高梁出苗后25d内干物质积累较少，25d后积累迅速增加，50～100d达到高峰；高梁对氮磷钾养分吸收高峰在出苗25～50d，积累强度分别达氮2．12dmg／株·d、磷0．87mg／株·d和钾1．84mg／株·d，50d以后高梁对养分的吸收逐渐减少。
Sorghum accumulated less during 25 days after emergence, increased rapidly after 25 days and peaked at 50 ~ 100 days. Sorghum had the highest absorption of N, P, and K nutrients at 25 ~ 50 days after emergence, with accumulation intensities of 2.12 dmg / d · d, Phosphorus 0.87mg / plant · d and potassium 1.84mg / plant · d, sorghum absorption of nutrients after 50d gradually reduced.
