摘　　要：连作障碍是农业生产中普遍存在的现象,其中植物化感作用是造成连作障碍的主要原因之一。从植物化感物质的种类、释放途径、作用机理等角度论述了植物化感作用的原理,并从多种作物上例证了植物化感作用的存在。论述了化感物质的自毒作用,并指出产生植物化感作用的化感物质的自毒作用是产生连作障碍的重要原因之一,进而提出减弱或消除自毒作用的技术措施和途径,以期在农业生产中合理利用植物化感作用、趋利避害提供参考。Obstacles of continuous cropping are an ordinary phenomenon in agriculture manufacture. And alle- lopathy of plants is one reason which caused continuous cropping obstacles. Thus, allelopathy principle of plants was reviewed from three aspects allelochemical kinds, release ways and function mechanism. Several kinds of crops were cited to prove the existence of plant allelopathy. Autointoxication of allelochemicals which is the mainly reason that caused continuous cropping obstacles were discussed. Then the strategies and sugges- tions were put forward in the end in order to weaken or remove the autointoxication of allelochemicals.
