摘要
通过普查、抽样调查、定点观察、孢子捕捉、病原菌分离培养、致病性测定等方法,查明了毛竹丛枝病在广西的分布、危害和损失情况,证实竹瘤座菌Balansiatake(Miyake)Hara是毛竹丛枝病的病原,明确了该病的症状特点和主要发生流行规律。分生孢子主要通过风雨吹溅传播;3月下旬～5月中旬,平均温度20°C左右,相对湿度80%以上,是病害发生流行的主要季节;竹尖胸沫蝉AphrophorahorizontalisKato是毛竹丛枝病的传播媒介;昆虫等造成的伤口是病菌侵入的主要途径;新竹当年即可感染发病。
<Abstrcat>The ways of extensive survey,sample survey,fixed point observation,spore catching,isolation,culture and pathogenicity of pathogen were used to investigate the distribution,damage,symptom and epidemic trait of mao bamboo witches' broom in Guangxi.The results showed that Balansia take(Miyake) Hara was the pathogen of mao bamboo witches' broom. Spores of the pathogen were spread by windy and rain-spilt.The main epidemic time of the disease was from later March to mid May when the average temperature was about 20°C and relative humidity upwards 80%.Aphrophora horizontalis was vectors of the disease. The biting sopt of the insect was the main invasive entry of the pathogen. Newly cultivated bamboo could be infected in a year.
