Study on the Occurrence Regularity of Cold Stress and Rice Cropping System in Jiangxi Province

摘要:

以江西省81个常规气象观测站1961-2012年的数据为基础,对江西省“倒春寒”及“寒露风”的发生规律进行分析,确定江西省适宜的水稻种植制度。分析结果显示,受全球气候变暖的影响,江西省“倒春寒”灾害气候发生风险总体呈降低趋势;在年平均气温和秋季平均气温升高的背景下,“寒露风”灾害气候发生的风险并没有降低,且有提前出现的趋势。因此,在水稻种植制度上,除了选用耐寒性好的品种外,还应合理扩大“中熟-中熟”的搭配种植模式,同时应尽量避免双季杂交晚稻的直播栽培。

Abstract:

In order to ascertain the rice cropping system of Jiangxi Province, the author analyzed the occurrence regularity of late-spring coldness and cold-dew wind in this study, based on the data gathered from 81 meteorological stations from 1961 to 2012. The results indicated that the occurrence tendency of late-spring coldness was decreasing, because of global warming; although the annual average temperature and the average autumn temperature were rising, but the risk of cold-dew wind disaster did not decreased, and had an early emergence trend. Thus, the planting pattern of “mid-maturation/mid maturation”in Jiangxi Province should expanding reasonably, and also should avoid direct seeding cultivation of late season hybrid rice.

Key words: Jiangxi Province, late-spring coldness, cold-dew wind, rice, cropping system
