摘要
作物超高产是具有超高产潜力的品种在一定生态区域和栽培条件下诸多因素和谐互作的结果。超高产育种和栽培的目标及实现途径,因生态条件、栽培水平、作物种类以及品种类型等的不同而不同,具有相对性、区域性和阶段性。经过近20年来的探索与实践,我国作物超高产取得了较大进展。为此,详细概述了作物超高产的概念、我国三大粮食作物超高产的目标、实现途径、研究实践以及贵州省作物超高产的研究进展。
The realization of crop super-high yield is the interactive result between varieties with super-high yield and the suitable cultivation condition in the favorable ecological areas. The aim and realizing way of the variety breeding and cultivation techniques change with change of ecological condition, cultivation level, crop species and variety types, which is of relative, region and stage character. The great progress has been made in crop super-high yield for 20 years in China. The paper reviews the conception of crop super-high yield, the aim, realizing way and research situation of rice, maize and wheat in China, and the research progress in Guizhou in detail.
