采用多点、无重复设计试验实施方案,探索了测土配方施肥对水稻穗粒结构、肥料利用率、产量等方面的影响,旨在为推广水稻测土配方施肥技术提供可靠依据。试验结果表明,采用测土配方施肥技术可增加水稻有效分蘖和每穗实粒数,优化穗粒结构、提高水稻产量,增加经济效益,且具有更强的丰产性;水稻的施肥农学效率、肥料偏生产力分别比常规施肥方法提高2.52、3.03,有效提高了肥料使用效率。
A multi-point and non-repetitive design experiment was carried out to explore the effect of soil testing and fertilizer on rice ear grain structure, fertilizer utilization rate and yield. The aim was to provide a reliable basis for popularizing rice soil testing and fertilization technology. The results showed that soil testing and fertilizer application could increase effective tillering and grain number per spike, optimize ear grain structure, increase rice yield and increase economic benefits, and have a higher yield; rice fertilizer agronomic efficiency, fertilizer Partial productivity increased by 2.52 and 3.03, respectively, than the conventional fertilization methods, which effectively increased the fertilizer use efficiency.
