摘要
利用周口市夏玉米、大豆、棉花定点观测地段数据,结合大田调查情况,分析2011年9月5～20日周口市连阴雨对该市作物生长的影响情况,并提出生产建议。结果表明,此次连阴雨伴随低温寡照不利天气条件,此时周口市秋作物正处于产量形成的关键时期,秋季连阴雨不利于作物光合作用和灌浆进行,造成玉米出现早衰、百粒重下降、产量下降、收获期推迟,大豆产量稍受影响、发育期推迟,棉花品质较差、产量较低、发育期受影响较小。针对此次过程的影响结合周口市当地的实际,提出相应的对策,以期对以后的秋季连阴雨天气的防范工作有所帮助。
By using observation data of summer maize,soybean,cotton,combining with field investigation,the effects of Zhoukou continuous overcast rain on crop growth in Zhoukou City during Sep.5-20,2011 were analyzed.The results showed that the continuous overcast rain accompanied with hypothermia and less sunshine had a bad influence on the main autumn crop which includes maize cotton and soybean.The adverse effects were as follows： firstly,crop photosynthesis and grouting could not be normal running.Secondly,maize appeared premature senility,kernel weight and yield decreased,harvest delayed.Thirdly,Soya bean yield was slightly affected,while growth period was delayed.Lastly,cotton＇ quality was poor,the yield was low,while the growth period are less affected.Aiming at the influence and actual situation,corresponding countermeasures were put forward,so as to provide help for prevention of autumn continuous overcast rain in the future.
