Climatological Analysis of the Growth of Hybrid Rice and the Demarcation of Rice-growing Regions in Jiangsu
Abstract:In terms of climatic conditions during the growing season of hybridrice are determined the safe stage of the fully-heading and the periodsuitable for sowing in the different cropping systems. The thermal conditions in spring and autumn are found to be the leading factorsinfluencing on both the cropping systems and high, stable rice yields.It has been found that the last fall day of the spell of air temperature≥22℃ with probability of 80% is defined as the final day for a safestage of the hybrid fully-heading and the first spring day of the spellof air temperature ≥15℃ with the same probability as the starting ofthe safe seeding period for well-grown seedlings. With respect to thedifferent cropping systems in various parts of the province a detailed analysis is made concerning the use of local climatic resources. The demarcation of the rice-growing region based on the climatological data are also presented.
