甘肃省谷子气候生态适应性分析及适生种植区划

Study on Ecoclimatic Applicability and Suitable Planting Division of Millet in Gansu Province

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。

Based on an analysis of ecoclimatic applicability for millet, the climatic yield model was established in different climatic region. The key meteorological factors affecting yield were confirmed,which included ≥10℃accumulated temperature, average temperature 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.
