摘要
在含有效锌0.3ppm的钙质棕紫泥田上,水稻高产的最优氮、磷、锌组合为:N135～180、P_2O_590～135、ZnSO_438～52kg/ha,稻谷产量可达7605～8100kg/ha。施用氮、锌肥能促进水稻植株对锌的吸收。磷降低了植株中锰含量。
Application of Zn fertilizer increased rice yield significantly with 0.3 ppm of available Zn in a calcareous purple soil. The interactions of N—P, N—Zn, P—Zn on rice yield were all positive. The optimum combination was expressed as 135—180 Kg N, 90—135 Kg P_2O_5 and 38—52 Kg ZnSO_4 per hectare. Application of N and Zn stimulated the uptake of Zn by the rice plant. P decreased the contents of Mn in the rice plant.
