摘要:

通过田间试验,研究了粳稻武育粳33的营养特性、需肥规律与肥料效应。结果表明,在生育前期,武育粳33对氮、磷的需求量大,中后期增加了对钾素的吸收;氮对其产量构成因子的影响要显著高于磷和钾;结合模拟的最佳施肥量和其经济施肥量,鄂北地区中等肥力条件下武育粳33的推荐施肥量为N 240~280 kg/hm2、P2O5 80~100 kg/hm2、K2O 90~135 kg/hm2。

Abstract:

A field experiment was conducted to study the nutrition characteristics and the fertilizer effects of japonica rice, using Wuyugeng 33 as material. The results showed that Wuyugeng 33 needs more nitrogen and phosphorus in early growth stage, but needs more potassium in the late growth stage. The effect of nitrogen on yield components was significantly higher than that of phosphorus and potassium. By model simulations, the most suitable number of fertilizer is N 240~280 kg/hm2, P2O5 80~100 kg/hm2 and K2O 90~135 kg/hm2 in north area of Hubei under medium fertility conditions.

Key words: japonica rice, Wuyugeng 33, nutrition characteristics, fertilizer effects
