稻田遗留菌核存活率的研究

The Survival of Remaining Sclerotia in the Rice Field

稻田遗留菌核存活试验表明，稻田土表和土下２ｃｍ、５ｃｍ处菌核，经过夏季高温和泥水沤淹全部腐烂，丧失生命力；田埂顶部和半坡处菌核，分别约１／３和１／１０具有生命力。

The results indicated that the sclerotia all rotted on the top soil and in 2cm and 5cm depth of subsiol in rice field, 1/3 survived on the top of the field ridges and 1/10 survived on the slop of the field tidges.
