不同秸秆覆盖处理对烟田土壤速效养分含量及产质量的影响

Effects of Different Mulching Treatment upon Available Nutrient,Yields and Quality of Tobacco Field Soil

[目的]为了筛选有利于提高土壤营养且改善烟叶成分的秸秆覆盖方式。[方法]研究了不同秸秆(春冬小麦)覆盖处理对烟田土壤速效养分及产质量的影响。[结果]经过秸秆覆盖处理的小区土壤速效养分的含量及产质量明显高于对照;以全秸秆覆盖、团棵期倒垄培土处理的效果最好。[结论]在烟叶实际生产中,建议采取全秸秆覆盖,并且在团棵期倒垄培土。

[ Objective ] The research aimed to screen the available straw mulching mode beneficial to the improvement of soil nutrient and the optimization of tobacco components. [ Method] The influence of different covering processing of straws （spring-and-winter wheat） on available nutrients as well as yield and quality of tobacco field soil were studied. [ Result] Available nutrients of the soil from the section which was ap- plied straws covering processing were higher than those of controlled processing as well as yield and quality. Above all, the best result could be acquired by over-all straw covering and the rosette stage inverted ridge planting. [ Conclusion] Whole straw should be mulched in the rosette stage and inverted the ridge earth during actual tobacco production.
