去年入冬以来,我国冷空气活动频繁,大部分地区气温比常年偏低,长江流域多次出现雨雪冰冻天气过程,导致油菜冬季生长缓慢,部分田块渍害和草害较重,一类苗比例下降,二、三类苗比例上升。春季是油菜快速生长时期,也是产量形成的重要时期。为此,抓住春季气温回升的有利时机,加强田间管理,是夺取今年夏油丰收的关键一环。

Since the winter of last year, cold air activities in our country have been frequent, and the temperatures in most areas have been lower than normal. The rain and snow in the Yangtze River basin have experienced many freezing and freezing weather processes, resulting in the slow growth of canola in winter, heavy stains and grass weeds in some plots, The proportion of seedlings dropped, and the proportion of two or three types of seedlings went up. Spring rapeseed is a period of rapid growth, but also an important period of production. To this end, grasping the favorable opportunity of the spring temperature pick-up and strengthening the management of the fields will be the key to seizing the harvest this summer.
