摘  要:
采用光合生产潜力乘以温度订正函数的估算模式,对2011年山西省农作物的光温生产潜力进行了计算。结果表明,山西省大部分地区全年光温生产潜力为2.13×104~3.00×104kg/hm2,其中,6—7月份较大;实际生产力只占光温生产潜力的15%左右。山西省实际生产力提升空间很大,可通过提高农田的管理水平,采用新技术从而实现作物的进一步增产。

摘  要:
The thesis figured out the phtot-thermal productive potentiality of main crops and compared with the practial productivity of Shanxi province. we adopted photosynthetic productive potentiality multipling by temperature correction coefficient and provided theoretial basis for increasing crop's yield. The results showed that the phtot-thermal productive potentiality was 2.13×104-3.00×104kg/hm2 in most areas while the practial productivity was only 15%of the phtot-thermal productive potentiality, which was bigger from June to July. Low fertilization, poor irrigation facilities and rough management were the main reasons leading to the low of crop production.It has a great potentiality to raise the yield of the crops. If we improve management's standard and introduce new technology, the yield of crops will be likely to be greatly improved.
