| 摘 要： | 利用1981—2000年甘肃全省71站点胡麻产量和生长期(4～10月)气象资料,用EOF、小波分析和积分 回归等统计分析方法分析胡麻产量的时空特征,以及不同气象因子对胡麻产量的影响。结果表明,胡麻产量分布 由北向南依次递减;在降水量变化一定的条件下,胡麻产量随温度的升高而降低;在温度变化一定的条件下,胡麻 产量随降水的增加而增加,适时早播可避免胡麻籽粒期高温对产量的影响。为适应气候变化,应积极试验扩大复 种面积,提高商品量。

| Abstract: | The yield variability caused by growth time and location as well as the effects of climate factors on the yield of linseed were analysed base on the data collected from 71 location of Gansu province during 1981-2000 using EOF, wavelet and regression methods. The results showed that the yield of linseed decreased gradually from north to south. Under certain amount of rainfall, the yield of linseed decreased along the increase of temperature, whereas under certain temperature, the yield of linseed increased along the increase of rainfall. Early sowing could avoid the influence of high temperature on yield at seed developing stage. In order to adapt to the climate change, the planting area should be expanded for the increase of total production. |
