北京小麦进入收获期,较2013年提前7~10d。为保夏粮丰收,并为秋粮生产腾出时间,2014年北京三夏生产“抢”字当头。2014年夏粮生产形势复杂。冬小麦适播面积提高7.9个百分点,主推品种覆盖率提高4.6个百分点。前期夏粮长势、苗情、穗数好于常年。但受5月初极端低温、下旬持续干热风和5月31日狂风暴雨等不利天气影响,造成穗粒数减少、部分麦田大面积倒伏。
Beijing wheat entered the harvest period, 7 to 10 days earlier than 2013. In order to ensure the good harvest of summer grain and make time for autumn grain production, in 2014, Beijing Sanxia produced “grab” word. The situation of summer cereal production in 2014 is complicated. The area suitable for winter wheat increased by 7.9 percentage points, and the coverage of main push varieties increased by 4.6 percentage points. Pre-summer grain growth, seedling, spike number better than perennial. However, affected by adverse weather such as extreme low temperature in early May, continued dry hot wind in late October and stormy weather on May 31, the grain number per spike decreased, and some wheat fields lurched over a large area.
