Result showed that HPE maize performed a higher N and K absorption efficiency in low P regiment, its N, K absorption and dry matter accumulation were less affected by low P supply.

结果表明，磷高效利用型玉米 氮钾素吸收和干物质积累受低磷处理的影响较 小，表现出对 氮、钾的高效吸收。

A solution culture experiment was conducted to study the dynamics of dry matter accumulation and n, p, K absorption by flue-cured tobacco under different boron concentration.

采用溶液培养方法，研究了不同硼浓度下烤烟干物质积累动态和养分吸收动态变化特点。

There was a close relationship between the nutrient uptake and distribution of N, P, K and the accumulation and distribution of dry matter.

棉株对养分的吸收分配中心与干物质积累分配中心一致。
