- Abstract:
- Through 21 runoff plots in the sloping cultivated lands including a control treatment, six combination patterns of hedgerows of different treatments, the effects of hedgerows of species configuration on the interception of nutrition elements in the sloping cultivated lands were discussed. The results showed that the hedgerows of Tephrosia purpurea L. Pers. and Medicago sativa L., have the significant effects on interception of nutrition elements, of which relative interception of total nitrogen, phosphorus, potassium are 181.82 g/hm2, 84.81 g/hm2 and 11.37 g/hm2 and relative interception rates are 79.08%, 90.31% and 83.84%, respectively, which is the best combination pattern than others in terms of effects of interception of nutrition elements in the sloping cultivated lands. However, the hedgerow of Tephrosia purpurea L. Pers. and Hemerocallis citrina Baroni, total relative interception of nitrogen is 117.30 g/hm2 and relative interception rate is 51.02%, which is worse than others with regard to effect of interception of nitrogen element, and the hedgerow of Tephrosia purpurea L. Pers. and Vetiveria zizanioides L., relative interception of total phosphorus, potassium of is 55.43 g/hm2 and 6.62 g/hm2, and relative interception rates are 59.02% and 48.86%, which is worse than others in terms of effects of interception of phosphorus, potassium elements. The results also show that all hedgerows of species configuration are obvious on the interception of nutrition elements in the sloping cultivated lands, but the combination of Tephrosia purpurea L. Pers. and Medicago sativa L. is the best combination pattern.
