摘要
2010年早稻生产时期,受4月持续低温、5月长期阴雨寡照等特殊气候的影响,湖南省早稻部分品种(系、组合)减产且生育期延长。不同的品种(系、组合)受影响程度不一样。对13个品种(系、组合)2009和2010两年的试验数据进行分析,探讨了2010年特殊气候对湖南早稻品种(系、组合)的产量、生育期、主要经济性状等的影响。
At production period of early rice in 2010,part of varieties(lines,combinations) of rice had yield reduction and growth period extended for special climates,such as continuing low temperature in April and long-term rainy and cloudy weather in May.The influencing level of different varieties(combinations) was different.To analyze the experimental data of 13 varieties(lines,combinations) in 2009 and 2010,the influences of special climate in 2010 on yield,growth period and main economic characters of early rice varieties(lines,combinations) in Hunan were discussed.
