本文在研究大豆气候生态条件的基础上,整理分析了东北地区167个气象台站1959—1978年二十年≥10℃积温、生长季干燥度、年降水量和夏至可照时数资料。根据实际情况将东北地区大豆分为7个品种熟期组,相应的7个热量带,3种水分类型和3种日照长度。根抛温、光、水组合特点和大豆气候生态类型,将东北地区划分为16个大豆气候生态区。对各区的大豆气候生态条件,有利的气候资源,主要的气象灾害,适宜的品种和栽培措施,技术利用和改善途径等进行了评述。
Based on the study of soybean climatic and ecological conditions, the data of accumulated temperature of ≥10 ℃, dryness of growing season, annual precipitation and summer solstice of 167 meteorological stations in northeastern China from 1959 to 1978 were analyzed. According to the actual situation, the soybean in Northeast China was divided into 7 cultivars, 7 corresponding tropical zones, 3 water types and 3 sunshine durations. Based on the characteristics of temperature, light and water combination and the climate and climate of soybean, the northeast region is divided into 16 soybean climate ecoregions. The climate and ecological conditions of soybean in each district, favorable climatic resources, major meteorological disasters, suitable varieties and cultivation measures, technical utilization and improvement approaches were reviewed.
