Özet
Bu tezde klasik ilaçlama ünitesi olan tekli meme ile yanlardan püskürtme yapan ikili püskürtme ünitesi iz maddesi tutunması ve damla büyüklüğü karakteristik değerleri açısından incelenmiştir. İz maddesi olarak Tartrazin boyası kullanılmış ve filter kağıtları üzerine her iki unite ile ayrı ayrı farklı basınçlarda (2-3-4 bar) püskürtme yapılmıştır. Ayrıca damla büyüklüğü karakteristiklerinin tespiti için suya duyarlı kağıtlardan faydalanılmıştır. Hacimsel ortalama damla büyüklüğü, sayısal ve yüzeysel ortalama damla büyüklüğü değerleri hesaplanmıştır. Ayrıca yaprak alanına gelen damla sayıları da belirlenmiştir. Hedef alan olarak domates bitkisi seçilmiştir. Örnekleme yüzeyleri domates bitkisinin üst kısmına, alt kısmına ve toprak yüzeyine yerleştirilmiştir. Araştırma sonucunda ikili püskürtme ünitesi daha iyi sonuçlar vermiştir. Yaprak altı bölgelerde ikili püskürtme ünitesi daha başarılı olmuştur. Spektrofotometrik analizler sonucunda yaprak yüzeylerinde en fazla iz maddesi tutunumu ikili meme ünitesinde elde edilmiştir. Yaprak yüzeylerinde ve alt kısımlarda ölçülen damla çapı değerleri açısından püskürtme üniteleri arasındaki fark önemlidir. Yaprak alanı indisi küçük bitkiler için tekli püskürtme ünitesi önerilirken büyük olanlara ikili püskürtme üniteleri önerilmiştir.
In this thesis, different spray nozzle units, the unit with one nozzle which is classic spray unit and the unit with two nozzles which is sprayed on both side of plant, were compared in relation to spray deposition and droplet characteristics. Different pressures were applied 2-3-4 bar. Tartrazine was used as tracer. Filter Papers were placed for determination of spray deposition. Water Sensitive Papers were placed for determination of droplet characteristics. Volume median droplet diameter, numerical median droplet diameter, space mean droplet diameter and homogenous coefficient were calculated as droplet characteristics. Also Leaves area index for application was determined. Tomatoes were selected as target plant. Papers were placed on the topsides, undersides of leaves and the ground. In conclusions, the unit with two nozzles was the most successful in terms of the spray deposition on the undersides of leaves. As a result of spectrofotometric analysis the biggest spray deposition was occurred in the unit with two nozzles. The difference between the spray units in term of drop diameter degree which was measured on the surface and under the leaves are important. The units with one nozzle were suggested for plants have a small leaf area index . But the units with two nozzle were suggested for plants have a small leaf area index.
