“秋分”前后,晚稻进入齐穗期。晚稻齐穗后,有的农户认为晚稻产量已成定局,自觉或不自觉地放松了晚稻后期的管理,这是不妥当的。因为晚稻齐穗期干物质的积累仅完成三分之一,还有三分之二是在齐穗后完成的,有的年份晚稻前期长相较好,但由于灌浆期气候条件差,若放松后期管理,加上病害流行,就会使晚稻品质变差,产量下降。也有的年份虽然晚稻前期长相一般,但灌浆期气候条件优越,病虫害防治效果好,后期管理得当,仍然获得高产。所 “Autumn” before and after the late rice into full heading period. After the full rice harvest, some farmers think that late rice production is a foregone conclusion, consciously or unconsciously relaxed late rice management, it is not appropriate. Because the accumulation of dry matter in late rice at heading stage only completed one-third, and two thirds of them are completed after heading, some of the late rice looks better late, but due to poor weather filling stage, if the late relaxation period Management, coupled with disease epidemics, will deteriorate the quality of late rice and reduce yields. In some years, although the early rice has a general appearance in the early stage, the climatic conditions at the filling stage are superior, the pest and disease control effect is good, and the latter part of the project is properly managed, and the yield is still high.
