The grass-bean hybrid system in alpine regions was an important method to increase the root and nutrients of grasses, however, there no clear conclusion from research on whether nitrogen——phosphorus fertiliser additions had enhancement effect hybrids.Through establishment artificial mix region at 4,270 meters above sea level, we examined effects exogenous fertilizer forage roots annual grass-legume using (fertilizer application: A 1~4 vs. ratio B 1~5 ).The results illustrate that: addition nitrogen phosphorus did not significantly mixtures compared fertiliser, which appeared be more favourable; increased length projection area forage, also nutrient content soil.The CP, TN, TC, TP contents as well soil gradually fraction legume under various mixing ratios. However, percentage legumes increased, morphology trended downward, mixed treatments outperformed monoculture control.The study’s findings were follows: In test grass bean sowing areas, can surface projected system, while have significant improvement nutrients. is benefit terms improving forage’s content. This could offer direction for choosing fertilizers fertility grasslands that are combined with beans.
