【摘要】 利用桓台县气象资料和小麦产量资料,分析了2013~2014年度桓台县小麦生长发育特点,将群体变化动态、灌浆速率等指标与往年进行比较,对2013~2014年度桓台县小麦生产的有利和不利气候条件进行了综合分析。结果表明,2013~2014年度桓台县小麦播种期温湿条件适宜,小麦播种质量提高;冬季气温偏高,小麦安全越冬;春季气温回升快,小麦生育期提前,但前期干旱影响亩穗数提高和中期低温影响穗粒数提高;小麦灌浆期提前,粒重增加,但连续干热风不利于小麦灌浆。更多还原

【Abstract】 Meteorological data and wheat yield data in Huantai County were used to analyze the wheat growth and development characteristics of Huantai County from 2013 to 2014. The population dynamic variation,grain filling rate and other indexes were compared with those of the previous years. Favorable and adverse weather conditions of wheat production were comprehensively analyzed in Huantai County from 2013 to2014. Results showed that wheat sowing stage of Huantai County from 2013 to 2014 had proper temperature and humidity characteristics; the sowing quality of wheat enhanced. Temperature in winter was abnormally high,so that wheat passed winter safely. Temperature in spring returned rapidly so that wheat growth stage was ahead of time. However,drought stress at early stage affected the spike numbers; and low temperature at middle stage influenced the improvement of grains per ear. Wheat filling stage was in advance; grain weight increased,but continuous dry-hot wind was not good to wheat grouting.更多还原
