摘　　要：寒地水稻生育期短、热量资源差、返青期长,培育壮苗是保证秧苗移栽后早生快发进而早熟增产的重要环节;但在生产过程中,常因苗床管理不当或不利自然因素造成秧苗素质变差,最终导致产量降低。介绍了寒地水稻苗床管理关键措施,分析了苗床管理误区,总结了苗床常见病害的发病原因及防治方法,旨在为科学育苗提供技术支持。In cold region,rice has short growth period,poor heat resources and long regreening period.The cultivation of strong seedlings is an important link to ensure early growth and rapid growth of seedlings after transplanting,and then early maturity and yield increase.However,in the process of production,the quality of seedlings is often deteriorated due to improper management of seedling beds or adverse natural factors,which eventually leads to the reduction of yield.This paper introduced the key measures of rice seedling bed management in cold region,analyzed the misunderstandings of seedling bed management,summarized the causes of common diseases and their prevention and control methods,in order to provide technical support for scientific seedling rearing.
