摘要
为研究氮肥增效剂与化肥配施对作物产量和氮肥利用率的影响,本研究采用田间小区试验,对不同施肥处理下水稻产量、植株氮含量和氮肥利用率等进行分析.结果表明:在同等施肥量情况下,与单施化肥相比(RF1、RF2),化肥与氮肥增效剂配施(RF1+NS、RF2+NS)可明显提高水稻产量,增产幅度分别为12.2%和 8.8%.与 RF1 和 RF2 相比,RF1+NS和 RF2+NS处理氮肥表观回收率分别显著提高了 9.26 和 6.20 百分点.综上,化肥与氮肥增效剂配施有助于减少氮肥施用量,提高水稻产量和氮肥利用效率.
Abstract
In order to study the effects of nitrogen fertilizer synergist and chemical fertilizer on crop yield and nitrogen use efficiency,field experiments were used to analyze rice yield,plant nitrogen content and nitrogen use efficiency under different fertilization treatments.The results showed that the combined application of chemical fertilizer and nitrogen fertilizer synergist(RF1+NS,RF2+NS)could significantly increase rice yield by 12.2%and 8.8%,respectively,under the same fertilizer application rate(RF1,RF2).Compared with RF1 and RF2,the apparent recoveries of nitrogen fertilizer in RF1+NS and RF2+NS treatments were significantly increased by 9.26 percentage points and 6.20 percentage points,respectively.In conclusion,the combined application of chemical fertilizer and nitrogen fertilizer synergist can help to reduce the amount of nitrogen fertilizer application and improve the yield and nitrogen use efficiency of rice.
