摘要
为探索承德市玉米田农药化肥减施效果,实现减量增效的目标,以常规生产模式为对照,开展玉米“一替双减”技术模式试验。结果表明,“一替双减”技术模式较常规模式肥料氮用量减少2.2 kg/667 m^(2),农药用量减少70 mL/667 m^(2),生产总成本减少130.42元/667 m^(2),杂草防治效果增加2.47%~10.90%,增产9.17%,净收益增加323.78元/667 m^(2),肥料利用率增加36.74%。“一替双减”技术模式能实现玉米田化肥农药减量增效,可代替传统模式在玉米生产中大面积示范推广。
To explore the effectiveness of reducing fertilizer and pesticide use in corn fields in Chengde and to achieve the dual objectives of minimizing inputs while enhancing efficiency,a field experiment was conducted to assess the"one substitution,two reductions"("one-for-two reduction")technology model,using the conventional production system as a control.The results demonstrated that,compared to the conventional model,the"one-for-two reduction"approach reduced nitrogen fertilizer application by 2.2 kg per 667 m^(2),pesticide use by 70 mL per 667m^(2),and total production costs by 130.42 yuan per 667m^(2).This model improved weed control efficacy by 2.47% to 10.90%,increased yield by 9.17%,enhanced net income by 323.78 yuan per 667m^(2),and boosted fertilizer utilization efficiency by 36.74%.These findings indicate that the"one-for-two reduction"technology is an effective strategy for reducing fertilizer and pesticide use while maintaining or improving productivity.Moreover,it presents a viable alternative to traditional practices for large-scale application in corn production.
