Abstract:
To investigate the impact of climatic variation in potential maize productivity in the plain of the West-Liao River. By using mechanism method, the dynamic changes of photosynthetic productive potential, light-temperature potential productivity and climatic potential productivity were studied. The results indicated that: their change appeared a double wave pattern curves. Photosynthetic productive potential was down overall, and mutation declined in 1981, light-temperature potential productivity emerged the rise overall, mutation dropped in 1978 and mutated increased in 1997, climatic potential Productivity was fall overall, mutation increased in 1957. The difference of light-temperature potential productivity and climatic potential Productivity increased, it evidenced the constraints of precipitation to maize production increased in recent 58 years.
