摘要
本文通过青藏高原20年小麦活动面温度与气温的差值同平原地区小麦活动面温度与气温差值的比较,阐述了高原积温与平原地区积温等值不等效的特征,分析了高原作物种植高度大大超过东部地区的原因,并对增加高原作物产量的途径提出了一些具体看法。
The differences between the crop canopy temperature and the an temperature for both Tibetan plateau and eastern part of China are investigated.By comparative study it is found that there exists the property of the same value of accumulated temperature but with different effects for crop-growing in the Tibitan plateau and eastern part of China.The upper limits for many crops are much higher on the plateau than in the eastern part of China.Some suggestion referring to raising the yield of crop on the plateau are presented.
