  • Applying different proportions of slow-release fertilizer in peach tree/soybean intercropping mode as a processing, the application of slow-release fertilizer in different proportions on sediment loss and runoff, nitrogen and phosphorus losses from peach tree/soybean intercropping mode were studied. The results showed that: in the peach/soybean intercropping model, compared with controls, application of slow-release fertilizer significantly reduced the concentration of nitrogen and phosphorus in runoff, and reduced the amount of sediment in the proportion of loss of nitrogen and phosphorus. In terms of the loss of the process, changes in the performance of the three treatments were expressed as increase in the early, decreased in the mid and late stabilized. Compared with the CK, the amount runoff and loss of treatment Ⅰ and Ⅱ were reduced by 8.15% and 23.60%, sediment loss of treatment Ⅰ and Ⅱ were reduced by 5.25% and 18.55%. So in the peach/soybean intercropping patterns, application of slow-release fertilizer can effectively control the runoff erosion, sediment erosion and loss of nitrogen and phosphorus.
