摘要
2010年小麦全生育期农业气象条件较差,不利于产量提高。主要问题是前期潮塌和持续低温,发育期推后,后期持续高温,出现有观测记录以来的最强干热风年,小麦后期发育加快,灌浆期缩短,降低了小麦的粒重;此期日较差较大,有利于干物质积累,降低了不利因素的影响,但小麦产量仍然会受到明显影响。同时,2010年水情较好,降低了高温干热风的影响。
In 2010 the whole growing season of wheat agricultural meteorological condition is poorer,not conducive to improving yield.The main problem is The soil surface water Supersaturation on soil thawing and continuous low temperature,growth period after pushing,later period lasts high temperature,there is observational record since the strongest dry hot wind,later period of wheat growth was accelerated,grouting period shorten,reduce the grain weight of wheat;this period on the larger poor,is conducive to the accumulation of dry matter,reduce the adverse factors wheat yield,but will still be influenced.At the same time,this regimen is better,reduce the temperature of dry hot wind effect.
