摘　　要：概述我国作物养分供应现状,阐述基于生态幅的作物养分供应限理念,提出我国目前普遍存在的奢侈施肥应转变为养分临界点施肥,最大限度达到减肥增效的目标;使作物高产的科技动力进入由“质”跃至“能”的新阶段,由单一的“质”驱动进入“质-能”双驱动的新阶段,促进我国农业高质量发展。The current situation of crop nutrient supply of China is summarized,and the concept of supply nutrients from luxury to critical based on ecological amplitude is expounded.It is proposed that the luxury fertilization should be changed into the nutrient critical point fertilization,which can achieve the goal of reducing fertilization and increasing efficiency to the greatest extent;The scientific and technological power of high yield of crops shall be transformed into a new stage from“quality”to“function”,and from single“quality”driven to“quality-function”double driven,promoting the high quality development of agriculture in China.
