The unfavorable weather conditions were embodied in the following aspects: flowering-less rainfall in milk stage, could not add wheat water requirement, but little impact; Flowering- mature, small diurnal range, is not conducive to accumulation of photosynthetic wheat grouting period. Overall, meteorological conditions in the whole stages of wheat its growth was very good in 2014, because the wheat dry-hot wind damage was small, and no major meteorological disasters, so the yield increased more over in 2013.
