摘要: 根据对春播两年生紫花苜蓿生长状况和相应气象观测资料的分析,探讨了陇东黄土高原地区春播紫花苜蓿的生长发育与平均气温、积温及降水量等生态气候条件的定量关系,据此得出陇东地区紫花苜蓿的适生种植区划和气候风险区划。综合区划结果提出开发利用气候资源的途径和生产紫花苜蓿的对策,为陇东地区进一步调整农业生产结构,发展畜牧业生产和改善生态环境提供依据。

Abstract: According to analysis of growth status and the observed climate data of alfalfa(Medicago sativa) sowed in the spring on the Loess Plateau of the East Gansu Province,the quantitative analysis of growth and development of alfalfa with the average temperature,the accumulated temperature and the precipitation was made.The divisions for growing and climate risk of alfalfa were made.The results provided the scientific base for the adjustment of agriculture and promotion of livestock development.
