摘要
运用多种数理统计方法,对黑龙江省红兴隆地区4年甜菜含糖率与平行观测的气象资料进行分析。结果表明:(1)7月上旬的平均气温及6月下旬、9月上旬的日照时数与含糖率呈极显著正相关;5月下旬平均气温、7月中及8月上旬降雨量与含糖率呈极显著负相关。(2)平均气温和日照时数在9月中旬对含糖率的影响最大,旬平均气温每升高1℃可使含糖率增加0.65%,日照时数每增加1h,含糖率可增加0.61%,旬降雨量在8月上旬对含糖率的负效应最大,每增加1mm含糖率降低0.6%。(3)影响含糖率的综合气候关键期为9月中旬,主导气象因子是日照时数。
By using mathematical statistics method,the relationship between beet sugar content and meteorological factors observed for 4 years on Hongxinglong area in Heilongjiang province was analyzed.The result shows：（1）there is a significantly positive correlation between the meteorologic factors（average air temperature on early July and the sunshine hour on late June and early September） and sugar content of sugarbeet;there is significantly negative correlation between the meteorologic factors（average air temperature on late May and the rainfall on mid June and early August） and sugar content of sugarbeet.（2）the sugar content on mid September is influenced by the average temperature and sunshine hours.the average temperature rises 1℃ in every 10 days,and the sugar content increases by 0.65%;the sunshine hour rises 1h,and the sugar content increases by 0.61%;the amount of rainfall on early August immensely negatively effect on sugar content,increases 1mm meanwhile the sugar content decreases by 0.6%.（3）the key period of integrated climate factors impacting on sugar content of sugarbeet is in mid September,the dominant weather factor is the number of the sunshine hours.
