在邵东县采用分期播种方法研究播期与气象条件对花生品种湘花2008生长发育和产量的影响。结果表明：不同播期花生经历不同的气象条件进而影响花生生长发育和产量，适宜播期为4月上旬；影响发育进度快慢的气象要素依次为总积温、气温、降水量、日照时数，受影响较大的生育时期是前期和中期，而生育后期气象条件相似，播期间生育日数相差较小；花生的生育时期以有效积温法来预测。

To explore the effect of sowing date and meteorological elements on growth and yield of peanut cultivar Xianghua 2008 , a sowing trial was conducted in Shaodong County .The results showed that the pea-nuts with different sowing dates experienced different weather conditions , so their growth and development and yield were affected .The recommended optimum sowing date was early April .Meteorological elements had greater effects on development process of peanut , which were in order of total cumulative temperature , air tem-perature , precipitation and sunshine duration .Early and medium growth stages were more affected by meteoro-logical conditions , while later growth stage was less affected in similar meteorological conditions between differ-ent sowing dates .The growth period of peanut might be predicted by effective cumulative temperature .
