The plant density is not obvious to the grain yieldsoil moisture use efficiency influence, but is obvious to the biological yieldsoil moisture use efficiency influence.
种植密度对籽粒产量土壤水分利用效率影响不明显,但对生物产量土壤水分利用效率影响明显。

This is because that organic matter enriched not only phosphorous in the high yieldsoil, but also increased soil phosphorous availability through decreasing absorption and fixation.
