Abstract :
In this paper, the design and the results of a microwave radiation system for agriculture applications is discussed.
The system is fabricated and successfully tested on weed seeds. The device, which uses a commercial 1 kW
magentron, proved to be effective for preventing the germination control of popular weeds of Iran. Seven weed
species were tested separately by using this system and then the irradiated soil was cultivated in a greenhouse.
The results show that by increasing soil temperature up to 70 oC, the germination rate of weed seeds is less than
20 percent (in some cases zero percent). It should be mentioned that the safety of the system is also studied
according to ICNIRP standard.

در اين متن، طراحي و نتايج سامانه تابشي مايكروويوي براي كاربردهاي كشاورزي مورد بحث قرار گرفته است. سامانه با
موفقيت ساخته و آزمايش شده است. اين سامانه كه از يك مگنترون 1 كيلووات استفاده مي كند. 7 نوع علف هرز رايج در
ايران توسط دستگاه مورد آزمايش قرار گرفته و سپس در گلخانه كشت شده است. نتايج نشان داد كه با افزايش دماي خاك
تا 70 درجه سلسيوس، جوانه زني آنها به كمتر از 20 درصد مي رسد )در برخي موارد نزديك به صفر(. قابل ذكر است كه
ايمني اين دستگاه با استفاده از استاندارد ايكنيرپ مورد بررسي قرار گرفته است.
