In order to understand the effect of different interplantation models on the soil and water losses of young tea oil plantations(Camellia oleifera),the soil and water losses of pure tea oil plantation;tea oil + big green bean(Phaseolus aureua);tea oil + peanut(Arachis hypogaea)were investigated for a whole year in Xinyu,located in the central Jiangxi *** results showed that the surfaced runoff ranged from 102.03～157.29 t·hm-2a-1 with the average of 136.16 t ·*** less value was observed in the inter-cropped plantation with peanut,and the runoff values from the pure plantation was very similar to that from the inter-cropped plantation with big green bean,and both were greater by 46.21% and 54.17%,respectively,compared with the inter-cropped stand with *** soil erosion was 139.9～341.3 t·km-2a-1 with the average of 239.9 t·km-2a-1,and the values from the inter-cropped plantations with big green bean and peanut increased by 143.96% and 70.40%,respectively,compared with the pure oil *** soil erosion in the 3 type stands was all *** nutrient loss ranked from great to small value as the following:Ca 4.645 3 kg·hm-2a-1,K 1.402 6 kg·hm-2a-1,Mg 0.265 1 kg·hm-2a-1,P 0.042 6 kg·hm-2a-1,N 0.039 1 kg·*** loss in the first half year was significantly greater than that in the second half year,regardless inter-cropped or *** peak value appeared between March and *** losses of N,P,and K in the inter-cropped plantation with the big green bean were less than those in the inter-cropped stand with *** loss of K in the inter-cropped stand with peanut was almost the same as the pure plantation,however,the losses of N and P in the inter-cropped stand with peanut were less by 50 percent than that in the pure plantation.
