摘　　要：For a long time, milk vetch has been an important green manure crop to provide fertilizer source for rice in rice planting areas, especially in nitrogen fixation and selenium enrichment. In order to better realize the important value of milk vetch as a green manure crop, further optimize the planting strategy of green manure crops and improve the utilization efficiency. It is necessary to explore the specific effects of milk vetch on selenium content and yield of rice. This experiment is based on this theme. The final results show that the absorption capacity of selenium by milk vetch in paddy field is significantly stronger than that of rice. In order to ensure the selenium content of rice, trace selenium element (exogenous) can be applied to rice, and the yield of rice can also be effectively improved.
