返青期没顶淹水对粳稻生长及产量的影响与对策
Effects and Countermeasures of Waterlogging on Growth and Yield of Rice at Regreening Stage
摘要
Abstract
In order to explore the effects of complete plant submergence at regreening stage on growth and yield of japonica rice, the authors conducted a systematic investigation. The results showed that, with the increasing of complete plant submergence duration at regreening stage, the plant height decreased, initial heading stage delayed, the effective panicles, grains per panicle, thousand grain weight and yield decreased. The longer the flooding last, the deeper of the damage would be. But the rice plant can be utilized within 5-days of submergence. Severe flooding field could choose the short growth period varieties with machine transplanting or water direct seeding.关键词
