2009/2010年度冬季(2009年12月-2010年2月),全国大部气温接近常年或略偏高,降水区域性差异明显。北方冬麦区光、温、水匹配基本合理,大部区域和时段降水条件较好,利于冬小麦安全越冬和后期返青生长。长江中下游地区多阴雨寡照天气,加之气温阶段性偏低,部分地区作物遭受冻害,但总体影响不大。云南、贵州等地遭受特大秋冬连旱,夏收粮油作物生长和春播生产受到严重影响。新疆北部的持续强降雪使当地牧业生产受灾严重。总体来看,北方地区农业气象条件优于南方。
In the winter of 2009/2010 (December 2009-February 2010), most of the country’s temperatures were near normal or slightly above normal, and the regional differences in precipitation were significant. The matching of light, temperature and water in northern winter wheat area was basically reasonable, and the precipitation conditions in most areas and time periods were good, which was conducive to the winter wheat overwinter and the later greening growth. Rainy weather in the middle and lower reaches of the Yangtze River, coupled with the relatively low temperature stage, suffered frost damage to crops in some areas, but the overall impact was insignificant. Yunnan, Guizhou and other places suffered heavy autumn and winter droughts, summer harvest grain crop growth and spring sowing production are seriously affected. The continued heavy snowfall in northern Xinjiang has severely affected the local livestock production. Overall, the agrometeorological conditions in the north are better than those in the south.
