Abstract: 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.
