防御寒地水稻冷害的施肥技术研究现状

Research Advances on Fertilization Techniques against Cold Injury to rice in Cold Regions

冷害是水稻减产的主要原因之一,也是全世界普遍关注的问题,尤其寒地稻作区,低温冷害频繁发生。本文简要介绍了测土配方施肥、控制氮肥的施入、增施磷肥、增施钾肥、施用有机肥和微肥对防御低温冷害的作用,并对今后寒地水稻冷害防御的施肥技术方面研究提出了一些建议。

Cold injury is one of the most important factors to decrease the yield of rice,which is the concerns of world rice production.Cool injury of rice occurs often in cold region.The problems concerning fertilization techniques of cold injury prevention were discussed in cold regions,and the suggestion was put forward for the prevention of cold injury to rice.
