摘要
从根系分泌物的自毒作用、土壤化学性状恶化、土壤微生物区系改变和土壤酶活性下降等方面综述了近年来烤烟连作土壤环境中障碍因子的研究结果,并对该领域今后的研究方向提出了展望。
Research on factors hindering continuous cropping of flue-cured tobacco in soil ecosystem was reviewed with regards to autotoxieity of flue-cured tobacco roots exudates, deterioration of soil chemical characteristics, change of soil microbial riora, and decline of soil enzyme activities. Future research directions were proposed .
