今年夏天我国北方大部分地区发生了严重的夏伏旱。黑龙江、吉林、辽宁三省以及内蒙古中东部地区作为我国最大的玉米产区,玉米产量占全国玉米总产量的40%左右。此次干旱发生在玉米作物的灌浆期,干旱导致了玉米灌浆期缩短,籽粒不饱满,进而直接影响玉米的质量和产量,此次旱情对东北地区玉米生产影响较大。
This summer, a serious summer drought took place in most parts of northern China. As the largest maize producing area in China, the three provinces of Heilongjiang, Jilin and Liaoning and the eastern and central regions of Inner Mongolia occupy about 40% of the total corn output in China. The drought occurred during the filling stage of the maize crop. The drought led to shortening of grain filling stage and insufficient filling of grain, which directly affected the quality and yield of maize. The drought affected maize production greatly in northeast China.
