农业气候相似距研究在引种中的应用

Application of Agroclimatic Similar Distance in Variety Introduction

本文采用相似距表示农业气候相似程度的新方法,并综合考虑湿润指数等指标,分析了中国与世界的农业气候相似,应用其成果从引种角度研究小麦、玉米和马铃薯等作物的优良品种推广适种范围,为开发旱区农业提供科学依据。

Using similar distance, a new method to indicate agroclimatic similarity,the similarity between China's agroclimate and the world's with consideringmoist index comprehensively. With the results, a research about the goodvarieties of Wheat, corn, potato etc. is done from the viewpoint of introdu-cing a fine variety. It trys to extend the growing areas of these crops andprovide scientific basis for developing agriculture in dry areas.
