【摘要】 为了提高气候资源利用率，提升早稻产量和品质，利用赣南17个气象站1981—2021年（每年的1—4月）的气象资料，根据早稻早播所需的气象条件，分析了赣南早春气候变化特征及其早稻早播的气候可行性。结果表明：赣南早春平均气温上升趋势明显，并在2001年出现了明显增温的突变；稳定通过8、10、15℃的初日均明显提前；早春降水量变化较大，整体呈显著减少的趋势；早春日照时数则呈明显增多的趋势。因此赣南实施早稻早播的气候条件可行，且早稻早播时间应安排在3月中上旬之后。更多还原

【Abstract】 In order to improve the utilization rate of climate resources and the yield and quality of early rice, the climate change characteristics of early spring and the climatic feasibility of early sowing early rice in southern Jiangxi were analyzed by the meteorological data of 17 stations from January to April between 1981 and 2021. The results show that the average temperature of early spring in southern Jiangxi has an obvious rising trend, and the abrupt change of temperature increase occurred in 2001. The first day of steady passage of 8, 10 and 15 ℃ is obviously advanced. The early spring precipitation changed greatly, and the overall trend decreased significantly. The Sunshine in early spring showed an obvious increasing trend.Therefore, the climate conditions of early rice sowing in southern Jiangxi are feasible, and the time of early rice sowing should be arranged after the first ten days of March.更多还原
