| Abstract: | Effects of optimized fertilization and application of microbial fertilizer on the nitrogen and phosphorus runoff losses under Phyllostachys praecox stands in a small watershed located in the source area of Taihu lake.Results showed that compared with the conventional fertilization treatment the total N concentrations of runoff water under Phyllostachys praecox stands with the treatments of optimized fertilization and microbial fertilizer were decreased by 35.3% and 39.2%,respectively,and the total N losses ... |
| Keywords: | optimized fertilization microbial fertilize N and P runoff Phyllostachy praecox stands |
