河西走廊胡麻生育气候条件分析及适生种植区划

Analysis of Climate Conditions on Growth and Development of Oil Flax and Regional Assignment of Its Planting in the Regions of Hexi Corridor

分析研究得出影响该地区胡麻生育状况及产量形成的关键气象因子是 5～ 6月各旬的平均气温和 7月下旬～ 8月下旬的旬平均气温 ;其次为降水 ,光照的影响最小。关键期是胡麻苗期和蒴果形成阶段。并以此为依据进行了河西地区胡麻生态气候适生种植分区 ,提出了合理利用气候资源的途径。

According to the growth status of oil flax and its adaptability to ecological climate conditions, the key meteorological factors in the regions of Hexi Corridor were analyzed by using integral regress analyzing method. The mean temperature of every ten days during May and June, and the mean temperature of ten days during last ten days of July and last ten days of August are the most influent factors for the growth and yield forming of oil flax, followed by precipitation and solar radiation. The key periods are seedling and fruit-formation period. On the basis of mentioned results, the regional assignment of ecological climate on oil flax planting in the regions of Hexi Corridor was worked out. The reasonable utilization of climate resources was discussed.
