硅肥对超级早稻氮利用效率的影响
Effect of Silicon Fertilizer on Nitrogen Utilization Efficiency of Super Early Rice
摘要
Abstract
Effects of silicon fertilizer on nitrogen utilization efficiency and nitrogen accumulation of super early rice were investigated in this study with Zhuliangyou819 (Lodging sensitive variety) and Luliangyou996 (Lodging resistant variety) as materials. The main results were showed : under the condition of both nitrogen application and without nitrogen application, nitrogen accumulation, nitrogen use efficiency, nitrogen uptake efficiency, nitrogen fertilizer efficiency and nitrogen utilization efficiency of super early rice were improved by silicon application, while nitrogen physiological efficiency was slightly decreased. The effects of silicon fertilizer application on nitrogen content in leaves, stems and panicles of two super early rice varieties were relevant with nitrogen application rate. Under the conditions of 150 kg/hm2 of nitrogen application, effects of silicon application on nitrogen utilization efficiency and nitrogen accumulation were most significant in both varieties. Therefore, combined application of nitrogen and silicon was advantageous to increase fertilizer use efficiency in super early rice production.关键词
