针对玉米生产中存在的盲目施肥、肥料利用率偏低等问题,开展了施用不同肥料的田间小区试验。试验共设置不施肥(CK)、测土配方施肥(T1)、控释尿素一次性基施(T2)、有机无机肥配施(T3)等4个处理,考察了不同处理的玉米农艺性状、产量、经济效益和肥料利用率等指标。结果表明:T3处理的玉米农艺性状、产量、经济效益均最优,肥料利用率显著高于其他处理的。
In response to issues in maize production such as indiscriminate fertilization and low fertilizer utilization efficiency, a field plot experiment is conducted to investigate the effects of different fertilizer applications. Four treatments are established: no fertilization (CK), soil testing and formulated fertilization (T1), one-time basal application of controlled-release urea (T2), and combined application of organic and inorganic fertilizers (T3). Indicators such as maize agronomic traits, yield, economic benefits, and fertilizer utilization efficiency are evaluated. The results show that T3 treatment exhibits the best maize agronomic traits, yield, and economic benefits, with significantly higher fertilizer utilization efficiency compared to the other treatments.
