摘要: 为了研究气象条件对水稻生产的影响,为当地水稻的种植生产提供依据,对安徽南陵2005—2014年早稻、中稻和一季晚稻、双季晚稻全生育期的主要气象因子进行分析评价,研究其对各类水稻气象产量的影响,并定量计算出各气象因子与该三类水稻气象产量的相关系数。结果发现:水稻气象产量具有明显的年际变化,早稻和双季晚稻整体呈上升趋势,中稻和一季晚稻基本持平,略有下降。对比分析和相关性显示,早稻气象产量与降水量和蒸发量相关性较大,且与降水量和蒸发量分别呈负相关和正相关;中稻和一季晚稻受温度、蒸发量和降水量影响显著,与蒸发量相关性最大,并且与降水量成正比,与温度、蒸发和日照时数成反比;双季晚稻与各气象因子的相关性较前两种水稻偏小。该研究获得了南陵不同气象因子对水稻生长的影响程度,为今后水稻种植合理避开气象灾害打下基础。

Abstract: In order to study the influence of meteorological conditions on rice production and provide reference for rice planting in Nanling, Anhui Province, the main meteorological factors in the whole growth period of early season rice, middle-season rice and late season rice, double cropping late rice from 2005 to 2014 were analyzed. Then the correlation coefficients between meteorological factors and the meteorological yield of rice were calculated. The results showed that there was obvious inter-annual variability of rice meteorological yield with an increase trend of early season rice and double cropping late rice and a slight decrease trend of middle-season rice and late season rice. Comparative analysis and correlation coefficients suggested that meteorological yield of early season rice had negative and positive correlation with precipitation and evaporation, respectively, and the correlation was strong. Meteorological yield of middle-season rice and late season rice was affected by temperature, evaporation and precipitation obviously, and evaporation had the strongest effect. Meteorological yield of middle-season rice and late season rice had positive correlation with precipitation while had negative correlation with temperature, evaporation and sunshine duration. The correlation between meteorological yield of double cropping late rice and meteorological factors was relatively small. It was concluded that different meteorological factors impacted on rice growth in Nanling, and the results would lay a foundation for avoiding the meteorological disasters in rice planting.
