Abstract: The negative effect of continuous cropping on growth and development of oil crops (peanut, soybean, sesame) was large. Under continuous cropping condition, the plant became shorter, dry matter accumulation decreased, senescence was accelerated, diseases and pests of plant increased, and the yield declined rapidly. Based on current research achievements on continuous cropping obstacles of oils crop home and abroad, It was viewed that there were four factors that can result in continuous cropping obstacles, which were lack of soil and plant nutrients, microbial flora imbalance, some soil enzymes activities decreased, and auto toxicity increased. This paper summarizes four restoration methods for continuous cropping obstacles by far, including that breeding continuous cropping tolerant varieties, developing special continuous cropping resistant fertilizer, improving farming ways, as well as biologics and soil disinfectants. Based on this, it was hoped to provide theoretical reference for ecological restoration measures on continuous cropping obstacles of oil crops.
