因细绿萍具有速生高产,适应性广,利用途径多的优良特性,目前已成为我省广泛推广的红萍品种。但是,由于这个品种利用年限较长,近几年来,在细绿萍越冬保种和养殖期间易发生霉腐病,不同程度地影响了养萍的发展。 细绿萍发生霉腐病后,萍体布满纵横交错的白色菌丝,或形成白色丝绒状菌落,如不及时防治,受害萍体迅速变黑死亡。霉腐病主要是由萍体带菌和空气传播。一般认为高温多湿,光照不足,通风透气不良,萍层过厚,不及时分萍或虫咬伤口等则有利于霉腐病的发生。 细绿萍霉腐病的防治措施主要是: 1.更换新萍种。不同萍种抗霉腐病能力不同。
Due to its advantages of fast growing and high yield, wide adaptability and many utilization routes, Fine Lupin has now become a widely used Hongping variety in our province.
