Warm and ample sunshine and good soil moisture benefited from widely rainfall stabilized or improved winter wheat in the Northern. Southern growing areas remained warm in the earlier winter, which provided positive production prospect for winter crops and fruit tree. From late January to February, seriously cold temperature and little illumination controlled the South. The average temperature was the lowest in the same period since 2009, and the precipitation had been the most since 1961.
