dc.description.abstract | Predmet ovog rada je optimizacija ujednačenosti isejavanja semena korišćenjem metode odzivnih površina i provera optimalnog nivoa promenljivih. Promenljive su modelirane kao potpritisak na setvenim pločama, prečnik setvenih otvora i periferna brzina setvenih ploča. Metoda može da se koristi za optimizaciju međusetvenog rastojanja svih ratarskih i povrtarskih kultura za čiju setvu se koristi pneumatska sejalica sa potpritiskom. Modeli su shodno usvojenim koeficijentima važeći za brzinu rotacije setvenih ploča od 0.053 m·s-1 do 0.192 m·s-1, za prečnik otvora na setvenim pločama od 1.66 mm do 3.34 mm i za potpritisak na setvenim pločama od 2.64 kPa do 9.36 kPa. . | sr |
dc.description.abstract | The subject of this paper is to optimize the uniformity seeding distances using response surface methodology and validated optimal level variables. Variables are modeled as a vacuum on the seed plate, diameter planting holes and peripheral speed of sowing records. The method can be used to optimize seeding distance of field and vegetable crops for which sowing is used pneumatic vacuum seeding machine. The models are valid for the speed of rotation of the plate seeding 0.053 m·s-1 to 0.192 m·s-1, the diameter of the holes in the seed plate from 1.66 mm to 3.34 mm and the vacuum of the seed plate 2.64 kPa to 9.36 kPa. Accuracy seeding distance depends on the diameter of the holes in the seed plate. The optimum value of about 3 mm in diameter is used for cotton seeds in the experiment. The level of vacuum pressure is important and connected with a diameter holes and the choice of its optimal level based on the physical properties of the seeds is about 5.5 kPa. . | en |
