2010年春季(3-5月)气候呈现气温低、降水多的特点。全国平均气温为9.5℃,较常年同期略偏低,农作物发育期普遍推迟;大部地区降水偏多,西北、华北和黄淮地区农田土壤墒情良好,冬小麦后期生长发育和春播作物出苗顺利。东北地区低温、雨雪导致春耕春种进度明显推迟。3、4月份的低温霜冻天气导致设施农业、经济林果受损较重。长江中下游及以南大部地区强降水过程集中,低温阴雨寡照突出,油菜的成熟收晒和棉花等春播作物播种出苗受到影响。西南地区罕见的秋冬春连旱,导致冬小麦、油菜等小春作物和经济作物大幅减产、春播困难;4、5月西南地区降水增加,广西、贵州、云南南部以及四川攀西农区旱情陆续缓解。
The spring of 2010 (March-May) is characterized by low temperatures and heavy precipitation. The average temperature of the whole country is 9.5 ℃, slightly lower than that of the same period of last year, and the development period of crops is generally delayed. In most areas, precipitation is relatively high. Soil moisture in farmland in Northwest, North China and Huanghuai regions is good. Post-winter wheat growth and spring crop emergence are smooth. Northeast cold, rain and snow led to the spring planting progress significantly delayed. March and April frost weather led to facilities and agriculture, economic forest damage heavier. The intense precipitation process was concentrated in the middle and lower reaches of the Yangtze River and most of the south, with the emergence of low temperature rainy and oligozoosperms. The maturity of rapeseed and the planting of cotton and other spring-sown crops were affected. Rare autumn and winter spring drought in southwest China led to a sharp reduction in spring and winter crops such as winter wheat and rapeseed. Spring ramps are difficult. Rainfall in southwest China increased in April and May, easing one after another in Guangxi, Guizhou, southern Yunnan and Panxi rural areas in Sichuan.
