    摘要:

    连作导致花生产量和品质下降,严重影响了花生持续生产。本文结合20年花生长期定位试验研究,从土壤理化性质恶化、化感自毒作用和微生物区系失衡3个方面系统地综述了花生连作障碍的发生机理,认为花生根际微生态系统综合功能失调是造成花生连作障碍的主要原因,并分别就化感作用、根际分泌物与根际微生物的关系、根际微生物与连作障碍的关系和多因子综合考虑等角度对该领域未来的研究方向进行了展望。

    Abstract:

    Continuous cropping results in decrease of peanut production and quality which seriously affecting peanut sustainable production. Based on a long-term located experimental research of peanut for twenty years, the paper reviewed systematically the mechanisms of peanut continuous cropping from the deterioration of soil physiochemical properties, allelopathic autotoxicity and imbalance of microflora, suggested that comprehensive dysfunction of peanut rhizosphere microecosystem is the major reason of continuous cropping obstacle. The further studies are also suggested included allelopathic effect, relation between root exudates and rhizosphere microorganisms, relation between rhizosphere microorganisms and continuous cropping obstacle as well as consideration of multifactor.
