摘要：

以迟熟中粳稻淮稻68和镇稻88为材料,进行超高产栽培(产量>11 thm-2),以一般高产栽培为对照,观察了氮(N)、磷(P)和钾(K)吸收和累积特点。与对照(产量>7.5 thm-2)相比,超高产栽培水稻在有效分蘖临界叶龄期前N的吸收量较低,拔节后的吸氮量较高;磷的吸收量在各生育期均高于对照,中后期尤为明显;K的吸收量在有效分蘖临界叶龄期以前,超高产稻与对照差异很小,自拔节起,前者明显高于后者。超高产栽培稻田N的输入输出基本平衡,普通高产栽培稻田表现为N盈余。在两种栽培条件下P与K均表现为表观亏缺,超高产栽培尤为严重。每生产1 000 kg稻谷所吸收的N、P和K,超高产中粳稻分别为21.6～21.9 kg、6.7～7.2 kg和24.8～25.6 kg,对照为23.8～24.3 kg、6.8～7.3 kg和27.4～29.0 kg。上述结果说明,超高产栽培中粳稻对养分吸收具有生育前期较低、中后期较高的特点,并具较高的产谷效率。对超高产栽培中粳稻养分吸收特点和养分优化管理进行了讨论。
