Abstract:

为探索玉米化肥减量增效施肥技术，2021年承担了隆阳区玉米化肥减量增效田间肥料效应试验，研究不同施肥方式对玉米生长、产量及产量构成因素的影响。结果表明，玉米使用常规施肥量减10% (N 186.3 kg/hm²、P₂O₅ 64.8 kg/hm²、K₂O 90 kg/hm²)加高效有机肥3000 kg/hm²、40%缓控释肥(N:P₂O₅:K₂O = 24:6:10)减10% 540 kg/hm²，与推荐施肥相比，差异不显著，但是，仍然获得较高的产量。这2种施肥方式可以在玉米生产上推广应用。
In order to explore the technology of reducing and increasing fertilizer application in maize, it undertook the field fertilizer effect experiment of maize chemical fertilizer reduction and efficiency increase in Longyang District to study the effects of different fertilization methods on maize growth, yield and yield components in 2021. The results showed that compared with the recommend eder-tilization, the conventional fertilization amount decreased by 10% (N 186.3 kg/hm², P₂O₅ 64.8 kg/hm², K₂O 90 kg/hm²) plus high-efficiency organic fertilizer 3000 kg/hm² and 40% slow-release and controlled-release fertilizer (N:P₂O₅:K₂O = 24:6:10) decreased by 10% 540 kg/hm², there is no significant difference but still achieved higher yield. These two fertilization methods can be popularized and applied in maize production.
