1 发生原因 线虫病的发生与品种、气候、耕作方式密切相关。 1.1 种子传播是线虫病主要途径。线虫病主要传播途径是种子。其形成原因,一是思想上不重视,谷子连年做种,带病植株多,造成了潜在病原。二是播种前。不进行药剂拌种造成恶性循环。三是粮农对线虫病不认识,束手无策。 1.2 开花灌浆期高温多雨是造成线虫病大发生的主要原因。开花灌浆期是线虫为害盛期,而高温多湿是线虫繁殖的有利条件,特别是夏谷抽穗灌浆期多风多雨,线虫在风摇谷穗碰撞及雨水冲洗
1 causes of nematode occurrence and species, climate, farming methods are closely related. 1.1 Seed transmission is the main route of nematode disease. The main route of transmission of nematode is the seed. The formation of the reasons, one thoughtless attention, millet year after year, sick plants, resulting in a potential pathogen. Second, before sowing. Pharmacological dressing without causing a vicious cycle. Third, food and agriculture do not know nematodes, helpless. 1.2 flowering filling high temperature rainy is the main reason for the occurrence of nematode disease. Flowering filling stage is the nematode damage period, and high temperature and humidity is the favorable conditions for nematode reproduction, especially in the summer grain heading stage windy and rainy, nematodes in the wind shaking the ears and rain irrigation
