Abstract: The analysis suixi many years wheat output and the corresponding ten-day period sunshine hour, the average temperature and the precipitation material indicated that the normal year light lukewarm water increase and decrease and the wheat each birth stage basically tally to the climate request, the light hot resources can satisfy the wheat growth, the precipitation feel slightly insufficient. The wheat sows seeds—minute tiller time meteorology aspect limit factor is a precipitation, survives the winter time and turns green —jointing stage limit factor is the temperature, is in the milk—mature period illumination time, the temperature, the precipitation has to the output affects greatly.Climate transitional characteristic is extremely obvious, the meteorological Disaster is many but frequent, these cause the wheat output remarkable undulation. Produces must base the local climate characteristic,seeks victory,minimizes losses, takes measures against natural disasters, reducts disasters, through optimizes the small wheat seed layout, cultivates fat way and so on soil and standardized cultivation, to safeguard wheat high and stable production.
