Abstract: Studies on effect of continuous cropping on peanut growth and development and different agricultural methods on relief of continuous cropping obstacles were carried out under field and pot trials. Results showed: (1) Effect of continuous cropping on peanut presented through the whole peanut growth period and became more serious as plant growth，so the relief methods should be adopted as early as possible. (2) Continuous cropping significantly aggravated the foliar diseases and made it heavier with the continuous cropping years increased. (3) Adaptability among peanut types was obvious to continuous cropping. Virginia type had good adaptability and following was Intermediate type, the last was Spanish type. (4) Among the four single adopted agricultural methods to relief the continuous cropping obstacles, organic manure had the best effect which made the yield increased by 13.3%, and followed by order were strengthening the control of foliar diseases, adoption of microbial bacteria and deep plough, which increased the yield by 7.8%, 6.7% and 4.8% respectively than normal techniques. The continuous cropped peanut yield under integrated method composed by the four single methods listed above was 24.3%, higher than that under normal techniques but lower than rotated peanut yield with the same integrated method, which showed that the integrated method has still certain potential to be improved.
