| 摘 要： | 2016年7月22至8月2日、8月10-25日湖北省先后出现两段持续晴热高温天气,对湖北省中稻抽穗扬花和灌浆造成了一定影响.据调查,湖北省大部中稻都遭遇了抽穗扬花期高温热害,结实率下降明显.部分中稻灌浆期再度遭遇高温热害,千粒重也有所下降,2016年夏季高温热害对湖北省中稻产量有较明显的影响.除了高温热害,前期的梅雨期暴雨洪涝也对中稻产量产生了一定影响,造成分蘖期受淹.有效穗减少,也是产量下降的原因之一.

| Abstract: | In July 22th to August 2nd and August 10th to 25th,continuous heat damage appeared twice,which had a certain effect on the flowering and filling stage of middle rice of Hubei.According to the results of middle rice's yield survey,the most middle rice suffered heat damage in flowering stage,which led to the significant reduction of seeding rate.Part of the rice suffered heat damage again in filling stage and that resulted to the reduction of grain weight.In general,the heat damage in summer of 2016 made a relatively significant impact onto the yield of middle rice in Hubei province.Besides,rainstorm flood in plum rain period had also a certain impact on the yield of rice,especially the flood happened in tillering stage which led to the reduction of effective spike.This was another reason for yield reduction of middle rice in Hubei. |
