| 摘 要： | 根据新源县气象站1982—2018年冬小麦生育期、产量及同期气温、降水、日照时数资料,采用线性回归、pearson相关系数、3 a直线滑动平均等统计方法,研究了近37 a来新源县冬小麦对气候变化的响应。结果表明:近37 a来新源县冬小麦冬前生育期显著推迟,返青至乳熟期显著提前,春、夏季生育期提前主要受3月上、中旬气温影响。出苗—越冬开始期显著缩短、乳熟—成熟期显著延长,其它各生育期间隔无显著变化,全生育期缩短是由播种期显著推迟造成的。冬小麦气候产量与营养生长期的气象要素显著相关。播种期显著推迟导致冬前的热量积累不足,建议播种期提前10 d左右,利于形成壮苗。

| Abstract: | the response of winter wheat to climate change in Xinyuan County in recent 37 years was studied by using linear regression, Pearson correlation coefficient, 11 year linear moving average and other statistical methods according to the data of winter wheat growth period, yield and temperature, precipitation and sunshine in different periods of the same period from 1982 to 2018 at Xinyuan national general meteorological station. The results showed that in recent 37 years, the growth period of Winter Wheat in Xinyuan county was significantly delayed before winter, and the main growth periods from returning to green to milk ripening were significantly advanced, which was related to the significant increase of temperature in autumn, spring and summer in Xinyuan county. Affected by this, the whole growth period was significantly shortened, but there was no significant change in the interval of each growth period in the vigorous growth stage of winter wheat. Although the rising trend of temperature is obvious, it is within the suitable temperature of winter wheat growth period. Precipitation and sunshine have little effect on growth period. There is a significant positive correlation between the winter wheat climate yield and the negative accumulated temperature in the overwintering period. |
