Abstract:
Based on an analysis of ecoclimatic applicability for millet, the climatic yield model was established in different climatic re- gion. The key meteorological factors affecting yield were confirmed,which included≥10℃accumulated temperature, average temper- ature from Aug to Sep, precipitation in July, altitude, the rate between investment and yield and so on.An integrated index system of suitable planting division was given,and the eco-climatic planting division was divided into 5 grades.At the same time,the way to enhance utilizing efficiency of ecoclimate resources was brought forward.
Key words: millet, eco-climate, applicability, planting division
摘要:
在分析谷子气候生态适应性的基础上,建立不同气候区谷子气候产量模型。确定影响产量形成关键时段的关键气象因素是≥10℃积温、8~9月平均气温、7月降水以及海拔高度和投入产出比等适生种植区划综合指标体系,据此划分5个谷子气候生态种植区。并提出提高气候生态资源的开发利用途径。
关键词: 谷子, 气候生态, 适应性, 种植区划
