| Abstract: | Based on field investigation and data analysis on input and output of nitrogen and phosphorous of different farmlands in upper-reaches water resource protection zone of Huangpu River,the balance status of nitrogen and phosphorous of farmlands were studied,by using the evaluation method of nutrient surplus and deficit rate.Results indicated that the real nitrogen surplus and deficit rates of paddy field,dryland and orchard were 31.17%,49.78% and 44.33% respectively,and 30.46%,90.18% and 37.34% respectively h... |
