摘　　要：利用2004至2005年春小麦分期播种试验,取得春小麦在不同气象条件下的发育期、干物质积累量、产量等资料,利用统计分析方法,分析了灌溉条件下平均温度、平均最高气温、平均最低温度、日较差、相对湿度、日照、大于0℃积温、降水等气象因子对宁夏灌区春小麦的干物质积累量及产量的影响,结果表明:在春小麦的营养生长阶段,大于0℃积温与叶干重成显著负相关;在全生育期及生殖生长阶段,平均最高气温、平均最低温度与干物质积累量成负相关;日较差、日照、大于0℃积温和相对湿度与干物质积累成正相关;大于0℃积温与实际产量相关性显著,成正相关;平均温度和降水与干物质积累量和产量相关不显著。Got the accumulating amount of material , output , etc according to the spring wheat experiment from 2004 to 2005 year under different meteorological conditions, Analyzed the relation between the outputs , dry mattes accumulations and the average temperature , average maximum temperature , average minimum temperature , temperatures difference , relative humidity , sunshine , greater than 0 degrees Centigrade of accumulated , Precipitation. The result shows ： Greater than 0 degrees Centigrade of accumulated temperature and dry weight of the leaf to become and shoulder notably relevantly during the course of growing in nutrition of the spring wheat; At the whole breeding time and stage of growing of reproduction, average the highest, the minimum temperature is correlated with doing the accumulating amount of material to become and shoulder ; Than poor , sunshine , greater than Japan 0 accumulated temperature , and relative humidity correlated with doing materials to accumulate; It is remarkable to be greater than 0 degrees Centigrade of accumulated temperature and actual output dependence , become positive correlation; And cant do the accumulating amount of material and is correlated with output remarkably in average temperature.
