摘　　要：芦笋茎枯病是芦笋上的一种重要病害,发病重的成片枯死.经鉴定,江西省芦笋茎枯病的病原菌为 Phomopsis asparaqi(sacc.)Bubak.研究表明:遗留在田间病残体多、土质粘重、排水不良,氮肥施用过量,发病重。温度24～27℃、相对湿度96%以上,有利于发病。彻底清除田间病残体,地势较高的砂壤土,高畦种植,用地膜覆盖、可减轻发病;从不同施肥和药剂防治试验中筛选出腐植酸氮、磷、钾复混肥和防霉宝、能有效防治芦笋茎枯病,提高了产量和品质.Stem blight is a major disease in asparagus.It will cause the death of the asparagus on the whole plot in searious cases.The pathogenicity was identified as phomopsis asparagi (sacc.) Bubak.in Jiangxi province,the results of the research showed:large quantity of in- fected plant residues,great viscosity and heaviness of soil.pool drainage condition and over use of nitrogen would worsen the disease;meanwhile,temperature of 24-27℃ and relative humidity of 96% were the favarable conditions for its occurrence.Complete elimination of the infected plant residues,growing the aspargus in sandy soil in higher places by means of high ridges and covering the soil surface with plastic sheet would reduce the occurrence of the disease.Using humus acid N.P.K blended as fertilizer and spraying carfen dazim hydrochloride could control the stem blight in asparagus effectively,hence increasing its output and bettering its qulity.
