【摘要】：2016/2017年冬小麦、油菜生育期内,主产区大部时段光热充足、墒情适宜,气象条件总体好于2015/2016年和常年,利于夏收粮油作物生长发育。江淮江汉连阴雨造成小麦播期偏晚、长势弱,气温偏高导致北方小麦冬前旺长,灌浆后期受强降雨和大风影响,部分小麦出现倒伏。长江流域部分油菜产区阶段性阴雨寡照,不利于油菜健壮生长和抽薹开花,影响产量形成。
[Abstract]:In the winter wheat and rapeseed growing period of 2016 / 2017, the main producing areas had sufficient light and heat, suitable moisture, and the meteorological conditions were better than those of 2015 / 2016 and all the year, which was favorable for the growth and development of grain and oil crops in summer. The continuous overcast rain in Jianghan of Jianghuai River caused the late sowing date, weak growth and high temperature, which led to the prolificacy of winter in the north, the strong rainfall and strong wind in the late filling stage, and the lodging of some wheat. In some rapeseed production areas of the Yangtze River, it is not conducive to the robust growth and bolting and flowering of rapeseed, and affects the formation of yield.
