Response Analysis of Main Crop to Accumulated Temperature Change in Kaifeng City
摘要
Abstract
With mathematical statistics and fuzzy mathematics method for analysis of climate warming trend of main crop growth period in Kaifeng City,the relationship between accumulated temperature and main crop yield, database was created,with the support of Excel software, the yield of wheat,corn, cotton and accumulated temperature were separated into social yield and climate amount using two order polynomial. The results showed that the trend of accumulated temperature and yield of main crop growth period was rised in Kaifeng City,the benifit of climate warming on main crop yield in Kaifeng City was more than fraud. In wheat growth period ,the rise of extreme lowest air temperature was conducive to the growth of winter wheat, extreme maximum temperature drop of cotton, corn growth period was helpful for cotton, corn yield increases. Knowing the climate change and taking effective measures actively could reduce the loss caused by meteorological disasters and improve the main crop yield in Kaifeng City.关键词
