农业气候资源配置对天水山旱地玉米的影响

Influence of Agricultural Climate Resources Allocation on Hill Dryland Maize of in Tianshui of Gansu Province

通过对1985-2004年山旱地玉米产量与玉米不同生育时段光、温、水等气象条件统计分析,利用逐步回归方法得出了影响山旱地玉米产量形成的主要气象因子;按照光温、温水、光水、光温水要素进行积商组合,同气候产量要素系数进行相关分析,得到了不同农业气候资源要素组合配置的适宜范围,研究结果对农业生产具有指导意义。

Based on the yield and meteorological data, such as sunlight, temperature and precipitation during 1985-2004 in different growing periods of hill dryland maize in Tianshui, the main meteorological factors which influenced the yield of hill dryland were analyzed, by stepwise regression method. The relationship between sunlight-temperature, temperature-precipitation, sunlight-precipitation and sunlight-temperature-precipitation with the main meteorological factors coefficients were analyzed as well. The suitable range of different agricultural climate resources allocation was identified. The results are of significance for the agricultural production.
