| 摘 要： | 以陇东黄土高原主要农作物冬小麦、玉米为研究对象,提出了作物生长势的基本概念,同时分析了冬小麦、玉米各发育期生长势的影响因素,最后以生长势为量化指标,建立了陇东地区冬小麦、玉米不同发育时段生长状况评定指标体系。该体系可使农作物生长状况评定由定性向定量,由多要素向单要素转化,不但剔除了评定的不确定因素和模糊因素以及主观误差,而且使评定方法更加简便、科学。 |
| 关 键 词： | 农作物 生长状况 评定体系 陇东黄土高原 |

| Abstract: | By using winter wheat and maize in the loess plateau of eastern Gansu as investigating objects,this article brings forward the basic conception of growth potential,and proposes its impersonal definition.Furthermore,it analyzes the influential factors of growth status of the crops.Finally,the assessment index system of crop growth status is established for different periods of winter wheat and maize in eastern Gansu,which makes the crop growth assessment more quantified,simplified,convenient and accurate. |
| Keywords: | crop growth status assessment system |
