<p id="C2">To clarify the difference of nutrient uptake and utilization to yield advantage between maize-soybean relay intercropping maize-peanut intercropping, we conducted a field experiment for two consecutive years. The results were obtained by comparing nitrogen (N), phosphorous (P), potassium (K) absorption efficiency in with sole cropping. showed that land equivalent ratio (LER) was 1.16-1.72, which had yield, but LER 0.89-1.13, no obvious disadvantage. In system, amount N, P, K higher than corresponding cropping 32.60%-54.22%, 27.35%-34.64, 17.74%-24.42%, respectively, N lower 21.99%-42.07%. contributions efficiencies 0.34-0.62, 0.31-0.46, 0.22-0.32, -0.11 -0.35, -0.03 -0.31, 0.22, respectively. -7.86% 31.58%, 23.09%-46.52%, 1.60%-55.48%, 7.55-26.60. P 0-0.22, 0.05-0.27, -0.11-0.32, -0.25-0.19, -0.32-0.11, -0.47-0.32, conclusion, mainly from enhanced efficiency, there due relatively less contribution advantage.
