利用空中孢子捕捉器定时捕捉大气中的病菌孢子,是预测病害发生发展的有效手段。从1978年开始,我们在稻瘟病的中期预报中使用BH—8型电动自控启闭式孢子捕捉器(浙江省黄岩县头陀电器厂产品,现已定型),经二年的实际应用,初步认为它性能稳定可靠,灵敏度较高。 这种孢子捕捉器由捕捉装置和自控装置二部分组成。 捕捉装置的特点是载玻台能自动启闭,即在转臂两端各装有一活动载玻台(内可插入载玻片,玻片四周不外露),其下端有个载玻台垫与转臂连在一起;静止时载玻台平伏在台垫上,呈闭合状。工作时载玻台由于
The use of aerial spore catches regularly capture bacteria in the air spores, is an effective means to predict the occurrence of disease development. Since 1978, we have used the BH-8 electric controlled open-close spore catcher in the medium-term forecast of rice blast (the product of Tiantuo Electrical Appliance Factory in Huangyan County of Zhejiang Province has been finalized). After two years of practical application, we initially think It is stable and reliable performance, high sensitivity. This spore catcher by the capture device and automatic control device composed of two parts. The characteristic of the catching device is that the glass platform can be opened and closed automatically, that is, a movable glass platform is installed at each end of the iron cylinder (the glass can be inserted into the glass and the glass is not exposed all around) Swinging arms connected together; still when the load-bearing platform in the pad, was closed.
