Abstract : Based on the data of daily average temperatures, precipitation and sunshine duration in rice growth period during the past 35 years (1980-2014) in Xinyang City, calculated the climate suitability of seedling stage, tillering stage, jointing-booting stage, flowering stage and filling stage after delayed sowing of japonica rice by using the climate suitability model. The results showed that, after delayed sowing, seedling stage temperatures, precipitation and sunshine duration suitability were 0.98, 0.99 and 0.63 respectively; comprehensive climate suitability is 0.85, the degree was high; tillering stage were 0.99, 0.51 and 0.54, climate suitability was 0.65, the degree was medium; jointing-booting stage were 0.99, 0.87 and 0.67, climate suitability was 0.85, the degree was higher; flowering stage were 0.60, 0.98 and 0.57, climate suitability is 0.73, the degree was higher; filling stage were 0.60, 0.98 and 0.57, climate suitability was 0.73, the degree was higher. Climate suitability of late sowing japonica rice in Xinyang area was relatively appropriate.
