Discussion and Suggestions on Technical Models for Fertilizer Reduction and Efficiency Increase
Chemical fertilizers play a crucial role in supporting national food production.However,the re-lentless pursuit of high yields in agriculture has resulted in the overuse of chemical fertilizers,leading to neg-ative consequences such as compromised agricultural product safety,wastage of resources,and environmental pollution.This undermines the goal of establishing an agricultural resource-saving society.The international community has reached a consensus on the necessity to decrease chemical fertilizer usage while enhancing efficiency.Currently,our country is advancing high-quality and eco-friendly agricultural practices through the technical approach of'refining,adjusting,modifying,and replacing'chemical fertilizers to optimize quantity and efficiency.This paper conducts a comprehensive evaluation of the progress and impact of our country's efforts to reduce chemical fertilizers and improve efficiency.It focuses on key aspects and applica-tions of modern fertilization technologies,including soil testing and formula fertilization,integrated water and fertilizer management,mechanical deep fertilization,and the substitution of chemical fertilizers with organic alternatives.On this basis,according to the needs of sustainable agricultural development,this study analyzed the problems existing in China's fertilizer reduction and efficiency improvement technology,and put forward specific suggestions for comprehensively promoting fertilizer reduction and efficiency improvement in the new stage,in order to provide reference for the construction of long-term fertilizer reduction and efficiency im-provement mechanism and regulation system.
