Abstract:

To explore the drought characteristics of rice growth periods in Guizhou province, this study analyzed various characteristics of the precipitation and water demand for different growth stages of rice in the rice planting regions of Guizhou province and the frequency distribution characteristics for the different drought levels, which is based on daily meteorological data of 31 weather stations by the Crop Water Deficit Index and combined with the collaborative kriging interpolation and trend analysis methods. The results showed that the precipitation in the rice growing periods increased in the east and decreased in the west with the cumulative precipitation values of transplanting-tillering stage>heading-ripening stage>sowing-seedling stage>jointing-booting stage, and the decreasing trend of precipitation in the sowing-seedling stages could cause the occurrence of drought. The cumulative water demand in different growth periods was the heading-ripening stage>transplanting-tillering stage>jointing-booting stage>sowing-seedling stage. The water requirement of rice in sowing-seedling periods was less than the precipitation in the same period, and the drought frequencies in the different levels were lower. The high frequency regions were observed in the Tongren area and the eastern parts of southeast Guizhou in the jointing-booting and heading-ripening stages.
