为摸清伊贝母菌核病在伊犁巩留县的发生规律,为开展综合防治提供依据,通过田间调查及室内分离培养等方法,确定伊贝母菌核病病原为Stromatinia rapulum (Bull) Boud,属于子囊菌亚门、盘菌纲、柔膜菌目核盘菌科、座盘菌属。病原在15~20℃条件下培养,第10天开始产生菌核,在20℃时产生的菌核数量最多。4月底至五月中旬均可发生,在低温多湿、地势低洼、排水不良的条件下极易发生。以菌丝或菌核在土壤病残体或病鳞茎上存活,成为初次侵染。
In order to find out the regularity of the occurrence of Iberian Mycosis in Gongliu County, Yili County, and to provide the basis for the comprehensive prevention and control, the pathogen of Iberian Sclerotinia was identified as Stromatinia rapulum (Bull) Boud , Belonging to Ascomycetes subfamily, Oyster ganglion, Membranous fungi nuclear sclerotinia, Sclerotinia. Pathogen culture at 15 ~ 20 ℃ conditions, the first 10 days began to produce sclerotia, at 20 ℃ produced the largest number of sclerotia. The end of April to mid-May can occur in low temperature and humidity, low lying, poor drainage conditions easily occur. With mycelium or sclerotia in the soil disease or disease bulbs survive, become the first infection.
