摘要
综述了连作对植物形态、生理、品质和产量的影响,并从土壤病虫害、土壤养分、土壤理化性质、土壤自毒物质、土壤酶活性和土壤微生物群落的变化6个方面阐述了连作障碍形成的原因,指出了植物-土壤微生物-土壤酶-土壤养分4者之间相互影响的复杂性,并对今后植物连作障碍机理研究的重点进行了展望。
The influences of continuous cropping on the morphology, physiology, quality and yield of plants were summa- rized; and the formation mechanism of continuous cropping obstacle was analyzed from six different aspects, including changes of pests, nutrition content, physicochemical properties, autotoxin substances, enzymatic activities and microbial com- munities of the soil. The complexity of interaction among plants, soil microbes, soil enzymes and soil nutrients was pointed out to provide prospects for future study on the mechanism of continuous cropping obstacle.
