摘要

By the field experiment,we research the rice nutrient use efficiency. And the results show that the formulated fertilization can improve the fertilizer nutrient use rate,and N,P2O5,and K2O are improved by 121%,38%,and 64%,respectively; soil nitrogen level and application rate of nitrogen are the key factors affecting the rice yield.
