2000-2001年在湖南省宁乡县、湘潭县、华容县进行了不同肥料配比和施用方法的试验,研究了施肥对优质早稻(中鉴100)和优质晚稻(中香一号)的产量和稻米品质的影响及优质栽培的生理指标.结果表明,按施氮量为135 kg/hm2配比的复合肥一次性全层施用,能满足优质水稻前中后期的养分需要,改善米质和增加产量.施肥对稻米品质的影响年际间存在差异,但对产量及产量构成的影响年际间差异不大,以配比为N(20.0%)∶P2O5(7.6%)∶K2O(15.3%)∶S(3.9%)∶Zn(0.1%)∶Mg(0.6%)的复合肥在移栽前一次性全层施用, 产量较高(6.5-6.7 t/hm2),米质较好,抗倒性增强.

The experiment of different formula fertilizer and its application method was conducted in three counties (Ningxiang, Xiangtan and Huarong) of Hunan province in 2000 and 2001.The effects of the fertili zation on the grain yield and quality and the physiology index of high quality cultivation in early rice (Zhengjing 100) and late rice (Zhengxiang 1) were studied. The results showed that the compound fertilizer with 135 kg N/hm and one time application can meet the requirements of high quality rice for nutrients and enhance the rice quality and ...
