| 摘要: |
| 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. |

| Abstract: |
| Crop yield analysis is essential and important for crop breeding and cultivation.This paper reviewed current methods for crop yield analysis,including yield component analysis,growth and matter production analysis,and source-sink analysis,and pointed out their disadvantages and problems in applications according to the current crop production developing situation.Meanwhile,to satisfy the requirement of high yield and greater efficiency under resource constraints,a new model based on the efficiency of resour... |
