作物产量分析对于指导作物育种和栽培实践具有重要意义。对现行作物产量分析方法(产量构成因素分析、生长与物质生产分析、源库分析)进行了评述,结合当今作物生产发展形势指出了这些方法在应用中存在的问题。同时,从资源限制下高产高效的要求出发,提出了基于资源利用效率的作物产量分析模式,并对其应用进行了探讨。
Crop yield analysis is of great importance to guide the practice of crop breeding and cultivation. The present crop yield analysis methods (yield component analysis, growth and material production analysis, source and sink analysis) are reviewed. Combining with the current situation of crop production, the problems in the application of these methods are pointed out. At the same time, based on the requirements of high yield and high efficiency under resource limitation, a crop yield analysis model based on resource utilization efficiency was proposed and its application was discussed.
