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。
Based on the analysis of the growing status and corresponding meteorological data of biennial alfalfa in spring, the quantitative relationship between the growth and development of alfalfa sowing and the average temperature, accumulated temperature and precipitation in Longdong Loess Plateau was discussed. The suitable planting division and climate risk zoning of alfalfa in Longdong area. Comprehensive zoning results proposed ways to develop and use of climatic resources and production of alfalfa measures for the eastern region to further adjust agricultural production structure, development of animal husbandry and provide the basis for improving the ecological environment.
