我国南方作物高效施钾技术的研究进展

The research progress of potassium efficient application technique in South China

本文扼要地总结了近年来中国南方地区主要农作物高效施钾技术的研究结果,从土壤供钾水平、作物种植方式、营养元素之间的相互关系与作用、作物水分利用效率、土壤物理性状等方面阐明了平衡施用钾肥对作物生产和作物抵抗外界胁迫的促进作用。

This paper briefly summarized the main research result of potassium efficient application technique for the main crops in South China in recent years. It indicated the promoting effect of balanced application potassium fertilizer to crop production and crop resistance stress by showed the research result from soil potassium supply ability, crop planting patterns, relationship and interaction between different nutrient element, crop water use efficiency, and soil physical properties.
