新疆苜蓿病害研究现状与展望

苜蓿病害是限制新疆苜蓿产业可持续发展的关健因之一,长期以来许多学者围绕苜蓿病害进行了多方面研究。迄今,新疆已报道苜蓿病害24种,病原35种。其中仅对苜蓿黄萎病菌、苜蓿褐斑病菌、苜蓿立枯丝核菌、苜蓿霜霉病菌、苜蓿白粉病菌的生物学特性,苜蓿褐斑病、苜蓿霜霉病、苜蓿白粉病的发病规律和影响因子做了部分研究,其余病害规律及病原特性尚缺乏研究。就新疆苜蓿病害的种类、病原及生物学特性、发病规律及防控措施研究进展进行了综述,并展望了新疆苜蓿病害的研究前景。

Progress and Prospect on Alfalfa Disease in Xinjiang

Alfalfa disease is one of major factors which hinders the sustainal development of alfalfa industrial of Xinjiang,so studies on Alfalfa disease have been carried out for many years.Up to now,24 alfalfa diseases and 35 pathogens were reported.Among them,biological characters of Verticillium albo-atrum,Pseudopeziza medicaginis,Rhizoctonia solani,Peronspora aestivalis,Leveillula leguminosarum and the laws of Brown spot,Downy mildew,Powdery mildew were researched partly,but the others are waiting for research.In this article,the studies on kinds of disease,identification of pathogens,biological character,disease law and control on alfalfa disease were summarized.Moreover,some questions and countermeasures were raised.
