Abstract

Abstract: The paper aims to study the adaptability of summer maize to climate change in Langfang Region. The authors calculated and analyzed the climate suitability degree of temperature, precipitation and sunshine at each growth stage and the whole growth period of summer maize. The results indicated that the suitability degree of temperature was the highest, then was that of sunshine, and the suitability of precipitation was the lowest in each growth stage and the whole growth period of summer maize. The temperature suitability degree increased slightly, but the sunshine suitability degree went down in the whole growth period with year. The precipitation suitability degree decreased except in 7-leaf to jointing stage and milky to mature stage, and the inter-annual fluctuation was great. The climate suitability degree was mainly influenced by precipitation, so the tendency was consistent with the precipitation suitability degree. In Langfang Region, temperature was suitable for summer maize growth, however, rainfall was the main factor which affected the yield.
