烤烟和作物轮间作提高烟叶品质的研究现状

烤烟是我国重要的经济作物，但栽培过程中存在连作障碍。烟田连作导致病害增加，影响烟叶和轮间作作物的品质，进一步影响农田产出，另一方面，连作障碍导致烤烟种植土地匮乏。生产实践发现通过与其他作物轮间作可以改善烤烟连作障碍。本文从作物-土壤-微生物组成的根际微生态系统的视角，综述了烤烟与不同作物轮间作的现状以及轮间作后的土壤生物学性状变化，分析了不同轮间作模式下土壤理化性质和根际微生物群落的变化，特别是烤烟产量和烟叶内在品质的变化，对于烤烟与作物的轮间作机制进行了总结和展望，为烤烟轮间作种植模式提供了科学依据。

Research progress on rotation intercropping of flue-cured tobacco and crops to improve tobacco quality

Tobacco is an important economic crop in China, but there is a disorder in the cultivation process. Continuous cropping of tobacco field leads to increasing diseases, and then affects the quality of tobacco leaf and crop rotation, and further affects the field output. On the other hand, continuous cropping obstacles lead to the lack of land for flue-cured tobacco cultivation. From the perspective of the rhizosphere microecosystem of crop-soil-microbial composition, this paper reviewed the current progress of cropping between flue-cured tobacco and different crop rotation and the changes of soil biological characteristics after rotation cropping, and analyzed the changes of soil physical and chemical properties and rhizosphere microbial communities under different rotation cropping modes, especially the changes of flue-cured tobacco yield and tobacco leaf intrinsic quality. This paper summarized and prospected the rotating cropping mechanism of flue-cured tobacco and crops, and provided scientific basis for the rotating cropping model of flue-cured tobacco.
