The effects of new nitro-compound fertilizer on yield, benefit and fertilizer-saving of rice were studied by field experiment. The results showed that, the yield of new nitro-compound fertilizer treatment was increased by 0.38% compared with the conventional fertilization treatment, decreased by 2.06% compared with farmer accustomed fertilization treatment, but the difference was not signifi-cant. The fertilizer-saving effect of nitro-compound fertilizer treatment was obviously compared with the other treatments, the fertilizer amount was decreased by 17.2%~24.3%.%通过田间试验,研究了新型硝基双效肥对水稻产量、效益和节肥情况的影响.结果表明,在等养分条件下,硝基双效肥相比常规施肥处理增产0.38%,但与农民习惯施肥处理相比减产2.06%.方差分析结果表明,各处理产量差异均未达到显著水平.施用硝基双效肥处理与农民习惯施肥处理和常规肥料处理效益基本相当,但减肥效果比较明显,小区试验减少率为17.2%,示范对比减少率为24.3%.
