂田可采取稻草堆沤腐烂后撒施回田的方式进行稻草还田,在中壤田冬季正常气候条件下采取100%稻草溶田,以降低青枯病发病率和发病程度。
[Objective]To find the suitable method of straw returning to soil in the winter of Sanming. [Method]The effects of different methods of straw returning to soil on growth,yield and quality of flue-cured tobacco were studied. [Result] The growth,yield and quality of fluecured tobacco of straw retting treatment were better than the straw returning directly,especially in more rain winter. But the rate and degree of bacterial wilt were higher than the straw returning directly. [Conclusion]We should take straw retting treatment and then returning it to soil in the more rain winter or sticky farmland,100% straw returning directly to soil in the normal weather for reducing the rate and degree of bacterial wilt.
