Abstract

Abstract: Based on the temperature data of two national meteorological observation stations in Suizhou city from 1957 to 2017, the variation of the occurrence probability of high temperature heat damage and low temperature cold damage over time in the heading and flowering stage of middle rice growing season was simulated by function fitting. And the suitable time period of heading and flowering was determined and its variation rule was analyzed. The results showed that the suitable period presented a increasing trend under the background of climate change in Suizhou city, the average increase was about 2 days every 10 years.

Key words: climate change, mid-season rice, heading and flowering, suitable period, Suizhou city
