陈永康同志在晚稻丰产栽培中不仅重视合理施肥,并且十分重视合理控制稻田光照,从他的经验中可以明确:掌握晚稻群体的适时封行,是稻田控制与利用光照条件的关键,并且还是调节群体与个体关系,解决高产与倒伏的矛盾的重要基础之一。 我们几年来与陈永康同志一起参加晚稻丰产田的生产实践,并围绕他的“适时封行”经验进行研究,研究结果已开始在苏南太湖地区广泛介绍推广。现将有关成果综合报导于下。 Comrade Chen Yongkang not only paid attention to rational fertilization in the cultivation of late rice, but also placed great emphasis on the reasonable control of the light in paddy fields. From his experience, it is clear that mastering the timely sealing of the late rice population is the key to controlling and utilizing light conditions in paddy fields, And one of the important foundations to solve the contradiction between high yield and lodging. In recent years, with Comrade Chen Yongkang, we participated in the production practice of late-cropping high-yielding fields and conducted research on his experience of “timely sealing”. The research results have been widely introduced and promoted in Taihu Lake in southern Jiangsu. The relevant achievements are reported below.
