水稻温室无土育秧具有成秧率高,不受早春恶劣气候影响,秧苗齐壮,用工用肥用种节省等许多优点,为提高粮食产量起了重要作用.但是,温室秧苗“窝团烂根”病害的发生,直接关系到温室育秧的成败.自1979年以来,我们通过调查观察和试验研究,基本摸清该病的致病原因和发生规律,掌握了防治方法,并在近两年推广运用中,取得了初步成效. Rice greenhouse soilless seedling has the characteristics of high seedling rate, not affected by the bad weather in early spring, seedling sturdy, labor and fertilizer used to save many advantages, to improve grain yield has played an important role .However, "The occurrence of diseases is directly related to the success or failure of greenhouse seedling cultivation. Since 1979, we have basically found out the causes of the disease and its occurrence through investigation and experimental studies, mastered the methods of prevention and treatment and promoted it in the past two years In use, we have achieved initial success.
