摘要
为验证缓控释肥在玉米上的应用效果,采用田间小区试验探讨其对玉米植株生育性状、产量、作物肥料农学表观利用率的影响。结果表明:缓控释肥能明显改善玉米生育性状;比当地常规施肥增产36.2 kg/667m^2,增产率4.9%,差异达到极显著水平;农学表观利用率增加2.7。
In order to verify the application effect of controlled release fertilizer used on maize, this paper discussed the effect on breeding traits, yield and crop fertilizer agronomy apparent utilization by using field plot experiment. The results showed that： controlled release fertilizer can obviously improve maize breeding traits; increase output to 36.2 kg/667 m^2 compared to local regular fertilizing, increasing rate is 4.9% with difference reaching significance level; agronomy apparent utilization increases 2.7.
