Because the accumulation of dry matter at the full heading stage of rice is only one third completed, and two thirds are completed after heading. In some years, the early rice had a good appearance in the early stage. Due to the poor meteorological conditions at the filling stage and the prevalence of the diseases, the quality deteriorated and the yield decreased. In some years, although the early stage was generally normal, the meteorological conditions during the filling stage were excellent, the disease was well controlled and the production management properly , Can still get high yield, so, late rice filling
