| Abstract: |
| 【Objective】 The aim was to make a rational use of natural resources to improve the wheat production in Henan province.【Method】 Based on the climatic materials in 35 years provided by Henan Bureau of Meteorology and AZE proposed by FAO,the potential of photo-thermal production and the wheat production in Henan province were investigated.【Result】 The investigation demonstrated that the theoretical value of photo-thermal potential for wheat production in Henan was about 7 655.8-14 792.5 kg/hm2;the average potential development capacity was 46.7%. 【Conclusion】 It indicated that the wheat production potential differed significantly with the climatic changes and the divergence between potential for wheat production and the actual production level was also quite great in different parts of the province.Therefore,the development potential for wheat production in Henan is promising. |
